This book does not pretend to cover all products. There are too many items on food store shelves to try to be "complete." Rather, the idea is to provide representative product samples to increase awareness and give consumers a better idea of what they are buying and its benefits. There is no such thing as "best buy." Some shoppers look for quality. Others are motivated by nutrition. Price can be a very strong consideration, but not for everyone. The basic philosophy of this book is not to push consumers into any specific direction. Rather, the intent is to make consumers aware of what they are buying, so they can choose a healthier diet.
