Increase fiber gradually to avoid gas, bloating and possible bowel obstructions. Drink plenty of fluids. Eating more did not further lower cholesterol. Credited with lowering cholesterol are oats' beta glucans, a soluble gummy fiber. Only whole-grain cereals are high in fiber.
Refined grains have little or none.
Oats also may ward off infections by increasing the intestines' protective mucus barrier against toxins and bacteria, such as E. coli, according to new research by gastroenterologist Stig Bengmark at Lund University in Sweden. Whole-grain cereals may help control weight by making you feel more full. People who eat breakfast, including cereals, take in more nutrients than those who do not, studies show. Whole-grain cereals are naturally rich in selenium, zinc, magnesium and B vitamins. Check the label for sugar content.
