The current recommendation is to eat 5 or more servings 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. As per Ayurveda, one should mix all seven colours and six tastes when choosing fruits and vegetables.
As per the USDA Food Guide Pyramid, one should take 5 to 9 servings of fruits and vegetables every day. Fruits, vegetables and grain products that contain fiber, particularly soluble fiber, may help reduce the risk of coronary heart disease. Fiber-containing grain products, fruits and vegetables also reduce the risk of some cancers, said Padma Shri and Dr B C Roy national Awardee Dr KK Aggarwal President Heart Care Foundation of India and MTNL Perfect Health Mela.
