Your Child’s Health Checklist

It can be difficult getting your kid’s into a back to school mind-set after the summer holidays, so why not prepare them in advance by boosting the mental and physical performance of your little one with a diet packed with vitamins and nutrients and regular exercise over the next 6 weeks.

Follow our checklist to help you give your child a head start of their next school year:

  • Its summer so make sure your little one gets a small dose of vitamin D courtesy of the sun (all fair-skinned people need is a few minutes of sun on their hands, arms and face every day). However, if the sun isn’t shining, then be sure to include it in their diet through fatty fish, like salmon and tuna, and egg yolks.
  • Children need calcium to make strong bones, but they can only deposit this calcium until their early 20s. Make sure yours get their three servings a day – a serve is a 250ml glass of milk, a 200g tub of yoghurt or two slice of cheese (40g).
  • Poor concentration, failing memory, hyperactivity and mood swings can also be an indication of omega 3 (EPA and DHA) deficiency. Our brains need these long-chain omega-3 fatty acids for brain structure and function. Try supplementing your child’s diet with a kid friendly omega 3 supplement.
  • Iodine deficiency is the world’s most prevalent, yet preventable cause of brain damage and lower IQs according to the World Health Organisation (WHO). Make sure your child gets between 90mcg and 120mcg a day. Yoghurt, cow’s milk, eggs, mozzarella cheese and strawberries are excellent sources of iodine.
  • Magnesium de¬ficiency has been linked with learning difficulties, hyperactivity and insomnia and it’s believed three quarters of children don’t consume enough of this mineral. A half-cup of cooked frozen spinach provides 75mg. You should aim to include 130mg a day.

More Top Tips

  • Exercise, chill time, and regular, nourishing meals and snacks enhance concentration by banishing energy wobbles.
  • Friendly foods include fresh fish, vegetables, pulses, whole grain carbohydrates, nuts, and seeds. Water helps too!
  • Cerebral zappers include sugar, caffeine, soft drinks, junk food, processed foods, excess salt, meat and dairy, and refined or hydrogenated fats and oils (be sure to read the labels!).
  • We all need sleep to function properly, but while adults need eight hours, children need a minimum of 10 hours shut-eye every night. Encourage regular exercise during the day, and participation in age appropriate extracurricular activities after school which will both result in adequate sleep at night.
  • Make sure your child is protected against colds with a drink of Manuka Honey and fresh lemon juice in hot water. Echinacea will also support the immune system, prevent infections, and minimise the risk of bronchitis and sinusitis.

Fertility and Pregnancy Support – From Conception to Birth

Conception

Making the decision to have children may sometimes be easier than getting pregnant. There are many potential causes of infertility, with fertility problems affecting either the man or the woman. Common causes of infertility in women include lack of regular ovulation and endometriosis, and in men the most common cause is poor quality of semen.

Optimum nutrition is absolutely vital for conception and food supplements are useful where an additional intake of specific nutrients is required. AnteNatal Forte provides a combination of nutrients designed to support a woman throughout conception and pregnancy, especially during the first trimester. It is free from vitamin A for those wishing to avoid it, but supplies beta carotene which the body can convert to vitamin A as required. It contains zinc to support normal fertility and reproduction, vitamin B6 which contributes to the regulation of hormonal activity, and folic acid which contributes to normal maternal tissue growth during pregnancy.

ASC Plus provides a combination of synergistic nutrients to support male fertility, including L-arginine, vitamin E, L-taurine, L-Carnitine, zinc and selenium. Zinc supports normal fertility and reproduction, whilst selenium contributes to normal spermatogenesis – the process in which sperm is produced.

Pregnancy

Pregnancy and omega-3 – a clever combination for baby’s brain

Assuming normal fertility, the next challenge is pregnancy, where there are significant biological changes which occur including an increased demand for nutrients such as vitamin D, B12, folic acid, iron, calcium, magnesium and zinc.

