This may be a difficult question to answer for most of us; because we may not know how much is enough! Before we refer to a specific amount, it may be necessary just to say that “we all need to eat variety and plenty of vegetables and fruits every day”.
Vegetables and fruits have plenty of essential nutrients for health. There is a lot of evidence that eating plenty of vegetables and fruits contribute a lot into prevention of many diseases including many types of cancer. Vegetables and fruits have natural compounds like beta carotene and vitamin c that helps to reduce the risk of many types to cancer. They also have other important nutrients like folate, dietary fibre, vitamin E and other minerals which are all very important in reducing many types of cancer.
