When eaten as the whole grain, wheat is a source of multiple nutrients and dietary fiber. Wheat is an important source of carbohydrates. In 100 grams, wheat provides 327 kilocalories and is a rich source (20% or more of the Daily Value, DV) of multiple essential nutrients, such as protein, dietary fiber, manganese, phosphorus, and niacin (table). Several B vitamins and other dietary minerals are in significant content. Wheat is 13% water, 71% carbohydrates, and 1.5% fat. Its 13% protein content is mostly gluten (75-80% of the protein in wheat). Though they contain adequate amounts of the other essential amino acids, at least for adults, wheat proteins are deficient in the essential amino acid, lysine. Whole Wheat has a very long shelf life and can be kept in a cool, dry place for years. They can be ground down to make flour or boiled as is and used as an addition to salads, or as cereal, etc.
