This article (and the original, which can be accessed here:

was so apropos of prior debates on this very board, that I thought I'd cross-post it here. This is why I am so skeptical of recent "scientist-recommended" diet trends like the sugar-is-toxic movement and the Paleo "lifestyle." It's a short read but quite informative. Full disclosure (in case you didn't know) is that I'm a research scientist and a physician.

BTW, before someone jumps on me to say that Paleo, (or sugar-free, or wheat-free, or vegetarian, or whatever restriction they follow) works for them when nothing else ever did, please note that I am NOT stating that eliminating your trigger foods won't help you keep weight off. Of COURSE that works. And if your trigger foods are wheat, or sugar or fat-laden, then it's only common sense that staying away from them will promote your weight maintenance efforts. I'm just saying that there's a difference between foods that are triggering and foods that are somehow "toxic" in moderation to an omnivore.
