The answer is a definite yes. Good nutrition contributes greatly to healthy teeth, gums, nervous system, and bones. By contrast, poor nutrition leads to poor dental health, lack of energy, poor self-esteem, and that relationship killer, bad breath. Your gums need proper nutrition to remain healthy and be less prone to gum disease. Poor nutrition can lead to decreased saliva flow, and that can cause extensive cavities and bad breath. Loading the mouth with a constant supply of sugars and starches allows the bacteria in the mouth to grow quickly and increase the risk of decay and gum disease. Soda is also very damaging. Not only does the sugar in soda help cause decay, but also the acids in the soda can dissolve your tooth enamel.
So what's the solution? Eat nutritious foods, and eat mostly at mealtimes, brushing immediately afterwards. If you must snack, choose raw, low-sugar fruits, raw veggies, nuts, cheese, plain yogurts, boiled eggs, herbal teas and flavored waters. Drink up to 10 glasses of clean water per day. With consistency, evidence shows that you'll not only maintain your teeth, but you'll revitalize your entire metabolism, improving body weight, physical endurance, mental alertness, and well-being.
