> Plant-based foods (i.e. derived from fruits and vegetables) are particularly rich in cancer-beating molecules . . . Evidence from experimental studies has implicated multiple mechanisms of action by which dietary agents contribute to the prevention or treatment of various cancers

I prefer to say that a lack of fruits and vegetables causes cancer rather than they prevent cancer. Logically equivalent, but it leads me to consider them normal and packaged food abnormal.

Anyone can define normal for him or herself, but this way motivates me to eat more of them, as does discovering through experience how much more delicious they can be.
