Good news about tomatoes

Apparently there's no salmonella threat. We can eat tomatoes again.

Although the FDA still believes that fresh tomatoes may have been a source of the bacteria in the early days of the outbreak, last week it said it is now safe to eat them because the trail had now turned toward fresh peppers.

Dr. David Acheson, the beleaguered FDA associate commissioner in charge of the probe, on Monday called the discovery of a genetic match for the salmonella strain on the jalapeño "a very important break in the case," although the ultimate source of the contamination has yet to be found.

Acheson was clear that, although the pepper came from a farm in Mexico, it has yet to be determined whether the source of contamination was on the farm, at the distributor or somewhere in between.San Francisco Chronicle

But there's more good news about tomatoes. New research shows the mechanism behind tomatoes' protective effect against prostate cancer. Rats fed tomato paste plus FruHis, a carbohydrate derivative present in dehydrated tomato products, lived longer than those in any other group. On postmortem examination, prostate tumors were found in 18% of rats in the tomato paste plus FruHis group compared with 39% of rats in the tomato paste only group, 43% of rats in the tomato powder group, and 63% of rats in the control group.

A combination of lycopene, an antioxidant in tomatoes that also protects against DNA damage, and FruHis caused a greater than 98% inhibition of prostate cancer cell growth in vitro compared with single agents.
