Half of my wife's family live in Southern Ireland and drink raw milk as their guts are adjusted to accept this - I wish I were in this position. We get our milk, cream and butter delivered by a local farmer directly (how lucky are we), and most meat and fish from a farmers market in Manningtree. An interesting point is that this farm do not use the homogenisation process which the farmer spent some time detailing how this changing of the fat molecules could contribute to cancers (interesting that Vegans have said similar). My hypothesis is that "we" should try to limit food noise as much as possible, so by noise I mean bad quality foods (often this is the modern sweet stuff, specifically designed with sugar, man made fats and salt for hyperpaletability), I believe that exercise, sleep and fasting help with what I would call clearance and mitigation of some of the potential poison we ingest.
