Three Drinks Linked to Longevity in the World's Blue Zones

In a recent video, longevity expert Dan Buettner identified three drinks that appear frequently in the diets of people living to 100 in blue-zone areas like Sardinia, Italy, and Okinawa, Japan. He placed purified water at the top, citing that locals consume six to seven glasses daily, which may help maintain blood pressure, keep blood thin, and ensure proper hydration, a factor linked by NIH research to healthier aging.

The second recommendation is black coffee—one to two cups a day, finished by noon—because its antioxidants and polyphenols have been associated with reduced rates of type 2 diabetes and Parkinson's disease. The third beverage is a small amount of red wine enjoyed with meals; while Buettner notes its controversial status, he points to compounds such as resveratrol that could support cardiovascular health, though he also warns of alcohol-related risks. Experts stress that the benefits depend on moderate consumption and that individuals with health conditions should seek professional advice before changing their diet.
