Most of the food we eat will adequately support life. \u00a0But it does not necessarily sustain ideal health. Witness the latest alarming data (2015) from the UK’s Office for National Statistics (ONS) which shows that life expectancy<\/span> is increasing, but healthy<\/strong> life expectancy<\/span> is not.<\/p>\n Even people in the upper income levels face, on average, living the last 8 years of their life in poor health, and being reliant on an increasing array of medicines and medical interventions.<\/p>\n People in the lowest economic levels can face 12 <\/span><\/strong>of their last years in ill health! [see data here<\/a>]<\/p>\n It must not be, and doesn\u2019t have to be, like this.<\/p>\n National surveys show that many people are deficient in individual vitamins and minerals. [see some extracts from a recent UK survey here<\/a>] However, that is not \u2013 in our opinion \u2013 the real reason to consider a supplement.<\/p>\n Because most of these people do NOT eat a well-balanced diet.<\/p>\n Assuming you, however, do have a healthy lifestyle and eat a really<\/u> well balanced daily diet, you probably can get almost all of your Recommended Daily Allowances (RDAs) of vitamins and minerals, from food. (The exception probably being vitamin D in the winter in the northern hemisphere.)<\/p>\n So you are unlikely to be seriously deficient in any particular vitamin or mineral as measured against RDAs<\/span>. (We will use the term RDA although this is often now referred to on labels as RNI \u2013 Reference Nutritional Intake.)<\/p>\n BUT \u2013 and it\u2019s a big but \u2013 these RDAs are calculated on the level you need to prevent overt deficiency diseases. The RDA for vitamin C prevents scurvy and the RDA for vitamin D prevents rickets. But that is a low threshold.<\/p>\n Whether the RDAs are enough to sustain ideal long-term health is entirely another matter.<\/p>\n Vitamin C and vitamin D are good examples. The UK RDA for Vitamin C<\/strong> is 80mg a day. Extensive evidence (reviewed later) shows that an optimum level of 500mg brings major health benefits, but they are not found at the minimal RDA level.<\/p>\n The UK RDA for Vitamin D<\/strong> is just 5 mcg \u2013 whereas current university researchers in the field are recommending a supplement of between 25 mcg and 50 mcg a day in the winter.<\/p>\n A level of 5 mcg a day might prevent immediate disease \u2013 but the higher optimum levels have been shown to confer major long term benefits such as a reduction in the risk of bone fractures, some cancers and dementia.<\/p>\n In terms of optimum health, we seemingly set our sights too low. We are, for example, urged to eat 5<\/span><\/strong> portions of fruits and vegetables a day. The average is less than 3. The American Cancer Society recommends 9 portions a day.<\/p>\n An even more important point is that vitamins and minerals are far<\/em> from the only nutrients that we need for optimum health.<\/p>\n Research shows that nutrients like Omega 3<\/strong>, curcumin<\/strong>, lycopene<\/strong>, lutein<\/strong>, betaine<\/strong>, Co Q10<\/strong>, soy isoflavones<\/strong> and the polyphenols and flavonoids <\/strong>in fruits, green vegetables or green tea are just as important for health as vitamins and minerals \u2013 but no RDA has yet been established for them.<\/p>\n To take an example, although there is not yet an RDA for Omega 3, we are advised to eat 2-4 portions of oily fish a week, which would average 1,000 mg a day. The current average intake is 142 mg a day.<\/p>\n A far better criterion for assessing how foods and supplements really impact on long term health is this:<\/p>\n Those six reasons are:<\/p>\n These six problems \u2013 or normally a combination of them \u2013 underlie all the killer diseases like heart disease, stroke, cancer, Alzheimer\u2019s and diabetes.<\/p>\n Although these illnesses are often termed \u2018age related\u2019 diseases, the term is misleading. These illnesses are not so much due to the passing of the years, but rather to the accumulated damage to DNA and tissue caused by excess free radicals, inflammation, errors in cell renewal, decline in immune function, and adverse gene expression.<\/p>\n Ageing<\/strong> is scientifically defined as:<\/p>\n \u2018the progressive accumulation of damage to an organism over time leading to disease and death\u2019<\/p><\/blockquote>\n Some evidence for this assertion goes back to the ONS statistics quoted earlier. Leaving aside the unfairness of the inequalities involved, in economically deprived areas the average person lives 10 to 12 years in poor health.