AphrodisiacRomantic lore commonly identifies chocolate as an aphrodisiac. The reputed aphrodisiac qualities of chocolate are most often associated with the simple sensual pleasure of its consumption. Although there is no proof that chocolate is indeed an aphrodisiac, a gift of chocolate is a familiar courtship ritual.
Muscle recoveryA study from James Madison University, presented at the American College of Sports Medicine annual meeting, showed that post-exercise consumption of lowfat chocolate milk provides equal or possibly superior muscle recovery compared to a high-carbohydrate recovery beverage with the same amount of calories. Athletes consuming chocolate milk had significantly lower levels of creatine kinase, an indicator of muscle damage, compared to drinkers of carbohydrate beverage. Sweating causes loss of fluid and also important minerals, including calcium, potassium and magnesium. The 2-hour window after exercise is an important, but often neglected opportunity to recover.
