Pearl barley is barley grain with the outer husk and some of the bran removed. The figures here describe the raw, uncooked grain. It mainly provides carbohydrate, with some protein and a small amount of fat. Per 100g, it contains 84g of carbohydrate, 7.9g of protein and 1.7g of fat, providing 1535 kJ of energy.

Carbohydrate supplies energy, while protein is needed for the growth and repair of body tissues. Pearl barley contains gluten, so it is not suitable for people with coeliac disease. Cooking causes the grain to absorb water, so the nutrient content by weight differs from these raw figures. Full nutrient figures are in the tables below.