A healthy baby begins with a healthy mum – eating a well-balanced and varied diet that includes fresh fruit and vegetables, wholegrains, pulses and fish will help to provide the nutrients that you and your baby need. Where an additional intake of nutrients is required, a specific pregnancy supplement can be useful. Pregnancy & Lactation Formula is designed to offer comprehensive nutritional support to women during pregnancy and breastfeeding. It includes folic acid at recommended levels along with vitamin B12, iron, zinc and vitamin A at a level considered safe in pregnancy. It’s also important to avoid harmful habits such as smoking and excessive caffeine or alcohol consumption to help reduce the risk of any pregnancy complications.

Pregnancy and omega-3 – a clever combination for baby’s brain…

NHS recommendations suggest that eating fish during pregnancy is beneficial to your health as well as the development of your baby. However it is suggested that you should avoid consuming more than 2 portions of oily fish per week as it may contain pollutants. Omega-3 fatty acids provide EPA and DHA – maternal intake of DHA has been shown to contribute to normal brain and eye development of the foetus and breastfed infants, making its intake rather important.

Mega EPA is a naturally concentrated fish oil of outstanding quality and high potency. Each capsule provides omega-3 fatty acids in a natural triglyceride form, perfect for everyday use. It is of outstanding purity and free from detectable contaminants, so can safely be used during pregnancy and whilst breastfeeding.

Arrival of the newborn

Some expectant mothers choose to take probiotics throughout their pregnancy, as well as give them to their newborn baby. AnteNatal BioFlora is a clinically proven probiotic for pregnant women containing LAB4B – a specific and clinically proven blend of probiotic bacteria. It has been designed to be used particularly during the last trimester of pregnancy, and provides a guaranteed 10 billion live bacteria per daily intake. Baby BioFlora is an easy-to-use powder and contains the same specialist blend of LAB4B probiotics as AnteNatal BioFlora with the addition of G.O.S (galactooligosaccharide) which is found in high concentrations within breast milk. It is suitable to be given to babies from birth and can be used to help establish intestinal microflora in newborns up to 12 months.

Plant-sourced omega-3s

Fish is the richest food source of omega 3, with mackeral, trout and herring being the strongest source
Fish is the richest food source of omega 3, with mackerel, trout and herring being the strongest source

By now it is well known that omega-3 fatty acids are beneficial for health; however, it is important to know that not all omega-3s are the same. The various chemical structures of different types of omega-3 fatty acids exert varying effects on health.

The science of fatty acids

So a bit about the science: ‘short-chain’ fatty acids are those found in plant oils and as the name suggests, they are made up of a smaller number of carbon atoms, therefore making the chain short in length. ‘Long-chain’ fatty acids, such as omega-3 EPA and DHA found in fish, are those with more carbon atoms, and are longer in length. The longer chain fatty acids are those that produce the anti-inflammatory effects in the body by producing hormone-like substances called eicosanoids.

Vegetarian plant source

If you are vegetarian or vegan, you may be wondering how you can achieve this anti-inflammatory effect without eating fish. Fortunately, the body is adept at converting fatty acids (to a certain extent), so that when we eat ‘short-chain’ fatty acids such as echium seed oil, the body can metabolise these fats into the same chemical structure as the ‘long-chain’ omega-3 EPA found in fish. In this process, only a certain amount of short-chain fatty acids are converted to long-chain fatty acids, depending on both the type of fat consumed and the presence of other vitamins and minerals which are required for enzymes to work properly.

Echium seed oil

Echium seed oil is one of the finest oils of choice for vegetarians, as it naturally contains an optimal balance of omegas 3, 6 and 9. Unique to echium seed oil is its rich source of the specific omega-3 fatty acid SDA, which is the direct precursor to omega-3 EPA, meaning that it is very easily converted to EPA in the body, with usually around 25-30% conversion. This makes echium seed oil one of the best plant-sourced oils to consume for reducing inflammation; it may therefore help to reduce symptoms for conditions such as arthritis and inflammatory skin disorders. EPA is also required for synthesising neurotransmitters such as serotonin and dopamine, so echium seed oil may help to enhance mood.

