Just be aware you will be (indirectly) emitting more CO2, and using more pesticides and fertilizer by buying from Farmers Markets. So you have to decide what's more important to you. (Small farms are less efficient, less efficient means uses more energy and other inputs.)
There is a middle ground between the "processed foods from these mega corporations" (which I agree you should not buy) and farmers markets though: Just buy regular produce from a grocery store, and cook normal food.
