How Many calories in one cup of plain yogurt?

Plain yogurt contains around ten to fourteen grams of protein per eight ounces, which amounts to twenty percent of the daily protein requirement for most persons. In fact, eight ounces of yogurt that contains live and active cultures, contains 20 percent more protein than the same volume of milk (10 grams versus 8 grams). Besides being a rich source of proteins, the culturing of the milk proteins during fermentation makes these proteins easier to digest. For this reason, the proteins in yogurt are often called "predigested."
