Unfortunately, a lot of the products whole foods carry is pretty much as bad as conventional stores. A year or two ago, I bought a cupcake from their bakery thinking-assuming--it was homemade.

Yet, I find great stuff there all the time. Its the best place to get grass fed meats and my produce. We have the biggest whole foods on the east coast and I want to stay in the area simply because of whole foods
