  9. Carbohydrates • The body’s main energy source. • Complex • Simple (end in -ose) glucose, sucrose, fructose

  10. Carbohydrates • Careful . . . “white” grain products have a high glycemic index • They make blood sugar rise almost as fast as simple sugars • Ex: white rice, white bread, white pasta

  12. Proteins • Needed to build, repair, and maintain body cells and tissues

  13. Fats/Oils • Insulate the body • Provide stored energy • Cushion body organs

  14. Fats • Solid at room temperature • Usually animal-based (butter, lard) • Not healthful • “Trans-fats” - plant oils chemically altered to be solid at room temperature - REALLY bad for you! (look for “partially hydrogenated” in the label)

  15. Oils • Liquid at room temperature • Plant based (olive, canola, nut oils) • Healthy! • “MUFA” - mono unsaturated fatty acids

  16. Vitamins • Control body functions • Help immune system • Help the body to grow

  17. Vitamin examples • Vitamin C - in citrus fruits, needed for healing, healthy gums • Vitamin A - in carrots, other orange-colored vegetables, needed for good vision, healthy skin

  18. Minerals • Needed for healthy bones, teeth, and blood

  19. Water • The most common nutrient • 60% of your body is water • Carries nutrients through the body • Helps digestion • Keeps the body from overheating • Lubricates the body joints • Removes waste from the body

  20. Mineral examples • Calcium - in dairy products, dark green vegetables, needed for bone and teeth growth and strength • Iron - in meat and beans, needed for proper blood development and carrying oxygen. • Sodium - added to MANY foods, Americans get too much of this mineral - maximum 2300 mg per day recommended.
