A new study suggests that eating a small piece of chocolate daily may reduce your risk of heart attack and stroke, report UTMB’s Norbert Herzog and David Niesel in this week’s installment of Medical Discovery News. “The people in this study ate the equivalent of a 3.5 ounce square of chocolate every day — that’s the size of two small chocolate bars. The result was a 39-percent lower risk of heart attack or stroke compared to people who ate much less chocolate. … The study followed 19,000 adults for 10 years. The participants received medical checkups when the study began and every two to three years filled out questionnaires about how much and how often they ate chocolate. By the end of the study, researchers found that people who ate the most chocolate, an average of only a quarter ounce a day — that’s less than two Hershey’s kisses — had a 27 percent lower risk of heart attack. And they had a 48 percent lower risk of stroke than people who ate the least amount of chocolate.” The program airs locally at 10 a.m. Saturday on KUHF.