<\/p>\n In the economically most advantaged areas the years of poor health are reduced to 8\u00a0 \u2013 mostly because such people can generally afford to eat better foods and adopt a healthier lifestyle. Moreover, such people are more likely to educate themselves on health.<\/p>\n But even 8 years in sub-optimal health is neither acceptable nor necessary.<\/p>\n We now have research to show that achieving a long, healthy life expectancy needs a combination of a wide range of nutrients at optimal<\/strong> levels \u2013 well beyond just meeting the RDA for vitamins and minerals. (And supported, of course, by regular exercise\/physical activity.)<\/p>\n Whereas conventional pharmaceutical medicine is focused on treating the symptoms<\/em> of age-related disease when it has surfaced, \u2018nutraceutical\u2019 science is focusing on prevention<\/em> through optimal levels of food and nutrition.<\/p>\n Prevention has to start early \u2013 because diseases like coronary heart disease, cancer and Alzheimer\u2019s do not occur suddenly, even though they may seem to. Most take 15-20 years to develop to the point they are clinically noticeable.<\/p>\n Dr Robert Heaney is one of the world\u2019s leading vitamin D researchers.\u00a0 In The American Journal of Clinical Nutrition<\/em>\u00a0he talks about the fallacy of relying on RDAs and the serious consequences of taking less than the optimal amounts of nutrients for health:<\/p>\n \u201cbecause the current [vitamin] recommendations are based on the prevention of deficiency diseases only, they can no longer be said to be biologically defensible.\u201d<\/p><\/blockquote>\n The case for optimum<\/strong> nutritional levels, rather than minimum RDA levels, was set out clearly by Dr Paul Clayton in his seminal book Health Defence<\/em>. Dr Clayton is a former president of the Forum on Food and Health at the Royal Society of Medicine.<\/p>\n His conviction is that good health can be maintained, and ageing slowed down, by the right foods, supported by a careful combination of supplements. These should reproduce the range and levels of nutrients found in the diets of the longest-lived people in the healthiest societies. There are pockets of ultra-long-lived populations around the world called \u2018Blue Zones<\/strong>\u2019 and his recommendation draws lessons from them.<\/p>\n As mentioned previously, there is a critical difference between a nutritional intake that simply prevents deficiency and an optimal intake that significantly cuts the risk of \u2018age related\u2019 disease by counteracting the root causes of long term illness.<\/p>\n A supplement is never a replacement for eating healthy food. But without extra support from a well-designed supplement, very few people in a modern society \u2013 even if they adopt a healthy lifestyle \u2013 will get the OPTIMUM intake of all the proven health defensive nutrients on a continuous DAILY basis.<\/p>\n Moreover, the definition of a healthy lifestyle is pretty challenging. It includes:<\/p>\n Not many of us can live up to that standard.<\/p>\n But before we examine what an ideal supplement might look like, let\u2019s answer the three common objections to them.<\/p>\n True \u2013 but back then we were highly active and eating an estimated 4,000<\/span> calories a day \u2013 largely plant based. Now \u2013 unless we risk weight gain and obesity \u2013 it is nearer 2,000<\/span> calories a day. And less food means less nutrient content as well as fewer calories!<\/p>\n In addition, a good proportion of what we eat nowadays is in the form of processed foods<\/em> which are lower in nutritional quality.<\/p>\n In particular most of us have an unhealthy balance of Omega 6 to Omega 3 oils.<\/p>\n Fats such as palm oil, corn oil, butter substitutes and sunflower oil in processed foods, snack foods, fast foods, mayonnaise, cakes, biscuits and pastries all contain Omega 6. This accounts for the fact that we now have an intake ratio of Omega 6 oils to Omega 3 oils which is FAR too high \u2013 about 17:1<\/span> when it should be nearly 1:1<\/span>.<\/p>\n Excess Omega 6 is strongly linked to inflammation, which in turn is a key driver of heart disease, stroke, diabetes and some cancers.<\/p>\n In contrast Omega 3 oil is an anti-inflammatory, but the average diet is sub-optimal in Omega 3, as the best source is oily fish \u2013 experts recommend 2 – 4 portions a week. The average is less than one.<\/p>\n Even the fresh foods we buy can be lower in nutritional value than they were as little as 40 years ago. Intensive and single-crop (monocrop) farming have depleted mineral levels in the soil and lengthy long-distance supply chains have made the problem worse.