Intolerance to wheat is far more common than doctors typically recognize. I was once fooled enough so that when I was in medical school nearly 25 years ago my nickname was "Dr. Fiber," as I was always preaching the benefits of whole grains.
Little did I know that wheat, and nearly all other grains, rapidly convert to sugar and rapidly accelerate aging and chronic illness in most, although certainly not all of us.
Unless you are seriously underweight, most of us would best be served by limiting or avoiding wheat altogether. I was well over 40 years old before I realized this kernel of truth and I probably chopped a good 20 years off the end of the limit of my life span by not applying it earlier.
