A dietary approach to prostate health

A dietary approach to prostate health

A dietary approach to prostate health

The awareness of men’s health has become more visible in recent years with the help and awareness driven by organisations such as the Movember Foundation, which have made the topic more accessible with their brilliant approach that resonates perfectly with men of all ages.

Prostate health

There are numerous health issues related to men, which encompass both mental and physical health and include conditions such as infertility, impotence, depression, overweight and those related to the prostate. Despite the raised awareness, many men still find it difficult or embarrassing to seek help and this is heavily influenced by social stigma, which is a key consideration in the promotion of men’s heath as it creates a barrier to men seeking help and advice.

Prostate health is unique to men and is typically correlated with age given that conditions associated with it mostly affect male baby boomers (aged 54-74 years) and Gen X (aged 39-53 years).  Diet and lifestyle have a key role to play in prostate and many other areas of health and establishing good habits from an earlier age will pave the way to better health in the long-term.

What is the prostate?

The prostate is a small gland about the size of a walnut, which surrounds the tube (urethra) responsible for carrying urine out of the body and also secretes fluid that nourishes and protects sperm.

Common prostate health complaints include benign prostatic hyperplasia (BPH) or enlarged prostate.  The prostate gland naturally continues to grow with age but can cause troublesome symptoms in men with BPH, which make it difficult to urinate and empty the bladder.  Other prostate heath conditions include prostatitis (inflammation of the prostate, which can occur from the age of 30) and prostate cancer, which incurs more than 40,000 newly diagnosed cases every year in the UK making it the most common form of cancer amongst men.

Symptoms of both BPH and prostate cancer are similar given they are both related to an enlarged prostate and include:

  • Frequent urination
  • Weak or interrupted urine flow or the need to strain to empty the bladder
  • The urge to urinate frequently at night
  • Blood in the urine
  • Blood in the seminal fluid

Prostate cancer

Prostate cancer is a big health issue amongst men but is slow to develop meaning symptoms may not occur for many years until the prostate is large enough to affect urination.  An enlarged prostate does not mean you have cancer, but the symptoms shouldn’t be ignored.  The causes of prostate cancer are largely unknown, but the risk is increased beyond the age of fifty and for reasons as yet unclear the disease appears to be more common in men of African-Caribbean or African descent.  There also seems to be a slight increased risk in men with a family history of prostate cancer.

A reliable method of screening for prostate cancer is yet unavailable and early detection relies on vigilance about symptoms and regular check-ups with your GP.  A blood test called prostatic-specific antigen (PSA) test is available but is not specific to prostate cancer and PSA levels can be raised as a result of other non-cancerous conditions.  If you have raised PSA levels, then you may be offered an MRI scan to help further diagnose the risk of cancer.

Men’s attitudes to health

Research has shown how men are less likely to engage and react to healthcare information or recall the warning signs of cancer when compared to women (1,2). The cultural script of men has imprinted a definition of masculinity characterised by a need to be tough, brave, strong and self-reliant, which can influence their attitudes towards seeking help and overall self-care. Phrases such as ‘man up’ are now common place in our lingo used by men and women alike and are a good example of how this characterisation of men continues to be enforced.

Boys from an early age are often led to believe that if they don’t exhibit these characteristics of the ‘traditional’ male then they will in some way lose their status and respect as men, which contributes to many of the issues surrounding men’s health.  Kids story books and animated movies are riddled with such characterisations of princes and superheroes relied upon to save the day, which is often (rightly) fiercely protested against by women seeking equality but is less considered as to the impact on young men and the contribution to social stigma putting pressure on men to behave in a certain way.

The importance of diet on health

Research convincingly shows that people who eat a healthy diet are more likely to live longer and have a reduced risk of disease, but the link between diet, food and specific health conditions is often less clear.  It’s the overall diet that has the greatest impact on health but in the case of prostate health there are some studies to suggest that certain foods and nutrients may be particularly beneficial.  Most of these benefits can be achieved by eating a healthy balanced diet but introducing certain foods may be worth paying some consideration to.

How can diet help with prostate health?

I don’t want to sound boring, but you have to get the basics right first.  The modern dialogue around nutrition is overly focused on individual nutrients and foods, whilst the nature of the current wellness landscape gives more credence to the latest fads and diet trends over the basic principles of healthy eating.  Focusing on eating a balanced diet can help insure micronutrient intake and also help you to maintaining a healthy body weight, which is one of the best things you can do to reduce your risk of ill health.  This is particularly relevant to prostate cancer as findings from the World Cancer Research Fund (WCRF) have shown a strong association between being overweight or obese and the risk of developing the disease (3).

Start with the basics

Start by eating three meals daily and cutting out snacks unless you really need to include them.  Pile the veggies high, limit your intake of red meat, switch to ‘brown’ carbs and wholegrains, choose healthy fats (olive oil, avocados, nuts, seeds), cut back on sugar, watch your salt intake and serve small portions of food to help manage your weight.

Eat more salmon

Oily fish such as salmon are the richest source of omega 3 fatty acids, which we need to obtain from the diet.  Intake of oily fish in the UK is low with very few people including this food in their diet.  Omega 3 fatty acids have been shown to help reduce inflammation in the body, which may help to relieve the symptoms of BPH.  Salmon fillets can be marinated to make them more interesting or added to dishes such as fish pie, curry and salads.

Get more fibre in your diet

High-fibre foods include fruits (fresh and dried), vegetables, wholegrains, nuts, seeds, beans, pulses and lentils. According to the National Diet and Nutrition Survey only 13% of men meet the recommended dietary guidance of 30g per day and this is most likely due to choosing refined carbohydrates, not eating enough vegetables and ignoring foods such as beans and pulses (4).  Dietary fibre can help to reduce the risk of constipation, which can put pressure on the bladder and worsen symptoms of BPH.  Eating more fruits and vegetables is probably the easiest and most effective change you can make to your diet to significantly improve your health.  Many foods in this group contain a good source of vitamin C, which is also thought to help relieve the symptoms associated with BPH (5). Most of us get more than enough vitamin C in our diet but foods such as berries, peppers, citrus fruits, broccoli and cauliflower are good sources.

Cut down on fizzy drinks, alcohol, caffeine and artificial sweeteners

You should try and avoid drinking anything up to two hours before bedtime to lessen the need to use the bathroom during the night. Fizzy drinks, alcohol, caffeine and artificial sweeteners can all irritate the bladder and worsen the symptoms of BPH so you should try limiting your intake of these types of drinks.

Eat foods rich in beta-sitosterol

Foods rich in a plant substance called beta-sitosterol have been shown to reduce the symptoms of BPH including urinary flow and volume and may help to lessen the effects of inflammation and prostate growth. Foods rich in beta-sitosterol include seeds, extra virgin olive oil, avocado, nuts, raw cacao and fresh coriander.

Include soy foods as part of your diet

There’s a little research to suggest that phytoestrogens (plant compounds that mimic the effect of the hormone oestrogen) found in soy called isoflavones may help to relive the symptoms of BPH.  Soy isoflavones can be found in foods such as tofu, soya milk, soya yoghurt, miso, tamari, edamame beans and tempeh.  These foods have also been shown to help reduce cholesterol, making them a healthy addition to the diet and are a great alternative to animal protein for those looking to go meat-free. Swapping dairy products for soy is the simplest way to start including it in your diet.

Soy is one of the most controversial foods and you may have heard of the research linking it to the growth of ‘man boobs’.  Firstly, the effect of plant oestrogens on hormonal balance is weak and secondly, the research involved the consumption of unrealistically huge amounts of soy milk every day.

Eat plenty of foods rich in zinc

This mineral is very important for men, who have a higher daily requirement than women.  Zinc is essential for male reproductive health, which includes proper prostate function.  Research has suggested that men suffering with BPH and prostate cancer may have lower levels of zinc, but this is not considered a risk factor for either condition.  You can get plenty of zinc in your diet by eating foods such as shellfish, meat, pulses, beans, wholegrains, nuts, seeds and eggs.

