>That said the study is highly biased. The "native" people are always laughing in the photos and the "modernized" people are looking sad.

But this doesn't explain away the order-of-magnitude differences in dental health Price found everywhere he went between people living on traditional diets (who typically didn't have toothbrushes, either) and those living on processed diets.

Oh I'm sure that eating those things is bad for your teeth if you don't brush them, simply because the bacteria grow on that kind of stuff (actually I already said this). I'm just saying that the studies sound unscientific; he sounds like he's trying to prove a point.

The traditional diets (which varied dramatically, by the way) resulted in consistently good teeth for people who never touched a toothbrush. In fact, their results were much better than those of people on processed diets who had toothbrushes. That's the point.

Right. My point is that a scientific text has the form "we researched this and here are our findings: things that support theory X and things that support (not X)" rather than "this is my point X and here is evidence for X".

Have his findings been independently verified? Especially his claims that the bone structure is better in the individuals on native food, for which he provides almost no evidence.
