Is Salmon Low FODMAP? The Answer May Surprise You!

If you’re looking for a low FODMAP protein source that is easy to prepare and delicious, salmon may be the answer. But is salmon actually low FODMAP? The answer is not as straightforward as you might think.

What is the low FODMAP diet?

The low FODMAP diet is a dietary approach that has been shown to be effective in managing symptoms of irritable bowel syndrome (IBS). FODMAPs are fermentable carbohydrates that can be poorly absorbed in the small intestine, leading to symptoms such as bloating, gas, and abdominal pain for people with IBS. The low FODMAP diet involves avoiding foods that are high in FODMAPs for a period of time, and then gradually reintroducing them to see which ones can be tolerated without triggering symptoms.

What are FODMAPs?

FODMAPs are a group of carbohydrates that are not well-absorbed in the small intestine, which can lead to symptoms such as bloating, gas, and abdominal pain. The term FODMAP is an acronym for:

  • Fermentable
  • Oligosaccharides
  • Disaccharides
  • Monosaccharides
  • And
  • Polyols

Examples of high-FODMAP foods include:

  • Wheat
  • Rye
  • Barley
  • Garlic
  • Onion
  • Apples
  • Pears
  • Mangoes
  • Watermelon
  • Mushrooms
  • And more

Is salmon low FODMAP?

The short answer is yes, salmon is low FODMAP. However, there are some important caveats to keep in mind.

Fresh vs. canned salmon

While fresh salmon is low FODMAP, canned salmon can be higher in FODMAPs due to added ingredients like onion or garlic powder. If you’re on a low FODMAP diet, be sure to check the ingredients list on any canned salmon you buy.

Serving size

Like any food, the FODMAP content of salmon can vary depending on the serving size. According to Monash University, a serving size of 1/2 cup canned salmon is low FODMAP, while a serving size of 3/4 cup canned salmon is high FODMAP due to onion powder in the ingredients.

Preparation method

The way you prepare salmon can also affect its FODMAP content. For example, cooking salmon with garlic or onion could make it higher in FODMAPs. If you’re on a low FODMAP diet, look for recipes that use low FODMAP ingredients to prepare salmon.

Health benefits of salmon

Whether you’re following a low FODMAP diet or not, salmon is a nutritious choice that can provide a range of health benefits. Here are just a few:

  • High in omega-3 fatty acids, which can improve heart health, reduce inflammation, and promote brain health.
  • A good source of protein, which is important for building and repairing tissues.
  • Rich in vitamins and minerals like vitamin D, vitamin B12, and selenium.
