For a number of years I have been concerned about the proliferation of unsafe nutritional products and improved health claims based on “junk” science. How do you believe? Who do you trust? The average consumer believes that if it is on the shelf it must be safe. However some nutritional products do not even contain what listed on the label. So what is the consumer to do?
Resveratrol is a phytoalexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi. Resveratrol has also been produced by chemical synthesis, and is sold as a nutritional supplement derived primarily from Japanese knotweed. A number of beneficial health effects, such as anti-cancer, antiviral, neuroprotective, anti-aging, and anti-inflammatory effects, have been reported. Resveratrol is found in the skin of red grapes and is a constituent of red wine but, based on extrapolation from animal trials, apparently not in sufficient amounts to explain the “French paradox” that the incidence of coronary heart disease is relatively low in southern France despite high dietary intake of saturated fats.
