Acid reflux, a prevalent health concern, is often triggered by dietary choices. Among the commonly implicated foods, a frequently asked question is, “Are onions bad for acid reflux?” This article aims to unpack the relationship between onions and acid reflux, and explore whether different types of onions affect acid reflux differently.
Understanding Acid Reflux
Acid reflux, also known as gastroesophageal reflux disease (GERD), is a common condition impacting the digestive system. It involves the regurgitation of stomach acid and sometimes partially digested food back into the esophagus (the tube that connects your mouth to your stomach).
This can happen when the lower esophageal sphincter (LES), a ring of muscle acting as a one-way valve at the bottom of the esophagus, doesn’t close properly or opens too often. The LES is supposed to close as soon as food passes through it to prevent stomach acid from rising into the esophagus.
The primary symptom of acid reflux is heartburn, which is a burning sensation that can rise from your stomach up to your chest and even up to your throat. Other common symptoms include regurgitation of food or sour liquid, difficulty swallowing, feeling like you have a lump in your throat, chronic cough, laryngitis, or disrupted sleep.
When acid reflux symptoms occur more than twice a week, it is usually considered GERD, a more chronic, severe form of acid reflux. Long-term, unmanaged GERD can lead to serious complications such as esophagitis (inflammation, irritation, or swelling of the esophagus), esophageal stricture (narrowing of the esophagus), respiratory problems, or Barrett’s esophagus. Barrett’s esophagus is a serious complication where the cells of the esophagus take on an abnormal shape and color, which can increase the risk of esophageal cancer.

Acid reflux is usually managed through lifestyle modifications and over-the-counter medications. Lifestyle changes can include dietary alterations (like avoiding trigger foods), losing weight if overweight, quitting smoking, reducing alcohol consumption, and not eating within two to three hours before bedtime. Over-the-counter remedies include antacids, H-2-receptor blockers, and proton pump inhibitors.
The Role of Diet in Acid Reflux: 8 Worst Foods for Acid Reflux
Diet has a significant impact on the development and management of acid reflux. Some foods and beverages are known to relax the lower esophageal sphincter (LES), making it easier for stomach acid to backflow into the esophagus and trigger acid reflux. Certain foods can also increase the production of stomach acid, exacerbating acid reflux symptoms.
1. Onions and Garlic
Onions and garlic are both known to cause issues for some individuals with acid reflux. These foods have the potential to relax the LES, similar to chocolate, increasing the risk of acid reflux. They are also high in fermentable fiber, which could potentially lead to bloating and increased pressure in the stomach.
2. Acidic Foods and Beverages
Acidic foods and drinks, such as citrus fruits, tomatoes, coffee, and carbonated beverages, can exacerbate acid reflux symptoms by increasing the acidity of the stomach. This heightened acidity can irritate the esophagus, particularly if the LES is weakened or relaxed, allowing acid to reflux into the esophagus.
3. Spicy Foods
Although spicy foods don’t necessarily affect the LES or increase stomach acid, they can cause irritation to the esophagus. This irritation can mimic or worsen heartburn, which is a common symptom of acid reflux. People with GERD are often advised to limit or avoid spicy foods to reduce their symptoms.
Chocolate contains a compound called methylxanthine, which has been shown to relax the LES. A relaxed LES is more likely to allow stomach acid to reflux into the esophagus, leading to the symptoms of heartburn and acid reflux.
5. High-Fat Foods
Foods that are high in fat can slow down digestion because they require more stomach acid to break down. As a result, they can increase the length of time food remains in your stomach, increasing gastric pressure.
This extra pressure on the lower esophageal sphincter (LES) can lead to acid reflux as it makes it easier for stomach acid to escape into the esophagus. Examples of high-fat foods include fast foods, fried foods, fatty cuts of meats, butter, full-fat dairy products, and rich desserts like pastries.
