Whole grains are great for health because they contain B vitamins (e.g. niacin, thiamin, riboflavin), plenty of fiber, and important minerals.
HEALTH BENEFITS OF WHOLE GRAINS:
1) reduces the risk of heart disease and blood cholesterol-- from the fiber found in whole grains
2) also helps maintain your weight- the fiber in whole grains makes you feel full without having to each as much and without giving you as many calories as other foods
if you want more:
3) help digestion- once again it's the fiber that helps reduce constipation
4) helps regulate blood sugar- these whole grains help prevent you blood from abruptly increasing in blood sugar ("glucose") levels, thus reducing the risk of developing Type 2 diabetes
