A well balanced diet helps prevent heart disease, diabetes, and tooth decay. Just like the body, the teeth and gums require vitamins, protein, calcium, and phosphorous to be healthy. A healthy diet includes an abundance of unprocessed foods like whole grains, vegetables, and fruits. Protein should be lean and come from a variety of sources like fish, chicken, eggs, beans, cheese, and yogurt. Choices should be low in fat, sugar, and salt. It is also important to portions in moderation. Even healthy foods like apples, carrots, and milk contain natural sugars that can lead to acid production. Some good guidelines are to avoid processed food and sugars, limit snacking between meals, rinse with water after snacks, and if you eat sugary foods and drinks eat them with meals.
