Document Summary

Diet and nutrition: provides body with nutrients required to produce energy, repair damaged tissue, promote tissue growth and regulate physiological processes. Body requires protein, fats, carbohydrates, vitamins, minerals and water: these are the essential nutrients they must be obtained from food because the body cannot manufacture them. If you consume more calories than expended, they are converted to fat and stored in the body. Examples: milk, meat, fish, poultry, cheese, eggs, soy beans and tofu: foods containing less than 9 essential amino acids = incomplete protein sources. Examples: vegetables, grains, legumes and nuts: proteins make up 10-35% of daily caloric intake, recommended daily intake is 0. 8grams/kg of body weight. When protein intakes are exceeded, it becomes fat for energy storage or burned, which can cause high strain on kidneys. Fats (lipids) provide a concentrated form of energy and give some foods a pleasing taste/texture.
