If you frequently experience heartburn, acid reflux, or GERD (gastroesophageal reflux disease), you understand the discomfort it brings. While medication can help, your diet significantly influences symptom management. A well-structured acid reflux diet meal plan can serve as a roadmap to identify trigger foods, alleviate symptoms, and promote overall digestive health.
Understanding Acid Reflux and GERD
Acid reflux occurs when stomach acid flows back up into the esophagus, the tube connecting your mouth to your stomach. Heartburn, a burning sensation in the chest, is a common symptom of acid reflux. When acid reflux happens frequently over long periods of time, it can lead to gastroesophageal reflux disease (GERD). GERD is a chronic gastrointestinal condition with frequent acid reflux over a long period of time. It may or may not include heartburn as a symptom. Common symptoms of GERD include backwash of food into the mouth, burning in the throat or chest (heartburn), nausea, and a sore throat.
In people with frequent heartburn, the lower esophageal sphincter muscle (LES) may be weak, or relax too frequently, allowing stomach acids to get into the esophagus. The lower esophageal sphincter is a valve that separates your esophagus from your stomach. This valve manages the downward flow of food and drink through your upper GI tract, and GERD is a signal that the valve isn’t doing its job properly.
The Role of Diet in Managing GERD
The food we eat is only supposed to travel down through the digestive system. Swallowed food moves through a tube in the throat called the esophagus and down into the stomach. Therefore, a GERD diet typically involves limiting foods that can cause the LES to relax, such as fatty foods and spicy foods. Acidic foods, caffeine, and alcohol can also be triggers for certain people.
Dietary changes can play a crucial role in managing GERD symptoms by reducing exposure to trigger foods and increasing intake of foods that promote a healthy gastrointestinal (GI) tract.

Key Principles of an Acid Reflux Diet
The primary goal of an acid reflux diet is to minimize symptoms by avoiding foods and beverages that trigger acid production or weaken the LES. Here are some general principles to follow:
- Avoid Trigger Foods: Identify and eliminate foods that worsen your symptoms. Common culprits include fatty and fried foods, spicy foods, citrus fruits and juices, tomato-based products, chocolate, caffeine, alcohol, onions, and peppermint.
- Eat Smaller, More Frequent Meals: Large meals can increase stomach pressure and the likelihood of acid reflux. Try eating four to five small meals instead of two or three large ones.
- Avoid Late-Night Eating: Refrain from eating at least 3 hours before you lie down or go to bed at night. This helps prevent backflow of acid into the esophagus and can reduce overnight reflux symptoms.
- Stay Upright After Eating: Avoid lying down for two to three hours after eating. When you lie down, it's physically easier for stomach contents to splash up toward the LES. By sitting up or standing, gravity helps stomach contents stay where they belong -- at the bottom of the stomach.
- Maintain a Healthy Weight: Plan your meals to encourage slow but sure weight loss if you are overweight. Extra weight around the midsection, especially, can press against the stomach and increase the pressure going up toward the LES.
- Elevate Your Head While Sleeping: Sleeping with the head of the bed elevated can also help prevent the backflow of acid.
- Chew Gum: Chew gum (a nonpeppermint flavor) after meals to stimulate saliva production (the bicarbonate in saliva neutralizes acid) and increase peristalsis (which helps move the stomach contents into the small intestine more quickly).
- Eat a High Fiber Diet: A recent study found that people who followed a high-fiber meal plan were 20% less likely to have acid reflux symptoms, regardless of their body weight. You'll find fiber in whole grains, fruits, vegetables, beans, nuts and seeds (basically unprocessed plant foods).
Foods to Avoid
- Fatty and Fried Foods: These foods can weaken the LES muscle and stay in the stomach longer, increasing the risk of reflux. Examples include fast food, potato chips, bacon, and sausage.
- Spicy Foods: Spicy foods can irritate the esophagus lining.
- Citrus Fruits and Juices: These can irritate a damaged esophagus.
- Tomato-Based Products: Like citrus, tomatoes are acidic and can worsen symptoms.
- Chocolate: Chocolate can weaken the LES muscle.
- Caffeine: Coffee (even decaf), caffeinated tea, and cola can increase the acid content in the stomach as well as relax the LES.
- Onions: Onions can trigger heartburn in some individuals.
- Peppermint: Peppermint can weaken the LES muscle.
- Carbonated Drinks: Sodas can bloat the abdomen, increasing the pressure in the stomach and encouraging stomach acid to splash up into the esophagus.
