As with all health decisions it is best to seek a medical professional's advice before making changes to your life and diet.  It is often difficult to find a health care professionsal that keeps up with all of the current research and is knowledgable in your personal health, so be prepared to bring along with you the references used on this site to have a discussion with your health care provider.  It is our experience that you must be your own health advocate and that might mean asking your doctor to go do some homework =).
