When we speak of grains many foods come to mind such as breads, cereals, crackers, pasta and rice. Whole grains are a good source of complex carbohydrate, dietary fiber, plant protein, vitamins, minerals and phytochemicals. Recent research indicates that the entire grain, not just the fiber provides health benefits. As an example, whole grain wheat and oats are comprised of hundreds of phytochemicals, such as phytoestrogens, antioxidants, phenols, as well as, vitamins and minerals. It is thought that these compounds may act together to play important roles in disease prevention. They have been studied for their ability to reduce risk of cancer, heart disease, constipation, diabetes and obesity. Grains form the base of the food pyramid and represent the food group that we need most abundantly in our diets.
