Document Summary
Food as fuel (know for exam, what foods fall in high/low density) Basal metabolic rate (bmr): the total number of calories that your body needs to perform basic, life-sustaining functions. These basal functions include circulation, breathing, cell production, nutrient processing, protein synthesis and ion transport. When energy requirements are met, weight does not change. When ingested calories exceed energy requirements, weight gain occurs. When ingested calories do not meet energy requirements, weight loss occurs. Essential nutrient: cannot be manufactured by the body. Nutrient density: the proportion of essential nutrients to the number of kilocalories. Functional foods: when a biologically active substance is added to food. Fortified foods: when vitamins or minerals are added to food. Genetically modified foods: genes of one organism are mixed with genes of another to produce crops that are more resistant to disease, etc. The main source of energy in the diet. Three types: (1) monosaccharides, (2) disaccharides, (3) polysaccharides.
