Dr KC Hayes is Prof. Emeritus of Biology (in Nutrition) and has been studying the effect of dietary fat and oils on lipoprotein metabolism for 35 years, as a follow up to his initial training in Nutritional Pathology. His specific interest has been in cardiovascular disease, and most recently as affected by diabetes and obesity. His main focus has been on the relationship between individual fatty acids as they relate to blood cholesterol and trigylceride transport. In recent years he has developed special fat blends for commercial application that take these concepts to heart (so to speak).
