Obviously you have to consider where the hell you're living. In the UK I eat oats all the time and they're dirt cheap. I knew a guy when I was in japan who ate oats every day. I thought he was absolutely insane. You could barely buy oats there. I ate brown rice mixed with barely to get nutrient rich grains because it was actually readily available and affordable. Let's not be stupid out here and act suprised when our ideal diet in one country is too expensive in a totally different climate - there are many plants in the world, use something else. Oats are only so revered in the west because they're a good thing that is AVAILABLE.
