Gastritis Diet: A Healing Plan for an Inflamed Stomach

Short answer: A gastritis diet favours soft, low-fat, non-spicy meals: lean protein, oats, bananas, cooked vegetables and plain yogurt or kefir if tolerated. Alcohol, NSAID painkillers taken without advice, very spicy food, and large fatty meals commonly worsen symptoms. Diet supports recovery, but H. pylori needs diagnosis and medical treatment.

Gastritis — inflammation of the stomach lining — affects an estimated 50% of the global population at some point, most often driven by Helicobacter pylori infection, NSAID use, alcohol, or chronic stress (Sipponen & Maaroos, 2023, Scand J Gastroenterol). While medication (PPIs, antibiotics for H. pylori) is often necessary, diet is the most powerful daily lever for reducing symptoms and supporting mucosal repair.

This guide covers what to eat, what to avoid, an H. pylori-friendly food list, and a 7-day meal plan calibrated for a sensitive stomach.

⚠️ Medical Disclaimer: This article is for educational purposes only. If you have black or bloody stools, persistent vomiting, severe pain, or unintentional weight loss, seek immediate medical care. H. pylori requires confirmed diagnosis and antibiotic treatment — no diet alone eradicates it.

What Gastritis Actually Is

Gastritis can be:

• Acute — sudden onset, usually from NSAIDs, alcohol binge, or stress
• Chronic — long-standing inflammation, most often H. pylori or autoimmune
• Erosive — visible damage to the lining, higher ulcer risk
• Non-erosive — inflammation without ulceration

The dietary approach is similar across types: reduce mucosal irritation, support the gastric mucus barrier, and avoid foods that increase acid output or slow gastric emptying.

Best Foods for Gastritis

Food Group	Examples	Why
Cruciferous vegetables	Broccoli, broccoli sprouts, cauliflower	Sulforaphane suppresses H. pylori
Probiotic foods	Plain kefir, low-fat yogurt, miso	Lactobacillus supports lining recovery
Lean protein	Chicken breast, white fish, tofu	Easy to digest, doesn't prolong gastric emptying
Soluble fiber	Oats, bananas, peeled apples	Coats mucosa, smooths transit
Healthy fats (small amounts)	Olive oil, avocado	Anti-inflammatory; large doses delay emptying
Green tea	2–3 cups daily, not on empty stomach	Catechins inhibit H. pylori
Berries	Blueberries, raspberries	Polyphenols reduce gastric inflammation
Honey (raw)	1 tsp daily	Modest antibacterial effect against H. pylori

H. pylori-Specific Foods

Three foods have human-trial evidence for H. pylori suppression (adjunct to, not replacement for, antibiotics):

• Broccoli sprouts — 70 g daily for 8 weeks reduced H. pylori markers (Yanaka et al., 2009, Cancer Prev Res)
• Cranberry juice (unsweetened) — 250 mL twice daily improved eradication rates
• Black cumin (Nigella sativa) seed — 2 g daily reduced H. pylori density

Foods to Avoid with Gastritis

• Alcohol — directly damages gastric mucosa
• Coffee (including decaf) — stimulates acid secretion
• Spicy foods — chili, hot sauce, raw garlic, raw onion
• Acidic foods — citrus, tomatoes, vinegar, pickles (during flares)
• Carbonated drinks — distend the stomach, worsen reflux
• Fried and high-fat foods — slow gastric emptying
• Processed meats — nitrates and high salt damage mucosa
• Refined sugar — feeds dysbiosis
• NSAIDs (ibuprofen, naproxen, aspirin) — switch with your doctor's guidance

Supplements with Evidence

Discuss with your doctor before starting:

• Zinc-L-carnosine — Japanese gastritis standard; supports mucosal repair
• DGL (deglycyrrhizinated licorice) — 380–760 mg before meals
• Mastic gum — 350 mg 3× daily for 14 days reduces H. pylori
• Vitamin C (food sources first) — adjunct in H. pylori therapy
• Probiotics — Lactobacillus reuteri and Saccharomyces boulardii most studied

FAQ

How long until gastritis heals on this diet? Acute gastritis typically resolves in 1–2 weeks once triggers are removed. Chronic gastritis improvement is measured in months and depends on resolving the underlying cause (H. pylori, NSAIDs, autoimmune).

Can I drink coffee with gastritis? Coffee — even decaf — stimulates acid and is best avoided during active inflammation. Many people reintroduce small amounts (with food) once asymptomatic.

Is intermittent fasting safe with gastritis? No. Extended empty-stomach windows raise acid exposure to the inflamed lining. Eat small, frequent meals instead.

Does milk help gastritis? Short-term relief, long-term harm. Milk briefly buffers acid but stimulates rebound acid secretion. Plain yogurt and kefir are better dairy choices.
