Plant diets ward off cancer?

Rounding up a number of recent articles from the Journal of the American Medical Association, the BBC feels it can claim that plant diets ward off cancer.

An expert is duly found to urge us to eat more fruit and vegetables, but what of the research itself?

One paper is about a slender association between eating red and processed meat and contracting colorectal cancer. Fair enough, though I noted that the increased risk ratios were barely significant.

The second paper concerned the disposition of people with high blood sugar levels to contract cancer. How this is supposed to support the "five pieces of fruit" theory is quite beyond me, since most fruit is packed full of sugar.

The third paper interested me greatly when I looked at the abstract a week or two ago, for it established that there was no protection from breast cancer to be gained by eating lots of fruit and vegetables, despite popular mythology.

It is interesting to note that not one of these papers shows any beneficial effects of eating large quantities of fruit and vegetables, but why let that small fact get in the way of the BBC's clear duty to promote orthodoxy?

UPDATE 24/01/05

The Junkman has taken a closer look at the red meat/ cancer paper and is not impressed.

Funny. I entered the comment below this morning and now gone. So I repeat:

Coffee is good to: it apparently repels liver cancer:

And I remember reading some years ago that tobacco smoke killed the germs in the throat (probably assuming the tobacco didn't kill the owner of the throat).

We better make a list of what to consume and see if we can live by it.
