Document Summary
Used for energy, growth, maintenance, and repair of tissue. Essential nutrients specific biological functions have been identified: body cannot make enough of them to meet biological needs, examples: vitamin c. Nonessential nutrients: body can produce sufficient amounts. Macronutrients nutrients required in relatively large amounts: carbs, proteins, lipids, water. Micronutrients nutrients required in smaller amounts: vitamins, minerals. Energy from nutrients: measured in kilocalories (kcal, body transfers energy found in food into atp (form of energy body uses) Carbohydrates (cho: carbon, oxygen, hydrogen, 4kcal per gram, body prefers to use carbs for energy, fruits, veggies, grains, seeds. Proteins: carbon, oxygen, hydrogen, nitrogen, 4kcal per gram, dairy, meat, legumes, used for growth, repair, and maintenance. Repair muscles during growth periods, such as pregnancy/working out. Lipids: carbon, oxygen, hydrogen, 9kcal per gram, stored energy. Minerals: sodium, potassium, chromium, sulfur, fluorine, calcium, etc, need in very small amounts, they are inorganic substances, help with fluid regulation, bone structure, muscle movement, nerve function, energy production.
