Instant Oats Instant oatmeal is a delicious dish for breakfast, which also helps you in reducing your hunger. It is largely because of the fiber in oats that forms gels to fill up. That gel in turn delays the emptying of your stomach so that you don't feel hungry quickly. Not only they are rich in fiber, they also contain various minerals and phytonutrients. Researches have indicated that intake of oats cuts your risk of high blood pressure and type 2 diabetes. Prefer to choose oatmeal that contains whole oats and low sodium.
