Bananas, melons, oatmeal, ginger tea, and plain water can all help relieve heartburn by either neutralizing stomach acid or reducing the pressure that pushes it upward. The best long-term strategy combines these soothing choices with avoiding the foods that trigger reflux in the first place.
Alkaline Foods That Offset Stomach Acid
Every food sits somewhere on the pH scale. Lower-pH foods are more acidic and more likely to trigger reflux, while higher-pH (alkaline) foods help counterbalance the acid in your stomach. The most accessible alkaline options are bananas, melons (cantaloupe, honeydew, watermelon), cauliflower, fennel, and nuts. These are easy to keep on hand and work well as snacks or side dishes when heartburn is flaring.
Bananas and melons are especially practical because they’re mild, require no preparation, and rarely bother anyone’s stomach. Citrus fruits like oranges, grapefruits, and lemons sit on the opposite end of the spectrum. If citrus consistently triggers your symptoms, swapping it for one of these gentler fruits is a straightforward fix.
Why Fiber Deserves a Starring Role
High-fiber foods may be the single most underrated tool for heartburn relief. In a clinical study of people with non-erosive reflux disease, switching to a fiber-enriched diet cut the number of people experiencing heartburn from 93% to 40%. Sixty percent of participants saw their heartburn resolve completely within the study period. The benefit appears to be physical: fiber strengthens the resting pressure of the valve between your esophagus and stomach, making it harder for acid to escape upward. It also improves gut motility, so food moves through your stomach faster rather than sitting there and generating more acid.
Epidemiological data shows the effect is dose-dependent, meaning the more fiber you eat, the lower your risk of heartburn. Good sources include oatmeal, brown rice, whole-grain bread, sweet potatoes, carrots, beets, and green vegetables like broccoli and asparagus. If your current diet is low in fiber, increasing it gradually over a week or two helps avoid bloating while you adjust.
Ginger: A Natural Anti-Reflux Option
Ginger has a long track record as a digestive aid, and the science supports it. The active compounds in ginger root reduce pressure on the lower esophageal sphincter (the valve that keeps acid in your stomach), ease intestinal cramping, and help prevent bloating and gas. These effects make it useful both during an active bout of heartburn and as a regular part of your diet.
Fresh ginger sliced into hot water makes a simple tea. You can also grate it into soups, stir-fries, or smoothies. While no specific dose has been established for reflux, studies on related digestive symptoms have used around 1,500 mg per day (roughly a one-inch piece of fresh root), split across meals. Stick to whole ginger root or ginger tea rather than ginger ale, which is carbonated and often contains very little actual ginger.
What to Drink for Quick Relief
Plain water works faster than most people expect. In a study of healthy subjects, a single glass of water raised stomach pH above 4 (the threshold where acid stops being irritating) within one minute. The catch is that this effect only lasts about three minutes, so water is best thought of as immediate, temporary relief rather than a lasting solution. Sipping water between meals, rather than gulping large amounts during a meal, keeps your stomach from overfilling, which is a common reflux trigger.
Herbal teas offer a longer window of comfort. Chamomile tea has a soothing effect on the digestive tract, though people with ragweed allergies should be cautious since cross-reactions are possible. Fennel tea and marshmallow root tea are also traditionally used for heartburn relief. One important note: skip peppermint tea if reflux is your problem. Peppermint relaxes the lower esophageal sphincter, which can actually make acid escape more easily.
The Truth About Milk
Milk feels cool and coating going down, which is why so many people reach for it during heartburn. But the research tells a more complicated story. A randomized controlled trial found that increasing dairy intake to three or more servings per day had no measurable effect on heartburn or acid regurgitation, regardless of whether the dairy was low-fat or full-fat. Broader data links high dairy consumption and dietary fat with worse reflux symptoms over time. A small glass of cold milk may soothe the moment, but it’s not a reliable treatment strategy.
Chewing Gum After Meals
This one sounds too simple to work, but chewing sugar-free gum after eating roughly doubles your saliva production. Saliva is naturally alkaline, and that extra flow washes acid back down out of the esophagus. In one study, chewing gum cut the time it took for esophageal acid to clear from nearly seven minutes down to about two and a half minutes. Keep a pack of sugar-free gum handy and chew for 20 to 30 minutes after a meal, particularly dinner.
Foods and Drinks to Avoid
What you remove from your plate matters as much as what you add. The American College of Gastroenterology identifies several common triggers worth limiting or eliminating:
- Carbonated beverages increase stomach pressure and have moderate scientific evidence linking them to reflux
- High-fat meals slow gastric emptying, keeping acid-producing food in your stomach longer
- Chocolate relaxes the esophageal sphincter
- Spicy foods directly irritate the esophageal lining
- Tomatoes and tomato-based sauces are highly acidic
- Coffee can trigger symptoms in some people, though the evidence for switching to decaf is mixed
Alcohol has a weak but real association with reflux, and different types of alcohol affect people differently. If beer consistently bothers you but wine doesn’t, trust your own experience over blanket advice.
Timing and Portion Size
Even the right foods can cause problems if you eat too much or too late. Eating smaller meals reduces the volume pressing against your esophageal sphincter, making reflux physically less likely. The ACG recommends finishing your last meal at least two to three hours before lying down. This gives your stomach time to empty while gravity is still helping keep acid where it belongs.
If nighttime heartburn is your main issue, sleeping on your left side positions your stomach below your esophagus, making it harder for acid to travel upward. This recommendation has the strongest level of scientific evidence among all lifestyle modifications for reflux. Elevating the head of your bed by six to eight inches (using a wedge pillow or bed risers, not just extra pillows) adds another layer of protection.