Echium seed oil also contains the omega-6 fatty acid GLA, which is great for skin health and hormone balancing. Omega-9 oleic acid, also in echium seed oil, is high in a Mediterranean-type diet and is otherwise found in olive oil. Echium seed oil contains twice as much omega-3 compared to its omega-6 and omega-9 content, therefore is considered to be anti-inflammatory, and can help to balance the omega-3 to omega-6 ratio.

Linseed oil

Linseeds are often the omega-3 of choice for vegetarians as they are the richest source of the short-chain fatty ALA, although in reality only around 5-8% of this is converted to EPA, so for vegetarians, you would have to consume huge amounts of linseed oil to obtain the anti-inflammatory effects. It is important to stress that it’s healthy to continue to include these fatty acids in your diet as the fibre and vitamins & minerals found in linseeds are particularly beneficial to health, so keep up with the ground linseeds sprinkled over your breakfast, but don’t rely on the oil to reduce inflammation in the body.

Algae oil

Algae oil is another interesting oil of choice for vegetarians, as algae are a direct source of food for fish. Algae oil contains the long-chain omega-3 DHA, and a very small amount of EPA. The high DHA to EPA ratio does not give great support for controlling inflammation in the body, as it is EPA required at the higher dose, and EPA and DHA also compete for enzymes in the body. High DHA from algae is, however, beneficial during pregnancy, as DHA is required for making the brain structure of an unborn foetus.

Other plant-source oils

Omega-3 can also be found in other plant oils such as hemp seed oil, chia seed oil and pumpkin seed oil; however, all of these oils contain the short-chain fatty acid ALA, which is therefore not converted as readily as the fatty acid SDA found in echium seed oil. Hemp, chia and pumpkin oil are also much higher in omega-6 fatty acids compared to omega 3, so the ratio is not as anti- inflammatory in the body.

For vegetarians and vegans, choosing an oil high in omega-3 SDA such as echium seed oil is likely to do wonders for your health, so consider this an option over other oils which may be more difficult to convert to EPA in the body.

Vegans respond well to algae-based omega-3 supplements

Omega-3 levels in vegans are low and can successfully be addressed with algae-based omega-3 supplements according to a new study (1).

The study of 165 vegans found that their omega-3 index was just 3.7%, which is too low and indicates a raised risk for heart disease.

The ‘omega-3 index’ is a measure of omega-3 in cell membranes. A level below 4% represents a high risk of developing heart disease, while a level of above 8% is considered low risk (2).

A selection of the group were supplemented with 243mg of algae-derived EPA + DHA each day for four months. During this time, the omega-3 index of this group rose from 3.1% to 4.8%. The researchers concluded that “low dose supplementation with algae-sourced DHA and EPA may mitigate the potential adverse effects of deficiency in this population.”

The recommended intake of omega-3 is 450mg per day, according to the government’s Scientific Advisory Committee on Nutrition. Unfortunately in the UK the average intake is around half this amount, at just 250mg per day.

Incidentally, the level of omega-3 found in vegans in this study is actually no lower than that found in omnivores. This population-wide deficiency in omega-3 is a concern, especially considering the range of health benefits linked with this particular fat. In addition to its cardio-protective benefits, omega-3 has been linked with eye health, brain health and a healthy immune system.

An important consideration for those wanting to boost their omega-3 intake is the danger of toxins. The richest source of omega-3 is oily fish, but unfortunately these fish have a tendency to accumulate mercury and other toxic pollutants such as dioxins and PCBs. For this reason, women who are pregnant or breastfeeding are advised not to eat more than two servings of oily fish each week.