- Alcoholic Beverages: Alcohol can increase the acid content in the stomach as well as relax the LES.
Foods to Include
- High-Fiber Foods: These can fill you up and promote healthy digestion. Examples include whole grains, fruits, and vegetables.
- Lean Proteins: Chicken breast and fish are good options to lower the fat in your meals.
- Non-Citrus Fruits: Melons and bananas are less likely to trigger symptoms.
- High Water Content Foods: Cucumber, lettuce, and broth-based soups can help dilute stomach acid.
- Milk: Milk can help buffer stomach acid, although some people can be sensitive to lactose.
- Ginger: Ginger can soothe gut irritation.
Sample 7-Day GERD Diet Meal Plan
This meal plan provides a general framework. Remember to adjust it based on your individual triggers and preferences.
Day 1
- Breakfast: Low-acid fruit smoothie (banana, almond milk, honey) and oatmeal with cinnamon.
- Lunch: Grilled chicken salad with mixed greens and light vinaigrette (or olive oil and herbs), vegetable soup (carrot, potato, or chicken broth), and a slice of whole-grain bread.
- Dinner: Baked salmon with steamed broccoli and quinoa.
- Snacks: Low-acid fruit plate (melons, pears) with cheese cubes and whole-grain crackers.
- Dessert: Yogurt with a drizzle of honey (choose lactose-free if needed).
Day 2
- Breakfast: Scrambled eggs on a whole-grain English muffin topped with avocado slices.
- Lunch: Turkey wrap (whole-grain tortilla, roasted turkey, lettuce, cucumbers, basil) and butternut squash soup.
- Dinner: Grilled chicken breast with brown rice and steamed green beans.
Beverages to Encourage
- Water
- Mineral Water
- Decaffeinated Tea
- Non-Citrus Juices
- Nonfat or Low-Fat Milk
Lifestyle Modifications
In addition to dietary changes, certain lifestyle modifications can help manage GERD symptoms:
- Quit Smoking: Tobacco can have a negative effect on saliva production.
- Reduce Alcohol Consumption: Alcohol can worsen GERD symptoms.
- Wear Loose Clothing: Tight belts and waistbands can increase abdominal pressure, contributing to GERD.
- Manage Stress: The brain and the gut are connected via the gut-brain axis. Stress can trigger or worsen GERD symptoms. Consider stress-reducing techniques like meditation or yoga.
- Wait Before Exercising: Try waiting at least two hours after a meal before exercising if you find your heartburn seems to get worse after exercise.
Addressing the Gut-Brain Connection
The brain and the gut are connected via what’s called the gut-brain axis. “Many people also suffer stress from the long-term impact of having had adverse childhood experiences (ACEs),” says David D. “ACEs can cause the development of stressful personality traits, triggers in your present-day life, and unrecognized but powerful negative emotions,” he adds. ACEs change the body’s natural stress response and may cause visceral hypersensitivity, which is when the usual functioning of your organs causes unexplained pain. Some people experiencing reflux may have reflux hypersensitivity. In these cases, a person may experience GERD symptoms, such as heartburn, but they have normal test results.
GERD vs. IBS: Is There a Connection?
While gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS) are different conditions, research suggests that there is some overlap between the two. IBS is diagnosed when abdominal pain is present along with altered bowel habits, such as constipation or diarrhea. In contrast, GERD causes pain and discomfort in the chest, esophagus, and throat.

It’s suggested that a change in gut motility (the movement of the digestive tract) may be involved in both GERD and IBS. Additionally, hypersensitivity of the gut and issues with the gut-brain connection are also areas of similarity. Some people may have both IBS and GERD at the same time.
Seeking Professional Guidance
Everyone’s tolerance to different foods can vary, so working with a registered dietitian can help you determine your individual triggers. A dietitian can be particularly effective by helping you evaluate your overall diet and identify what triggers acid reflux for you. Your dietitian will put together a plan that includes removing certain foods for a period of time and then slowly reintroducing them one by one to find out what works best for you.
If you’re experiencing symptoms of acid reflux or GERD, it’s essential to talk to your doctor. They can provide you with a comprehensive treatment plan, which often includes a GERD diet to help manage and reduce symptoms. Gastroenterologists can offer medications and surgical procedures that can help even severe GERD. For example, the GERD and Heartburn Clinic at Newton-Wellesley Hospital is one of only a few interdisciplinary GERD clinics in the country.
