Can Chocolate Lower Your Risk for Stroke?

Swedish Study Suggests Milk Chocolate May Help Your Health
WebMD Health News
Reviewed by Louise Chang, MD

Aug. 29, 2012 -- New research provides another helping of sweet news for chocolate lovers.

Men who eat a moderate amount of chocolate each week may be less likely to have a stroke, compared to men who don’t eat any chocolate.

Most studies suggest that health benefits come mainly from dark chocolate, but the new research seems to extend these perks to milk chocolate. The study took place in Sweden, where about 90% of the chocolate is milk chocolate.

Chocolate contains heart-healthy antioxidants called flavonoids, which may be responsible for some of its health benefits. Other studies have shown that eating a moderate amount of dark chocolate may protect against heart disease and also help with memory.

The new findings appear in Neurology.

Sweet Details

The study included more than 37,000 Swedish men aged 45 to 79 who filled out questionnaires about the foods they ate, including chocolate. During a 10-year period, there were 1,995 cases of stroke.

The men who reported eating the largest amount of chocolate, or about one-third of a cup of chocolate chips per week, were 17% less likely to have a stroke compared to those who ate the least.

The researchers also analyzed the combined findings of five studies (including their own) that had a total of 4,260 cases of stroke. People who ate the most chocolate were 19% less likely to have a stroke compared to their counterparts who ate the least chocolate.

One caveat: As with most studies done on chocolate's benefits, the findings are a link, not cause and effect.

Dark Chocolate vs. Milk Chocolate

Suzanne Steinbaum, DO, says that there may be something different about milk chocolate from Sweden compared to the U.S. She is a cardiologist at Lenox Hill Hospital in New York.

“Is ours more processed? “she asks. “In the U.S., I still recommend dark chocolate, as that is where all the research points. Chocolate could be beneficial for your heart and brain and may hit your sweet spot, too.”

There are things we know we can do today to lower risk of stroke, Caron Rockman, MD, says. She is an associate professor of surgery at New York University Langone Medical Center in New York City.