<\/p>\n A survey in Scientific American <\/em>confirms that …<\/p>\n “… crops grown decades ago were much richer in vitamins and minerals than the varieties most of us get today”<\/p><\/blockquote>\n It\u2019s not a scare story. A University of Texas study published in December 2004 in the\u00a0Journal of the American College of Nutrition<\/em> showed …<\/p>\n “… reliable declines in the amount of protein, calcium, phosphorus, iron, riboflavin and vitamin C, magnesium, zinc and vitamins B6 and E over the past half century in 43 different vegetables and fruits”<\/p><\/blockquote>\n The findings are confirmed by many other surveys.<\/p>\n It\u2019s not just plant foods. Intensive farming of animals for meat means, for example, that they need to be treated with antibiotics. Not only is that causing dangerous antibiotic resistance, but methane output in such cattle is double the normal amount \u2013 and a serious contributor to global warming.<\/p>\n Ironically, increases in life expectancy also increase the need for extra nutrition \u2013 because we become less able to absorb nutrients from food as we age.<\/p>\n Other aspects of modern life have increased the need for extra micronutrient intake:<\/p>\n So, yes people did evolve and live without supplements, but the nutritional demands on us have now changed and increased.<\/p>\n Doctors know a lot about drugs \u2013 but generally a lot less about nutrition!<\/p>\n The National Institutes of Health<\/em> is the biomedical research facility of the United States Department of\u00a0Health.\u00a0They surveyed the amount of nutritional education in US medical schools.<\/p>\n The average was less than 20 hours of instruction in 4 years of medical school ie. just 20 hours over a typical 40,000 hours of total training to be fully qualified. The same is true in the UK.<\/p>\n Compounding the problem is that most practising doctors\u00a0completed their minimal nutrition training years or even decades ago, and have rarely updated themselves since then. As a researcher dryly noted: \u201cThe receptionist often knows more than the doctor!\u201d<\/p>\n Doctors tend to favour drugs, which are fast-acting, over nutrition which takes time to have an effect. Physicians are also inevitably influenced by the pharmaceutical industry and \u2018Big Pharma\u2019s\u2019 business model is to encourage the prescription of patented, high margin drugs, not foods or nutritional supplements that cannot be patented.<\/p>\n In contrast to drugs, however, the right foods and combination of nutrients can be preventative \u2013 working naturally with and enhancing the body\u2019s own biochemistry.<\/p>\n Some, yes \u2013 but the overall results are mixed.<\/p>\n For example the Physicians\u2019 Health Study II<\/em> investigated the effects of daily multi-vitamin use in over 14,000 middle-aged, male doctors. It found no reduction in heart attacks<\/span> or strokes<\/span>, and no reduction in mortality.<\/p>\n However, a 2015 study on 8,678 women, published in The Journal of Nutrition<\/em>, found that those women who took a multivitamin for at least three years had a 35% lower risk of dying from heart disease.<\/p>\n Some studies on the use of multi-vitamins have found no effect on cancer<\/span> risk. On the other hand a large meta-survey, combining the results from 5 randomized, controlled trials and involving 47,289 participants, found a 31% lower risk of cancer in men, but no effect in women.<\/p>\n Can multivitamins improve brain function<\/span>? Again the results are mixed. A placebo-controlled, double-blind study (the gold standard) on elderly women did show improvements in memory \u2013 but not on general reasoning tasks.<\/p>\n The confusion is not surprising. We would not expect a simple, RDA-based, multivitamin and mineral pill to make a lot of difference \u2013 especially to a person already eating healthily. The levels are not optimum nor is the range of nutrients enough.<\/p>\n No less an authority than the Journal of the American Medical Association agrees. A scientific review of 150 clinical trials published by them concludes that:<\/p>\n “… the normal diet is sufficient to prevent overt vitamin deficiency<\/em> diseases such as scurvy, pellagra, and beriberi.<\/p>\n “But recent evidence has shown that suboptimal<\/em> levels of vitamins, even those well above those causing deficiency syndromes, are risk factors for chronic diseases such as cardiovascular disease, cancer, and osteoporosis.<\/p>\n “A large proportion of the general population is apparently at increased risk for this reason.”<\/p><\/blockquote>\n [Our emphasis on deficiency and suboptimal.]<\/p>\n So let\u2019s now change the initial question.<\/p>\n On the basis of this article, the answer is a supplement containing nutrients that are shown to help prevent, reduce or slow:<\/p>\n 1. Damage to DNA That supplement should also contain nutrients that can help \u2018turn on\u2019 protective genes, and \u2018turn off\u2019 damaging genes like oncogenes.