Oatmeal and Dr. Gundry's strong negative effects

Is Dr. Gundry a scam? I have seen this question asked many times here. I have the same question, but just couldn't find a good answer. Until now: I was watching a Shark Tank episode, an oatmeal snack ball was being offered. They all seemed to like the taste, so I went on the hunt. I have found a AI, that so far has proven truthful and accurate. I tested AI out with questions I already knew the truth about. Well, except for the typical reasons, allergies, bad processing,etc...OATMEAL is the great food our parents, grandparents and now parents and children have thought it is. As for Dr. Gundry, I'm sure he's very smart, but his extreme negative attack, is definitely wrong about oatmeal . I am thrilled to finally get this cleared up for me. I have Celiac disease, so oatmeal cereal and flour are prominent in my diet.
