Nutrition • Carbohydrates-body’s preferred source of energy or calories. • Ex: Sugar, starches, fiber • Sugar- simplest form of a carbohydrate (glucose) • Starches- breakdown into glucose during digestion. • Fiber- another form of a carbohydrate. Tough stringy part of fruits, vegetables and grains. It can not be digested so it helps move waste through the digestive tract. • 20-30 grams a day

  2. Fats~ Lipids, provide twice the energy as carbohydrates and proteins. • Saturated Fats-animal fat • Unsaturated Fats-vegetable Fat • Fats add flavor to food • Helps satisfy hunger longer • Needed in diet to insulate organs and body • Too much fats leads to weight gain. • 25%-35% per day

  3. Protein~ Vital part of every body cell and made up of chains known as Amino Acids. • Amino acids- basic unit of protein. *Two types of protein* • Complete - food that contains all essential amino acids. • Meat, Poultry, Milk, Yogurt, Eggs • Incomplete- proteins that does not contain all the essential amino acids • Typically come form plants • 50% of body weight in grams per day. • Ex (140lbs = 70 grams protein)

  5. Minerals~ inorganic substances that the body cannot manufacture. • Function :to repair body tissues. Water ~most essential of all nutrients ***The human body is about 60-70 percent water • Vital to every body function • Absorbs nutrients • Eliminates waste • Cools body

  6. Old Food Pyramid

  7. New Food Pyramid

  8. OLD vs. NEW PYRAMID Grains: The old pyramid included “breads, cereal, rice and pasta” as its largest rung on the pyramid; whereas, the new one’s largest category is grains, half of which it says should be whole grains. Fruits and vegetables: The new Pyramid breaks vegetables and fruits into two separate sections and encourages variety. Less meat: The old Pyramid called for 2-3 servings from its protein category (about 6-12 ounces). The new Pyramid calls for a 5.5 ounce serving per day, which includes beans. It also advises against frying. Lighter dairy: The old Pyramid had a section titled “milk, yogurt and cheese.” The new Pyramid calls this section “dairy” and includes the caveat that it should be no-fat or low-fat dairy. Healthier fats: The top of the old Pyramid was “fats, oils and sweets.” The corresponding part of the new Pyramid is called “oils,” and it includes the following guideline: “Limit solid fats such as butter, margarine and lard.” Limiting sugar, sodium, saturated fats and trans fats: The New Food Pyramid advises to choose foods low in added sugar, and keep consumption of saturated fats, trans fats and sodium low.

  9. In addition to food information, the New Pyramid features a person running up the side of the pyramid to emphasis fitness, along with the following advice: Adults should be physically active for at least 30 minutes most days of the week, children for 60 minutes. Sixty to 90 minutes of daily physical activity may be needed to prevent weight gain or sustain weight loss. The most interesting feature of the new Pyramid is that it individualizes its guidelines based on age, sex and level of physical activity.
