Bunnabear, I'm not sure what your meal plan looked like before, but you can probably make the same foods at home pretty simply. If you are manipulating the ingredients, it's definitely different than when it's processed via a factory.
I actually never ate a lot of premade food aside from bread but do buy crackers, jelly, cereal, oatmeal for my daughter. It's shocking to see some of the random ingredients in these. I'm not entirely comfortable making these items myself all the time, so it's been fun to look around and find the best option at the stores.
I noticed when I cut the "crap," my symptoms (docs were thinking Lupus testing was next. I originally got a false positive for Lyme and additional diagnoses for all of the symptoms) disappeared. The main problems were swelling/pain/exhaustion.
This is the best thing I've ever done for myself, and hope you soon feel the same!
