Sugar intake, Glycemic Index, Glycemic Load There has been much study of the relationship between blood sugar and chronic diseases. Sugar and starch cause a surge of glucose into the bloodstream. (Glucose is sugar) The glucose in turn , stimulates the pancreas to make insulin, the hormone that converts glucose to energy. Insulin regulates the metabolism of carbohydrates and fats by promoting the absorption of glucose from the blood to skeletal muscles and fat tissue and by causing fat to be stored rather than used for energy. Insulin also inhibits the production of glucose by the liver Chronically high insulin levels are linked to high blood triglycerides, increased fat deposition, increased tendency for blood to clot, and a more rapid return of hunger after a meal. Eventually, the body may develop a resistance to it's own insulin and lead to type II diabetes. The Glycemic Index (GI) reflects how much sugar and starches are in food. It is a measure of how much blood sugar rises two hours after eating 50 grams of that food. Food with high GI's are typically high in sugar and starches and cause a rapid surge in blood sugar compared to foods with a low GI. A major limitation of GI's is that they don't provide comparisons of foods in the way they are consumed. Glycemic Load (GL) is based on the same concept but takes into account how much food is usually eaten. GL's are viewed as a more realistic measure of foods effect on blood sugar surges. From a health perspective our diets should favor foods with a low GI / or GL. As a general rule the more processed the food, the higher the GI or GL. Strategies for Lowering Glycemic Index or Glycemic Load; *Choose whole grain bread over enriched bread. *Add legumes to salad, soups, and chili. *Add vinaigerrete to your salad, yogurt to your cereal, and lemon juice to vegetables. Acid can slow the blood sugar response. *Opt for low GI/ GL snacks such as dried fruit mixed with nuts, fresh fruit, or yogurt. *Avoid overeating-large portions increase blood sugar *Substitute old fashioned oatmeal for instant oatmeal, and bran flakes for corn flakes. *Choose foods high in fiber. *Engage in physical activities. Exercise inhibits big spikes in blood sugar levels. | Do Now: Two in a Row Mile Run Learning Targets: We will debate that the greatest nutrition challenge for Americans may not be to reduce fat intake or cut back on sodium.
