Sic transit ...

I'm wowed by the 3 stunning turnabouts coming out of the Women's Health Initative. First, there's fat, previously bad for your heart, now not a problem. Then there's that hot-flash-reducer cum great-skin hormone therapy beloved of menopausal women, now a problem and causing an increased risk of heart ailments as well as breast cancer. Finally (for the moment at least) there's that old bone strengthening standby, Vitamin D and calcium, now considered unhelpful and raising the risk of kidney stones.

In the same vein, it seems that glucosamine and chondroitin sulphate don't alleviate arthritic pain (but may in some cases).

I wish there were a moral here, but I can't come up with one.