Red fruits and vegetables

Red fruits and vegetables are rich in the antioxidant phytonutrient lycopene.  Tomatoes are the richest source, especially when cooked or processed but other foods include red peppers, pink grapefruit and watermelon.  Lycopene has long been associated with reducing the risk of prostate cancer but updated findings from the WCRF have downgraded the evidence to support this link from ‘strong’ to ‘no conclusion possible’ in light of the current available research (3).  Lycopene may still be beneficial for prostate health and these new findings don’t mean that it’s suddenly redundant, but only that the new research has made it more difficult to establish a link to prostate cancer.

A healthy balanced diet is important for all areas of health, which includes that of the prostate.  Focusing on food and managing your weight are significant ways to help promote good prostate health and the sooner you adopt healthy eating habits the better.  All men over fifty should be vigilant about recognising the signs of prostate cancer and seek regular check-ups with their GP as a habitual part of their lifestyle.

National curry week 2018 – health benefits of curry

National curry week 2018 – health benefits of curry

National curry week 2018

Curry is a word that typically conjures up an image of late-night dining following one too many beers after work on a Friday night or an unhealthy take-away food, but I’m going to put myself out there as saying this reputation is poorly misplaced.

Any food within a particular context could be deemed as being unhealthy but if you break down the components of curry and remove the beers and comfort eating aspect then what you’re left with is actually very healthy.

The origins of curry

The UK has adopted curry as a ‘national dish’ with thousands of Indian, Pakistani and Bangladeshi restaurants creating British-Asian meals we’ve all become familiar with such as chicken tikka masala, Balti and vindaloo.  The word ‘curry’ was invented by the British when they ruled India and adapted from the Tamil word ‘kari’, meaning sauce.  This word has now become an umbrella term to describe dishes that have originated from the Indian subcontinent, but is a definition reserved for the British.

India consists of 28 states with most of these having their own regional cuisines, few of which include the word ‘curry’.  The curry powder we have been accustomed to wouldn’t feature in your typical Indian kitchen and is a British creation, which was developed by Indian spice merchants.  The closest Indian comparison is a blend called garam masala that tends to be used towards the end of cooking.

Traditional dishes originating or inspired by Indian cuisine are characterised by the extensive use of spices, which define the unique flavour of this cuisine.  Indian cooking also includes many plant foods such as vegetables, pulses and lentils that are also thought to have a multitude of positive health benefits.

Variety is key

India is one of many countries whose mealtimes are a sharing affair, which involves a number of different dishes mostly cooked from scratch. This way of eating not only illustrates the positive impact of eating together and sharing mealtimes but also includes eating a wide variety of foods offering a broad spectrum of nutrients.  It’s a fair argument that such cultures dedicate a lot of time to preparing meals and often have an inherited knowledge of recipes and cooking, which is very different to our time-stretched culture that has become over reliant on quick-fix meals and snacking.  However, drawing inspiration from such cultural dining practices may help to improve the way we tend to eat in the Western world.

The health benefits of spices

Many spices are used in Indian cuisine and also feature as a key component of Ayurvedic medicine, which is one of the oldest of traditional medicine systems originating from India thousands of years ago.  Spices are commonly defined as an aromatic part of a tropical plant, which includes roots, barks, flowers and seeds, most of which are Asian in origin. Advances in scientific research has helped to identify and explain some of the benefits associated with spices and how they may contribute to health and the reduction of disease risk.

Spices fight Inflammation

Inflammation is essential to life and is the body’s natural response to injury or infection.  The flip side is that inflammation can have a harmful effect and research has shown that factors such as obesity, smoking, stress and a sedentary lifestyle can promote inflammation to the point at which is contributes to a variety of diseases (1)

Acute inflammation is characterised by redness, swelling, pain and heat, which is a protective response designed to heal the body and restore normal tissue function.  Chronic inflammation can begin in the same way but morph into a state that lingers over a long period of time, failing to respond to the immune systems attempts to eliminate the problem. This low-level inflammation can also occur even when there is no injury or disease.  When the immune system becomes uncontrolled in this way, white blood cells can attack healthy tissues and organs, setting up chronic inflammatory processes that are thought to play a key part in many diseases such as rheumatoid arthritis, heart disease, diabetes, cancer and even Alzheimer’s.

Alongside maintaining a healthy body weight and making healthy lifestyle choices, diet is thought to have a role to play in helping to reduce inflammation.  Research has shown that spices possess anti-inflammatory properties and whilst the findings are mixed, they’re still promising and suggest a benefit to including these foods in your diet.

Spices act as antioxidants 

Spices along with fruits and vegetables are a key source of natural antioxidants in the diet.  These antioxidants help to reduce oxidative stress in the body, which is caused by a high concentration of free radicals in cells and tissues induced by a number of factors such as excess exposure to UV, stress, polluted food, smoking and adverse environmental conditions. If the body becomes overwhelmed with free radicals and is unable to regulate them it can alter lipids, proteins and DNA, potentially triggering disease.

It’s worth pointing out here that free radicals are a natural by-product of metabolism, which is defined as the chemical processes that occur within the body such as those involved in converting food into energy.  Free radicals are essential to life as the body’s ability to turn food into chemical energy relies on a chain reaction of free radicals, which are also a crucial part of the immune system, which help to attack pathogens (foreign invaders).

The term ‘antioxidant’ is somewhat overused in the health arena and whilst achieving a balance between free radicals and antioxidant intake is key, they shouldn’t be be viewed as a panacea to good health.  Many foods contain nutrients that act as antioxidants and whilst eating plenty of these foods such as spices may help to protect against the damage caused by excess free radicals that can build up in the body, it’s important to make lifestyle changes such as losing weight, stopping smoking, drinking less, managing stress and spending less time in the sun rather than relying solely on such foods and supplements to counteract the impact of these lifestyle habits.

The antioxidant activity of spices is related to their chemical composition, mostly the presence of polyphenolic and other biologically active compounds.  The primary antioxidants and biologically active compounds in spices include flavonoids, phenolic acids, lignans, essential oils and alkaloids (2, 3).  These all behave in different ways such as flavonoids have the ability to scavenge free radicals and form complexes with catalytic metal ions that render them inactive (4).

A source of minerals

All spices are a source of minerals such as potassium, iron, magnesium, calcium and zinc.  Amongst all the minerals in spices, iron exists in the greatest concentration.  This mineral is essential for the production of healthy red blood cells and is the most common nutrient deficiency worldwide.  Food surveys have shown that more than 27% of women in the UK have inadequate intakes of iron in their diet and low levels are compounded by monthly menstrual blood losses (5).  Including spices in your diet can be a really useful way to boost your intake of minerals such as iron.

Reducing salt in your diet

Spices enhance the flavour of food and can help to reduce the amount of salt used in cooking, which is good for people with high blood pressure.  Adding spices to food is also a good way to ‘tantalise the taste buds’ and there are many ways to include these in our cooking in the place of salt.

Interesting ways to include more Indian spices into your diet

  • Add turmeric to scrambled egg
  • Add curry powder to boiled rice
  • Use spices to create rubs and marinades for meats
  • Spices such as cumin and ground coriander work well in salad dressings
  • Try adding curry powder or garam masala to traditional homecooked dishes such as shepherd’s pie for an Indian twist
  • Spice up a jar of tomato cook-in-sauce with Indian spices that could include garam masala, curry powder, mustard seeds, turmeric or fresh curry leaves.
  • Try making homemade cashew nut milk with turmeric (great served hot or cold). Add 100g of raw cashew nuts, 1 tsp of turmeric powder, 1 tsp of ground cinnamon and 2 tsp of honey to a high-powered blender with 500ml of water then blitz until smooth.  You can loosen the consistency by adding more water if you like.
  • Add curry powder or garam masala to basic vegetable soup recipe or even shop-bought fresh soups for an Indian twist.

