Gastroesophageal reflux disease (GERD) occurs when stomach acid repeatedly flows back into the esophagus, usually because the lower esophageal sphincter (LES), the ring of muscle that should keep stomach contents where they belong, relaxes or weakens at the wrong times. The result is the burning sensation known as heartburn, along with regurgitation, chest discomfort, and sometimes a chronic cough or sore throat. Harvard Health Publishing notes that dietary change may be all that is necessary for people with infrequent and mild GERD, while more frequent or severe cases are more likely to also need medication.
It is worth knowing that the foods people report as symptom triggers are not always the same foods that contribute to developing GERD in the first place. A 15-year prospective cohort study following over 15,000 adults found that higher fat intake and more frequent carbonated beverage consumption were associated with increased risk of developing GERD, while total fruit and citrus intake were associated with reduced risk, even though citrus is commonly blamed as a symptom trigger. The researchers concluded that foods conventionally considered triggers of GERD symptoms might not necessarily be the same foods that contribute to the disease developing in the first place. This is why a generic avoid-list works for some people but not others, and why tracking your own reactions matters more than following any list exactly.

How Diet Triggers and Calms Acid Reflux
Certain foods relax the LES itself. Fat, chocolate, caffeine, alcohol, and peppermint have all been shown to loosen the lower esophageal sphincter, making it easier for stomach acid to escape upward regardless of how much you ate.
Gas and pressure push acid upward. Carbonated beverages were associated with increased GERD risk and are a commonly cited symptom trigger because the carbon dioxide they release increases belching and promotes inappropriate relaxation of the LES.
Fiber supports the mechanical barrier against reflux. A controlled study in patients with non-erosive reflux disease found that supplementing a low-fiber diet with psyllium fiber for just ten days significantly increased minimal LES resting pressure, reduced the total number of reflux episodes, and cut the proportion of patients experiencing heartburn from 93% to 40%.
Excess weight increases pressure on the stomach. A randomized clinical trial found that a six-month individualized weight loss diet produced significantly greater improvement in GERD symptoms and quality of life scores than standard dietary guidance alone, with symptom improvement directly correlated to the amount of weight lost.
Sugar and refined carbohydrate intake may matter more than fat alone. <a href="https://journals.lww.com/ajg/fulltext/2022/10000/theeffectsofmodifyingamountandtype_of.24.aspx”>A study published in the American Journal of Gastroenterology found that reducing simple sugar intake by roughly 62 grams per day produced significantly greater improvement in heartburn and chest discomfort than a standard diet, even when total fat, fiber, and carbohydrate intake were held constant between groups.
GERD Diet Foods List: What to Buy
High-Fiber Foods (Most Important Category)
Fiber supports gastric motility, helps maintain a healthy weight, and forms a gel-like substance in the stomach that may physically reduce how easily acid refluxes upward.
Best sources:
- Oatmeal (a gentle, low-fat breakfast that absorbs acid and adds bulk)
- Brown rice and quinoa (steady, low-fat complex carbohydrate)
- Whole grain bread, in moderation
- Lentils and beans, introduced gradually if you are not used to a high-fiber diet
- Psyllium husk, stirred into water or a smoothie if your diet is currently low in fiber
- Sweet potatoes
- Most vegetables, especially leafy greens, broccoli, carrots, and green beans
Lean, Minimally Processed Proteins
Lean proteins are far less likely to relax the LES than fatty or fried preparations of the same protein, making cooking method as important as the protein choice itself.
Best sources:
- Chicken breast and turkey, skinless and grilled, poached, or baked rather than fried
- Fresh white fish such as cod, tilapia, or halibut
- Egg whites (lower fat than whole eggs, which some people with GERD tolerate less well)
- Lentils, beans, and tofu
Non-Citrus Fruits (and Citrus, Tested Individually)
Most fruits are low in fat and well tolerated. Citrus is the most individualized item on this list: it is commonly self-reported as a symptom trigger, yet the same large cohort study found total fruit and citrus intake were both associated with reduced risk of developing GERD over time, so the right approach is testing your own tolerance rather than assuming it must be avoided.
Best choices:
- Bananas
- Melon, all varieties
- Apples and pears
- Berries
Most Vegetables
Vegetables are naturally low in fat and high in fiber, making them one of the most broadly well-tolerated food categories for GERD.
Best choices:
- Leafy greens
- Broccoli and cauliflower, well tolerated by most people despite being cruciferous
- Carrots and green beans
- Sweet potatoes
- Cucumber and zucchini
Ginger and Soothing Foods
A review of functional foods for GERD found that some foods possess soothing properties that may help protect the esophageal lining, including marshmallow root and slippery elm, which contain mucilage that forms a gel-like coating against acid exposure.
