THE WHITE TEETH DIET
Fruits and vegetables that must be chewed act like a toothbrush while you eat, scrubbing the surface of your teeth, removing food particles and preventing plaque build-up. These foods also massage the gums, which stimulates blood flow and helps keep gums healthy. Best foods to eat: Apples, carrots, cauliflower, green beans, broccoli, pineapple, celery and hard cheeses.
When the flow of saliva is increased, it helps keep teeth whiter by essentially rinsing your teeth as you eat. Best foods to eat: Citrus fruits, such as grapefruits, limes, lemons and oranges, as well as strawberries.
What you don't eat is almost as important as what you do eat when it comes to maintaining white teeth. Zybutz offers this rule of thumb: If a food will stain your shirt, then it will also stain your teeth. Foods to avoid: Red wine, tea, coffee, cola and sports drinks, blackberries, blueberries, pomegranates, curry sauces, soy sauce and anything that is artificially colored.
