It seems we could divide the food world into two groups. Commodity foods and Real Foods.
The commodity includes all foods that can be stored, and shipped great distances. These are processed and grains.
Real food likely do not keep very long without care and need to be preprepared, without converting them into hyper-palatable foods. Hyper-palatable are foods that you want more of. (A prep end, just for you english majors).
Which group is your diet in, Laura?