Plant-based eating

There are many benefits associated with eating more plant-based foods.  As a nation we do not eat enough fruits and vegetables with only a third of people managing to meet the five-a-day guidance (5).  Plant foods also provide a rich source of fibre that has been shown to help with good digestion and reduce the risk of heart disease, colorectal cancer, diabetes and help with weight loss.  In the UK it has been shown that less than 10% of adults achieve the recommended daily intake of 30g per day (5).

Anecdotally, many people find vegetables boring to eat and often say that they don’t enjoy the flavour.  In my experience of cooking with people, I have found that with a little inspiration, even the most disliked vegetables can be reinvented with the use of spices and become something completely different.  Spices can also be used to add an Indian twist to vegetarian dishes.

Indian spices are always a great way to spice food and these are just a few ways to turn a plain old vegetable or vegetarian dish into something that’s irresistibly delicious:

  • Rub cauliflower with curry paste and roast in the oven.
  • Combine a 400g can of chickpeas (drained) with 1 tbsp of garam masala or curry powder and roast in the oven at 180C for 30 minutes.
  • Stir-fry okra with chopped red onion, ginger and cherry tomatoes, and fresh curry leaves.
  • Fry mustard seeds and crushed coriander seeds in a pan with a little oil until they begin to pop. Take them off the heat and stir through blanched green beans with a little oil.
  • I’m always looking for ways to make cooking tofu more enjoyable and found that it lends itself well to Indian cuisine and is a great alternative to paneer. I also discovered recently that you can bake tofu, which gives it a firm meaty texture.  You need to choose extra firm varieties and it can be marinated before or after cooking.
  • Learn to make a basic dhal recipe such as this one from mine and Lily’s cookbook

Healthy curry food swaps

There’s no doubt that many of us choose to eat curry on a night out or as take-away on a night in, but it doesn’t need to be a calorie laden affair.

  • Rather than ordering a meal solely for yourself, opt for sharing and choose plenty of plant-based options such as lentils and vegetables
  • Try choosing tomato-based curries over those laden with cream or coconut milk, which can be high in saturated fat
  • Try choosing oven cooked (tandoor) meats such as chicken and teaming them with vegetable dishes
  • Ditch the breads such as chapatti and naan

The true health benefits of curry are often overshadowed by the reputation this type of food has acquired.  The use of spices and plant-based foods are at the root of the health benefits associated with this the of cuisine.

Try this healthy vegetarian curry recipe, which not only provides many of the health benefits associated with South Asian cuisine but tastes bloody great!

Chocolate can be good for you

Chocolate can be good for you

Chocolate can be good for you

This week is Chocolate Week!!!!

The History of chocolate 

The history of chocolate dates back over 3000 years to the Olmec civilization.  Cocoa powder is made from cocoa beans that are harvested from a tree called Theobroma Cacao, meaning ‘food of the Gods’.  Aztecs are thought to have enjoyed cacao beans by making a ‘drink’ called Chicolati, which was believed to increase wisdom, boost energy and act as an aphrodisiac. This brew was seasoned with vanilla, chilli, honey or fruit and whipped into a froth using little sticks.  I love their choice of flavours, which have now become commonplace amongst chocolate bars and puddings.

Since its discovery by Europeans and the vast time through to modern day, millions of people have helped to drive the popularity of this ultimate sweet treat.  The reputation of chocolate has evolved over time from a luxury food synonymous with wealth, to an easily affordable comfort food whilst the association with romantic gesture (food of love) and mood has remained since first discovered.

Global retail sales of chocolate are staggering with estimates of over £75 billion per year and in the UK alone, we spend over £3 billion annually.

Types of chocolate

Chocolate comes in many forms nowadays and is defined by the percentage of cocoa it contains.  Milk chocolate contains a low percentage of cocoa (23% cocoa solids) and is high in sugar and saturated fat.  Darker varieties have a greater percentage of cocoa (anything from 70-90% cocoa solids) and slightly less sugar and saturated fat (although still high).  Cocoa powder contains hardly any sugar, low amounts of saturated fat and is rich in minerals and other compounds that may benefit health.

Nutritional content of cocoa

Cocoa in its raw form is a good source of minerals including iron (helps to maintain healthy red blood cell production), magnesium (helps to maintain healthy bones, promotes muscle relaxation and converts food into energy), phosphorus (healthy bones and converts food into energy), potassium (helps maintain fluid balance and helps the heart to work properly),  zinc (helps to make new cells and enzymes in the body and wound healing) and copper (helps to produce red and white blood cells and with iron usage in the body).

Copper           0.55mg (55% RDA)

Other compounds found in cocoa

Cocoa is richer in antioxidants that almost any other food on the planet.  These antioxidant compounds are called flavanol polyphenols and have been shown to help reduce the risk of disease. Cocoa also contains a compound called theobromine, which acts as a stimulant similar to caffeine but without the jittery side-effects. You will also find phenethylamine (PEA) in cocoa, which is a compound that stimulates the central nervous system to amplify the action of brain chemicals including the ‘feel’ good hormones serotonin and dopamine.  Phenethylamine is also thought to mimic the brain chemistry of someone in love, which is why it’s often thought of as an aphrodisiac.

What are the potential health benefits of cocoa?

In moderation there’s nothing wrong with eating chocolate within the context of a healthy diet, but too much of anything can have its downsides and our reliance on high sugar snacks has been instrumental in the rise of diet related diseases including obesity.

Whilst overindulging on chocolate snack bars and puddings is clearly not great for your health, research has shown that there may be health benefits associated with cocoa, which is the raw ingredient.

Just to be clear, there are no benefits associated with tucking into a few packets of Minstrels and any positive impact on health is linked to cocoa in its raw form of cocoa powder or raw cacao.  The closest chocolate comes to having any health benefits is the dark variety with a high percentage of cocoa solids (70% and above), but this still needs to be eaten in moderation given its high sugar and sat fat content.

Heart disease

The polyphenols in cocoa are thought to dilate the arteries, which improves elasticity and may reduce the risk of heart attack. The effect of these antioxidants is also thought to be similar to aspirin in that they help to thin the blood and prevent unwanted clots with research showing that the effect after drinking a cup of cocoa lasting more than 6 hours (1).  Findings from a large analysis of seven studies carried out by researchers at Cambridge University found that both men and women with the highest intake of cocao were 37% less likely to suffer with coronary heart disease and 29% less likely to experience a stroke compared to those with the lowest intakes (2).

Cholesterol

Studies have shown that cocoa may have a positive impact on cholesterol, raised levels of which are considered to be a risk factor for heart disease.  Findings from a clinical trial published in the Journal of Nutrition showed that the polyphenols found in cocoa powder contributed to a reduction in LDL (bad) cholesterol, elevation in HDL (good) cholesterol and suppressed the oxidation of LDL cholesterol, which is thought to be particularly damaging to tissues such as those lining the arteries of the heart (3).   The effect on oxidation may be explained by the antioxidant effect of polyphenols as they help to protect the body from free radical damage (4).

Blood pressure

Research around blood pressure stems from islanders of Kuna that don’t appear to develop high blood pressure as they get older, which is in part attributed to the high amounts of cocoa they consume on a daily basis. It was noticed that once they left the island and consumed less cocoa they lost the protective effect on blood pressure.  The link between cocoa and blood pressure is that the flavanols it contains increase the availability of nitric oxide in the blood, which dilates blood vessels and lowers blood pressure.  Researchers from Adelaide University found that drinking cocoa (rich in flavanols) significantly lowered blood pressure when compared to a flavanol-free placebo drink (5).  Similar findings have also been shown in several other studies although the effect is not that strong (6, 7).