Best choices:
- Fresh ginger, added to tea or cooking (traditionally used to settle the stomach)
- Marshmallow root tea
- Slippery elm, taken as a tea or lozenge
Healthy Fats, in Moderation
Fat is not entirely off the table, but portion size matters far more for fat than for most other food categories on a GERD diet.
Best choices, in modest portions:
- Olive oil, used in small amounts rather than poured liberally
- Avocado, in moderation
- Walnuts and almonds, in small portions
Low-Fat Dairy and Alternatives
- Low-fat or skim milk
- Low-fat yogurt, plain
- Unsweetened almond or oat milk
Foods to Avoid With GERD and Acid Reflux
High-Fat and Fried Foods
High-fat foods slow stomach emptying and relax the LES, both of which make reflux more likely after a meal.
Foods to avoid or limit:
- Fried foods of all kinds
- Fast food
- Full-fat cream sauces and gravies
- Fatty cuts of red meat and bacon
- Whole-milk dairy products in large amounts
Carbonated Beverages
The Melbourne Collaborative Cohort Study found that more frequent carbonated beverage consumption was associated with increased risk of developing GERD, consistent with their well-established role as a symptom trigger.
Foods and beverages to avoid:
- Soda, regular and diet
- Sparkling water, if you notice it triggers symptoms
- Beer and other carbonated alcoholic beverages
Caffeine and Alcohol
Both caffeine and alcohol relax the LES and can increase stomach acid production, a combination that makes them two of the most consistently reported GERD triggers.
Foods and beverages to avoid or limit:
- Coffee, including decaf for some individuals
- Black and green tea
- Energy drinks
- Wine, beer, and spirits
Chocolate and Peppermint
Foods to avoid:
- Chocolate and cocoa products
- Peppermint tea and peppermint candy
Spicy Foods
Foods to avoid or test individually:
- Hot peppers and chili-based dishes
- Foods heavily seasoned with black pepper, cayenne, or chili powder
Added Sugars and Refined Carbohydrates
Reducing simple sugar intake specifically, rather than just total carbohydrate or fat, has shown a meaningful symptom benefit in controlled research, making this category worth limiting even when fat intake is already under control.
Foods to limit:
- Candy, pastries, and sweetened baked goods
- Sugar-sweetened beverages
- White bread, white pasta, and other refined-grain products in large portions
Acidic Foods, Tested Individually
Tomato products and citrus are the most commonly self-reported acidic triggers, but individual tolerance varies considerably, and some research suggests these foods are not the universal problem they are often assumed to be.
Foods to test individually:
- Tomato sauce and other concentrated tomato products
- Citrus fruits and juices
- Vinegar-based dressings and condiments

Practical Tips for Managing Acid Reflux Through Diet
Identify your own triggers rather than eliminating everything at once. Because individual tolerance varies so much, especially for citrus, tomato, and chocolate, a brief elimination followed by reintroducing foods one at a time will tell you more about your personal triggers than any general list.
Eat smaller, more frequent meals. A large meal stretches the stomach and increases pressure against the LES, making reflux more likely regardless of what you ate.
Avoid lying down for at least three hours after eating. Gravity helps keep stomach contents down, so finishing dinner well before bedtime is one of the simplest and most effective changes available.
Limit fat per meal rather than eliminating it entirely. Since fat relaxes the LES and slows digestion, spreading smaller amounts of fat across the day tends to work better than one large fatty meal.
Work toward a healthy weight if you are overweight. A randomized clinical trial found that intentional weight loss through dietary counseling produced significant, measurable improvement in both GERD symptoms and quality of life over six months.
Keep a food and symptom journal. Tracking what you eat alongside when symptoms occur is the most reliable way to separate true personal triggers from foods that are commonly blamed but may not actually affect you.
See your doctor for persistent or severe symptoms. Frequent GERD that does not respond to dietary changes can lead to complications such as esophagitis or Barrett’s esophagus and may require medication or further evaluation.
The Bottom Line
A GERD diet works by addressing several mechanisms at once: avoiding foods that relax the lower esophageal sphincter, reducing gas-producing and high-fat foods that increase stomach pressure, and building meals around fiber-rich foods that support gastric motility and a healthy weight. Fill your grocery cart with high-fiber whole grains and vegetables, lean and gently cooked proteins, most fruits, and modest portions of healthy fat, while limiting fried and fatty foods, carbonated beverages, caffeine, alcohol, chocolate, and added sugars. Because research shows that commonly blamed trigger foods like citrus do not affect everyone the same way, pair this grocery list with your own food and symptom journal to find out exactly which foods matter for you.
