When I reached 45 years of age, I developed significant celiac. It’s genetic in my case. Haven’t touched wheat since. The idiotic Food Pyramid was pushed and forced for decades.
PS...we discovered the hard way that maltodextrin is dangerous. After it almost sent me to the hospital, I researched and found totally UNhelpful answers. One source even stated “maltodextrin may, or may not, contain wheat.” Gluten free diets and products have become a fad in some places. The most amusing one was “gluten free fresh strawberries.”
