It is currently recommended that one should eat 5 or more servings of variety of fruits and vegetables daily to prevent cancer and heart disease. Fruits and vegetables contain vitamins, minerals, phytochemicals, and antioxidants and are low in calories. Those with the most color – dark green, red, yellow and orange – have the most nutrients. Carrot, Celery, Cantaloupe, Cucumber and Corn are the five "Cs" which can be incorporated in the five a day diet. One should mix all seven colors and six tastes when choosing fruits and vegetables.
The USDA new Food Plate recommends filling half your plate with fruits and vegetables.

Tips for safe eating
*Snack with raw vegetables instead of potato chips.
*Add fruits in breakfast.
*Prefer fresh fruit juice instead of a usual coffee, tea or soda.
*Wash fruits and vegetables with water and scrub with a dish brush when appropriate.
*Throw away the outer leaves of leafy vegetables, such as lettuce and cabbage.
*Peel and cook when appropriate, although some nutrients and fiber may be lost when produce is peeled.
*Avoid fruits and vegetables that look brownish, slimy or dried out. These are signs that the product has been held at an improper temperature.
