"Whole grain" is a generic term used to apply to any grain that hasn't been stripped of the bran or fiber found in its core. This fiber, along with some nutrients, is what makes whole grains good for you. Any grain - wheat, oats, etc - can be sold as a "whole grain" depending on how it is processed. The trick is to read the food labels and make sure that the ingredients list "whole" grains. Don't simply buy "wheat" bread, for example, the label must say "whole wheat".

I've never tried growing grains at home, and suspect it would be difficult. A good alternative for the home garden, which isn't a grain but which has lots of fiber, is collard greens.

We often prepare recipes using bulgur wheat or barley. Corn and cornmeal are also considered whole grains. I have read a lot about quinoa lately, but haven't tried it yet. You can find these at the Dekalb Farmers Market at reasonable prices. Other whole grains are available there as well. You can usually find whole grains in your local Kroger or Publix, but they can be expensive.

I added a link to a recipe using bulgur which we have prepared many times and always enjoy.
