Resveratrol
Resveratrol is a polyphenolic compound present in grapes, and is most well known for its presence in red Wine. Interestingly, the popularity of resveratrol is due to its discovery in red wine and subsequent hypothesizing that it may be able to explain the ‘French paradox’ of Heart Disease. However, resveratrol only contributes slightly to the french paradox, as Alcohol (from red wine), diet and lifestyle are also significant factors. It is estimated to have an average intake of 0.2mg daily in a Spanish population, mostly (98.4%) from wine. North Americans tend to have minute levels in the diet. Interestingly, it is classified as a phytoalexin (plant toxin). Its reason for existence is to protect grapes from infection, as it is synthesized in response to Bothrytis cinerea infection.
