Studies have shown that resveratrol in red wine does not seem to prevent heart disease and cancer

2015-03-03 classification: efficacy, plant industry trends a new study shows that resveratrol, a substance found in red wine, grapes and chocolate, does not seem to be able to fight aging and prevent cancer Dr Richard Semba, chief researcher of Ophthalmology professor at Johns Hopkins University School of medicine in Baltimore, found that when it comes to diet, health and aging, things are often not so simple, and it may not be due to the role of a single substance, such as resveratrol At the same time, his research also made him doubt the effect of resveratrol supplements "Maybe it brings us back to a really reliable diet - Mediterranean style eating habits and regular aerobic exercise are the real ways to fight aging." The report was published in the internal medicine section of the online edition of the Journal of the American Medical Association on May 12, 2014 Red wine and chocolate have been shown to be beneficial to health, and for these beneficial effects, it is often attributed to a single substance - resveratrol Resveratrol is known as the so-called "French paradox", and researchers explain that it is healthy to eat foods with high cholesterol and fat as long as they are accompanied by red wine As we all know, the French like food, including high cholesterol, high fat food, but the proportion of cardiovascular disease is lower than other countries - this phenomenon is known as the "French paradox" Semba's team studied nearly 800 men and women aged 65 or over in two villages in the Chianti red wine region from 1998 to 2009 The researchers found that these people eat a diet rich in resveratrol To find out whether resveratrol in the diet actually reduces the risk of cancer, heart disease and death, the researchers measured the traces of resveratrol in participants' urine During the follow-up period, 286 (34.3%) died; 174 (27.2%) had heart disease and 34 (4.6%) had cancer, the researchers found When the researchers measured resveratrol levels, they did not find a significant difference between the highest and lowest death rates They also found no association between high levels of resveratrol and low levels of resveratrol in reducing the risk of heart disease or cancer In fact, the lowest risk of heart disease was among those with the lowest levels of resveratrol Based on the most conservative extrapolation from Dr Semba's study, resveratrol in the diet did not translate into fewer deaths, cancer or heart disease Samantha Heller, a senior clinical nutritionist at New York University Medical Center, said: "a quick search in the medical literature found that many of the resveratrol studies in that year were conducted in vitro or in animals These studies seem to show that for humans, increasing resveratrol rich foods in their diet, such as red grapes and wine, can affect long-term health for more than nine years It may be that the effect of resveratrol in diet is not obvious " "Resveratrol seems to be a green light for people who want to drink," Heller said Many of my patients asked me, 'should I start or continue drinking? Isn't he good for the heart One of the main reasons people think this is because resveratrol is thought to be good for heart health, Heller said However, drinking too much alcohol in any form is toxic "Although some studies show that regular use of red wine is good for health, in fact, many of us drink too much wine, which can affect liver and brain functions, as well as blood sugar and weight over time," Heller said Fruits and vegetables are rich in phytochemicals including resveratrol, vitamins and minerals that work together to help promote health and fight disease "Red grapes, peanuts, strawberries and other resveratrol containing foods play an important role in our diet However, because the food we eat is not a single nutrient or compound, we must remember that we want to see what we eat and how we live from the whole panorama," hleller reminded Current research and common sense suggest that a more plant-based diet and regular exercise are more helpful for long-term health, Heller added "This is not to say that a glass of wine is not a healthy choice right now The American Heart Association recommends one to two drinks a day for men and one for women on average Heller finally said Based on all the data published so far, no definite research experiment has been found to prove the efficacy of resveratrol If you have other information to support or refute this article, please leave a message after the article and participate in the discussion Source: Richard Semba, M.D., m.p.h., Professor of Ophthalmology, Johns Hopkins University School of medicine, Baltimore; Samantha Heller, M.S., R.D., senior clinical nutrition, New York University Medical Center, New York City; May 12, 2014, JAMA internal medicine, online
