2. Avoid - or at least limit - your intake of refined-flour baked goods, including non-whole-grain breads, bagels, doughnuts, cupcakes, brownies, cakes, etc. Also, throw out the processed, high-sugar breakfast cereals - stick to whole-grain cereals and oatmeal.
3. Buy a variety of fresh fruits and veggies and begin to include at least 1 or 2 servings with each meal. Also, avoid getting hungry (and overeating) by snacking on fruit or cut-up veggies throughout the day - a single large apple can easily curb hunger.
4. Try to eat a serving of leafy green vegetables at least twice a day. Also, eat a variety of other colorful vegetables as often as possible.
5. Use nuts and seeds as healthy, portable snacks you can carry anywhere. Also, they can be used to add flavor and 'texture' to many different foods (especially salads).
6. Eat a serving of beans or legumes at least 1-2 times per day. The dozens of different types of beans and peas can be used in hundreds of healthy recipes. Also, consider buying or making bean sprouts - they are considered to be some of the most nutritionally 'powerful' foods available!
7. If you buy grain products - including breads, cereals, crackers, pastas, etc. - always choose whole-grain options. Just make sure that 'whole-grain' is the first word in the ingredients list and you'll be fine.
8. When possible, always choose organic foods.
