We eat mostly what's available at home. That's why it's important to control the supply lines — the foods that you serve for meals and have on hand for snacks.

Follow these basic guidelines:

Work fruits and vegetables into the daily routine, aiming for the goal of at least five servings a day. Be sure you serve fruit or vegetables at every meal.

Choose healthy snacks by keeping fruits and vegetables on hand and ready to eat. Other good snacks include low-fat yogurt, peanut butter and celery, or whole-grain crackers and cheese. Serve lean meats and other good sources of protein, such as fish, eggs, beans, and nuts.

Choose whole-grain breads and cereals so you get more fiber.

Limit fat intake by avoiding deep-fried foods and choosing healthier cooking methods, such as broiling, grilling, roasting, and steaming.

Choose low-fat or nonfat dairy products.

Limit fast food and other low-nutrient snacks, such as chips and candy.

Limit sugary drinks, such as soda and fruit-flavored drinks. Serve water and low-fat milk instead.
