Care to elaborate? Assuming the Walmart has their standard grocery section they will sell fresh fruits/vegetables, meat, dairy, eggs, grains and the like. It may not be the highest quality but it won't kill you.

Agreed. The assortments available at all of my local Walmarts are on par with the local big box grocery stores. This includes produce, bakery, deli, and prepared items.