Omega-3 levels in vegans are low and can successfully be addressed with algae-based omega-3

Because mercury tends to accumulate in protein rather than fat, fish oil supplements can provide a ‘cleaner’ way to obtain your daily omega-3. For this reason, supplements do not pose the same concerns over mercury ingestion as oily fish in the diet.

Dioxins and PCBs are rather a different story. These contaminants tend to accumulate in fat, and so are present not only in oily fish, but also in poor quality fish oil and algae-based supplements. For this reason it is essential to choose a very good-quality supplement. For example, Eskimo-3 was found to contain the lowest levels of dioxins and PCBs in independent testing. Products from Biocare and Higher Nature also performed well. To illustrate the variability in quality, the same study found that the level of contaminants in Boots Cod Liver Oil was more than 50 times greater than that found in Eskimo-3. Dioxin levels in Tesco’s Cod Liver Oil were also well above the maximum limit for fish oils intended for human consumption (3).

Good quality vegan supplements represent a clean way of supporting omega-3 levels, as algae can quite easily be grown in controlled, unpolluted conditions. This is the case for supplements such as opti3, which is made from algae grown in a fully-controlled pharmaceutical facility. This particular supplement is therefore recommended for pregnant and breastfeeding women owing to its clean profile.

In light of the above study results, vegans wanting to ensure healthy levels of omega-3 would certainly do well to consider such a supplement. Even those of us who aren’t vegan or vegetarian might consider algae-based supplements as a sustainable and pure source of omega-3.

Top Nutrients for Heart Health

Collectively, conditions affecting the heart are the UK’s biggest killer. Almost 2.3 million people live with coronary heart disease (CHD), leading to annual NHS healthcare costs of almost £2 billion. Key risk factors for heart disease affect large proportions of the adult population – one third of adults have high blood pressure while 60% have sub-optimal blood cholesterol levels. Despite these alarming figures, many risk factors are within our control and making simple changes to our diet and lifestyle can have a dramatic impact on our health. As we mark National Heart month we turn our attention to key nutrients and nutrition supplements that play a strong role in maintaining a heart-healthy lifestyle.

ALA Omega-3

Alpha-linolenic acid (ALA) is a type of omega-3 essential fatty acid (or ‘good’ polyunsaturated fat) that has been shown over years of research to help maintain normal cholesterol levels. Although cholesterol is a vital resource in the body, helping to carry out a number of important functions such as repairing blood vessels, creating hormones, production of vitamin D, and helping to transport vitamins A, D, E & K, it can become a risk when levels of LDL ‘bad’ cholesterol become too high. This can trigger a build-up of plaque in the arteries, which can eventually

lead to heart attacks and strokes.

Dual cholesterol protection

Despite popular belief, only 20% of the cholesterol in our body comes from our diet whereas the majority, the remaining 80%, is produced by our own cells, mainly in the liver. ALA directly reduces production of cholesterol in the liver at its source, which is a highly effective way of normalising cholesterol levels.

ALA is also well known for reducing inflammation in the body, which helps to slow down plaque build-up in the arteries. Taking ALA daily is a great way to favourably balance the ratio of ‘good’ to ‘bad’ fats consumed in the diet.

Ubiquinol CoQ10

Coenzyme Q10 (CoQ10) is a naturally occurring enzyme with a multitude of roles in the cardiovascular system. CoQ10 acts within our cells in the mitochondria, the body’s energy ‘powerhouse’. Maintaining healthy CoQ10 levels fuels the mitochondria and supports the high energy requirements of our organs, particularly the heart. In addition to energy production, CoQ10 plays a vital role in oxygen utilisation to further support the functioning of heart muscle cells and maintain good circulatory health. CoQ10 also helps to lower blood pressure and is recognised as an effective cholesterol lowering ‘agent’.

Research studies show that people with cardiovascular problems often have low levels of CoQ10. Risk of deficiency is even higher with patients taking statins to lower cholesterol, since not only are they likely to have low levels of CoQ10 but statins also block natural ubiquinol synthesis in the body.