<\/p>\n The following list of protective nutrients is compiled from literally thousands of peer reviewed scientific studies. You\u2019ll see that some nutrients have more than one role in a multiple health defence strategy. They should all be in included in a genuinely effective supplement.<\/p>\n Humans have extensive DNA repair mechanisms, but these begin to weaken with age, causing DNA damage to accumulate. This not only accelerates ageing, but increases the risk of cancers and, for example, the irreversible eye disease macular degeneration<\/em>.<\/p>\n The carotenoids lycopene<\/strong>, lutein<\/strong> and zeaxanthin<\/strong> have been shown to assist DNA repair and reduce damage \u2013 as have the minerals selenium<\/strong> and zinc<\/strong>.<\/p>\n Grapeseed extract<\/strong> \u2013 rich in plant polyphenols called anthocyanins – has also been shown to block breast cancer cell DNA damage.<\/p>\n Oxidation or excess free radical action is also a factor in DNA damage and vitamin C<\/strong>, vitamin E<\/strong> and CoQ10<\/strong> are all powerful antioxidants at the right level.<\/p>\n \u2018Chronic, sub-clinical inflammation\u2019<\/em> is now known to be a major cause of the degenerative killer diseases.<\/p>\n This type of inflammation builds up in tissues over time, but you can\u2019t see or feel it \u2013 which is why Time Magazine<\/em> calls it \u2018the silent killer\u2019.<\/p>\n New Scientist<\/em> recently confirmed that …<\/p>\n “… inflammation is involved in muscle wasting and glaucoma, Alzheimer\u2019s and Parkinson\u2019s, osteoporosis and arthritis, heart failure and high blood pressure, cancers, and lung, liver and kidney and skin disorders.”<\/p><\/blockquote>\n The incidence of inflammation increases with age and is a risk factor for most people after the age of about 50. The risks rise even further if you live in a city and are exposed to air pollution.<\/p>\n Some of the most potent anti-inflammatory supplement nutrients are Omega 3<\/strong> fish oil, curcumin<\/strong>, the plant polyphenols in green tea<\/strong> and anthocyanins<\/strong> which are the nutrients that contribute the rich red, blue and purple colours to the leaves, roots and fruits of plants.<\/p>\n An anti-inflammatory diet includes oily fish, berry fruits, olive oil, tomatoes, leafy green vegetables and nuts. It also calls for less refined carbs, processed meats and fried foods.<\/p>\n Your immune system defends you against pathogen invaders like viruses and dangerous bacteria and against internal \u2018rogue\u2019 cells like cancer.<\/p>\n Supplement nutrients that support the immune system include vitamin A, beta carotene, vitamin D, vitamin E, curcumin, green tea extract, selenium, zinc <\/strong>and lycopene<\/strong>.<\/p>\n Every one of the billions of cells that you make every day needs a source of high quality fats in the diet to form a healthy, flexible outer membrane. Omega 3<\/strong> from oily fish is an ideal source.<\/p>\n Researchers have found that vitamin D<\/strong>, the carotenoid lycopene<\/strong>, the xanthophyll carotenoid lutein<\/strong> and the B vitamin choline<\/strong> are important to ensure normal cell signalling and, by extension, cut the risk of cancer.<\/p>\n The American National Institutes of Health<\/em> website Pub Med<\/em> confirms that<\/p>\n “carotenoids can be useful in the prevention of cancer and other degenerative diseases”<\/p><\/blockquote>\n Healthy cells also need CoQ10<\/strong>.<\/p>\n Inside almost every cell in your body are mitochondria \u2013 the tiny \u2018power plants’ that help break down food and create energy.<\/p>\n A significant factor in ageing and disease is a progressive loss of mitochondrial function \u2013 which can result in lower energy levels, heart disease, diabetes and neurological problems.<\/p>\n Mitochondrial cells include DNA and because of the high energy levels created within them \u2013 especially in heart cells \u2013 mitochondrial DNA is very vulnerable to oxidation or free radical damage.<\/p>\n Coenzyme Q10<\/strong> is a vital nutrient within the mitochondria and an amazing 95%<\/strong>\u00a0of all cellular energy production depends on it.<\/p>\n Unfortunately levels of CoQ10 peak at about 20 years of age and decline continuously thereafter. However studies show that CoQ10 supplementation can boost mitochondrial function and total energy output in heart muscle, as well as protect tissue from DNA damage.<\/p>\n CoQ10 is also a powerful anti-oxidant and one of the few nutrients that can enter mitochondrial cells. There it counteracts the damage caused by free radicals. The more CoQ10 that is available to the mitochondria, the less free radical damage and potentially the slower you age.