THE WHITE TEETH DIET It's time to load up your plate with broccoli, carrots and cauliflower. If you pay attention to what you eat -- and what you don't eat -- you can clean and whiten your teeth naturally, says UK dentist, Dr. Anthony Zybutz. There are three components to the white teeth diet: chewing, saliva production and staining, Zybutz tells London's Daily Mail : 1. Chewing 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. 2. Saliva 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 strawberrie
