Like other studies that passively follow populations, this one couldn’t prove that particular fruits led to less heart disease, but the researchers said it adds to the limited knowledge base about heart disease risk in younger women, who are much less likely than women over age 60 to develop heart disease.

“Our data suggest a potential role for flavonoids, specifically anthocyanins, in reducing risk,” wrote the study authors. And unlike alcohol, which is associated with health risks as well as benefits, consuming berries and other dark-colored fruit on a regular basis can only be a win-win for women.

That said, the decrease in risk is a small one, considering that heart attacks are very uncommon in women under age 60. It’s also not certain how much berries and other dark colored fruits play a role in reducing heart disease risk in men and older women.
