Milk is the opaque liquid food obtained from the mammary glands of animals and is a source of nutrition used by humans. The ingredients of raw milk differ according to the species it is obtained from on the basis of protein, calcium, saturated fat and Vitamin C. Cow’s milk is used extensively as a drink by human beings and used to manufacture many products like chocolates, ice-creams, yogurt, butter etc.
Buttermilk is obtained when the fat has been taken out from the milk to make butter. Buttermilk is considerably lower in calories and fat content but high in calcium, Vitamin B12 and potassium than regular milk. One cup of buttermilk may contain up to 99 calories while milk may contain up to 157 calories.