Ubiquinol versus Ubiquinone

There are two types of CoQ10 used in supplements: ubiquinone and ubiquinol. Ubiquinol is ‘body-ready’, which means the body doesn’t have to convert it into a usable form – a therapeutic advantage over ubiquinone. As an antioxidant, ubiquinol also offers protection against arterial plaque, thereby reducing heart attack risk and safeguarding heart muscle cells from free radical damage. Uniquely, ubiquinol also regenerates other beneficial antioxidants such as vitamins C and E.

Ubiquinone versus ubiquinol is just half the battle with CoQ10; addressing bioavailability is a further challenge, since therapeutic outcomes are achieved by raising blood plasma levels. Most ubiquinol supplements are oil-based, which means that large ubiquinol particles struggle to pass through the gut’s water layer barrier and are poorly absorbed. A special patented delivery system called VESIsorb®, utilised by CoQ10 manufacturer Igennus, optimises absorption by converting ubiquinol into water-soluble particles, ‘pre-digesting’ it so ubiquinol is effectively fast-tracked through the digestive system. VESIsorb delivers ubiquinol into the blood stream 2 times faster than standard oil-based forms, increasing tissue distribution throughout the body to achieve significantly higher blood concentrations that remain at therapeutic levels for up to 6 times longer.

Live cultures

Three specific live cultures L. plantarum CECT 7527, 7528 and 7529, help break down bile salts, which are made from cholesterol, therefore allowing its removal from the body. These friendly bacteria also metabolise dietary cholesterol in the gut, therefore reducing its absorption into the bloodstream. The AB-LIFE strains also produce a beneficial short-chain fatty acid known as propionic acid, which signals the liver to produce less cholesterol and also has an anti-inflammatory effect.

Top heart health supplements

A new and unique formula from OptiBac Probiotics is the first of its kind formulated for heart health. For your cholesterol is a pioneering, well researched multi-targeted natural supplement that combines unique live cultures with omega-3 ALA from cold-pressed virgin flaxseed oil – offering a multitude of benefits for managing healthy cholesterol levels.

Since not all live cultures are the same, OptiBac Probiotics focuses on specific strains of natural bacteria that have been clinically tested and proven to survive stomach acidity, bile salts and digestive enzymes in order to find the best live cultures for the job.

VESIsorb® Ubiquinol-QH from Igennus provides 100 mg of fast-acting body-ready ubiquinol CoQ10 for optimal therapeutic benefits. Taken daily, this advanced supplement offers comprehensive cardiovascular support, providing potent antioxidant activity and maximal energy production.

Movember: Eat to Beat Prostate Cancer

Thousands of men across the UK are sprouting moustaches this month, in aid of Movember, an annual event aimed at raising awareness of men’s health issues.

Men are less likely to visit their GP when ill, less likely to access disease screening services and less likely to seek support with healthy-living initiatives such as stop smoking schemes. Consequently, serious diseases such as cancer and diabetes tend to be diagnosed later in men than in women. This is why raising awareness and encouraging a dialogue about men’s health issues is particularly important.

Prostate cancer is a particular focus for the Movember campaign because this disease can be difficult to spot in its early stages. In addition, one in eight men in the UK will develop prostate cancer, making this the most common type of cancer in men.

Lamberts_fish_oil
For those who do not eat oily fish regularly, it may be prudent to supplement with a good quality fish oil supplement.

The prostate, found only in men, is located below the bladder. Its function is to produce fluid to nourish and protect semen. The prostate often enlarges as men get older, causing troublesome symptoms for some men.

Symptoms of all prostate problems include:

  • needing to urinate often, especially at night
  • difficulty starting to urinate
  • straining to urinate or taking a long time to finish
  • pain when urinating or during sex

There is plenty of research suggesting that dietary changes help reduce the risk of developing prostate cancer.

