Document Summary

Diet and heart disease (oats and soluble fibre 69-73) Consuming oats regularly can lower blood cholesterol, reduce high blood pressure, keep our arteries healthy and help control diabetes. Oat bran, the outer covering of the grain, is an excellent source of soluble fibre, which had the ability to reduce cholesterol (according to studies) Beta-glucan absorbs water in the intestine and traps cholesterol and bile acids from food. Since bile acids are made in the body from cholesterol, their removing from the digestive tract forces more to be synthesized. Thus a depletion of cholesterol is found in the blood. To reduce blood cholesterol by 5%, one needs to eat 3-4g beta-glucan a day. But induces fullness, bloating and gas: a reduction of 5% can lower the risk of a heart attack by 10% Oats lower blood pressure probably by modifying insulin response. The pancreas secretes insulin, which is needed to allow cells to absorb glucose from the bloodstream after a meal.
