Bananas, grapes, strawberries, melons, and oranges are all fruits we are familiar with. Fruits are naturally sweet and taste great. Not only are they tasty, they are part of a balanced diet. One thing you need to be aware of with fruit is their acidity. They can cause the enamel on your teeth to dissolve which could lead to cavities and other dental health problems. Too much acidity can cause heart burn. Fruits are bright in color and bold in taste. They are a big part of the food pyramid. You should have one to two servings of fruit each day.
