Something as simple as eating an apple a day may help to prevent cancer. Apples contain at least two kinds of cancer-inhibiting compounds, flavonoids and phenolic acids. Together these two compounds may protect against damage to cells that can trigger malignancies. They may also prevent emerging cancer cells from further dividing. What a tasty way to perhaps protect yourself from cancer. I think it is worth eating an apple a day!
Berries are another good choice for the same reasons as apples.
