Slowly Digested Carbohydrates

A study from Switzerland showed that while refined carbohydrates are absorbed in the upper intestinal tract to increase risk for obesity and diabetes, slowly digested or non-absorbable carbohydrates that are absorbed in the colon help to lower cholesterol and to prevent heart attacks (American Journal of Clinical Nutrition, 2000, Vol 72, Iss 6, pp 1461-1468). .You should not try to avoid all carbohydrates if you are trying to lose weight. This study and many others show that you should avoid only the carbohydrates that cause a high rise in blood sugar after you eat them. These refined carbohydrates call out insulin to make you hungry. Carbohydrates are single sugars and chains of sugars. Only single sugars can be absorbed. Carbohydrates that can be easily broken down to single sugars are absorbed very rapidly to cause a high rise in blood sugar, which increases your risk for obesity, heart attacks, diabetes, and strokes.

Other types of carbohydrates include fiber and nonabsorbable starches that are not absorbed in the upper intestinal tract, so they pass to the colon where bacteria ferment them into fatty acids that can be absorbed. These fatty acids help to heal the lining of the colon and help to prevent colon cancer. They are absorbed into the bloodstream from the colon and travel to the liver where they help to prevent heart attacks by blocking the synthesis of cholesterol. You want to increase your intake of fiber and nonabsorbable starches found in whole grains, beans, seeds, nuts and many vegetables. Limit your intake of refined carbohydrates including sugar-added foods, fruit juices, bakery products and pastas.
