![]() Examples include tea, cocoa, extra virgin olive oil, legumes, grains, and berries.įocusing on foods and non-alcoholic beverages derived from grapes and other polyphenols should be prioritized when composing a healthy diet. The good news is that resveratrol belongs to the larger class of phytochemicals called polyphenols that are ubiquitous in almost every plant-based food consumed in the human diet. Much more research is needed before claims can apply to humans.īut decades of scientific research have pointed to the beneficial effects of resveratrol, including its inhibitory role in cancer initiation, promotion, and progression. Answers to questions such as, “How much resveratrol would an individual need to produce the same effect?” and “Would the effect of resveratrol change if it were consumed as part of a whole food?” remain unclear. The study supports numerous experimental studies investigating the beneficial effects of resveratrol in vitro (cell culture) and in vivo (among animals) but provides limited promise for how the results could translate to humans. AICR recommends that if you do drink, limit to 1 drink or less for women and 2 or less for men per day. Heavy alcohol use is also associated with multiple cancers. And red wine makes a catchy headline.īut although red wine is a source of resveratrol, it carries side effects with it such as being highly concentrated in calories and alcohol, all of which can promote weight gain and increase risk for disease when consumed in large quantities and over the long-term. ![]() So why the leap to red wine in recent headlines? Resveratrol is primarily concentrated in grapes and a limited number of other foods such as peanuts and some berries. ![]() The authors determined that resveratrol converts a type of fat called white adipose tissue into brown fat, which is a more metabolically active (and energy-burning) type of fat that can lead to weight loss. The headlines on red wine and weight loss stemmed from a recent animal study investigating the effects of a purified form of the phytochemical resveratrol on preventing obesity and related complications. When you read that you can lose weight by drinking red wine, that’s a statement that you should interpret cautiously. ![]()
