Wheat remains one of the primary staple grains in the United States, and the glycemic load of processed wheat is a likely contributor to America's obesity epidemic. Rice contains considerably less fat, making it a superior source of carbohydrates. Rice-based diets have been used historically to address a number of medical conditions, and have gained some popularity as a means to help lose weight.
The health benefits of unpolished, brown rice outweigh those of white rice, as its whole grain provides more fiber, iron, B vitamins and other nutrients. (There are 1.5 grams of fiber per half cup of brown rice-almost three times the fiber in the same amount of white rice.)
