When you have gastritis, you can eat most foods that are low in acid, low in fat, and gentle on the stomach. That includes lean proteins like chicken and fish, non-citrus fruits like bananas and pears, most cooked vegetables, whole grains, and fermented foods like yogurt. The goal is to avoid triggering extra stomach acid production while giving your inflamed stomach lining time to heal.
Diet doesn’t cause most cases of gastritis, but what you eat during a flare-up makes a real difference in how you feel. The right foods won’t cure the underlying problem, but they can reduce pain, bloating, and nausea while your stomach recovers.
Fruits and Vegetables That Work
Non-citrus fruits are your best options. Bananas (pH 4.5 to 5.2) and pears (pH 3.5 to 4.6) are particularly helpful because they can reduce gastric juice production, which protects the stomach lining. Apples, berries, and watermelon (pH 5.2 to 5.6) are also generally well tolerated. Avocados, with a near-neutral pH of 6.3 to 6.6, are both gentle and nutrient-dense.
Skip citrus fruits like oranges, lemons, grapefruits, and pineapple. Their high acidity (often below pH 4.0, with lemon juice as low as 2.0) can irritate an already inflamed stomach lining. Tomatoes fall into this category too, despite being a vegetable in most people’s minds.
For vegetables, most cooked options are safe and sit comfortably in the pH 5.0 to 7.0 range. Carrots, potatoes, sweet potatoes, zucchini, broccoli, cauliflower, spinach, peas, green beans, and asparagus are all good choices. Cooking softens the fiber, making these easier to digest than raw versions. If you’re in the middle of a flare, start with well-cooked or steamed vegetables rather than raw salads.
Best Protein Sources
Lean proteins give your body what it needs to repair tissue without dumping excess fat into your stomach. The best choices are boneless, skinless chicken breast, turkey, white fish (cod, haddock, tilapia), and tofu. Tofu is especially neutral, with a pH around 7.2.
How you cook protein matters as much as what you choose. Steaming, boiling, poaching, and baking are all gentle preparation methods that keep fat content low. Frying adds fat that slows digestion and increases acid production. A poached chicken breast or a steamed fish fillet will sit much more comfortably in your stomach than the same protein breaded and fried.
Avoid fatty cuts of red meat, processed meats like sausage and bacon, and anything cooked in heavy oil or butter.
Grains and Starches
Plain whole grains are a staple of a gastritis-friendly diet. Oatmeal, brown rice, whole wheat bread, and plain pasta provide energy and fiber without irritating the stomach. White rice and plain crackers are even gentler options during an active flare when your stomach is most sensitive.
Fiber is helpful for gastritis in the long run, but timing matters. If your symptoms are intense, keep fiber intake moderate. As things improve, gradually increase fiber-rich foods to support overall digestive health and prevent further irritation. Jumping straight into high-fiber meals during a flare can make bloating worse.
Fermented Foods and Probiotics
Fermented foods contain probiotics, the beneficial bacteria that support a healthy gut. They’re especially worth including if your gastritis is caused by H. pylori, the bacterium responsible for many cases. Probiotics stimulate the growth of healthy flora that compete with harmful bacteria and may reduce the side effects of H. pylori infection.
Good probiotic-rich options include yogurt (choose low-fat varieties), kefir, sauerkraut, cottage cheese, and kombucha. If dairy-based yogurt bothers your stomach, coconut or almond-based yogurt with live cultures is a reasonable alternative.
What to Drink
Water is the simplest and safest choice. It has a neutral pH of about 7.0, helps move food through your digestive system, and mildly raises stomach pH. Unsweetened coconut water is another solid option that provides electrolytes and promotes pH balance.
Herbal teas can do double duty as both hydration and symptom relief. Chamomile, ginger, licorice root, and marshmallow root teas have all been used to soothe upper digestive discomfort. Ginger in particular has some of the stronger scientific evidence for easing gastrointestinal symptoms. Steep leaves or flowers for 5 to 10 minutes, or roots for 10 to 20 minutes, and aim for two to four cups a day.
If you drink juice, stick to low-acid varieties: carrot juice, aloe vera juice, cabbage juice, or fresh juices made from beets, watermelon, spinach, cucumber, or pear. Avoid orange juice, grapefruit juice, and any citrus-based drinks.
Plant-based milks like oat, almond, soy, and coconut milk tend to be lower in fat than dairy and are less likely to stimulate acid production. Full-fat cow’s milk, cream, and rich dairy products can increase gastric acid secretion and make symptoms worse.
Foods and Drinks to Avoid
Some foods reliably make gastritis worse by increasing acid production, slowing digestion, or directly irritating the stomach lining:
- Spicy foods: Chili peppers and hot sauces contain capsaicin, which stimulates excess gastric acid and can trigger flare-ups.
- Fried and fatty foods: These take longer to digest, keeping acid levels elevated for extended periods.
- Citrus fruits and juices: Oranges, lemons, limes, and grapefruits are too acidic for an inflamed stomach.
- Coffee and caffeinated drinks: Caffeine directly increases gastric acid secretion. This includes tea and energy drinks, not just coffee.
- Alcohol: It erodes the protective mucus layer of the stomach, causing direct inflammation. Heavy drinking can cause acute erosive gastritis on its own.
- Carbonated and sugary beverages: Sodas are high in both acid and sugar, which together increase acid production and digestive discomfort.
- Full-fat dairy: Whole milk, cream, and rich cheeses can stimulate excess acid. Low-fat or plant-based alternatives are better.
How to Eat: Timing and Portions
What you eat matters, but how you eat plays a surprisingly large role. Large meals place extra strain on the stomach, forcing it to produce more acid at once. Eating five or six smaller meals throughout the day instead of three large ones keeps your stomach from being overwhelmed.
Eat slowly and chew thoroughly. Rushing through a meal means your stomach has to work harder to break down food, which means more acid. Try not to eat within two to three hours of lying down, since a horizontal position makes it easier for acid to irritate the stomach lining.
Supplements and Nutrient Gaps
If you have autoimmune gastritis, your stomach may struggle to absorb iron and vitamin B12 from food. Over time, this can lead to iron-deficiency anemia or pernicious anemia (a B12 deficiency). Your doctor may recommend iron, folic acid, and B12 supplements. In cases where pernicious anemia has already developed, B12 injections are often necessary because oral supplements can’t be absorbed well enough through the damaged stomach lining.
Even without autoimmune gastritis, eating a restricted diet for weeks can leave nutritional gaps. Focus on variety within the safe food categories to make sure you’re getting enough vitamins and minerals. A daily multivitamin can help fill in the gaps while your diet is more limited than usual. One note of caution: iron supplements can, in rare cases, actually cause gastritis, so talk to your provider before starting them on your own.
A Typical Day of Eating
Putting it all together, a day of gastritis-friendly eating might look like this: oatmeal with sliced banana and a drizzle of honey for breakfast. A mid-morning snack of low-fat yogurt. Lunch of baked chicken breast with steamed carrots and brown rice. An afternoon snack of pear slices with a small handful of crackers. Dinner of poached cod with mashed sweet potatoes and steamed zucchini. Chamomile or ginger tea between meals.
None of this needs to be bland or boring. Herbs like basil, oregano, thyme, and parsley add flavor without irritating the stomach the way chili or black pepper can. A squeeze of lemon might be too acidic, but a little olive oil drizzled over vegetables after cooking adds richness without the problems that come with frying.
