I just bought Quaker Yan cereal. Some people say that cereals are inedible. What happened?

Personally, I think oatmeal is good for breakfast, and coarse grains are good for my health. But some time ago, I said it was best not to eat oats, because oats contain gluten. This thing is harmful to human body, and long-term consumption will increase the risk of esophageal cancer. In recent years, gluten-free foods have become popular in Europe and America. You can check the specific hazards of gluten yourself.