Brain health

Studies have shown that drinking cocoa at least 5 days of the week boosts the flow of blood to the parts of the brain that help with cognition and may improve performance and alertness (8).  The antioxidants in cocoa also help to neutralise the low-grade inflammation associated with ‘foggy’ thoughts. Studies of older people that are mentally impaired have found that those who regularly drank cocoa had greater improvements in memory and verbal reasoning than those who did not (9). It’s for this reason that cocoa has been of interest to researchers investigating dementia.

Chocolate as a functional food?

Advances in innovation have seen a rise in chocolate products with added health benefits.  Companies such as Ombar produce a dark chocolate bar fortified with probiotic cultures.

How to add more cocoa into your diet

Whilst many people enjoy eating chocolate and may understand the potential benefit of choosing dark over milk varieties, less people know how to use cocoa powder beyond a drink.

If you’re not familiar with using cocoa powder, then try these ideas below for a little inspiration:

  • Add 1 tbsp to your protein shake.
  • Add 1 tbsp to porridge.
  • Make homemade energy balls by blending cocoa or raw cacao powder, dates and chopped hazelnuts to a food processor.
  • Combine 1 tbsp with hot milk of choice for a warming evening drink rich in magnesium that helps to promote muscle relaxation and has been shown by research to induce sleep. Try adding cinnamon, ground cardamom or chilli for extra flavour.
  • Add cocoa or raw cacao powder to chilli con carne for richness and intense flavour.

The reality of chocolate and health

The truth still remains that chocolate, even dark chocolate, is never going to be considered a healthy food as it contains high amounts of sugar and saturated fat, which if eaten in excess will counteract any potential health benefits of cocoa.  However, you can reap the health benefits of cocoa by incorporating it into your diet in ways that allow you to control the amount of sugar and saturated fat.  It’s also worth pointing out that the true benefit of nutrition lies in the overall diet and not single foods so whilst the health potential of cocoa is interesting, you still need to focus on eating a well balanced and varied diet.

Try this recipe from my book The Detox Kitchen Bible.  These brownies are still a sweet treat but contain much less sugar than usual recipes and harness the benefits of cocoa.

Beetroot Brownies

Makes 9

Ingredients

150g raw beetroot, peeled and cut into small cubes

50g hazelnuts

100g gluten and wheat-free flour

1 tsp baking powder

60g raw cacao powder

120g runny honey

½ tsp salt

3 eggs

75ml rapeseed oil

Method

  1. Preheat your oven to 200°C. Line the bottom and sides of a 20cm square cake tin with greaseproof paper.
  2. Put the beetroot in a microwave-safe bowl with 50ml water, cover with clingfilm and cook on a high heat for 7 minutes until soft. If you don’t have a microwave, wrap the beetroot in foil and bake in the heated oven for about 40 minutes until soft.
  3. Put the hazelnuts in a blender and blitz until they are roughly chopped. Transfer them to a large mixing bowl. Sift in the flour, baking powder and cacao powder.
  4. Now blitz the cooked beetroot in the blender for 1–2 minutes until smooth. Add to the dry ingredients in the bowl but do not mix just yet.
  5. Using the blender for the third time, put the honey, salt and eggs in it and blitz for 3 minutes. Pour into the bowl and mix with the rest of the ingredients using a wooden spoon. Be gentle, as you want to keep air in the mixture whilst combining it thoroughly.
  6. Pour the mixture into the prepared cake tin and bake in the heated oven for about 30 minutes or until a skewer inserted into the centre comes out clean. Allow to cool completely before cutting into squares.

Ten prebiotic foods you need to know about

Ten prebiotic foods you need to know about

Ten prebiotic foods you need to know about

Gut health has become a hot topic in the world of nutrition and as research evolves it’s becoming very clear that the beneficial role of microbes found in the gut goes way beyond digestion.  The collection of microbes in your gut are referred to as your microbiome and advice about how to protect it has become commonplace.

Your gut microbiome is sensitive to your lifestyle and dietary habits; both  can either promote a good diversity of microbes in the gut or tip the balance in the opposite direction, which may have a negative impact on your health.

The foods that can have the biggest positive effect on your microbiome are those containing beneficial bacteria (probiotics) and those containing indigestible fibres referred to as prebiotics.

Your microbiome is unique like a fingerprint

The term ‘microbiome’ refers to the collection of microbes that live in and on the body, of which there are around 100 trillion, the majority of which are found in the gut.  These bugs form a protective barrier defending the body from foreign invaders, which can be harmful to health.

The microbes in your gut include bacteria, which are essential for efficient digestion.  These bacteria also help to digest antioxidant polyphenols, synthesise vitamins such as B12, D, folic acid and thiamine, and produce short chain fatty acids that provide energy to the cells of your colon helping to maintain a strong gut barrier.  Gut bacteria have also been shown to play a role in immunity and new research is starting to explore the effect on the brain with early findings linking the diversity of bacteria in your gut to mental health and obesity (via the effect on hormones that control appetite).

Like a fingerprint, your microbiome is unique, and its composition is dictated by the world around you and within you.

Cultivation is key to a healthy microbiome

It’s yet unclear what constitutes a ‘healthy’ microbiome but one thing for sure is that it takes a bit of cultivation.  If your gut becomes overrun with bad bacteria then this can upset the balance of your microbiome, which may lead to symptoms such as bloating, excessive gas, abnormal bowels, bad breath and fatigue.

A poor diet is characterised by an over-consumption of sugar and bad fats, whilst lacking in nutritious foods such as vegetables and other wholefoods including beans, pulses and wholegrains.  This type of diet has been shown to promote the overgrowth of bad bacteria in the gut  (1, 2, 3).

Medication can also impact on gut bacteria as the overuse of non-steroidal anti-inflammatory drugs (NSAIDS) and antibiotics have the potential to destroy them, which can leave your gut vulnerable and increase the risk of infection.

What are prebiotics?

No doubt you will have heard about probiotics, which are friendly bacteria found in foods such as live yoghurt and supplements.  Other foods such as kimchi, kefir and miso also contain bacteria, which are beneficial to health.

The role of prebiotics is less well understood but they’re equally, if not more important than probiotics as these indigestible fibres help the bacteria in your gut to thrive.  Probiotic supplements have the potential to be very beneficial, especially if you need to re-balance the diversity of bacteria in your gut but the same is not necessarily true of prebiotics.

There are many food sources of prebiotics, which include inulin, lignin, oligosaccharides, mucilage gums, non-starch polysaccharides (pectin and beta glucans) and resistant starches.  Foods containing these prebiotics can easily be incorporated into your daily diet and many of which you may already be eating on a regular basis. You’re more likely to be eating prebiotic foods if your diet is healthy and contains plenty of plant-based foods.

Ten top prebiotic foods to include in your diet

There are quite a few prebiotic foods, but I have chosen the ones that are more commonly eaten and easily accessed from your local supermarket.

1.Jerusalem artichoke

This vegetable is now available in larger supermarkets and is in season between October and February.  Jerusalem artichokes contain 2g of fibre per 100g and 76% comes from inulin. You can also glean a good source of thiamine (healthy nervous system and releases energy from food) and iron (healthy immune system, red blood cell production and wards of tiredness) from Jerusalem artichokes.

These are not a commonly eaten vegetable as many people are unsure how to use them.  Jerusalem artichokes have a nutty flavour and can be used in the same way as potatoes in that they can be roasted and mashed, and also work well in soups.

2.Garlic

This vegetable is closely related to onions and leeks. Garlic can form the base of many home-cooked dishes alongside onions, which means it’s easy to add to your daily diet.  Around 11% of the fibre found in garlic comes from inulin and 6% from fructooligosaccharides, which add a slight sweetness to its flavour.

