Avena sativa L, commonly referred to as oats, occupies a prominent position among cultivated oats and is thought to have originated in Asia, resembling wheat as an annual grass. Oats are notably abundant in soluble dietary fiber, specifically β-glucan, renowned for its exceptional functional and nutritional properties. Acknowledged as the primary active component of oats, β-glucan is celebrated for its cholesterol-lowering and antidiabetic effects.
β-glucan exhibits outstanding functional and nutritional characteristics, showcasing high viscosities even at relatively low concentrations. The health benefits associated with β-glucan fiber include a reduction in blood glucose and insulin response, the promotion of beneficial digestive bacteria growth, and the regulation of type 2 diabetes. Owing to its fiber content, oatmeal is beneficial in lowering "bad" LDL cholesterol, stabilizing blood sugar levels, and alleviating high blood pressure—significant factors in minimizing the risk of cardiovascular disease.
Numerous studies have confirmed the effectiveness of β-glucan fiber in oats, demonstrating its capacity to significantly lower both total and LDL (bad) cholesterol levels. Moreover, β-glucan may induce the release of cholesterol-rich bile, consequently reducing circulating cholesterol levels in the bloodstream.
Incorporating 3 grams of soluble fiber from oatmeal into a daily diet low in saturated fat and cholesterol may decrease the risk of heart disease. Notably, each serving of this cereal contains 2 grams of soluble fiber.
