A recent Harvard study will please chocoholics...sort of. It seems that eating a small amount of high-quality dark chocolate one to three times a month may help stave off heart failure in women. But, eating too much "good" chocolate takes away the protective effect and isn't recommended. This study, reported in the August 17th issue of Circulation: Heart Failure, cites that the benefits are probably caused by flavonoids, or antioxidants, that can smooth heart function. But, of course, we all know about the calories. The motto: all things in moderation.
