Another health tenet stricken: Fruits and veggies don t decrease cancer incidence.

Consumers looking to take dietary steps towards cancer prevention might want to hold off on a daily V8 regimen. The British Journal of Cancer reports that increasing fruit and veggie consumption has little impact on cancer prevention, at least among well-nourished populations. Dr. T.J. Key, author of the review article, concludes that dietary advice pertaining to cancer prevention should put most emphasis on the well-established adverse effects of obesity and high alcohol intakes.

There goes another standard public health belief, laments ACSH s Dr. Elizabeth Whelan. That eating more fruits and veggies can prevent cancer has been a tenet for 15 years. A great pillar has fallen.

Adds ACSH's Dr. Gilbert Ross, The author did not include the most obvious way to reduce cancer risk by not smoking because his focus was purely on dietary factors.
