Patients with atrophic gastritis need to eat more pasta as well as low-fiber foods to supplement their nutrition as needed. 1. Eat more pasta: pasta is easier to digest, is a kind of alkaline food, will not cause heartburn symptoms, can be eaten in moderation, not excessive consumption, to avoid increasing the burden on the stomach and intestines. 2. Low-fiber foods: foods too rich in fiber are likely to encourage faster gastric peristalsis, which can easily aggravate the burden on the stomach, so it is recommended that patients eat more low-fiber foods, such as winter squash, cucumbers, potatoes, and tomatoes. 3. Supplemental nutrition according to the needs: if the stomach acid is not much, you can drink some thick soup or gravy to stimulate the secretion of stomach acid and promote appetite; if the stomach acid is too much, you need to avoid acidic food or concentrated broth; if anemia, you can eat more eggs and animal liver to replenish blood. In addition, the treatment of atrophic gastritis is a relatively long process, patients need to actively accept the treatment, and actively regulate the diet.