Alcohol can exacerbate acid reflux in multiple ways. It relaxes the LES, increases the production of stomach acid, and slows the rate of digestion. Each of these factors can contribute to an increased risk of experiencing acid reflux after consuming alcohol.
Similar to chocolate, caffeine can relax the LES, making it easier for stomach acid to escape into the esophagus. This includes caffeinated beverages like coffee, tea, and some sodas.
While mint is often associated with soothing the stomach, it can have a contrary effect for those with acid reflux. Both peppermint and spearmint have been shown to relax the LES. This relaxation can make it easier for stomach acid to reflux into the esophagus, causing symptoms of heartburn and acid reflux.
Onions and Acid Reflux
Onions are an integral part of many cuisines worldwide due to their unique flavor and versatility in cooking. However, for people dealing with acid reflux, onions can prove to be a troublesome food.
1. Impact on LES
Onions, particularly raw onions, contain compounds that can relax the lower esophageal sphincter (LES), making it easier for stomach acid to reflux into the esophagus. Relaxation of the LES is one of the primary causes of acid reflux, and any food that facilitates this process can potentially trigger symptoms.
2. High Fermentable Fiber Content
Onions contain a type of fiber known as fructans. Fructans fall into the category of FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols), a group of compounds that can lead to digestive issues in some individuals. These compounds are fermented by gut bacteria, leading to increased gas production. This extra gas can increase pressure within the stomach, potentially pushing acid up into the esophagus.
3. Individual Tolerances
While onions are a common trigger food for acid reflux, it’s important to remember that everyone’s body reacts differently to different types of foods. Some people might be able to consume onions without experiencing any acid reflux symptoms, while others might find that even a small amount can cause significant discomfort.
4. Cooking and Acid Reflux
Cooking onions can break down some of the compounds that contribute to acid reflux, potentially making them less likely to cause symptoms. However, even cooked onions can lead to discomfort in some individuals.
As with many aspects of managing acid reflux, understanding the impact of onions on your body might involve a bit of trial and error. Monitoring your symptoms and making dietary adjustments as needed is key to finding what works best for you.
Are Onions Bad for Acid Reflux: What Type of Onion Can You Eat?
Are Raw Onions Bad for Acid Reflux?
Raw onions have a particularly strong, pungent flavor. This intensity comes from a higher concentration of the compounds that can relax the lower esophageal sphincter, potentially leading to acid reflux. Because of this, raw onions are often more likely to cause acid reflux than cooked onions.
For people with GERD, it may be best to avoid raw onions entirely. Instead, consider using herbs and spices that can provide flavor without the same risk of triggering acid reflux.
Are Cooked Onions Bad for Acid Reflux?
Cooked onions often have a milder flavor than their raw counterparts. The cooking process can break down some of the compounds in onions that may contribute to acid reflux. However, the high fermentable fiber content can still potentially lead to increased gas production, which might exacerbate acid reflux symptoms.
While cooking might make onions less likely to trigger acid reflux, individual sensitivities vary. Some people might still experience discomfort after consuming cooked onions.
Are Green Onions Bad for Acid Reflux?
Green onions, also known as spring onions or scallions, are typically milder than other onion types. This mildness extends to the green parts of these onions, which are generally less likely to trigger acid reflux.
The white bulb of green onions, however, has a stronger flavor and may still provoke acid reflux in some individuals. Therefore, people with acid reflux who still want to enjoy the flavor of onions might opt to use the green parts of green onions in their cooking.
However, remember that everyone’s body is different, and what works for one person might not work for another. More research is needed in this area to definitively determine whether green onions are a safe alternative for people with acid reflux.
Are Red Onions Bad for Acid Reflux?
Despite their vibrant color and robust flavor, red onions can be just as likely to trigger acid reflux as their white or yellow counterparts. Red onions contain the same high fermentable fiber content that can lead to increased gas production and exacerbate acid reflux symptoms.
Even though their sweet, mild flavor when cooked might seem less potent, individuals with acid reflux might still experience discomfort after consuming red onions.
