I know that different things work for different people, but if you really want to help your son, you should get the book "The PH Miracle". It is written by Dr. Young. It deals with blood PH as a cure for just about everything. I have had colitis for over 10 years now and started the diet prescibed in the book and I am cured. The bottom line is people with digestive diseases should become 80% vegetarians. This means that 80% of our diets should be vegetables and as raw as possible. People think that being vegetarian means just not eating meat. People with our disease should also stay away from dairy, flour, fruits(fructose), pasta, and potatoes. If you read the book, it will explain in detail why. I truly hope you will give this a try because it truly works.
