According to a 2022 cross-sectional study, people with chronic gastritis symptoms often have irregular eating times and are more likely to eat trigger foods. Navigating your diet is crucial when a flare-up occurs, but knowing what should you eat when gastritis flares up can help manage symptoms and support healing of the stomach lining.

Quick Summary

This guide provides a detailed overview of foods to incorporate and avoid when experiencing a gastritis flare-up. It focuses on gentle, anti-inflammatory options that aid in symptom relief and promotes strategies for healthier eating habits to support stomach healing.

Key Points

Consume Bland Foods: Opt for gentle, low-acid options like bananas, applesauce, oatmeal, and plain rice during a flare-up.
Choose Lean Proteins: Select easily digestible protein sources such as skinless chicken, fish, and eggs, prepared with minimal fat.
Embrace Anti-inflammatory Foods: Incorporate foods with anti-inflammatory properties like ginger, turmeric, and berries to help calm irritation.
Avoid Trigger Foods: Steer clear of high-acid, spicy, high-fat, fried, and processed foods that can exacerbate symptoms.
Adopt Mindful Eating Habits: Eat smaller, more frequent meals, chew thoroughly, and stay hydrated to reduce the workload on your stomach.
Use Gentle Cooking Methods: Prioritize baking, boiling, and steaming over frying to reduce added fat and ease digestion.

Understanding Gastritis and the Role of Diet

Gastritis is an inflammatory condition of the stomach lining that can cause uncomfortable symptoms such as indigestion, bloating, nausea, and abdominal pain. A flare-up can be triggered by various factors, including bacterial infections like H. pylori, certain medications, stress, and poor dietary choices. While medical treatment is essential, a targeted dietary approach can significantly help manage symptoms and promote recovery by reducing irritation to the stomach lining. The goal is to consume foods that are easy to digest, low in acid, and have anti-inflammatory properties while avoiding common irritants.

Soothing Foods to Eat During a Gastritis Flare-Up

Focus on bland, gentle foods during a flare-up to give your stomach a rest. These foods are less likely to increase stomach acid production and can help soothe the inflamed lining.

Bland, Low-Acid Foods

Oatmeal: Plain, unsweetened oatmeal is high in fiber and can have a soothing effect on the stomach.
Bananas: These are low-acidic and can help produce protective mucus in the stomach.
Melons: Fruits like cantaloupe and honeydew are generally non-acidic and well-tolerated.
Plain Rice: Brown or white rice, well-cooked, is easy to digest.
Applesauce: Unsweetened applesauce can be a gentle and easily digestible option.
Boiled Potatoes: A plain baked or boiled potato is gentle on the stomach.

Lean Proteins

Lean proteins are easier to digest than high-fat meats and provide essential nutrients for healing.

Skinless Poultry: Baked, grilled, or poached chicken and turkey are excellent choices.
Fish: Steamed or baked fish like salmon and trout provide anti-inflammatory omega-3 fatty acids.
Eggs: Scrambled or boiled eggs are a great protein source, but avoid cooking them in excessive butter or oil.
Tofu: A good plant-based protein option, especially when prepared mildly.

Healthy Fats and Probiotics

In moderation, healthy fats can reduce inflammation, while probiotics support gut health.

Olive Oil: A small amount of olive oil is a good source of healthy fat.
Avocado: Provides healthy fats and is generally well-tolerated.
Plain Yogurt or Kefir: These contain beneficial live cultures that may help balance gut microbiota, especially when an H. pylori infection is a factor.

Anti-inflammatory and Herbal Remedies

Ginger: Known for its anti-inflammatory properties, ginger can be consumed as a tea.
Turmeric: Another anti-inflammatory spice that can be added to mild dishes.
Herbal Teas: Chamomile, ginger, and fennel teas can help soothe the stomach.

Foods to Avoid During a Flare-Up

Certain foods can exacerbate gastritis symptoms by irritating the stomach lining and increasing acid production.

High-Acidic Foods

Citrus Fruits and Juices: Oranges, lemons, grapefruit, and tomatoes are highly acidic and should be avoided.
Spicy Foods: Chili peppers, hot sauces, and heavy spices can irritate the stomach.

High-Fat and Fried Foods

Fried Foods: French fries, fried chicken, and other greasy items are hard to digest.
Fatty Meats: Red meat, sausage, and bacon can prolong digestion and increase irritation.
High-Fat Dairy: Whole milk, cream, and full-fat cheese can worsen symptoms.

Irritating Beverages

Coffee and Caffeinated Tea: Caffeine stimulates stomach acid production.
Alcohol: Can directly irritate and erode the stomach lining.
Carbonated Drinks: Sodas and sparkling water can cause bloating and discomfort.

Comparison of Cooking Methods for Gastritis

Using gentle cooking methods is key to preparing meals during a flare-up. The way you prepare food is just as important as the food itself.


Recommended Methods	Methods to Avoid	Reasoning
Baking	Frying, deep-frying	Frying adds excess fat, which slows digestion and increases irritation.
Boiling	Pan-frying, air-frying	Boiling makes food soft and easy to digest, reducing the strain on the stomach.
Steaming	Grilling (over high heat)	Steaming retains nutrients and keeps foods gentle and moist, unlike high-heat grilling which can be harsher.
Poaching	Roasting (with high oil/seasoning)	Poaching, especially with gentle herbs, keeps food low-fat and easy on the stomach.

Practical Tips for Managing Flare-Ups

Beyond choosing the right foods, adopting smart eating habits can make a significant difference.

Mindful Eating Habits

Eat Smaller, Frequent Meals: Instead of three large meals, eat five or six smaller, more frequent meals. This prevents overloading the stomach and helps regulate stomach acid.
Chew Food Thoroughly: Chewing food well aids digestion and reduces the burden on your stomach.
Don't Lie Down After Eating: Remain upright for at least 2-3 hours after a meal to prevent acid reflux.
Stay Hydrated: Drink plenty of water throughout the day to support digestive function. Sip on water between meals rather than chugging it with food, which can dilute stomach acid.

Lifestyle Adjustments

Manage Stress: Stress can worsen gastritis symptoms by increasing stomach acid production. Incorporate relaxation techniques like meditation or deep breathing.
Avoid Smoking: Smoking constricts blood vessels in the digestive system and reduces blood flow to the stomach lining, hindering healing.

Conclusion

Successfully navigating a gastritis flare-up requires a proactive approach to diet and lifestyle. By focusing on bland, low-acid, anti-inflammatory foods and avoiding common triggers like spicy, fried, and acidic items, you can effectively soothe your stomach and support its healing process. Eating smaller, more frequent meals and managing stress are also crucial components of a successful recovery plan. While dietary changes can provide significant relief, it is essential to consult with a healthcare provider or a registered dietitian for a personalized treatment plan, especially if symptoms persist.

Expert Perspective

According to Rita Faycurry, RD, acute gastritis symptoms may improve within a few days to weeks of dietary changes, while chronic gastritis can take months. Many notice relief from eliminating triggers like spicy foods, alcohol, and caffeine within the first week.
