Nutritional

Nutrition, more specifically nutritional science, is the science that studies the physiological process of nutrition, interpreting the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.The diet of an organism is what it eats, which is largely determined by the availability and palatability of foods. For humans, a healthy diet includes preparation of food and storage methods that preserve nutrients from oxidation, heat or leaching, and that reduces risk of foodborne illnesses. [Source: Wikipedia ]