3.Onions

Onions are another food that can easily be included into your daily diet as it acts as a base for many home-cooked dishes.  Around 10% of the fibre found in onions comes from inulin and 6% from fructooligosaccharides.  Onions also contain a good source of vitamin C (protects cells, maintains healthy skin and helps with wound healing) and the flavonoid quercetin, which acts as an antioxidant in the body.

4.Leeks

This vegetable is similar to garlic and onions but less commonly used.  Around 16% of the fibre found in leeks is from inulin.  Leeks are also high in flavonoids, which support the body to respond to oxidative stress.  You can also glean a good source of vitamin A (healthy immune system, eyes, skin and mucosal linings such as the nose), vitamin C (protects cells, maintains healthy skin and helps with wound healing) and vitamin K (blood clotting and healthy bones) from leeks.

You can serve leeks as a side dish, incorporate into soups or a topping for pies.

5.Apples

There’s a lot of truth in the saying about an apple a day keeping the doctor away, and this includes the health of your gut.  Around 50% of the fibre found in apples is from pectin.  This prebiotic not only benefits the health of your microbiota but has been shown to help reduce cholesterol.  Apples are also high in polyphenol antioxidants.

As well as snacking on apples you can use them to make fruit puddings, add to savoury dishes and grate as a topping for yoghurt or soaked oats.

6.Asparagus

This vegetable is now available all year round with supermarkets importing it from countries such as Peru.  To savour the best tasting Asparagus and save on food miles, you’re better to wait until the British asparagus season, which occurs between April and May.   Asparagus is not as rich in prebiotics as other vegetables with only around 5% of the fibre coming from inulin. This vegetable also contains a good source of vitamin A (healthy immune system, eyes, skin and mucosal linings such as the nose), vitamin K (blood clotting and healthy bones) and folate (healthy red blood cells and protection against neural tube defects in unborn babies).

Asparagus is delicious served on its own with a big drizzle of olive oil or topped with a poached egg for breakfast.  You can also add asparagus to pasta dishes, risottos and soups.

7.Bananas

These fruits are one of the most commonly eaten in the UK and contain small amounts of inulin.  Unripe (green) bananas are high in resistant starch and feature as an ingredient in many Caribbean dishes. Bananas are also a good source of vitamin B6 (converts food into energy and helps to form haemoglobin in red blood cells).

Bananas can be eaten as a snack, baked and used in smoothies and fruit puddings.  For something different, try adding to curries.

8.Barley

This grain is not as commonly used as others such as rice but is actually hugely versatile once you know how to use it.  Barley contains around 8g of beta glucan per 100g, which is not only good for your gut but has been shown to help reduce cholesterol. Barley also contains the minerals magnesium (converts food into energy, promotes muscle relaxation and healthy bones) and selenium (protects cells and promotes a healthy immune system).

Barley can be used in place of rice to make risotto, added to soups or salads (cooked).

9.Potatoes

Potatoes are a starchy carbohydrate as are other foods such as grains.  Starches are long chains of glucose, which the body uses for energy.  When potatoes are cooked and then cooled, they develop resistant starches, which the body is unable to break down and as such behave as prebiotics.

10.Flaxseeds

These seeds are hugely healthy and a good source of prebiotics with 20-40% of their fibre coming from mucilage gums and 60-80% from cellulose and lignin.  Flaxseeds also contain phenolic antioxidants and are a useful source of protein. You can also glean a good source of minerals from flaxseed including magnesium (converts food into energy, promotes muscle relaxation and healthy bones), iron (healthy immune system, red blood cell production and wards of tiredness), calcium (healthy bones and teeth) and zinc (converts food into energy, involved in making new cells and enzymes and helps with wound healing).  Flaxseed are also rich in omega 3 and although the conversion to more usable forms of this fatty acid in the body is poor, it’s still a useful source, especially for people following a plant-based diet.

You can add seeds to any dish and also smoothies.

If you’re eating a healthy diet, then many of the foods included will naturally take care of your gut and including the foods listed above will be especially useful to promote the health of your microbiome.

The blokes guide to going vegan

The blokes guide to going vegan

The blokes guide to going vegan

Veganism is on the rise and research commissioned by the vegan society in 2016 showed that the number of vegans in the UK has increased by 360% over the last 10 years as a record number of people are choosing to avoid food derived from animals. Over 500,000 people aged 15 or over (more than one per cent of the population) have adopted this plant-based way of eating, making this one of the fasted growing lifestyle movements according to the Vegan Society.  Most vegans live in urban areas, with a quarter residing in London. A Mintel survey carried out in 2017 found that 11% of Britons had tried to follow a vegan diet at some point (1), whilst a previous report found that 33% of Brits had tried eating less meat to be healthier (2).

Vegan men

It wasn’t that long ago that Formula One superhero Lewis Hamilton said he was planning to go vegan full-time in an attempt to function at his healthiest and avoid damaging the planet.  “I stopped eating red meat two years ago”, he told the BBC.  Continuing, he said, “I think it’s the right direction and by letting people who are following me know, maybe that will encourage a couple of people to do the same thing”.  Other male vegan sports people include the footballers, Jermain Defoe and Dean Howell, and even heavyweights such as the British boxer David Hayes have made the switch to this plant-based way of eating. Hollywood celebrities have also followed suit with actors and musicians such as Jared Leto, Chris Martin, Woody Harrelson and Casey Affleck all reported to follow a vegan way of eating.

It still stands that more women are vegan but 37% are still made up of men (3) and the increase awareness of health and body weight amongst men may equally be driven these days by celebrity influence as it has always been amongst women. Recent research has suggested that even men who don’t like meat, find it upsets their digestion, or have been asked by a doctor to reduce consumption, still find it difficult to choose the vegetarian or vegan option when in public with other men.

Vegans in the UK

The growing trend towards veganism is reflected in the demand for meat-free food, which has increased by over 900% with this way of eating predicted by some sources to be one of the biggest food trends in 2018 (4,5).  Food industry insight provided by Foodable Labs reported that in 2018, fifty one percent of chefs in the US added vegan items to their menus.  The same report suggests that this rise is in part due to the influence of social media food and health bloggers as it showed a 79% increase in photos tagged as being vegan (6).

High street food outlets have recognised the increase and responded by offering more vegan options and certain branches of Pret are now solely offering vegetarian and vegan food. Dietary food labelling (including dairy and eggs) has also made it easier for vegans to choose their food when looking for something to eat on the High Street, although some restaurant options are still limited.

Benefits of veganism

Whilst some people choose to go vegan for ethical reasons (environmental damage from methane gases and deforestation, water scarcity and land degradation), others see this is a great way to improve their health and rightly so.  Research shows that non-meat eaters have healthier lifestyles compared to a typical omnivore diet. Plus, a well-balanced vegan diet is more likely to contain a greater quantity of fibre-rich wholegrain foods and pulses. It’s also been shown that vegans are more likely to exceed the daily recommended fruit and vegetable intake, which means gleaning a greater quantity of certain key vitamins and phytonutrients that help to protect the body from disease (7).

Studies also show associations between meat-free eating and a lower incidence of obesity (8), heart disease (9), high blood pressure (10), type 2 diabetes (11) and digestive disorders such as constipation (12).  Lifestyle habits do play a key role here and this doesn’t mean that following a vegan diet will definitely prevent you from developing these conditions.

Anecdotally, people who have gone vegan report better energy levels and overall wellness, but this could in part be to do with the fact that vegans have been shown to be healthier in general, more likely to exercise and less likely to smoke (13).

Men going vegan

Going vegan may pose challenges to certain men especially those programmed towards a ‘meat and two veg’ way of eating.  The vegan diet can be quite calorie restrictive, which means careful planning for men trying to maintain their body weight.  Men following a demanding fitness regime will also need to adjust their thinking towards how they source their increased requirement for protein. Certain nutrients are also more important for men’s health such as zinc, which is typically found in meat and seafood but easy to source from plant foods once you know which ones to include in your diet.

