The supplements may not can prevent aging

Experts say diet cures more than the doctor

China's traditional Chinese medicine reported

        Even if no relevant areas of scientific knowledge, as long as you is to healthy more interested in people I'm afraid all heard "antioxidant", "free radicals" of the words, and that is a series of contact tea polyphenols, polysaccharide, grape seed, procyanidins, soy isoflavone have well-known component. Now in food, health care products field, as long as take "antioxidant" words, often let people lining up. But what is oxidation resistance, resistance to oxidation and the distance between the anti-aging how far away? The truth may not like the public wants optimistic.

        Theory: antioxidant content can prevent cell damage

         "Antioxidant", "free radicals" these words are in fact not from a healthy area of research, but from other areas evolution.

        The Chinese nutrition society member of the standing committee of XuHuaFeng said, physical chemist Abraham · haman's in the last century 40 s found that the oil industry's "free radicals" theory can be used to explain human aging phenomenon, and further puts forward after antioxidants can slow aging theory. Any need oxygen to maintain normal growth and development and function activities in the individual will have a reactive oxygen species, the most common had oxygen free radicals, nitrogen, oxygen free radicals, etc.

        The free radicals because is more active, will the latest electronic rob come over, so in certain circumstances will bring some damage to cells, and causes irreversible cell aging. Haman think cell aging can lead to cancer, cardiovascular disease, rheumatoid arthritis, Parkinson's disease and increase rate of disease.

        XuHuaFeng said, the human body itself also has certain antioxidant system, but now people also unceasingly in the diet in search for possible antioxidants. Such as vitamin E, kind of carotene, vitamin c, zinc, selenium, fatty acid and so on many kinds of nutrients, and tea polyphenols, polysaccharide, grape seed, procyanidins, soy isoflavone food composition has obvious antioxidant effect. "Antioxidant action principle is the electronic and free radicals, prevent cell damage with production."

        Dispute: antioxidant application research of support

        Although the scientific community against oxidation mechanism has had certain understanding, but whether to use the application to medical function is a very controversial issue.

        General hospital of Beijing military area of doctor and YuBin said heart medicine, although in recent years about the antioxidants in clinical application research a lot, but can reach definite conclusion only a little, and even a few studies also found that the supplements will cause harm to the body. Like many foreign countries and clinical nutrition research found that human antioxidant supplements and can't effectively prevent coronary atherosclerosis. And some related to hundreds of thousands of large clinical trials also does not draw human antioxidant supplements to reduce mortality have help conclusion.

        And YuBin said, antioxidant for clinical use at present has many problems. First is not enough research as a support, some epidemiological study found that usually eat more vegetables, fruit crowd in certain disease on the prevalence of low. But this does not mean that is the antioxidants in vegetables played a role, or maybe it's because this dietary structure to this group provides enough other nutrient elements; Second, even if some of the theory has been confirmed in clinical application also need a long time process, finally pass clinical test and verify. At present antioxidant clinical applications are still not very likely.

        As the supplements are difficult

        1998 Nobel Prize in physiology medicine winner jose mourinho radmanovic, says dr, how to take antioxidant supplements also is at present the scientific community faces a difficult. Antioxidants can play the antioxidant effect is extremely easily because they itself by oxidation, so can before cells and oxidation. This also brings another problem, extremely easy oxidation of antioxidants when exposed to the air could have easily by oxidation, and some antioxidants oxidation's products are harmful to human body. Such as the coffee and tea polyphenols in human environment will be produced hydrogen peroxide oxidation, and hydrogen peroxide itself is very active, will oxidation cells.

        Mourinho, says dr radmanovic, some produced artificially antioxidant consumption is faster, may enter the body also do role. Relatively few natural plants contains antioxidants in the body and can produce antioxidant material is stable, able to enter the body. Such as some fibrous vegetables and fruit antioxidants, entering the human body in the digestive system up time is longer. So now or advise people don't mess with the big doses of supplements or rich in antioxidants of health products, insist to eat some flavonoid-rich foods, tea, fruits and vegetables. (HeXiao)
