They've finally published a research study that seems to indicate BPA is bad for humans, "that among 1,455 U.S. adults, those with the highest levels of BPA were more likely to have heart disease, diabetes and liver-enzyme abnormalities than those with the lowest."
BPA is hard to avoid. It's not only used for plastic utensils and beverage containers, but it's used as a lining in canned foods, where it can apparently leach out.
So... the people with the highest levels of BPA are likely to be those drinking lots of bottled beverages and eating lots of canned food? Gee.
I can't see any easy way of removing the effects of that type of diet from the study (find people drinking lots of sugared drinks from non-plastic, non-can containers???). But maybe the researchers could, and there are some animal studies that were much more controlled, so I'm not saying the BPA doesn't affect health, just wondering how accurately they can gauge the effect.
Also, bariatric surgery to combat obesity may become passe. They've discovered that injecting a chemical into the blood vessels connected to the top of the stomach will reduce the "hunger" hormone as much as the surgery. They've only tried this in pigs so far (stop that, I mean real pigs, please!) but the chemical is already approved for treating varicose veins. This doesn't have the physical effect of reducing stomach size, so it may not work as well in humans since we have so many more things affecting appetite than just hormones, but it's heading towards an alternative treatment that's much, much safer.
