Dietary Management of Gastritis

Primary Dietary Irritants to Eliminate

The American Gastroenterological Association recommends that alcohol must be limited or eliminated entirely as it is a well-established gastric irritant that directly damages the gastric mucosa 1
The American College of Gastroenterology suggests that coffee and tea should be restricted to a maximum of 3 cups per day, as caffeine stimulates acid production and can worsen symptoms 3, 4
Patients with gastritis should avoid all carbonated beverages, including fizzy drinks and sodas, as they increase gastric distension and reflux 1, 2, 3
The Clinical Gastroenterology and Hepatology society recommends that spicy foods should be eliminated as they are consistently identified as gastric irritants across multiple guidelines 5, 1
Fatty and fried foods must be avoided as they slow gastric emptying and worsen symptoms 5, 1, 2
Chocolate should be eliminated as it reduces lower esophageal sphincter pressure and promotes reflux 1, 2
Citrus fruits and acidic foods, including tomato products, should be limited or avoided as they may precipitate heartburn and worsen gastric irritation 5, 1, 2

Raw vegetables, particularly cruciferous vegetables, should be avoided during acute symptoms as they increase gas and bloating 5, 6
Fresh fruit should be limited to 3 portions per day to avoid excessive fructose intake 3, 4
Citrus pith and persimmons should be avoided as these can form phytobezoars in the stomach 7, 2
Red meat should be limited and replaced with lean proteins like chicken, turkey, or fish 5, 1, 2

Patients with gastritis should eat 4-6 smaller, more frequent meals throughout the day rather than 3 large meals to reduce gastric distension 1, 6
Eating should be avoided within 2-3 hours before bedtime to prevent nighttime reflux 2
Regular meals should be maintained, and missing meals or leaving long gaps between eating should be avoided 3, 4
Small bites should be taken, and food should be chewed thoroughly in a relaxed manner 7, 2, 6
Liquids should be separated from solids during meals to reduce gastric distension 1, 2, 6

Cooked vegetables are better tolerated than raw vegetables 5
Lean proteins, such as poultry and fish, should form the basis of protein intake 5, 1
Whole grains can be consumed in moderation, excluding high-fiber varieties during acute symptoms 1
Legumes can be consumed at least twice weekly once symptoms are controlled 1
At least 8 cups of fluid per day should be consumed, preferably water or non-caffeinated herbal teas 3, 4
