Whole grains can certainly make for a whole heart. They're packed with fiber, other nutrients, vitamins and minerals. In fact, not only are whole grains, such as oatmeal, great for your heart, but they also can help keep you regular (digestively speaking) and may prevent some cancers, according to WebMD.
Much of whole grains' heart-disease fighting capability comes from soluble fiber. Soluble fiber binds to bile acid. Your body uses bile acid in fat digestion to make cholesterol.
Since our bodies don't digest fiber, that bile acid gets carried out of our bodies as waste. Without that source of bile acid, our bodies turn more cholesterol into bile acids -- thus leading to less heart-disease-contributing cholesterol in our bodies.
