Research suggests that eating lots of fruits and vegetables may provide some protectionagainst several types of cancer. Studies have revealed that the risk of getting cancerassociated with the lowest intake of fruits and vegetables is twice as high as thatassociated with the highest intakes. This association holds for several types of cancer, including cancers of the breast, colon, pancreas, and bladder. A= Eating lots of fruits and vegetablesE= Getting cancer. If the general population did more of A, there would be less of E. If the general popluation does less of A, there will be more of E. method of concomitant variation

True

Explanation:

International Journal of Cancer published a research which suggests that eating lots of fruits and vegetables may provide some protection against cancers of breast, pancreas, bladder and colon.  The study was published online July 6, 2018. The study observes an average 50% reduction in the risk of cancers with higher intake of fruits and vegetables.

It was also found that 5.5 servings of fruits and vegetables each day lowers the risk of cancer by 11% especially breast cancer. Women with lesser intake are more prone to cancer. Thus, it has inverse relation to the risk of Cancer.
