Terminology

  • Nutrition: The science of food and how the body uses it in health and disease
  • Essential nutrients: Substances the body must get from foods because it cannot manufacture at all, or fast enough to meet needs.
  • Macronutrient: An essential nutrient required in relatively large amounts.
  • Micronutrient: An essential nutrient required in minute amounts.
  • Kilocalorie: A measure of energy content in food; 1 kilocalorie represents the amount of energy needed to raise 1 liter of water 1°C
  • Carbohydrates: The word carbohydrate literally means “hydrated carbon,” or carbon with water. Can be either simple or complex.
  • Fats: Lipids consist of fatty acids, triglycerides, phospholipids, and sterols (cholesterol). Can be either Saturated or Unsaturated.
  • Proteins: Protein is another major macronutrient that, like carbohydrates, consists of small repeating units. But instead of sugars, proteins are made up of amino acids. Can be either complete or incomplete.
  • Soluble Fiber: Fiber that is found to lower cholesterol levels.
  • Insoluble Fiber: Fiber that binds to water and allows for soft fecal matter
  • Vitamins: Organic substances found in food that can either be fat or water soluble.
  • Minerals: Inorganic substances found in food or spices.
