What is the difference between oats and wheat?

Oats are a source of soluble fiber while wheat is a source of insoluble fiber. Wheat is a better source of B vitamins than oats. However, oats help to promote healthy bowel function.

According to Dukan Diet Primer, wheat bran contains cancer-preventing properties that are not as high in oat bran. The soluble fiber in oats is a gel-like substance that binds to cholesterol in the body and eliminates the cholesterol through the stool. Soluble fiber is also known as beta-glucan, which has been thought to lower the risk of coronary heart disease. Wheat also contains gluten, which is harmful to those who suffer from celiac disease.
