Barley is one of the first cereal crops ever domesticated by humankind. Barley is considered to be one of the most nutritious cereals and is therefore consumed as a popular health food. Its nutritional content primarily consists of carbohydrates, dietary fiber, fat and protein, as well as vitamins, including thiamine, riboflavin, niacin, pantothenic acid, folate, vitamin B6 and C. Calcium, iron, magnesium, phosphorus, potassium and zinc are the minerals which are also included in barley.