Studies have found that men with a higher level of omega-3 fatty acids in their body had a reduced risk of prostate cancer. Omega-3 is present in oily fish and in smaller amounts in flaxseed and some plant foods. One study of more than 6000 men found that men who regularly ate oily fish such as salmon, sardines and mackerel had a reduced risk of developing this condition. The men who ate no fish were more than twice as likely to develop prostate cancer as those who ate moderate to high amounts. For those who do not eat oily fish regularly, it may be prudent to supplement with a good quality fish oil supplement.

High dairy consumption is linked to an increase risk of prostate cancer as evidenced by a number of studies in this area. One study found that men who consume two and a half serving of dairy each day have a 40 per cent increase in prostate cancer risk (2). This is probably because eating diary raises levels of Insulin like Growth-like Growth Factor which can promote growth of cancer cells. A recent meta analysis reports that soya consumption, on the other hand, is linked with a reduced risk of prostate cancer (3), and so replacing cow’s milk with soya milk is likely to be a helpful measure.

Cancer is known to be triggered by damaging molecules known as free radicals. Antioxidants ‘mop up’ these free radicals and so it seems sensible to ensure that the diet is abundant in rich sources of these nutrients. Men who eat four servings of vegetables a day have a 35 per cent reduced risk of prostate cancer compared to those who eat just two servings. In addition, vegetarian men have a lower risk of developing prostate cancer than meat eaters.

Two supplements that have been widely studied in relation to prostate cancer risk are selenium and saw palmetto. Selenium has antioxidant properties and aids DNA repair, and a recent meta-analysis showed a potential inverse association between toenail, serum, and plasma selenium levels and prostate cancer risk (4). Selenium is present in most multi-vitamin and mineral supplements. Alternatively, just two Brazil nuts each day will fulfil your daily requirement of this mineral.

Saw palmetto is often used for its protective benefits. This nutrient is anti-inflammatory and also helps to prevent the conversion of testosterone to DHT, an agent that promotes prostate cancer (5). Large studies have found saw palmetto supplementation to be beneficial in benign prostatic hyperplasia (BHP) or non-cancerous enlargement of the prostate (6). While more research need to be done in this area, saw palmetto appears to be safe to supplement and has no known drug interactions, making it a worthy of consideration in supporting prostate health.

Fish Oil Supplements

We are often told that we should eat oily fish or take a fish oil supplement, but why? When? Which one do you choose?

Why do you need fish oil?

Although maligned by the weight loss industry, dietary fats exist for a reason. They are present in plant and animal tissue because they perform vital functions for those organisms and, when we consume them, they do the same for us. The body needs to ingest or synthesise a ready supply to maintain health. Some lipids are even essential because they cannot be manufactured by the body and must be obtained through diet. There are many different forms of lipids, one of the most crucial subsets are the essential fatty acids (EFAs), omega-3 and omega-6.

Some anthropologists believe consumption of omega-3 fats lead to profound changes in the human brain. We probably evolved on a 1:1 ratio of omega 3:6 in our diets (1). Post agricultural and industrial revolutions, this has dramatically switched in favour of omega-6 and is now closer to 16:1. Balancing omega-3 and 6 fats is crucial for the management of many chronic diseases. Oils from cold water fish such as salmon, sardines, trout and mackerel have been the subject of thousands of research papers, showing efficacy for a number of conditions. They provide a rich source of the active omega-3 fats, eicosapentanoic acid (EPA) and docosahexaenoic acid (DHA). Vegetarian sources of omega-3 require further conversion in order to metabolise EPA and DHA.

The most obvious way to tackle the shortfall in dietary omega-3 is to consume more oily fish. Individual taste is often a barrier. Furthermore, the beneficial long chain omega-3 fats can be damaged by cooking and the larger fish such as salmon can contain high levels of heavy metals and other contaminants. Therefore fish oil supplementation presents a practical way to increase omega-3 intake, but not all fish oil products are created equally.