Managing Acid Reflux through Diet
While medications can help manage acid reflux, dietary changes often play a crucial role in controlling this condition.
1. Identifying Trigger Foods
The first step in managing acid reflux through diet is to identify and avoid foods that trigger your symptoms. Common triggers include high-fat foods, acidic foods, spicy foods, chocolate, onions, garlic, alcohol, caffeine, and mint. However, triggers can vary significantly from person to person, so it’s essential to track your food intake and symptoms to identify your personal triggers.
2. Eating Smaller, Frequent Meals
Large meals can cause your stomach to distend, increasing pressure on the lower esophageal sphincter (LES) and making it easier for stomach acid to reflux into the esophagus. Instead, try eating smaller, more frequent meals throughout the day.
3. Avoiding Late-Night Eating
Eating within 2-3 hours before going to bed can increase the risk of acid reflux. When you lie down, it’s easier for stomach acid to escape into your esophagus. Try to make sure you finish eating at least a few hours before bedtime.
4. Including GERD-Friendly Foods
Certain foods are less likely to trigger acid reflux and can be included in your diet. These include lean proteins, non-acidic fruits and vegetables, whole grains, and healthy fats. Again, individual reactions can vary, so it’s important to monitor your body’s responses to different foods.
5. Drinking Plenty of Water
Staying well-hydrated is also crucial for managing acid reflux. Water can help neutralize stomach acid and keep your digestive system functioning properly.
6. Maintaining a Healthy Weight
Excess weight, particularly around your midsection, can put additional pressure on your stomach and LES, increasing the risk of acid reflux. Eating a balanced diet and maintaining a healthy weight can significantly reduce acid reflux symptoms.
Remember, everyone’s body is different, and what works for one person might not work for another. It may take some time and experimentation to find what dietary changes work best for you. Always consult with a healthcare provider or a dietitian when making significant changes to your diet to manage a health condition.
The 7 Best Foods for Acid Reflux
There are several foods and beverages known for their potential to reduce acid reflux symptoms. While individual tolerance can vary, the following are generally considered beneficial for most people with acid reflux:
1. Lean Proteins
Foods like skinless chicken, turkey, fish, and egg whites are high in protein and low in fat, making them excellent choices for those dealing with acid reflux. Protein is an essential nutrient that aids in tissue repair and growth, while their low-fat content minimizes the risk of triggering reflux.
2. Non-Acidic Fruits and Vegetables
Non-acidic fruits and vegetables such as melons, bananas, broccoli, peas, green beans, and potatoes can be a safe choice as they are less likely to trigger acid reflux.
3. Whole Grains
Foods such as oatmeal, brown rice, quinoa, and whole grain bread or pasta are high in dietary fiber. Fiber not only promotes digestive health, but it can also absorb excess stomach acid, reducing the risk of reflux.
4. Healthy Fats
Sources of healthy fats like avocados, walnuts, flaxseeds, and olive oil are less likely to trigger acid reflux compared to saturated fats. These foods also contribute to overall health by providing essential fatty acids and reducing inflammation.
For centuries, ginger has been used for its potential gastrointestinal benefits. It’s known to soothe the stomach and could potentially reduce acid reflux symptoms.
6. Non-Citrus Beverages
Non-citrus beverages like chamomile tea, almond milk, and coconut water can be less irritating to the stomach and esophagus than acidic drinks like coffee and citrus juices.
7. Probiotic Foods
Foods like yogurt and kombucha, or other fermented foods, contain probiotics which improve digestion and may reduce instances of acid reflux.
In conclusion, while onions are frequently listed as a potential trigger for acid reflux, individual reactions can vary. It is essential to monitor your dietary habits, avoid foods that cause discomfort, and seek medical advice for persistent acid reflux symptoms.
Remember, managing acid reflux often goes beyond the question, “Are onions bad for acid reflux?” and encompasses a comprehensive approach involving dietary changes and lifestyle modifications.
