Foods to Avoid with Acid Reflux: What to Eat

Why food matters for acid reflux

Ever notice how some days you can eat almost anything and feel fine, but other days even a small meal leaves your chest burning? 🤔 This guide breaks down the foods to avoid with acid reflux and what you can eat instead.

Acid reflux isn't only about how much acid your stomach makes. Certain foods relax the muscle at the bottom of the oesophagus, making it easier for acid to flow back up, while other foods push the stomach to produce more acid in the first place.

📊 According to Mayo Clinic, dietary changes can reduce acid reflux symptoms by more than 50% in people with mild cases — so choosing the right foods alone can make a real difference.

Foods to avoid

This group is the usual “culprit” behind most acid reflux flare-ups — check whether any of these are in your regular diet 👇

Fatty and fried food

Fried chicken, crispy pork, French fries — high-fat food slows digestion, so food sits in the stomach longer and more acid is produced. Fat also relaxes the muscle at the bottom of the oesophagus.

Spicy, heavily seasoned food

Som tam, tom yum, chilli dips — the spiciness irritates the oesophageal lining directly. Someone who already has reflux can end up with a burning chest for the rest of the day after one spicy meal.

Very sour food

Lime, orange, tomato, tomato sauce — their high acidity makes an already-irritated lining worse.

Chocolate and mint

Both relax the muscle at the bottom of the oesophagus, making reflux easier to happen — worth rethinking if you like chocolate after dinner.

Onion and raw garlic

Raw onion is a trigger many people overlook. The NHS notes that onion can clearly bring on heartburn.

Drinks that trigger acid

It's not just food — drinks can be just as big a trigger ☕

Coffee

Coffee relaxes the muscle at the bottom of the oesophagus, and drinking it on an empty stomach makes the burning worse. If you can't give it up, try a cold brew (lower acidity) or drink it after a meal instead.

Fizzy drinks

The carbon dioxide bubbles up the stomach, stretching it and pushing acid back up — this applies to both regular and sugar-free fizzy drinks.

Alcohol

Beer, wine and spirits relax the sphincter muscle and irritate the stomach lining — the more you drink, the worse it gets. The WHO lists alcohol as a major risk factor for digestive disease.

Sour fruit juices

Orange juice, lime juice, passion fruit juice — their high acidity triggers symptoms directly.

Foods that are easy on your stomach

The good news: plenty of foods are easy to eat comfortably — you don't have to give up everything 😊

Rice, bread and grains

Steamed rice, rice porridge, congee, wholewheat bread, oatmeal — these starchy foods digest easily and don't trigger acid. Oatmeal can even help absorb excess stomach acid.

Low-fat protein

Chicken breast, steamed fish, boiled eggs, tofu — choose steaming, boiling or baking over frying to cut the fat that triggers acid.

Boiled or steamed vegetables

Broccoli, carrots, green beans, pumpkin, water spinach — most vegetables are fine; just avoid ones cooked with a lot of oil.

Water, ginger tea and soy milk

Plain water is best. Ginger tea helps ease nausea and soothes irritation. Soy milk is a good alternative to cow's milk, which can trigger acid in some people.

Fruit: what you can eat and what to avoid

Fruit is a category that confuses a lot of people — some kinds are fine, others cause burning right away.

Simple rule: mildly sweet, non-sour fruit is fine; very sour fruit is best avoided.

Eating habits that keep your stomach calm

Besides “what to eat,” “how you eat” matters just as much.

Eat small meals, more often

Instead of 3 large meals, try splitting them into 4-5 smaller ones. The stomach doesn't have to work as hard, so it produces less acid.

Don't eat late, and don't lie down right after eating

Eat your last meal at least 2-3 hours before bed — lying down while the stomach is still full makes reflux much more likely.

Chew slowly, don't rush

Chewing food thoroughly helps the stomach digest it more easily, which reduces excess acid production.

Don't drink a lot of water during meals

A few sips are fine, but avoid drinking large amounts of water while eating, as it stretches the stomach.

Sample one-day menu

Here's an example of a day's menu that most people with acid reflux can eat comfortably 🍽️

Breakfast: Chicken congee + a boiled egg + warm ginger tea

Morning snack: 1 small banana

Lunch: Steamed rice + lime-steamed fish (just a touch of lime) + clear tofu and vegetable soup

Afternoon snack: Sliced apple + oatmeal with soy milk

Dinner (before 9pm): Rice congee with fish + boiled vegetables
