Fructose consumed with glucose in small amounts from raw honey seem to be fine. However, excessive fructose consumption appears to be extremely negative.
A very recent study "Fructose stimulated de novo lipogenesis is promoted by inflammation" shows that fructose causes inflammation and liver cancer. In the experiment mice either received 70% of the calories from fructose or 70% from corn starch. Both groups otherwise received 10% fat and 20% protein. As far as I know corn starch does not contain any significant amount of nutrients and is nearly all carbs. Hence, Peat's argument that excess calories cause NAFLD is not accurate. Also Peat is very much against starch but the control group did much better than the fructose group. Basically the study found fructose causes:
Lastly, fructose inhibits calcium absorption. So it reduces the supposed benefits from the high calcium intake on a Peat inspired diet.
As far as I can tell these studies are well designed or am I missing something? Is there any good evolutionary evidence for high fruit consumption by humans or our predecessors within the last 3-4 million years ?
