When the press release arrived in our inboxes, we knew what would happen next. A Nobel laureate had stated that antioxidant supplements "may have caused more cancers than they have prevented. " Even the most fad-friendly sections of the UK media were bound to cover the story. In reality, Professor James Watson was only restating what we at Cancer Research UK have been pointing out for years. Large studies have repeatedly shown that, with the possible exception of vitamin D, antioxidant supplements have negligible positive effect on healthy people, at least in terms of important things such as preventing people getting cancer or dying prematurely. And some supplements—notably vitamins A, E and beta- carotene—even seem to slightly raise the risk of disease and early death. It’s a topic we at Cancer Research UK come back to again and again on our science blog and on our social media pages. But huge swatches of the public remain convinced that "antioxidant" is a byword for "healthy. " What’s so interesting about the antioxidant myth is its wider cultural and social dimension. Why is this perception so hard to shift And is there anything we can do about it One possible reason for our firm attitudes is the widespread use of the word "antioxidants" in adverts proclaiming the health benefits of various foods and drinks. This isn’t for want of regulation, and the Advertising Standards Authority have repeatedly upheld complaints about adverts that make unsupported claims about antioxidants’benefits. But the much weaker claim that a product merely "contains high levels of antioxidants" leaves health claims implicit, and keeps regulators at bay. A brand of "super- broccoli"—launched with much a public spectacle in late 2011—was bred to contain high levels of a chemical that ultimately, according to the product’s website, "boosts our body’s Antioxidant Enzyme levels. " So good it’s capitalized. So the relentless drip-drip of health product advertising—particularly against a background of continual reports of Britain’s ill-health—makes our trenchant hold on the antioxidants myth all the more understandable. We need this stuff, we’re told. But there’s probably a deeper reason for our collective refusal to swallow the bitter pill of scientific evidence. The actual, proven things that can reduce our risks of cancer, heart disease, diabetes—and all the other chronic nasties that come with an ageing population— are somewhat more uninteresting. Don’t smoke. Stay in shape. Eat a balanced diet. Limit alcohol intake. Keep active. This is hard work. And as the resolution-filled new year kicks in, the exciting prospect of a healthier life is replaced by the realization that being healthy is a long-term project. Popping a pill instead of going to the gym is a tempting prospect for many of us. Confirmatory bias is a powerful thing. But the UK population is ageing, and likely to place a greater burden on the NHS in future. We owe it to ourselves, and those will be paying for our care, to make sure we’re as healthy as possible for as long as possible. Putting our faith in a word, and a pill— however comforting it may sound—to do this for us is a mirage and a fallacy. Antioxidants do not prolong our lives nor prevent cancer, despite what we want to believe. It can be concluded that people’s collective belief in antioxidants is NOT based on ______.

Our stomachs can often be a mystery to us and many of us don’t realize just how much the food we eat can impact on our mood and mental well-being. According to charity Allergy UK, a shocking 45% of us suffers with food and drink intolerances, beverage—this is called food intolerance. Food intolerance is a much more common problem than food allergy and one of the most harmful symptoms can be low mood. 1 in 4 people in the UK will suffer problems with their mood or mental health every year, with anti-depressant prescriptions increasing by over 40% in the last 5 years. Recent research from York Test Laboratories, leading experts in food intolerance testing, has found that 97% of their customers reported problems relating to mood as a significant symptom of their food intolerance, of which 73% felt that their mood had significantly improved after altering their diets to remove foods to which they reacted. In addition, in a recent paper published in the Journal of Nutrition and Food Sciences, over 81% of patients reported a significant improvement in mood and mental well- being as a direct consequence of applying the dietary changes recommended by York Test. So how is it that the food we eat can have such a significant impact on our mood Bidirectional connections between the gut and the brain are complex and are regulated in the body in three different ways: through nerves, hormones and the immune system. The gut mediates the body’s immune response; at least 70 per cent of our immune system is situated in the gut and is used to expel and kill foreign invaders. Our gut contains some 100 million neurons (nerve cells), more than in either the spinal cord or the peripheral nervous system. All of these neurons lining our digestive system do much more than merely handle digestion or cause occasional nervous feelings. Our gut partly determines our mental state and plays key roles in certain diseases throughout the body. Many people will not be aware that 90% of serotonin(血清素), the brain’s "happy hormone" is produced in the gut—it is for these reasons that the gut is often referred to as the ’second brain’. In addition, research has shown that depression is frequently associated with gastrointestinal (肠胃的) inflammation—a common symptom of food intolerance. By tackling unidentified food intolerances, not only will physical symptoms benefit, but mental health symptoms can often show significant improvement. There are a number of ways to identify potentially mood suppressing food intolerances. One that I recommend is scientifically validated and well researched is York Test. Its food and drink intolerance test called Food & Drink Scan can uncover potential food and drink triggers, allowing people to simply modify their diets with life changing health benef What frequently has a causal connection with depression