When choosing a product it is important to be sure that it has been produced with due regard to environmental impact, has an exemplary quality profile and is effective.

How much do you need?
The omega-3 essential fats, EPA and DHA, are mostly found in oily fish such as sardines and anchovies

To maintain healthy levels of essential fats, the government recommends that we all eat at least two portions of oily fish each week but this can be difficult to achieve through diet alone, especially if you don’t like to eat fish! A good quality fish oil supplement can be a great option to ensure levels are high enough to maintain good health.

How do you know if a supplement is good quality?

Here are a few tips when looking for a good quality fish oil supplement:

  • Look for a fish oil supplement that is produced from small fish such as anchovies and sardines as the levels of essential fats within these fish are naturally more concentrated. You will therefore get better quality oil.
  • Look at where the fish are sourced. Small fish sourced from areas such as the clear pacific waters will drastically minimise the level of pollutants. This will mean you will get cleaner, more pure oil.
  • Look for oil that has had minimal processing. Fatty acids are delicate and can become damaged when put through aggressive production methods. If minimal heat and chemicals are used, the oil will be closer to its natural form.
  • Look for variety. If fish oil is pure and clean, then it can be made into capsules and liquids that have very little fishy aftertaste. Some fish oils can even be mixed with fruit bases so that adults and children can enjoy taking a daily supplement.

Five Ways to Fight Inflammation

Inflammation is a natural process and is part of our immune system, helping to heal injury and protect us from infection. Unfortunately inflammation can sometimes get out of control. Modern living appears to encourage chronic low-grade inflammation. For example, when the body is under stress, from poor diet, excess weight, pollution or even simply through ageing, inflammation can be triggered.

Once inflammation is triggered, it can become a chronic problem. Professor William Meggs, chief of toxicology at East Carolina University explains: “Once inflammation begins, it sets off a series of physiologic reactions that cause additional inflammation and the body’s reactions become more and more difficult to turn off” (1).

Conditions such as arthritis, heart disease, periodontal disease, premature ageing, inflammatory skin conditions and allergic reactions are all examples of chronic low grade inflammation. Achieving optimal health means taking measures to control your inflammation risk. Below are some simple dietary guidelines for controlling and reducing levels of inflammation.

1. Aim for 9 servings of fruit and vegetables daily.
Phytochemicals in fruit and vegetables have both anti-inflammatory and antiallergic agents. Studies have found that increased fruit and vegetable intake lowers markers of inflammation and oxidative stress (2). Aim each week to eat at least one of these top inflammation-fighting foods from each of the following categories:

fruit
9 servings of fruit and vegetables can help aid inflammation

Cruciferous vegetables:
Bok choy, broccoli, brussels sprouts, cabbage, cauliflower, kale, watercress
Leafy green vegetables:
Collards, chard, lettuce, mustard greens, spinach
Legumes:
Black beans, chickpeas, kidney beans, navy beans, peas, pinto beans, soybeans
Berries:
Blackberries, blueberries, raspberries, strawberries
Beta-carotene-rich foods:
Apricots, cantaloupe, carrots, mango, pumpkin, sweet potato

2. Increase levels of omega 3.
The best sources of omega-3 are oily fish such as mackerel, salmon, tuna, sturgeon, anchovy, herring, trout, sardines and mullet. Better still, choose those with lower levels of mercury contamination such as sardines, salmon and North Atlantic mackerel.  Fish oil suppresses anti-inflammatory cytokines, reducing inflammation (3). Alternatively, fish oil supplements can be added to your diet. If you are vegetarian, you should include a tablespoon of good quality flaxseed oil daily.

