Studies also show that beta-glucan has beneficial effects in diabetes as well. Type 2 diabetics who ate foods high in this type of oat fiber such as oatmeal or oat bran experienced much lower rises in blood sugar compared to those who were ate processed foods. Starting out your day with oats may make it easier to keep blood sugar levels under control the rest of the day, especially when the rest of your day is also includes other whole foods that are rich in fiber.

More recently, researchers from the Human Nutrition Research Center on Aging, Tufts University, Boston, report that oats may have another heart protective quality.   Their findings were reported in The Journal of Nutrition, June 2007, and indicate that oats contain unique antioxidant compounds called avenanthramides. These special antioxidant compounds help prevent free radicals from damaging LDL cholesterol thereby reducing the risk of cardiovascular disease. 

In another study also conducted at Tufts and published in the journal Atherosclerosis, researchers exposed human arterial wall cells to purified avenenthramides from oats for 24 hours, and found that these oat phenols significantly suppressed the production of several types of molecules which cause arteries to become clogged.
