The Happy Guide position on grains and dairy is “anyone with illness should quit grains and dairy” (see page 48 of the book).
In fact, I would encourage everyone to quit these foods. The Happy Guide diet does allow rice which is considered safe, and quinoa/millet which are not actually grains but seeds.
Here’s more from Kelly Brogan about a new study…
“Both celiac disease and non-celiac gluten sensitivity can result in autoimmune conditions including diabetes, arthritis, thyroiditis, and neurological conditions such as multiple sclerosis and gluten ataxia. This study aimed to elucidate the mechanisms underlying the neurologic manifestations of potentially undiagnosed sensitivity.
I’ve previously discussed the literature supporting gluten-brain clinical significance and highly recommend that anyone suffering from psychiatric or neurologic symptoms consider a month-long (at least) elimination of these two categories of foods, gluten and dairy.”
Grains and dairy are not natural human foods at all. For two and a half million years, since “homo” genus began, we did not have them in our diets, so it’s no wonder they cause so many problems. Quit, quit, quit!
