Resveratrol is a polyphenolic compound found in a variety of foods and some beverages. Polyphenolics add color and taste to foods, and they play a role in various chemical reactions in the body. Resveratrol has antioxidant properties. Antioxidants neutralize free radicals, which are byproducts of digestion that can cause damage to cells in the body. While resveratrol may show promise in managing many chronic conditions, seek the advice of a physician before consuming resveratrol or making any changes to an ongoing treatment program.
Heart Disease
There is some indication that resveratrol may help lower the risk of heart disease by preventing damage to blood vessels, preventing blood clots and reducing low density lipoprotein or LDL cholesterol, which is considered the bad kind because it is stored in the body. In addition, resveratrol may also help control inflammation in blood vessels. Since studies on the benefits of resveratrol for heart disease have only been performed in animals, there is no recommended amount to take to reduce the risk of heart disease, according to MayoClinic.com.
Cancer
According to the National Cancer Institute, consuming polyphenols such as resveratrol may help inhibit the development of some forms of cancer. The antioxidant properties in resveratrol may inhibit the actions of the free radicals that cause cellular damage, which contributes to the development of cancer. Resveratrol may work by reducing inflammation and slowing tumor growth. As with heart disease, the majority of studies have been done in animals, so there is no general recommended intake for humans in regard to cancer prevention. However, the NCI states that men who consume four or more 4 oz. glasses of red wine per week, have a 60 percent lower incidence of the more aggressive types of prostate cancer.
Obesity and Diabetes
While much more research is still needed, resveratrol may help in the weight-loss battle and in managing diabetes, states the National Center for Biotechnology Information. Testing in animals demonstrated that this compound may reduce body fat in obese animals by influencing enzyme activity. Resveratrol may also help control insulin secretion, which can keep blood sugar levels in control in those with diabetics.
Sources
Resveratrol is found in red wine, red and purple grape juices, peanuts, blueberries and cranberries. However the amount found in foods and beverages can vary widely and since the body metabolizes resveratrol quickly, it is unknown how much is needed to receive benefits, states the Linus Pauling Institute. When it comes to consuming wine, men should limit intake to no more than two glasses of wine a day, and women should limit intake to no more than one glass of wine per day. In addition, its safety when taken in supplement form has not been fully studied.
