Over the past few years I've been working on trying to lower the amount of processed, "industrial" food in my diet. I don't agree with all of Michel Pollan's arguments in his recent New York Times Magazine article (Unhappy meals), but I do think he's right that we'd be a much healthier society if processed foods didn't supply the majority of our calories. We might be getting all of the named nutrients through industrial fortification of nutrient-poor refined foods, but it makes sense to wonder if it wouldn't be better to be eating the unprocessed food that has all the nutrients (both named an unnamed) already built in.
Last week I got a grain mill, bought several sacks of organically grown whole grains (hard red spring wheat, rye, and oat groats; yellow corn on the way) and have been working them into my diet. Steel cut oats with a little rye and wheat cooked into porridge for breakfast, and whole flours baked into bread for lunch.
Why mill my own? Turns out that the oils in most whole grains spoil rapidly after milling (which is one reason why refined grains have become so popular with producers and retailers, and why refined food has to be fortified with nutrients lost during processing), so the whole flours, corn meal, and other grains you buy in the supermarket have probably already started getting rancid. Corn is especially prone to this because, according to The Laurel's Kitchen Bread Book, corn has been selectively bread to maximize oil production in the seed, which contributes to a much shorter shelf life when the whole grain is milled. Whole grains will last years if they don't get wet or infested with bugs. I can also get organically grown whole grains, and that's not always a choice at the supermarket.
I got a Family Grain Mill, which is an inexpensive, but efficient mill. It's mostly plastic, which means it probably won't last forever, but it does a nice job at milling grains to any size from practically whole all the way down to flour. Milling grain into flour takes two passes, one from whole grain to grits size (which raised the temperature of my grain from 59°F to 73°F) and a second pass to flour (raising the final flour to 84°F, which is perfect for forming a warm dough that the yeast can groove on).
Yesterday I baked my first 100% whole wheat bread using grain I milled into flour that same day. I didn't have any trouble getting a nice elastic dough, and the bread turned out nicely.
