Is Tuna Good for Acid Reflux?


If you have acid reflux, you may be wondering if you can eat tuna without aggravating your symptoms.

The good news is that in most cases, tuna is safe for people with acid reflux. However, there are a few things to consider before you indulge in this tasty fish.

Below we will break down all the important information you need to know before you eat tuna.

What is Tuna and How Does It Affect Acid Reflux?

Tuna is a saltwater fish that is commonly eaten around the world. It is a great source of protein, omega-3 fatty acids, vitamin D, and other nutrients that are beneficial for your health.

When it comes to acid reflux, tuna is slightly acidic, with a pH around 5-6. This means that it is safe for most people with acid reflux to eat tuna without experiencing any symptoms.

However, there are some factors that can affect the acidity of tuna. For example, if you cook tuna with acidic marinades or sauces, it can become more acidic and potentially trigger acid reflux symptoms.

Similarly, canned tuna that is packed with preservatives can be more acidic than fresh or frozen tuna. To minimize the acidity of tuna, try grilling, baking, or steaming it with mild herbs and spices.

When choosing tuna for acid reflux, it’s also important to consider the type of tuna and how it is packed. Fresh or frozen tuna is generally a better choice than canned tuna, as it is less likely to be packed with preservatives.

If you do opt for canned tuna, choose water-packed tuna over oil-packed tuna to reduce your fat intake and acidity. Finally, look for low-sodium tuna options to minimize your salt intake.

What are the Pros and Cons of Eating Tuna for Acid Reflux?

As with any food, there are pros and cons to eating tuna if you have acid reflux. Here are some of the main points to consider:


  • Tuna is high in protein and omega-3 fatty acids, which can help reduce inflammation and heal the esophagus.
  • Tuna is slightly acidic but not acidic enough to be of concern for most people with acid reflux.
  • Tuna is rich in vitamin D, which can help regulate calcium absorption and prevent bone loss.


  • Canned tuna is often packed in oil or preservatives, which can increase fat intake and also often increases acidity, ideally choice canned tuna with no preservatives or added oils.
  • While unlikely, some tuna may contain mercury or other contaminants, which can pose health risks if consumed too frequently.
