So, what can you eat? Lots of stuff! Make lean protein choices, such as lean beef, skinless poultry and fish and vary your diet. Eat whole grains and choose low-fat or fat-free dairy foods. The holidays are a great time of year to start thinking about healthier habits. If you do snack, make it a nutritious choice—such as cheese, yogurt, fruits, and vegetables—for your overall health and the health of your teeth.
