Ancient Egyptian Papyri and Sumerian tablets dating back to 2200 BC detail the medicinal role of wine, making it the world's oldest documented man-made medicine. Wine continued to play a major role in medicine until the late 19th and early 20th century, when changing opinions and medical research on alcohol and alcoholism cast doubt on the role of wine as part of a healthy lifestyle and diet.
In the late 20th and early 21st century, fueled in part by public interest in reports by the U.S.news broadcast 60 Minutes on the so-called "French Paradox", the medical establishment began to re-evaluate the role of moderate wine consumption in health. Studies have since shown positive benefits of the phenolic compound resveratrol with continued research attempting to better understand its functions in wine and the body.
