NUTRITION 15.1 I. NUTRIENTS A. Nutrients- Substances in food that provide energy and materials for your body’s cells. B. Calorie- The amount of energy in food in the form of heat. 1. 1 cal required to raise 1 ml of water 1 degree Celsius. II. 6 ESSENTIAL NUTRIENTS A. Proteins B. Carbohydrates C. Fats D. Vitamins E. Minerals F. Water III. Proteins A. Function: Replacement & repair of body cells B. Subunits: Amino Acids 1. Humans need 20 different amino acids 2. 12 amino acids are made in the body, 8 must be consumed C. Found in meat, fish, eggs, nuts IV. CARBOHYDRATES A. Function: Main source of energy for the body. B. 3 Types of Carbs 1. Simple carbs./sugars found in fruits 2. Complex carbs./starches found in pasta and potatoes IV. CARBOHYDRATES 3. Cellulose found in cell walls of plant cells (lettuce, beans, peas, cereals, etc) a. AKA “fiber” b. Humans cannot digest cellulose c. Helps you poop! V. FATS A. Function: Make up cell membranes, provide energy, absorb vitamins, provide insulation. B. Subunits: Fatty Acids & Glycerol C. Found in oils, meats, etc V. FATS D. Too much fat can lead to heart disease and strokes due to high cholesterol E. 9 cal in each gram of fat 4 cal in each gram of carb. VI. VITAMINS A. Purpose: Growth, metabolism, prevent some diseases B. Needed in small amounts C. Found in fruits, veggies, dairy products, grains, nuts VI. VITAMINS Water Soluble C: Growth, immune system B: Nerves, blood cells, metabolism Fat Soluble A: Growth, Eyes, Skin D: Bones, Teeth K: Wound recover Blood clotting E: Cell membranes VII. MINERALS A. Function: Chemical reactions in your body (muscle movement, digestion, etc) B. Found in dairy products, meats, eggs and vegetables VII. MINERALS Mineral Calcium Health Effect . Strong bones & teeth, Muscle contraction, Blood clotting, Nerve Activity Phosphorus Strong bones & teeth, Muscle contraction, Stores energy VII. MINERALS Mineral Health Effect Potassium Water balance in cells, Nerve impulses, Muscle contraction Sodium Nerve impulses, Water balance in cells . VII. MINERALS Mineral Health Effect Iron Oxygen transport in bloodstream Iodine Thyroid (growth) activity, Metabolism . VIII. WATER A. WATER IS CRUCIAL!!! 1. You can live weeks without food, but only days without water 2. Water is in your blood, cells, tissues—everywhere! 3. Water makes up 60% of your body weight! VIII. WATER B. Water is constantly lost through sweat, exhaling, etc. C. Water homeostasis (internal balance) is maintained because you get thirsty which causes you to drink more water. I.
