What you can do is "shop the perimeter" at the store. Supermarkets in the US are usually laid out where the meat, dairy, and produce sections are along the edges of the store, and the middle aisles have the prepared foods (comes in boxes, cans, etc.) The prepared foods are the ones typically loaded down with sugar and are highly processed, so only go down an aisle when there's something you really need there, like maybe a spice.
