Bagel with Peanut Butter

Watch out for low-fat claims. Low-fat does not necessarily mean low-calorie. The label can give you a sense of false security, setting off over-eating. Treat low-fat foods like any others, and enjoy them in moderation. And remember, in some cases, such as peanut butter, the reduced-fat version is not necessarily healthier.
