Regular Bowel Movements
The fiber in whole grains provides the “roughage” that is needed to maintain healthy bowel movements. A lack of fiber in the diet can lead to constipation. Keeping things moving through the intestines is very important in order for the body to get rid of waste.

Cardiovascular Health
Whole grain fiber is also essential in the prevention of heart disease and other cardiovascular problems. Additionally, many whole grains contain antioxidants which can help to scavenge free radicals that may lead to heart disease.

Blood Glucose Levels
When glucose levels in the blood are high, it may lead to type 2 diabetes. Whole grains slow down the digestive process, which keeps blood glucose levels lower.

Weight Loss
Maintaining lower blood sugar levels is one of the most effective ways to get rid of excess fat. Also, high fiber foods keep you feeling fuller longer, which will prevent you from overeating.
