We are often more concerned with the taste of food than with its nutritional value when choosing from a menu or when selecting food to prepare. Knowing about nutrition is important, however, because food provides us with energy and the building blocks necessary to synthesize new molecules. What happens if we don't obtain enough vitamins, or if we eat too much sugar and fats? Health claims about foods and food supplements bombard us every day. Which ones are ridiculous, and which ones have merit? A basic understanding of nutrition can help us to answer these and other questions so that we can develop a healthy diet.
This chapter explains nutrition (p. 932), metabolism (p. 940), carbohydrate metabolism (p. 942), lipid metabolism (p. 949), protein metabolism (p. 950), interconversion of nutrientmolecules (p. 952), metabolic states (p. 953), metabolic rate (p. 955), and body temperature regulation (p. 956).
