[QUOTE="fergus, post: 85550, member: 6150"] Excellent stuff and I agree with you AliB. There is a lot of ducumented evidence from colonial times in Africa particularly where the incidence of 'western diseases' obesity, hypertension, diabetes and many cancers were extremely rare when first studied. Within 20 years of the introduction of refined sugars and starches however, these disease rates appeared to rise exponentially. I agree that the diet we seem best adapted to in general terms is probably based around meat, fish and supplemented by seasonal vegetables and very occasional fruit. Again, in people suffering from these western diseases, many people seem to report that they go into remission when their diets revert to this type. What I don't see any evidence for is the idea that our ancestors ate a diet low in fat. I think this is an adaption of the ancestral diet idea to sit more comfortably with the very recent low-fat-is-healthy idea. Archaelogical evidence seems to suggest that where animals were eaten, [i]all[/i] of the carcass was eaten. No 'trimming the fat'. Brains were probably commonly eaten, the fattiest part of the animal, and it seems to me laughable that hunter gatherers would have avoided the most calorifically dense part of their kill. The counter argument is that wild animals were themselves less fatty. Again, however, human expansion around the world occurred as the ice ages retreated and we might assume that the animals at that time were most likely fairly well insulated themselves! What is beyond dispute is that the 2 greatest upheavals in our diet came 8-10,000 years ago when agriculture began and ~250 years ago during the industrial revolution. All the best, fergus [/QUOTE]
