All of you, but particularly middle-aged and elderly men, should think very seriously about removing tomatoes from your diet. Tomatoes are the richest natural source of lycopene, a flavinoid demonstrated to have powerful anti-cancer and anti-oxidant properties. Lycopene is believed to be particularly effective in reducing the risk of prostate cancer.

OK, it's sponsored by HJ Heinz, but it seems a lot more balanced than most web sites put out by drug and supplement manufacturers.
The effect was originally discovered by researchers who found a very low incidence of prostate cancer in the Mediterranean countries.
Personally, I've had many friends die of prostate cancer, who may have been senior citizens but were otherwise in great shape. Unfortunately because it occurs mostly in elderly men (amongst Caucasians at least - men of African extraction tend to contract it earlier, maybe because their ancestral diet was richer in flavinoids?), I don't think it's taken as seriously as other cancers by the medical profession. I would think very carefully about cutting out tomatoes, unless you are able to replace the lycopene from another dietary source or take lycopene supplements.
PS
There are apparently a number of health benefits for women as well.