There’s absolutely no reason why anyone can’t glean everything they need on a vegan diet. The issue of nutrient sufficiency has nothing to do with the food and is more a case of people understanding what foods they should be including in their diet and how to incorporate them. Following a vegan diet does take a little more thought and planning, especially when you first start out, but once you begin to understand what this diet looks like in terms of food, then it’s no different to any other way of eating and the same basic principles of healthy eating apply.

What to expect and how to start

Firstly, you may find yourself feeling hungrier once you switch to a vegan diet, so you may need to be prepared to include a couple of snacks during the day and think about including certain more nutrient dense foods.  Switching to eating solely plants means you may be eating a larger volume of food but fewer calories so choosing the right foods to supply you with enough energy is key.

It’s essential to include foods such as nut butters, avocados, oils, nuts and seeds to your diet to maintain adequate energy levels. Try and make your meals up of a protein (see below), grain, and healthy fats (nut, seed, oil, tahini, avocado, nut or seed). Explore dressings and sauces to accompany your meals. If you do get hungry then fill the gap with dips (bean or veggie based), nuts, seeds, soya yoghurt with toppings, smoothies (try adding oats for extra protein) or breads (topped with nut butter, avocado or banana).

Secondly, there’s likely to be a greater burden on cooking and preparing meals so work out your go-to meals to make things a little easier.  This might be a tofu or vegan Quorn stir-fry or one pot dishes such as a bean-based chilli that can be batch cooked and frozen for future meals.

Thirdly, you may experience bloating and gas when you make the switch to eating more beans, pulses and other high fibre foods. This will pass as your body adapts to this way of eating.

You may want to ease yourself in gently to veganism by starting with eliminating animal flesh then after a few weeks cutting out eggs and dairy.

Nutrients you may want to focus on as you begin vegan eating

A balanced diet is bedrock to good nutrition but if you’re used to eating animal foods as the main component of your diet then you may want to consider how you source certain nutrients in your diet.

Protein

There’s a current obsession with protein and whilst the richest sources are found in animal foods, there’s no reason you can’t get everything you need from plants. The trick is to include a source of vegan protein with every meal.  The richest sources are tofu, beans, lentils, pulses and vegan Quorn but other sources include quinoa, nuts, nut butters and seeds.  You will also glean a little protein from foods such as breads, pasta and rice.  The idea of pairing proteins is outdated so just mix and match them across the day to get a good intake of all the amino acids that make up this macronutrient.

Zinc

Zinc is an important part of many enzymes and has a role to play in immunity, processing carbohydrates, fats and proteins from foods and wound healing. The recommended daily intake for zinc is set higher for men as it plays a key role in maintaining prostate health, testosterone levels and overall reproductive health.

There’s a suggestion that vegans may fall short of this mineral in their diet but there are plenty of plant foods containing zinc. There’s also the issue of absorption, which is thought to be less from plant sources so just being mindful to include plenty of zinc-rich foods in your diet such as spinach, nuts, seeds, cocoa powder, mushrooms, beans, breads and cereal products will do the trick.

Vitamin B12

Vitamin B12 is mostly found in foods of animal origin so vegans should try to include fortified products such as plant milks and breakfast cereals in the diet. Yeast extract is one of the few vegan-friendly natural sources of vitamin B12. Contrary to popular belief, spirulina and other algae products are not reliable sources of this vitamin

Iron

Low intakes of iron can lead to tiredness, fatigue and low mood as this mineral is required to make red blood cells that carry oxygen around the body. The type of iron found in meat is more easily absorbed by the body than plant-based sources, but you can increase the uptake by partnering them with a source of vitamin C such as serving fruit juice with your breakfast cereals or combining red peppers with pulses, beans and lentils. Avoiding tea with meals can also help maximise the absorption of iron from your food. Good sources include pulses, nuts, seeds, fortified breakfast cereals, tofu, tempeh, dark green leafy vegetables, dried fruit, molasses and dried spices.

Calcium

Calcium is essential for the good health of your bones and is also required for proper muscle and nerve function. Although dairy is often (falsely) thought to be one of the only sources of this mineral, you can glean more than enough from foods such as tofu, almonds, dark green leafy vegetables, sesame seeds, tahini and fortified plant-milks. Try eating two or three servings of calcium-rich foods on a daily basis.

Omega 3

Omega 3 fatty acids cannot be made in the body. The two most important are called eicosapentaenoic acid (EPA) and docosahexeanoic acid (DHA), which are predominantly found in oily fish.  Another type of Omega 3 called alphalinolenic acid (ALA) can be found in foods such as dark green leafy vegetables, quinoa, walnuts and chia seed oil.  This Omega 3 fatty acid is converted to EPA and DHA in the body, but the conversion rate is poor, so you may want to consider supplementing your diet with a vegan Omega 3 supplement (sourced from algae).

Store cupboard essentials for all vegans

  • Nuts
  • Seeds
  • Nut butters
  • Oils (extra virgin olive, rapeseed, sesame, chia)
  • Soy (tofu, miso, tempeh)
  • Fortified plant milks
  • Yeast extract
  • Dried spices
  • Cocoa powder
  • Quinoa
  • Canned beans, pulses and lentils
  • Tahini
  • Avocado
  • Hummus
  • Dried fruit
  • Wholegrains (oats, barley, brown rice, spelt)
  • Wholemeal pasta and breads
  • Vegan Quorn
  • Yeast extract
  • Fortified cereals

There’s no reason why anyone can’t get everything they need from a vegan diet.  Certain nutrients such as zinc are particularly important for men and they may also need to consider their overall energy and protein intake if they are trying to gain or maintain body weight alongside a heavy training regime.  They key is planning and understanding how to create quick and easy vegan meals to reduce the burden of cooking.  Supplements such as a multivitamin and mineral or omega 3 may be worth investing in as you begin the transition to vegan eating to insure you are getting everything your body needs.

Can the food you eat really ‘boost’ your immune system?

Can the food you eat really ‘boost’ your immune system?

Can you really ‘boost’ your immune system?

As much as I love basking in the sun, I actually love the Winter.  Cosy nights in, wrapping up in Winter woollies and the celebrations of Halloween, bonfire night, Christmas and New Year are all something to enjoy.  What I don’t relish is the prospect of Winter bugs and no matter how healthy you are, they always manage to creep their way in.

As the colder months approach, it becomes more important to eat and live well to support a healthy immune system, which helps to protect us against infections.  Even the best of us are up against it during the Winter and the challenges these months present can hamper good diet and lifestyle practices.  Comfort eating, and the influence of dark mornings and early evenings offer the perfect excuse to lapse on our healthy diet and exercise regimes.

The immunity ‘boost’ conundrum 

As Winter approaches, so comes the advice on how we can ‘boost’ our immune system to ward off infectious bugs.  The idea that you can ‘boost’ your immune system is a little misleading.  This concept conjures up a false expectation of ‘supercharging’ your immune system and in some way making it invincible to anything that attempts to challenge it. The reality is that immunity involves a system and not a single entity. There are many cells of the immune system that have to respond to many different types of microbes. Pinpointing the specific cells and defining to what degree they should be increased is hugely complex and a question that’s yet unanswered by science.

Given the intricacies of the immune response, the science behind the impact of diet and lifestyle on immunity is not definitive, but research is continuing to evolve and it’s clear that maintaining a healthy lifestyle is a key part of keeping your immune system strong and healthy.

Why do we need our immune system?

You couldn’t survive without an efficient immune system, which is made up of special cells, proteins, tissues and organs that defend the body against infectious organisms and other foreign invaders through a series of processes referred to as the immune response.

