Here is a short section from an article by Law and Wald in the British Medical Journal (BMJ) from 2002. They argue that the levels of both cholesterol (and blood pressure) in all westernised societies are far higher than those of our ancestors and the remaining hunter-gatherer populations dotted around the world.

Amyloid-beta is a by-product that is created when a normally occurring substance called amyloid precursor protein, or APP, a membrane protein that is found in neuronal synapses, is cleaved into three pieces. Normally, APP is split into two pieces, and everything is fine. But when APP is cut in thirds, one of the resulting fragments then becomes
