Wholegrains are a rich source of fibre, B vitamins, and essential minerals such as iron, magnesium, and zinc. Regularly including wholegrains in the diet has been linked to a lower risk of heart disease, type 2 diabetes, and certain cancers. Unlike refined grains, wholegrains retain all parts of the grain – the bran, germ, and endosperm – providing a slower release of energy and supporting digestive health by promoting a healthy gut microbiome.
