How to improve Nutrition?

To Improve Nutrition:

1. Buy whole foods -- whether canned, frozen, or fresh from the farm -- and use them in place of processed foods whenever possible.
2. Reject foods and drinks made with corn syrup, a calorie-dense, nutritionally empty sweetener that many believe is worse for the body than sugar, says Katz.
3. Start each dinner with a mixed green salad. Not only will it help reduce your appetite for more caloric foods, but it also will automatically add veggies to your meal.
