There is a lot of research coming out showing that diets high in whole grains can lead to lower rates of obesity, heart disease and cancer. For something to be whole grain, it must use the entire grain, not just the flour like most breads do today.
Simply switching to breads that list "whole wheat flour" as their first ingredient can have a major impact on your health. Also consider switching to whole wheat pasta.
Whole grains are what people survived on for thousands of years. It only makes sense that the human body would require them for basic health.
