The consumption of dry mature beans was found to lower the risk of a first nonfatal heart attack by 38% in a Costa Rican study. Participants who consumed less than one 1/3 cup cup serving of cooked beans per day did not realize any reduction in risk, and consuming more than one serving per day was not associated with any further reduction of risk, even after confounding factors were considered.
PositiveTip: Simple things like eating one serving of beans per day have the potential to yield big benefits.
