There is no such thing as what kind of food celiac disease is most afraid of, but celiac disease should eat less food that contains acid, irritating food, and hard, indigestible food. Celiac disease is caused by the exposure of deep-seated nerves in the stomach wall, so acidic and alkaline stimuli can cause stomach pain, stomach cramps and other symptoms, for example, lemon, lime, bamboo shoots and other acidic foods can cause stomach pain and other symptoms, is not conducive to the healing of celiac disease. Hard and indigestible food can aggravate gastric mucous membrane erosion due to mechanical stimulation of the stomach wall, and may also cause bleeding and other symptoms, so it is recommended that patients reduce or try not to eat this kind of food. To sum up, we suggest that patients combine their own symptoms and gastroenterology doctor’s advice to make a judgment, and we also suggest that they go to a specialist for examination and treatment of celiac disease.
