Diet and nutrition: an area in which you have increased control, provides body w/ nutrients required to produce energy, repair damaged tissue, promote tissue growth, regulate physiological processes. Nutrition = the science of food and how the body uses it in health and disease. Worldwide, 45% of childhood deaths, and 11% of diseases are attributable to undernutrition. Kilocalories = a measure of energy content in food; 1 kilocalorie represents the amount of heat needed to raise the temperature of 1 litre of water by 1 degree celsius; commonly referred to as a calorie. Choosing a healthy diet involves: knowing which nutrients are necessary and in which amounts, translating those requirements into a diet consisting of foods you enjoy and that are available/affordable. Macronutrients: alcohol = 7 calories/gram (but isn"t an essential nutrient, obviously) ** calorie intake > energy needs = converted to fat and stored in the body.
