In this video, Dr. Berg talks about the big problem with gluten-free. Gluten is the protein part of wheat or grains that causes celiac(an inflammatory condition of the gut). Most people are sensitive to gluten that causes inflammatory problems not only with the gut but also in the thyroid and many different parts of the body.
It is very essential not to consume gluten. When you remove the gluten you’re increasing the concentration of carbs in that grain and that will spike the blood sugars more and causes more insulin which is also going to cause more inflammation.
