You're right, Liz... when I first started reading Dr. Davis... I was impressed but as time when on... there were numerous flaws in his messages about what the majority of functional medicine MDs use as dietary guidelines. While it's still true that many people need to avoid wheat as well as gluten, that's often just not enough and one needs to limit all grains and focus on reducing a high carb count... especially those who aren't active enough to burn off the excess carbs.
As is so often the case, it's not simply a 'one-size fits all' approach when it comes to a dietary plan that is tailored to one's unique makeup. Reliably testing the critical markers becomes essential so that we can manage our diet and remain healthy as the years add up.