Foreign invaders in the body are referred to as antigens. These are toxins or other foreign substances that induce an immune response in the body, especially the production of antibodies. One example of an antigen is the common cold virus. What makes the immune system truly remarkable is that once it has encountered an antigen, antibodies are hard coded to fight this invader should it try to attack the body again.

Can the quality of your diet help to maintain a healthy immune system?

The simple answer is yes. Exactly how diet is linked to immunity is not fully understood but is an area of research that continues to evolve.  Scientists acknowledge that malnourished people are more vulnerable to infectious diseases, which helps to illustrate the importance of diet on immunity.

Maintaining a healthy balanced diet is key and there are many micronutrients (vitamins and minerals) required to maintain the normal functioning of the immune system.  If your diet is compromised in any way through dieting or illness for example, then you may not be eating enough food or the right quality of food that allows you to glean the nutrients required to support your immune system.

Findings from the National Diet and Nutrition Survey (NDNS) have shown that amongst certain groups of the population, intakes of certain vitamins and minerals that support immunity are lacking in the diet (1).  Vitamin D plays a key role in immunity and during the Winter months a significant percentage of people have been shown to have low levels of this nutrient, given the lack of sunshine, which is the main supplier.  Minerals such as selenium, iron and zinc also play an important role in immunity and have been shown to be lacking the diet of some people as have intakes of vitamin A.  This doesn’t necessarily mean your immune system will be compromised but that attention should be paid to eating the right foods to support healthy immunity.

Foods that can support your immune system

Diet is defined by food and not nutrients.  Eating a balanced diet consisting of whole foods such as vegetables, wholegrains, lean proteins and healthy fats, will support your immune system. However, for the purposes of this blog I’m going to lay out some of the foods that contain specific nutrients that support good immunity.

Vitamin A

Orange and green fruits and vegetables contain a pigment called beta-carotene, which is converted to vitamin A in the body. Vitamin A plays an important role in maintaining a healthy immune system (2).  This nutrient helps to maintain the integrity of the mucosal cells of the gastrointestinal tract, eye and respiratory system that function as a first line of defence to infection, forming a barrier between from the environment outside the body.  Vitamin A is also important for the normal function of immune cells and the production of antibodies that respond to infections.

Iron, selenium and zinc

All of these minerals are required for the production of antibodies, which are cells of the immune system that fight infection (3, 4, 5). Findings from the NDNS survey have shown that 27% of adult women and 54% of teenage girls do not get enough iron from their diet and partnered with menstrual blood loss, this puts them at particular risk of deficiency.  Selenium intakes are also low with 38% of adults being shown to have inadequate intakes. Zinc is also lacking the diet, with 8% of adults and 17% of teenagers shown to have inadequate intakes of this mineral (1).

You can maintain good intakes of iron by eating foods such as meat, poultry, oily fish and eggs.  Plant foods such as beans, pulses, dark green vegetables and dried spices are also a good source and you can increase the uptake of iron from these foods by partnering with foods rich in vitamin C.   Selenium is found in Brazil nuts, oily fish and wholegrain foods such as brown pasta, rice and bread. Levels of selenium do vary depending on where the food has been grown and the quality of the soil. Zinc is found in meat, shellfish, eggs, beans, pulses, wholegrains, nuts, seeds and cheese.

Vitamin C

This vitamin is the one people most associate with immunity and the common cold, which is backed up by some research suggesting its effectiveness at reducing the risk and length of infection (6).  Research has shown how several cells of the immune system accumulate vitamin C and requires this vitamin to perform their task, especially T cells and phagocytes.

Most people get more than enough vitamin C in their diet, but appetite can lesson if you do get ill, which may impact on your intake. You can keep your levels topped up by eating foods such as red peppers, citrus fruits, berries, broccoli and potatoes. Vitamin C is water soluble and easily destroyed so try not to overcook vegetables and avoid soaking before cooking.

Vitamin D

Vitamin D has been shown to play an important role in the immune system by increasing the antimicrobial effect of white blood cells that fight infection (7). Low levels of vitamin D can suppress the immune system, putting you at a greater risk of viral infections. Research involving more than 19,000 people found that those with the lowest levels of vitamin D were 36% more likely to develop a common cold than those with higher levels (8).

Findings from the NDNS have shown that 30-40% of all age groups are classed as being deficient in vitamin D due to the lack of sunshine (1). Public Health England recommends everyone takes a supplement providing 10mcg of vitamin D during the Autumn and Winter.

Gut bacteria also play a role

Over 70% of immune cells are located in the gut so it makes that a relationship exists between the two. We’re beginning to understand that it’s quality and not quantity that’s key to gut health and the diversity of microbes in your gut is referred to as your microbiome.

Probiotics are bacteria that have been shown to have a positive health benefit.  Well researched strains include those from the Lactobacillus and Bifidobacterium family.  Live yoghurt is the most well-known probiotic food and contains strains such as Lactobacillus Acidophilus and Lactobacillus Casei. Fermented foods such as kimchi, kefir and miso also contain strains of bacteria that can support good gut health.

Probiotic supplements offer a way of delivering large doses of specific bacteria to the gut and may be beneficial in the prevention of upper respiratory tract infections (URTI) such as the common cold (9). The effect of probiotics on the immune system has been widely researched and certain strains have been shown to promote the production of antibodies. The same strains have also been shown to stimulate the activity of immune cells such as natural killer cells and T-lymphocytes, which help regulate immune responses.   A Cochrane Review showed that probiotics were better than a placebo in reducing the incidence and duration of a URTI (10).

Choose a supplement that contains both Lactobacillus and Bifidobacterium strains in a dose of at least 10 billion bacteria per serving.

Mushrooms are interesting too

The overall quality of your diet is more beneficial than focusing on any single food or nutrient, but mushrooms do appear to be interesting when it comes to immunity.  Not only are they one of the few foods to contain a natural source of vitamin D, but they also contain beta-glucan polysaccharides that have been shown by some studies to modulate the immune system (11).  Chinese medicine has long considered mushrooms to be medicinal and especially varieties such as shiitake.

Immunity is a hugely complex system that involves many different cells that work together to fight foreign invaders in the body.  Your diet is known to have a role to play although exactly how is yet fully understood.  Eating a balanced diet is no doubt helpful and there are certain nutrients that play a key role in maintaining the proper function of your immune system. Diet shouldn’t be defined by nutrients as food is what matters but understanding the nutrients that support your immune system help to support the importance of a balanced diet made up of a wide variety of foods.

This had me thinking a little bit about how my view of breakfast and eating in general has changed over the years.  There was a time when I conformed to the view that breakfast was the most important meal of the day and that you should eat as soon as you get up.  However, as i’ve gotten a little older (heaven forbid I am nearly 40!! – cringe) my food taste and lifestyle has changed.  I’m no longer dashing to the gym at the crack of dawn as stressful deadlines and lack of organization skills have me up early, frantically typing to meet overdue deadlines and for some reason the last thing I feel like doing when I’m stressed or distracted is eating.  Coffee is the only thing that’s going to hit the spot at 6am.

Forget the old adage of eating breakfast like a king, lunch like a prince and supper like a pauper.  Who even came up with this anyway! I now firmly believe that eating should be more intuitive.  Not that you should throw regular meal times out of the window but I do think that we need to learn to listen to our body and eat when we genuinely feel hungry.

Understanding your own hunger and fullness is probably the best thing you can do to help maintain a healthy weight and work in sync with your body.  This doesn’t mean starving yourself because you’re too rushed in the morning to make breakfast or cant be bothered to cook, but satisfying the need for food when your body asks for it.

There’s a whole raft of information out there dictating when, how and what we should be eating, but understanding and listening to your own body is always going to be the best option.  There was a time when we had to hunt for our food and mealtimes were dictated by what you managed to forage or catch.  Although you cant draw comparisons as we have come a long way since then, eating for the sake of eating or at a set times during the day just doesn’t seem to make sense.

