PART II: What Kind of Food Should I Eat?
RULE #38 - Favour the kinds of oils and grains that have traditionally been stone-ground.
When grindstones were the only way to refine flour and oil, flour and oil were generally more nutritious. In the case of grain, more of the germ and fibre remains when it is ground on a stone;you can't get white flour from a stone. The nutritional benefits of whole grains are impressive: fibre; the full range of B vitamins; and healthy oils, all of which are sacrificed when the grain is refined on modern roller mills (as mentioned, highly refined flours are little different from sugar). And the newer oils that are extracted by modern chemical means tend to have less favourable fatty acid profiles and more additives than olive, sesame, palm fruit, and peanut oils that have been obtained the old-fashioned way.
