"Going Against The Grain" is an interesting book. The thesis is that grains are causing many of the diseases of civilization and that humans - especially children should be eating far fewer than our current practice. Certainly avoiding grains should keep our carbohydrate consumption down which should reduce our Type 2 Diabetes epidemic. Ms. Smith makes a good case for avoiding grains altogether. But anyone who has any sort of digestive difficulties should definitely try an avoidance diet.Furthermore, the author give the reader the names of the tests we should ask our doctors for. If one is having trouble with any part of the digestive system, this might help.Although the book has few recipes, the ones it has sound great, and I can't wait to try them.
