Is Fish Acidic? (Which one the least?)

Fish is one of the healthiest foods on the planet. It’s loaded with nutrients, minerals, and vitamins that help you stay healthy.

There are also many varieties of fish so everyone can find something they like.

However, if you’re following a special dietary plan — for example, a diet low in acidic foods — it’s important to be aware of the acid content of various fish types and whether it’s safe to consume it on such a diet. So, is fish acidic?

Fish is mildly acidic, depending on the kind and the way it’s prepared. On top of that, fish is loaded with healthy fats and lots of nutrients, so it can help you stay healthy and ward off many diseases. It’s also effortless to add to your diet, and the many varieties of fish will satisfy everyone’s palate.

What is the pH level of fish?

Fish is only mildly acidic, having a pH ranging between 5.3-6.5. Salmon leans towards the higher end of this scale, while white fish, such as cod, tend to be slightly lower.

Nevertheless, all fish is only mildly acidic, making them a wonderful addition to a low-acid diet.

Plus, all types of fish come with many health benefits and essential omega-3 fatty acids, which can also help keep your stomach flora healthy, thus preventing the symptoms of GERD and acid reflux.

Fish is one of the most nutritious foods out there. It’s packed with essential vitamins and minerals that help you stay healthy, so it’s a good idea to consume fish once or twice a week.

Depending on the type of fish, it contains a good amount of nutrients per caloric content.

For example, one fillet of cod contains about 181 calories and 41g of protein. This very impressive amount of protein helps you feel full after a meal, preventing overeating and weight gain.

Healthy fats

On the other hand, fattier fish, such as salmon, contain slightly more calories but lots of healthy fats that improve your health.

What’s more, fish is also one of the best foods for heart health. In fact, people who consume fish regularly have a decreased risk of heart attack, and their blood pressure is also lower.

This is because the healthy fats in fish help protect your heart and lower your bad cholesterol levels. In addition, the same fats and minerals also help prevent strokes and death from other heart conditions, which unfortunately is one of the leading causes of death worldwide.

Hence, adding fish to your diet can help you live a long and healthy life.

Furthermore, all types of fish are rich in omega-3 fatty acids. These compounds are crucial for development and growth. As a result, children and teenagers should consume fish to reap those benefits and ensure proper brain function. 

These fatty acids are also responsible for protecting your eyesight and retina from age-related conditions as well as damage caused by free radicals. Therefore, it’s important to include omega-3 fatty acids in your diet as your body can’t produce them on its own.

On the other hand, it’s important to remember that certain types of fish are high in mercury, which has been linked to brain developmental problems.

As a result, pregnant women should only consume fish low in mercury, such as salmon, sardines, and trout, and avoid all types of seafood as they’re very high in mercury.

The same goes for young children who are developing and growing, but low-mercury fish should be an integral part of most diets.

Fish is mildly acidic, so it’s safe to consume by most people who suffer from acid reflux or GERD. However, it depends on how sensitive you are to acidic foods, so always add new foods to your diets slowly and check how you feel.

Furthermore, if you’re worried about consuming fish because of their acidity, start with the least acidic fish, such as salmon.

That way, you can check how you react and whether it aggregates your acid reflux or GERD. Then, you can slowly add more fish types.

What type of fish is the least acidic?

While most fish have around the same pH level, some fish are slightly more acidic than others. For example, bluefish, cuttlefish, and salmon have a higher pH level than cod and mackerel.

Hence, if you’re especially sensitive to acidic foods, it might be best to opt for these fish that are lower in acid.

Nevertheless, if you can consume slightly more acidic foods, it’s best to alternate between various fish types to get the most out of the health benefits.

Is canned fish bad for acid reflux?

Canned fish has around the same pH level as the fresh version. However, it also depends on what it’s packed with. For example, if you’re buying canned mackerel in tomato sauce, the pH level is going to be way lower as tomatoes are acidic.

As a result, the safest choices are fish packed with water or oil, as their acidity remains relatively unchanged. For example, canned tuna has a pH level of 5.9-6.0, so even though it’s slightly lower, it’s still safe to consume when dealing with GERD and acid reflux.

Another important thing to remember is that canned foods often have added sodium. While necessary and important, this mineral can raise your blood pressure, leading to many health conditions.

As a result, it’s important to limit your intake of salt. To do that, make sure to check the food labels before buying canned goods.

Fish is a food loaded with nutrients, and it’s only mildly acidic. As a result, it can be safely included on a low-acid diet that’s aimed at controlling the symptoms of acid reflux and GERD.

Furthermore, all types of fish contain omega-3 fatty acids that your body can’t produce on its own, so it’s important to include foods high in these compounds.

As always, though, make sure that you consume the types of fish that don’t worsen your symptoms as fish is still slightly acidic.
