Answer to Question 1

Possible benefit has been attributed, in part, to nutrients and phytochemicals with antioxidant activity, as these substances may prevent or reduce the oxidative reactions in cells that cause DNA damage. In addition, phytochemicals may inhibit carcinogen production in the body, enhance immune responses that protect against cancer development, or promote enzyme reactions that inactivate carcinogens. The B vitamin folate functions in DNA synthesis and repair; thus, inadequate folate intakes may allow DNA damage to accumulate. Fruits and vegetables also contribute dietary fiber, which may help to protect against colon and rectal cancers by diluting potential carcinogens in fecal matter and accelerating their removal from the GI tract.

Answer to Question 2

True
