Patients with gastric celiac disease are not recommended to consume cakes because they are a high-fat, high-cholesterol, high-sugar classified food, which, when consumed by patients, will not only increase the functional burden of gastrointestinal tract tissues and easily cause indigestion, but will even induce or aggravate adverse symptomatic reactions such as gastric distension, nausea, vomiting, acid reflux and heartburn in patients. For patients with gastric ulcer, during the daily dietary care, more foods high in vitamins, minerals and amino acids should be chosen, such as pumpkin, yogurt and yam. Vitamins and minerals can not only supplement essential nutrients, but also play a role in enhancing the ability of the human immune system; amino acids, as the main synthetic substance of human collagen, have the effect of promoting the regeneration and healing of damaged tissues in the stomach and speeding up the recovery of the patient’s condition, etc. Avoid spicy, cold, greasy and other stimulating substances, such as doughnuts, chili, animal offal, etc.
