It is very common in my practice to encounter what I have been calling “gluten sensitivity”. Both for myself and many of my clients I consistently find that restricting consumption of wheat quickly drops 10 lbs of water weight, reduces inflammation in the gut, improves the skin, cognition, digestion, and vitality, and has a wide range of effects. It has puzzled me that sticking with native grains and consuming other grains containing gluten seems to be OK1. These papers discuss why:
GLUTEN SENSITIVITY MAY BE A MISNOMER FOR DISTINCT ILLNESSES TO VARIOUS WHEAT PROTEINS
THE WAR ON GLUTEN (Science 0618)
It appears that although my recommendation to restrict wheat intake has been accurate, the reasoning behind it (increased gluten levels from breeding) has not.