<\/p>\n CoQ10 is not the only important heart nutrient. Studies show that a nutrient called betaine,<\/strong> with other B vitamins and folic acid, can lower a dangerous blood protein called homocysteine. High levels of homocysteine lead to an elevated risk of heart attacks.<\/p>\n Food sources of CoQ10 are mainly organ meats like kidney and liver, plus beef, sardines and mackerel. Betaine is found in quinoa, wheat bran and beets (which is where its name comes from).<\/p>\n Glycation is when a sugar molecule binds to a protein. This \u2018sugar coating\u2019 leads to tissues becoming \u2018cross linked\u2019, rigid and less pliable. \u00a0It is strongly linked to accelerated ageing, wrinkles and more seriously, a worsening of degenerative diseases like diabetes, cataracts, atherosclerosis, kidney disease and Alzheimer\u2019s.<\/p>\n Glycation is mainly a function of excess sugar and carbohydrates in the diet, together with high temperature cooking like frying and roasting. Hence it\u2019s more about what you do NOT eat \u2013 and exercising enough to burn up the sugars in your bloodstream.<\/p>\n However, studies show that the B vitamins<\/strong> B1<\/strong>, B6 <\/strong>and folic acid<\/strong> may help reverse the damage caused by glycation.<\/p>\n Certain nutrients can upregulate or turn on \u2018good\u2019 genes \u2013 like tumour suppressor genes. And others can down-regulate or turn off \u2018bad\u2019 genes \u2013 such as oncogenes which have the potential to cause tumours.<\/p>\n It\u2019s called \u2018gene expression\u2019, part of a new science called epigenetics.<\/span><\/p>\n Scientists in this emerging field have identified a number of nutrients that can trigger positive gene expression \u2013 they include betaine, folic acid, choline, vitamin B12, vitamin D, lycopene, selenium, lutein, green tea and genistein<\/strong> which is derived from soy.<\/p>\n The above is a summary of the range of nutrients that can make a genuine difference to health. But that\u2019s only one aspect.<\/p>\n They now need to be brought together in a synergistic combination at optimum levels.<\/p>\n The optimum research-based levels for the main nutrients are listed here<\/a>.<\/p>\n But let\u2019s look at how the \u2018adequate\u2019 versus \u2018optimum\u2019 argument plays out for one common but vital vitamin – vitamin C.<\/p>\n The EU RDA\/RNI for vitamin C is 80 mg. Now here is what vitamin C does:<\/p>\n Research shows that vitamin C can also achieve the following \u2013 BUT only at levels that average 500 mg<\/strong> a day \u2013 over 6 times the RDA:<\/p>\n The results of optimising<\/strong> vitamin C levels give the lie to critics that dismiss supplements as \u2018only creating expensive urine\u2019.<\/p>\n In fact, the body absorbs ALL the vitamin C it needs \u2013 and a single 500 mg dose is almost 100% absorbed through an active transport process.<\/p>\n It is true that a decreasing percentage is absorbed at much higher doses and that the upper safe limit for long term use has been set at 1,000 mg a day.<\/p>\n We\u2019ve seen that there are multiple ways in which health can deteriorate as we get older. To defend against these threats you need multiple nutrients – nutrients that research shows have the power to counteract these threats. This combination must be at optimum<\/u> levels.<\/p>\n However conscientious you are, it is difficult to eat to achieve a continuous DAILY intake of nutrients as diverse as lutein, lycopene, Omega 3, curcumin, beta carotene, CoQ10, \u00a0polyphenols like anthocyanins, green tea, and the isoflavone genistein.<\/p>\n Let alone to reach the optimum<\/u> rather than just RDA levels of all the essential vitamins and minerals.<\/p>\n That\u2019s why the multiple ingredient supplement called NutriShield Premium<\/u> was originally developed by Dr Paul Clayton. It includes all the nutrients we have identified, in the most bio-available forms, combined in a comprehensive, highly concentrated, zero calorie health supplement.<\/p>\n Of course this high level of nutrition cannot be put into just one vitamin pill. NutriShield Premium <\/u>consists of 6 daily caplets packed into a tear open sachet \u2013 which saves not only buying multiple bottles of supplements, but ensures the nutrients are always optimally balanced.<\/p>\n The full list and levels are given here<\/a>.<\/p>\n Naturally NutriShield Premium costs more than a simple vitamin pill but \u2013 like eating well \u2013 the investment is comparatively minor compared to the long term gains.<\/p>\n <\/p>\n If you enjoyed this article, please share it with family and friends.
