Studies and research

A number of studies have been issued in regard to chocolate milk nutrition. A 2005 study by the New York City Department of Education found that by removing whole milk and replacing it with low-fat or fat-free chocolate milk, students were served an estimated 5,960 fewer calories and 619 fewer grams of fat per year. However, more recent studies show that fat-free and low-fat milk may actually increase body fat and contribute to obesity. Whole milk may in fact be healthier for obese children than low-fat or non-fat milk. An April 2007 study from

concluded similar results in male soccer players, discovering that there was an increase in time to fatigue when chocolate milk was consumed. The Kean University study also viewed chocolate milk's effects on female soccer players undergoing morning and afternoon practices during preseason. They were either given the carbohydrate-electrolyte beverage or chocolate milk between morning and afternoon preseason practices. Following every afternoon practice, each athlete completed a shuttle run to fatigue. The study concluded that chocolate milk is just as beneficial as the carbohydrate-electrolyte beverage in promoting recovery in women.

, thus preventing the calcium from being absorbed in the intestine. However, it is present in small enough amounts that the effect on calcium absorption is negligible (2–3%). As chocolate contains relatively small amounts of oxalate, it is unclear to what extent chocolate consumption affects healthy people with calcium-rich diets. In a 2008 study, participants who consumed one or more servings of chocolate on a daily basis had lower bone density and strength than those participants who ate a serving of chocolate six times a week or less. Researchers believe this may be due to oxalate inhibiting calcium absorption – but it could also be due to sugar content in chocolate, which may increase calcium excretion. It is clear, however, that consuming foods high in oxalate – and in turn their effect on calcium absorption – is a more significant concern for people with oxalate
