Nutrient composition of grains

Grains contain a wide range of nutrients, including carbohydrate, dietary fibre, protein, unsaturated fat, vitamins and minerals, as well as non-nutrients, such as antioxidants and phytoestrogens.

The nutrient content of grains is affected by many factors, including grain variety (genetic factors), growing location (agronomic conditions) and the season (environmental factors). For instance, the selenium content of grains varies with the selenium content of the soil. But these small differences in the nutrient content of different grains are insignificant in terms of the total diet.
