Food prices are climbing, and some might be looking to fast foods and packaged foods for their cheap bites. But low cost doesn't have to mean low quality. In fact, some of the most inexpensive things you can buy are the best things for you. At the grocery store, getting the most nutrition for the least amount of money means hanging out on the peripheries-near the fruits and veggies, the meat and dairy, and the bulk grains-while avoiding the expensive packaged interior. By doing so, not only will your kitchen be stocked with excellent foods, your wallet won't be empty.
