<i>But I think the main reason there won't be a major behavioral shift anytime soon is that carbs taste great (...) and they're addictive and legal. </i>

I agree with you on that one, but I hope we're wrong. I mean, cigarettes are addictive and legal, too, and where the heck are you allowed to smoke nowadays? My former coworkers say they used to sit around smoking while they worked - and this was a hospital lab!! There were flamable chemicals everywhere! Obviously, this would never happen today.

I tell ya, though, I think we're about to see quite a disaster if "they" don't get their act together: look at the huge swell of aging baby boomers who are in their 50s, and imagine the diabetes and heart disease we're going to be looking at. What are *those* statistics going to look like? What about when most of them get *worse*, not better, by eating low-fat/high carb? *Then* will "they" start to listen?
