Resveratrol has been making headlines as a heart healthy ingredient in certain foods. Although it is still unclear exactly how and if resveratrol benefits the heart, some research is promising. According to the Mayo Clinic, resveratrol's ability to reduce inflammation and blood clotting is hoped to minimize heart disease. Knowing which foods contain resveratrol will help you incorporate it into your diet and begin a journey to a healthier heart.

Grape Juice and Red Wine
According to The Linus Pauling Institute at Oregon State University, a 5-oz. glass of red grape juice contains .17 to 1.3mg of resveratrol, whereas grape juice converted to red wine contains .3 to 1.07mg. The primary contributor of resveratrol in grapes is the skin and stems, which are essential to the production of red wine.
A 5-oz. glass of white wine contains .01 to .27mg of resveratrol. The production of white wine does not involve the use of grape stems and skins, which is why its resveratrol content is lower.
A 5-oz. glass of rosé wine contains .06 to .53mg of resveratrol. Rosé wine gets its slight pink color from abbreviated contact with the stems and skins of the grapes.
One cup of fresh red grapes contains .24 to 1.25mg of resveratrol.
One cup of raw peanuts contains .01 to .26mg of resveratrol, 1 cup of boiled peanuts contains .32 to 1.28mg and 1 cup of peanut butter contains .034 to .13mg.
Other Food Sources
Cranberries, blueberries and pomegranates are also purported to contain resveratrol, but research on these fruits is minimal compared to that of grapes, wine and peanuts. Early research suggests that these foods contain resveratrol in lesser amounts.
