Fruit causes cancer.
It is not true. In fact, researches show that there is a link between eating fruits and reduced chances of cancer. The theory is that since cancer cells feed on sugar, cancer patients should avoid fruit to make sure those cells don't grow out of control. Obviously, they don't realize that blood glucose can be created by any food you eat. Even if you avoid sweet fruit but eat more protein or fat, those nutrients will be converted to glucose and fed to the cells.
