Interesting. Have people started offering cookbooks, recipe guides, and so forth, predicated on these principles? No gluten, wheat, and dairy would knock out quite a bit of my diet.
The diet ends up being pretty close to paleo. Other things that are commonly cut are soy and eggs. And no meat that is grain fed, so that mainly leaves grass fed beef, game, lamb, etc.
It can be a real pain in the f'in ass but once on the diet I've felt and looked the best I have in years.
(I forgot to mention, in addition to being diagnosed with the 677T mutation I also found out that I had severe IgG food sensitivities to gluten, oats, dairy, soy, all eggs, all fowl meat, almonds, peanuts, cranberries... shudder to think the 10 years I spent being vegan eating tofu and seitan full-time...)
