A few thoughts on Minerals, Milling, Grains and Tubers

One of the things I've been noticing in my readings on grain processing and mineral bioavailability is that it's difficult to make whole grains into a good source of minerals. Whole grains naturally contain more minerals that milled grains where the bran and germ are removed, but most of the minerals are bound up in ways that prevent their absorption. The phytic acid content of whole grains is the main reason for their low mineral bioavailability....
