  7. 7. Fats and Oils <ul><li>Fats are the storage form of energy in our bodies. </li></ul><ul><li>They are stored around our organs and under our skin for protection and warmth. </li></ul><ul><li>Fats are the bodies energy source secondary to Carb’s. </li></ul><ul><li>Fats are an incredible rich energy source. Providing nearly 10 times more energy than other nutrients. </li></ul><ul><li> </li></ul>
  8. 8. Fats and Oils <ul><li>There are “good” (unsaturated) fats and “bad” (saturated) fats. </li></ul><ul><li>Saturated tend to come from animal products and unsaturated from plants. </li></ul><ul><li>It is important to regularly consume fat in your diet. </li></ul>

Vitamins <ul><li>Vitamins are found in most of the foods we eat. </li></ul><ul><li>Keep metabolism regular and help release energy from digested foods. </li></ul><ul><li>Allow the body to process carbohydrates, fats, and proteins. </li></ul><ul><li>Some vitamins also help the body produce blood cells, hormones, chemicals and genetic material. </li></ul>
  12. 12. VITAMINS <ul><li>Help prevent diseases. </li></ul><ul><li>Vitamins also help protect the body from heart disease and cancer. </li></ul><ul><li>There are 13 well-identified vitamins. </li></ul>

  15. 15. Minerals <ul><li>Minerals are inorganic substances, this means we don’t get them from plants or animals, minerals come from the earth </li></ul><ul><li>14 minerals have been shown to be critical to human health. </li></ul>
