One of the major factors that contribute to heart diseases is high blood cholesterol. Many studies have shown that the soluble fiber present in oats called Beta-glucan plays a vital role in reducing both total cholesterol & LDL level in the blood.

Stabilizes blood sugar

Type-2-diabetes is a disease characterized by significantly elevated blood sugars which results from decreased sensitivity to the hormone insulin.

Oats have a low glycemic index. Foods that are digested quickly can cause the blood sugar to spike, making it difficult to manage the blood sugar level. But oats, due to their high fiber content are digested slowly .This helps regulate the sugar level in the blood.

Oatmeal makes the contents of the stomach thicker, thereby delaying the emptying of the stomach and absorption of glucose in the blood, thus preventing sharp rise in blood sugar immediately after eating.

However, not all kinds of oats are good. Stay away from the flavored or instant varieties which are loaded with sugar which do not offer the benefit you are looking for.

Stimulates growth of useful bacteria in the gut.

The lower part of the large intestine has been identified as a key organ affecting general health. It is the store house of many beneficial bacteria that are essential for the normal functioning of the body.

The growth and metabolism of many of these bacterial species inhabiting the colon depends primarily upon the substrates available to them, most of which come from the diet. These are called the 'prebiotics' which are basically non-digestible ingredients present in the cereal matrix that selectively stimulate the growth and activities of some bacteria.

In case of oats, it’s the fiber beta-glucan which makes it a good substrate for the growth of bacteria found in the colon. The end product of this prebiotic fermentation is production of short-chain fatty acids that serve as nutrients for the mucosal cells.

Other benefits: Another major reason why oats are widely preferred is - Gluten is a protein found primarily in wheat, barley and rye & is said to be an allergen. But oats are gluten free and hence considered safe for people who are intolerant to wheat.

People with gluten intolerance develop digestive problems such as gas, abdominal pain and diarrhea. For such people, oats are the best choice!!
