HOT TIP: From Shape Magazine: Did you know that bread is the number one food that contributes the most calories in the American diet? The number two source is cookies and cakes. Most bread is made from enriched flour and high-fructose corn syrup. The best bread to is one labeled “100% whole wheat” or “100% whole grain.” Otherwise, you are just eating different forms of sugar or unhealthy grains. Look for only whole grain flour breads.
