Digestion

  1. 1. Mechanical Versus Chemical <ul><li>Mechanical: Breakdown by physical means </li></ul><ul><li>Examples: Chewing, swallowing, fluid breakdown, mashing, grinding. </li></ul><ul><li>Chemical: Breakdown by chemical means </li></ul><ul><li>Examples: Enzymes in saliva, acids in stomach. </li></ul>
  2. 2. Carbohydrates: Long chains of sugars attached together, stored briefly in blood and broken down for energy
  3. 3. Proteins: Long chains of amino acids, stored in muscles.
  4. 4. Fats: Strings of individual fatty acids attached together, stored on top of muscles. <ul><li>Saturated: Maximum amount of hydrogen on fatty acids. </li></ul><ul><li>Examples: Butter and solid fats </li></ul><ul><li>Unsaturated: Multiple places where hydrogen is missing. (Better for you) </li></ul><ul><li>Examples: oils and liquid fats </li></ul>
  5. 5. Enzymes: Chemicals that aid in breaking down carbohydrates, fats and proteins. <ul><li>Order of food breakdown </li></ul><ul><li>Carbohydrates in blood (turned to fat if not used) </li></ul><ul><li>Fat in body </li></ul><ul><li>Proteins (muscle degeneration) </li></ul>Diets, do they work? Which ones?
