Proper nutrition is fundamental to good health. You are, after all, what you eat. We apply the principles of nutrition to designing healthy diets that can help prevent and manage several chronic diseases like diabetes, heart disease, stroke, and some cancers. The role of nutrition in maintaining that whole health focus we aim for is much more than the prevention of illness. Health extends beyond the lack of disease. The foods we choose, as in our healthy diet plan, are selected to provide nutrients that are the most essential to physical growth building and development, brain health and development, and stress reduction.
