Among the healthy nutrients that are present in oat bran include protein, dietary fiber, thiamine, magnesium, phosphorous, manganese and selenium. The dietary fiber that is contained in oat bran, as well as in oats and oatmeal is called beta glucan, which studies show to be very effective in lowering cholesterol levels. These studies show that eating just 3 grams of dietary fiber in oats daily can reduce cholesterol levels to as much as 23 percent.
