Is Salmon Low FODMAP?
Salmon is LOW FODMAP. You can enjoy plain salmon freely on a low FODMAP diet without worrying about portion sizes. According to Monash University, plain salmon (whether fresh, frozen, or canned in brine) remains low FODMAP even at servings up to 500 grams, making it an excellent protein choice for managing IBS symptoms.
Safe Serving Size
| Serving | FODMAP Level |
|---|---|
| 100g (1 can or small fillet) | Low |
| 200g (1 large fillet) | Low |
| 500g+ | Low |
Salmon is naturally FODMAP-free because it contains no carbohydrates. A standard serving of 100g provides approximately 20.7g of high-quality protein, along with beneficial omega-3 fatty acids, all with zero FODMAP content. Both fresh and canned salmon are equally safe on a low FODMAP diet.
Why Doesn’t Salmon Contain FODMAPs?
Salmon is pure protein and fat with no carbohydrates. FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) are all types of carbohydrates that can trigger digestive symptoms in sensitive individuals.
Since plain salmon contains no carbohydrates, it naturally doesn’t contain any of the problematic sugars:
- No Fructans - Found in wheat, garlic, and onion
- No GOS (Galacto-oligosaccharides) - Found in legumes
- No Lactose - Found in dairy products
- No Polyols - Found in some fruits and sweeteners
- No Excess Fructose - Found in honey and certain fruits
This makes salmon not only safe for IBS but also incredibly nutritious, providing anti-inflammatory omega-3 fatty acids that may actually help reduce gut inflammation.
