Certain foods and drinks can ease heartburn within minutes, while others help prevent it from happening in the first place. The key is choosing items that either neutralize stomach acid, strengthen the muscular valve between your stomach and esophagus, or move through your digestive system quickly. Here’s what actually works.
Alkaline Fruits That Neutralize Acid
Bananas, melons, and watermelon are naturally alkaline, meaning they help counteract the acid that splashes up into your esophagus during a heartburn episode. Bananas in particular are easy to keep on hand and gentle enough to eat even when your chest is already burning. Melons and watermelon have high water content, which further dilutes stomach acid.
Citrus fruits like oranges, grapefruits, and lemons do the opposite. They’re highly acidic and can trigger or worsen symptoms. If you enjoy fruit but get frequent heartburn, stick with the non-citrus options: bananas, cantaloupe, honeydew, and watermelon are all safe choices.
Lean Proteins Over Fatty Meats
High-protein foods like lean chicken, fish, eggs, tofu, and legumes increase the pressure of the lower esophageal sphincter (LES), the valve that keeps stomach contents from rising up. Stronger pressure at this valve means less acid escapes into your esophagus. Protein also promotes stomach emptying, so food doesn’t sit around generating acid for as long.
Fatty foods do the opposite. Bacon, sausages, burgers, fried foods, and full-fat dairy products reduce LES pressure and slow stomach emptying, giving acid more time and opportunity to creep upward. If you’re dealing with heartburn regularly, swapping a fried chicken breast for a grilled one or choosing baked fish over a burger can make a noticeable difference.
What to Drink for Quick Relief
Plain water is the simplest option. It dilutes stomach acid and washes any acid that’s already in your esophagus back down. Alkaline water with a pH of 8.8 may go a step further. A study published in the Annals of Otology, Rhinology & Laryngology found that water at this pH permanently deactivated pepsin, a stomach enzyme that damages esophageal tissue during reflux. Alkaline water also had eight times the acid-buffering capacity of regular bottled water. You can find pH 8.8 water at most grocery stores.
Chamomile tea can have a soothing effect on the digestive tract, and licorice tea is thought to increase the protective mucous coating of the esophageal lining, helping it resist acid irritation. Both are caffeine-free, which matters because caffeine can relax the LES and make reflux worse. Skip coffee, regular tea, carbonated drinks, and alcohol when heartburn is active.
The Truth About Milk
Reaching for a glass of milk when heartburn strikes is a common instinct, but the answer is complicated. Skim or low-fat milk can provide short-term relief because its calcium and protein help neutralize stomach acid and tighten the LES. Full-fat milk, on the other hand, tends to make symptoms worse because of its fat content.
There’s a catch even with skim milk. The protein in milk stimulates gastrin, a hormone that strengthens the LES and speeds stomach emptying (both good), but also increases stomach acid production (not good). So milk may soothe the burn initially, then trigger a rebound wave of acid shortly after. If you find milk helps you, stick with skim or low-fat versions. If it seems to make things worse after 20 to 30 minutes, a plant-based milk alternative may be a better fit.
Ginger in Small Amounts
Ginger has anti-inflammatory properties that can reduce irritation in the esophagus and calm stomach acid production in small doses. You can peel fresh ginger root and steep slices in boiling water for about 15 minutes to make ginger tea, grate it into soups or stir-fries, or take it as a quick ginger shot.
The key word is “small.” Too much ginger can backfire and cause stomach upset on its own. Start with a small cup of ginger tea after a meal and see how your body responds. If you’re considering ginger supplements (capsules or concentrated extracts), be aware these can interact with certain medications, so they’re worth discussing with your doctor first.
Chewing Gum After Meals
This one surprises most people: chewing sugar-free gum for 30 minutes after eating significantly reduces heartburn. A study from King’s College London found that gum chewing cut the time acid spent in the esophagus nearly in half. Participants who chewed gum after a reflux-triggering meal had acid exposure of 3.6% compared to 5.7% without gum.
The mechanism is straightforward. Chewing stimulates saliva production, and saliva is naturally alkaline. Swallowing that saliva more frequently washes acid out of the esophagus and neutralizes what remains. Any sugar-free gum works. Avoid mint flavors if peppermint is one of your personal triggers, as it relaxes the LES in some people.
Timing Matters as Much as Food Choice
Even the most heartburn-friendly meal can cause problems if you lie down right after eating. When you’re horizontal, gravity can no longer help keep stomach contents where they belong. The standard recommendation is to wait at least two to three hours after eating before lying down or going to sleep. This gives your stomach enough time to begin emptying.
Smaller, more frequent meals also help. A large meal stretches the stomach and puts pressure on the LES, making it easier for acid to push through. Eating a moderate portion and stopping before you’re stuffed reduces that pressure. If heartburn is a recurring nighttime problem, making dinner your lightest meal and eating it earlier in the evening often provides the most relief of any single change.
Foods and Drinks to Avoid
Knowing what helps is only half the equation. These common triggers relax the LES, increase acid production, or directly irritate the esophagus:
- Fried and high-fat foods: slow stomach emptying and weaken the LES
- Citrus fruits and juices: highly acidic and irritating to damaged tissue
- Tomatoes and tomato-based sauces: acidic and a frequent trigger
- Coffee and caffeinated drinks: relax the LES
- Alcohol: relaxes the LES and increases acid production
- Carbonated beverages: increase stomach pressure through gas buildup
- Chocolate: contains compounds that relax the LES
- Spicy foods: can irritate an already inflamed esophagus
Not everyone reacts to every item on this list. Paying attention to your own patterns is more useful than avoiding everything preemptively. If tomato sauce doesn’t bother you, there’s no reason to eliminate it. But if you’re having heartburn several times a week and can’t identify a cause, cutting these out temporarily and reintroducing them one at a time can help you pinpoint your personal triggers.
