Acid Reflux Prevention: What Foods Help with Heartburn?

That burning sensation in your chest after eating may be more than simple indigestion. Acid reflux is a common digestive issue affecting many Australians and can interfere with sleep, meals, exercise, and daily comfort.

The good news? For many people, simple changes to diet and lifestyle can significantly reduce symptoms and improve quality of life.

Read on to learn what acid reflux is, which foods may help, which foods may trigger symptoms, and when it may be time to seek medical advice.

What Is Acid Reflux?

Acid reflux occurs when stomach contents flow backward into the oesophagus (food pipe). This happens when the lower oesophageal sphincter — a ring-like muscle that normally prevents stomach acid from travelling upward — becomes weak or relaxes inappropriately.

When acid irritates the lining of the oesophagus, it can cause symptoms such as:

• Heartburn (a burning sensation in the chest)
• Sour or bitter taste in the mouth
• Regurgitation of food or acid
• Bloating or burping
• Nausea
• Chronic cough or throat irritation

When reflux occurs frequently or causes complications, it may be diagnosed as gastro-oesophageal reflux disease (GORD). GORD is common in Australia and can range from mild, occasional discomfort to more persistent symptoms requiring medical treatment.

Foods That May Help Reduce Acid Reflux

While no single food can "cure" acid reflux, some foods are generally easier on the stomach and may help reduce symptoms.

Ginger

Ginger has natural anti-inflammatory properties and may help settle the digestive system. Some people find ginger tea soothing when experiencing reflux symptoms.

Oatmeal

Oatmeal is high in fibre and can be a gentle, filling breakfast option. Fibre may help digestion and reduce overeating, which can worsen reflux.

Bananas

Bananas are naturally low in acidity and are often well tolerated by people prone to heartburn.

Melons

Melons such as cantaloupe and honeydew are low-acid fruits that may be easier on the stomach than citrus fruits.

Green Vegetables

Vegetables such as spinach, broccoli, kale, beans, cucumber, and zucchini are nutritious, low in fat, and generally less likely to trigger reflux symptoms.

Lean Proteins

Lean protein sources such as skinless chicken, turkey, fish, tofu, and eggs are often easier to digest than heavily processed or fatty meats.

Healthy Fats (in Moderation)

Small amounts of healthy fats such as olive oil, nuts, seeds, and avocado may fit into a balanced diet, although large high-fat meals can worsen reflux in some people.

Foods That May Trigger Heartburn

Reflux triggers vary from person to person. However, certain foods commonly worsen symptoms by increasing stomach acid or relaxing the lower oesophageal sphincter. Common triggers include:

Spicy Foods

Chilli, hot sauce, curry, and heavily spiced meals can irritate the oesophagus and worsen burning symptoms.

Citrus Fruits

Oranges, lemons, limes, and grapefruit are acidic and may aggravate reflux.

Tomatoes and Tomato-Based Foods

Tomato sauces, salsa, and ketchup are common reflux triggers.

Fried and Fatty Foods

Fast food, deep-fried meals, creamy sauces, and heavy takeaway meals may delay stomach emptying and worsen reflux.

Caffeine and Carbonated Drinks

Coffee, energy drinks, cola, and fizzy drinks may worsen reflux in some individuals.

Chocolate

Chocolate may relax the lower oesophageal sphincter and trigger symptoms in susceptible people.

Alcohol

Alcohol can irritate the digestive tract and increase reflux symptoms.

Onions and Garlic

These foods can trigger bloating and worsen reflux in some people.

Peppermint and Spearmint

Although mint may soothe digestion in some situations, it can worsen reflux by relaxing the oesophageal sphincter.

Other Ways to Prevent Acid Reflux

Diet is only one part of reflux management. Lifestyle habits can also make a significant difference.

Eat Smaller Meals

Large meals place extra pressure on the stomach and can trigger reflux.

Avoid Eating Late at Night

Try to finish meals at least 2–3 hours before lying down or going to bed.

Maintain a Healthy Weight

Carrying excess weight, particularly around the abdomen, increases pressure on the stomach and raises reflux risk.

Elevate the Head of the Bed

Sleeping with your upper body slightly elevated may reduce nighttime reflux.

Avoid Tight Clothing

Tight waistbands can increase abdominal pressure and worsen symptoms.

Avoid Vigorous Exercise Straight After Meals

Gentle walking after meals may aid digestion, but high-intensity exercise, bending, or abdominal workouts soon after eating may trigger reflux.

Avoid Smoking

Smoking weakens the lower oesophageal sphincter and increases reflux risk.

When Should You Speak to a Doctor?

Occasional reflux is common and often improves with lifestyle changes or over-the-counter medications such as antacids.

However, persistent or worsening symptoms should not be ignored. Speak to your doctor if you experience:

• Heartburn more than twice per week
• Symptoms that keep returning despite treatment
• Difficulty swallowing
• Persistent nausea or vomiting
• Chronic cough, hoarse voice, or throat irritation
• Sleep disturbance due to reflux
• Unexplained weight loss

Persistent reflux symptoms may require further investigation to rule out other causes or contributing conditions. Your doctor may assess for alternative diagnoses or underlying conditions such as:

• Infection with a bacteria called Helicobacter pylori (H. pylori)
• Hiatal hernia
• Gastritis
• Peptic ulcer disease
• Oesophagitis
• Barrett's oesophagus
• Gallbladder disease
• Functional dyspepsia

Investigations may include breath or stool testing for H. pylori, blood tests, imaging, or referral for endoscopy depending on symptoms and risk factors.

Final Thoughts

Acid reflux can be uncomfortable and disruptive, but many people find meaningful relief with simple changes to diet and lifestyle. Identifying your personal trigger foods, eating smaller meals, maintaining a healthy weight, and seeking early medical advice for persistent symptoms can all help.

While occasional heartburn is common, ongoing reflux should not be ignored — especially if symptoms persist despite treatment or interfere with your daily life. Early assessment can help identify underlying causes and reduce the risk of long-term complications.
