For instance, organic milk will be in the dairy section and organically grown lettuce and bananas will be in the produce section, so you may have to walk through the entire store to get an idea of how much food is organic or natural.
Organically grown fruits and vegetables will be identified as such, and many grocery stores now post the name of the local farm where they are grown. In the meat department you will find certified organic and free range chicken and other meats and, here also, the local producer may be identified.
If you can, you may want to visit local farms that grow these foods in order to get firsthand information the special care with which they are produced. Purchase some of the natural and organic products if you can, and see if you can discern any difference between them and the other products you may have been eating and using.