It’s really flippant to think this is an easy way to eat as there are wider issues around food that influence how and what people eat but learning to adopt basic mindfulness and intuitive eating skills can help.  Don’t be put off by the sound of these concepts as they really are just common sense.

Whilst a healthy balanced diet is key to good health, the idea of what this is has become very blurred as we have so much access to nutrition advice and media attention on the latest superfood or wonder diet.  Just getting back to basics about healthy eating and focusing your attention more on how you eat and not what you eat will help you to tune into your basic cycle of hunger and satiety.

Tips for mindful eating

Eat slowly

Eating is not a race.  Taking your time to eat and enjoy your food will help you to recognize when you’re full.  Chew your food slowly as this will help with digestion and give your body time to recognize that you are full.  Eating too quickly also leads to indigestion and bloating.  Many fast eaters have adopted these habits from childhood and they often come from large families so trying to educate your children on the idea of eating slowly may go some way in helping to prevent this habit from being passed on.

Switch off! 

Try and make food and eating the main attraction at the dinner table.  Turn the TV off and make dinner time an electronic-free zone.  This doesn’t mean forgoing the Saturday night take-away and movie but just making all other evening meal times about the food without distraction.

Savour the flavour

Eating slowly and savoring every mouthful of food allows you to appreciate the flavours and textures of food, which adds to the enjoyment of eating.  If you wolf down you meal in five minutes then it’s likely you won’t even notice what you’re eating and this can lead to a lack of appreciation making food and eating a mechanical process of eating to live rather than living to eat.

So after all that, what was my favorite breakfast?  Well it was chopped egg and avocado on toast that I actually ate at 11am when I finally felt hungry after a morning of deadlines and coffee.

Foods high in zinc

Foods high in zinc

Highest foods and greatest sources of zinc (download as a PDF Foods high in zinc)

Zinc is an essential mineral so you need to obtain it from the diet as your body cannot make it.  This mineral is involved in approximately 100 enzymatic reactions in the body and plays a role in immunity, protein synthesis, wound healing, DNA synthesis and cell division.  Zinc is also required for a proper sense of taste and smell as well as growth and development during pregnancy, childhood and adolescence.

This mineral is essential for men’s health.  Zinc plays a role in fertility by helping to improve the quality of sperm (1).  Research has shown that men with lower levels of seminal zinc had lower sperm counts as well as more abnormal sperm, which may be due to the protection of zinc against oxidative damage.

Zinc may also help to protect the health of the prostate.  Men with low levels of zinc in their diet tend to have higher chances of developing and enlarged prostate, which is known as benign prostate hyperplasia or BHP (2).

Zinc has long been associated with immunity and the common cold and some evidence points towards the benefits of this mineral in lessoning the symptoms by way of zinc lozenges (3).  Zinc also not only increases the production of white blood cells that fight infection, but also helps them fight more aggressively. It also increases killer cells that fight against cancer and helps white cells release more antibodies.  Zinc increases the number of infection-fighting T-cells, especially in elderly people who are often deficient in zinc and whose immune system may weaken with age (4).

Skin and hair health may also benefit from gleaning enough zinc from your diet.  Zinc plays an important role in overall skin health, and it may also treat eczema, psoriasis, dandruff, burns and boils (5).  This essential mineral also helps skin wounds heal faster.  Low intake of zinc has also been associated with hair loss (6)

Like many nutrients, zinc also acts as an antioxidant in the body.  Antioxidants help to reduce the damage done by excess free radicals that can increase cell aging and build up as a result of a poor diet, lifestyle and environmental factors. Antioxidants also play a role in reducing inflammation in the body.  Prolonged inflammation is thought to be at the root of many serious health conditions such as heart disease and cancer.

 

How much do you need?

UK Adult men require 9.5mg per day

UK Adult women require 7mg per day

 

Average intakes in the UK

Women consume more zinc than men

Most men and women have intakes above 100% of the RNI for zinc

9% of adult men have very low intakes of zinc

10% of teenage boys have very low intakes of zinc

 

Groups most at risk of deficiency  

The bioavailability of zinc from vegetarian diets is lower than from non-vegetarian diets because vegetarians do not eat meat, which is high in bioavailable zinc. Vegetarians and vegans also typically eat high levels of legumes and whole grains, which contain phytates that bind zinc and can inhibit its absorption.

Vegetarians can sometimes require more zinc than non-vegetarians. Certain food preparation techniques can help to reduce the binding of zinc by phytates and increase its bioavailability such as soaking beans, grains, and seeds in water for several hours before cooking them and allowing them to sit after soaking until sprouts form. Vegetarians and vegans can also increase their zinc intake by consuming more leavened grain products (such as bread) than unleavened products (such as crackers) because leavening partially breaks down the phytates; thus, the body absorbs more zinc from leavened grains than unleavened grains.

Alcoholics can have low levels of zinc because alcohol decreases intestinal absorption and increases urinary excretion of zinc.  Alcoholism can also affect food intake, which can limit the amount of zinc consumed.

Be aware that high intakes of zinc intakes can inhibit copper absorption, sometimes producing copper deficiency and associated anemia so be wary of supplement containing very high doses of this mineral.

 

How to increase your intake of zinc 

  • Add seeds as a topping to salads, cereals and porridge
  • Include plenty of dried herbs and spices to your meals
  • Include shellfish in your diet, which can be used to make salads, stews and stir-fry’s
  • Include plenty of pulses and lentils in your diet, which can be added to salads, stews, casseroles, soups or made into dips
  • Cocoa powder is high in zinc so the occasional treat of high cocoa dark chocolate is a good source of try making a cup of cocoa or homemade nut milks flavoured with this ancient ingredient
  • Try switching to wholegrains such as breads, rice and pseudo grains such as quinoa
  • Oats are high in zinc and make great breakfasts or toppings for sweet dishes such as crumbles and even savoury toppings
  • Nuts and seeds are high in zinc so try making your own healthy granola or flapjacks
  • Go veggie a few times each week and swap meat for tofu or Quorn
  • Eggs are the breakfast of champions and also make a great snack when boiled (try serving with smoked paprika, celery salt or tabasco sauce)
  • Don’t skip breakfast! Even a small bowl of your favourite wholegrain cereal can add a useful source of zinc to the diet. You can also use cereals as savoury topping

Linguini with crab and chilli

Linguini with crab and chilli

A quick supper idea that reaps the benefits of shellfish

 

Although I regularly preach about the benefits of choosing unprocessed carbohydrates, sometimes nothing quite beats a large bowl of white pasta, especially when teamed with one of my favourite ingredients, crab.  I’ve never been against including carbohydrates in the diet and as an active person I find them invaluable.  I also love food and enjoy eating a wide variety of different foods in my diet, which is a way of eating I fully endorse and a good strategy for gleaning everything your body requires.

White flour in the UK is actually fortified with nutrients such as iron, calcium and B vitamins so whilst they lack the fibre, which is the main benefit of choosing unprocessed varieties, they still offer something nutritious to the diet. White carbohydrates do effect blood sugar levels more aggressively than their high-fibre counterparts, but this effect is counteracted by teaming them up with a source of fat, protein and other high-fibre foods such as vegetables.

This dish is one of my favorites as I love crab.  Shellfish such as crab are a lean source of protein and rich in vitamin B12 and zinc, which makes them a great food choice for men as zinc plays a key role in the male reproductive system.  This dish is also a very good source of iron, which is required to maintain healthy red blood cell production and also a rich source of magnesium and potassium that are both associated with good heart health.

Crab is not an ingredient that makes a regular appearance in most peoples weekly shop but is readily available in most supermarkets as well as your local fishmonger.  If you can’t find crab then this dish also works really well with prawns.
