If you're an average gym-goer and looking for a good choice of recovery beverage a study on nutrition has an unlikely to choice. The study by Indiana University published in the "International Journal of Sports Nutrition and Metabolism" says before reaching for protein smoothies or muscle-building drinks your wisest option is chocolate milk. It seems that for the average workout regular ol' chocolate milk has the right amount of protein, carbs and sugar unlike high-priced store-bought energy drinks. The study also discovered chocolate milk has vitamins and nutrients not typically found in commercially-produced energy drinks.
