1. Sources
   1. Foods of plant origin
      1. Photosynthesis
         1. Converts Carbon Dioxide and Water to glucose and oxygen
      2. Carbo Foods rich in Vitamins, Minerals, phytochems, and fiber
         1. Grains
         2. Vegetables
         3. Dairy Foods
   2. Lactose in Milk
2. Necessary
   1. Essential to Human Life
   2. Glucose Homeostasis essential for proper cell function
   3. Brain/Nervous System & Red Blood Cells
      1. Lack = Dizziness
      2. Blood Glucose
   4. Glucose needed to burn fat
3. Lack Of
   1. Production of Ketones (Ketosis) = prolonged production results in acid/base imbalance
   2. 2 slices of bread (50-100 g) sufficient to Prevent Ketosis

5. Physiology
   1. Efficient, Cheap Body Fuel
   2. Some glucose stored in liver and muscle - See Note
   3. Sugars and Carbos structurally important to some Proteins and and membranes of the cell
   4. More carbos eaten than needed, glucose converted and stored as fat
