Although I grew up on a farm in the middle of Kansas, we took the wheat and other grain to the elevator, and then went to the grocery store to buy all our food. Maybe it's a generational thing, but we should be growing our own food as much as possible! My wife was diagnosed with Graves disease, which is an auto-immune disease affecting the thyroid, and while it wasn't debilitating (we are grateful for that) we have to wonder if it had to do with processed food and our mass-produced food supply. Auto-immune epidemic anyone? Also, maybe a generational thing... we live in the city in Kansas City, but our kids want to move to the farm!