3. Decrease levels of omega 6.
While omega-3 has anti-inflammatory effects, omega-6 is usually pro-inflammatory. A good balance between the two is essential for optimal health. Unfortunately the ratio of omega 6 to omega 3 in the modern diet tends to be too high. In the UK, our ratio of omega 6 to 3 is around 20:1 whereas the ideal ratio of omega 6 to 3 is thought to be nearer to 4:1 (4). Limiting processed and fried foods containing vegetable oils and reducing foods high in arachidonic acid, such as red meat, may help to reduce levels of undesirable inflammatory markers such as C-reactive protein (CRP).

4. Add olive oil to your diet.
Olive oil improves cholesterol levels and contains powerful antioxidants. This oil plays a huge part in the Mediterranean diet, which is linked to longer life expectancy and lower rates of cardiovascular disease. A recent study found that adding just 1.5 tablespoons of olive oil daily for one week reduced levels of LDL cholesterol (5). Try using olive oil as a salad dressing, or substituting the oil for your usual margarine.

5. Watch your AGE.
Highly processed foods and meats cooked at high temperatures are likely to have high levels of Advanced Glycation End products. AGE products increase inflammation, and are caused by prolonged processing such as heating and sterilising. Fortunately there are several ways to reduce AGE products. Cooking using a lower temperature, using moist heat, and adding acidic ingredients such as lemon juice or vinegar will help (6). If you are making a stir-fry, the best way to reduce AGE products is to include plenty of vegetables with a small amount of protein. You can also try steaming fish and seafood, simmering chicken in a sauce and braising red meat in liquid.

Omega-3 supplements may prevent skin cancer

The many benefits of omega-3 supplementation, from heart health to anti-inflammatory effects in conditions such as arthritis, are well-known. A new study conducted by researchers at Manchester University has now investigated the potential of omega-3 to protect against skin cancer (1).

Skin cancer is a growing concern in the UK, where rates of malignant melanoma have increased significantly over the last 30 years. In fact, according to Cancer Research UK, incidence rates of this type of cancer have increased more rapidly than any other type of cancer (2). And it is not just a concern for the elderly. In the UK, more than 700 young people between the ages of 17 and 34 are diagnosed with skin cancer every year.

The study is the first of its kind to test the protective benefits of omega-3 on human volunteers. The volunteers were given either a 4g dose of omega-3 or a placebo supplement. They were then exposed to the equivalent of either 8, 15 or 30 minutes of summer midday sun through the use of a light machine.

This study measured the amount of damage to the immune system, or ‘immunosuppression’ caused by sunlight. Sun exposure and sunburn can actually suppress the immune system, and repeated exposure can cause long term damage to the immune system, making your body more susceptible to skin cancer. The results of this study showed that immunosuppression was 50% lower in those who took the supplement compared to those who were given a placebo.

The beneficial effects were noted in those who were exposed to 8 and 15 minutes of sun, but were not seen in those who underwent 30 minutes of exposure.

Professor Lesley Rhodes at the University’s Photobiology Unit, said this was the first time a study such as this has been carried out on humans. “This study adds to the evidence that omega-3 is a potential nutrient to protect against skin cancer. Although the changes we found when someone took the oil were small, they suggest that a continuous low level of chemoprevention from taking omega-3 could reduce the risk of skin cancer over an individual’s lifetime.”

Other nutritional lines of defence from the sun’s UV rays include antioxidants, which ‘mop up’ some of the oxidative damage caused by the sun. For example, previous research suggests that skin damage from the sun can be reduced by taking 2000mg of Vitamin C alongside 1000IU Vitamin E (3). Citrus fruits are the most obvious choice for those wanting to increase their Vitamin C intake, although green peppers, broccoli and green leafy vegetables are similarly beneficial. Garnishing your meals with chopped almonds, sunflower seeds, pine nuts or a drizzle of olive oil will also give Vitamin E levels a boost.

While omega-3 oils and antioxidants are no substitute for suncream, these studies suggests it may provide helpful support alongside our usual protective measures. Research into the nutrition’s protective benefits for the skin continues, and Professor Rhodes’ team are currently continuing their investigations with omega-3 at Salford Royal Hospital.
