Salmon is a delicious and nutritious fish that is enjoyed by many However, some people experience stomach upset after eating salmon There are a few potential reasons why salmon may cause gastrointestinal discomfort.
Salmon Allergy
One of the most common causes of stomach upset after consuming salmon is a food allergy. Salmon allergies affect approximately 0.4% of the population in the United States.
An allergy occurs when the immune system mistakenly identifies proteins in salmon as harmful and launches an immune response. This provokes various allergic reaction symptoms, including stomach pain, cramps, nausea and vomiting.
Salmon contains parvalbumin a protein that commonly triggers fish allergy. People with existing allergies, particularly to seafood, are at higher risk of developing a salmon allergy. Adults account for most salmon allergy cases with over 60% experiencing their first reaction in adulthood.
If you suspect a salmon allergy it’s crucial to see an allergist. They can perform skin or blood tests to diagnose a fish allergy. Strict avoidance of salmon and other fish is key to preventing an allergic reaction. Carrying emergency epinephrine is vital for those with a severe salmon allergy.
Foodborne Illness
Another potential cause of salmon-induced stomach upset is food poisoning from bacteria, viruses or parasites. Salmonella is one of the most common culprits.
Symptoms occur within 12 to 72 hours after eating contaminated salmon. They include stomach pain, diarrhea, nausea, vomiting, headache and fever.
Pregnant women, young children, older adults and those with weakened immune systems have a higher risk of developing foodborne illness. Proper handling, cooking and storage of salmon is crucial to destroy any dangerous microbes.
High Fat Content
The high concentration of omega-3 fats in salmon delivers substantial health perks. But for some individuals, the fatty richness can irritate the digestive tract. Fat digestion begins in the mouth, stomach and small intestine.
If you have problems with your gallbladder, which releases bile to help break down fats, the high-fat salmon may provoke stomach discomfort. People with irritable bowel syndrome (IBS) or other GI issues may also struggle.
Limiting portion size, choosing leaner cuts of salmon or taking a fish oil supplement instead can help minimize adverse effects. See a doctor to identify and manage any underlying digestive problems.
Environmental Contaminants
Farmed and wild salmon can pick up environmental pollutants, like mercury, PCBs and dioxins. The contaminants accumulate in their tissues and organs over their lifespan. High exposure to contaminants through frequent salmon consumption may cause stomach upset in sensitive people.
Choosing sustainably sourced wild salmon can help decrease contaminant levels. Opting for young, small salmon may also lower exposure. Grilling, broiling or baking instead of frying also reduces certain pollutants compared to other cooking methods.
Histamine Intolerance
Salmon naturally contains high levels of histamine, which is produced as fish decomposes. Some individuals lack adequate levels of diamine oxidase, the enzyme needed to break down histamine.
The accumulation of histamine can trigger stomach problems, headaches, hives, flushing and other symptoms. People with histamine intolerance need to strictly limit their intake of histamine-rich foods like salmon. Antihistamines may also help provide relief of symptoms.
Tips to Prevent Salmon-Induced Stomach Upset
-
Purchase wild-caught salmon from reputable sustainable sources
-
Ensure proper storage at 40°F or below
-
Cook salmon thoroughly to an internal temperature of 145°F
-
Consume leftover salmon within 3 to 4 days and reheat to 165°F
-
Reduce portion size if sensitive to fat
-
Take a fish oil supplement as an alternative omega-3 source
-
Avoid salmon if you have a seafood allergy or histamine intolerance
-
See a doctor to evaluate any chronic GI issues
While salmon can occasionally cause stomach troubles, it provides ample nutrients and health benefits for most people. Follow basic food safety practices when handling raw salmon. Listen to your body, and avoid salmon if it frequently upsets your stomach or causes an allergic reaction. Speak to your healthcare provider if salmon-induced stomach pain is ongoing to identify any underlying issues requiring treatment.
Is Salmon the Most Common Fish Allergy?
Salmon, tuna, and cod are considered to be the most common fish allergens. A study in Texas found that 23.8% of fish allergy patients reported a salmon allergy.
Salmon Allergy vs. Salmon Sensitivity
Whilst approximately 0.4% of Americans suffer from fish allergy, sensitivities to salmon are much more common.
Understanding the difference between an allergy and an intolerance is key for managing symptoms and adapting your diet appropriately. While both conditions can impact quality of life, they involve different bodily responses, and a salmon sensitivity is typically less serious.
Here are some of the key differences to remember:
- A salmon allergy elicits an IgE antibody immune response whereas a salmon sensitivity triggers an IgG antibody response.
- Symptoms of an allergic reaction can begin immediately, or shortly after, contact with a trigger allergen. On the other hand, symptoms of salmon sensitivity can take several days to appear.
- The typical profile of symptoms differs. Whilst a salmon allergy is linked to swelling, itching and sneezing, a sensitivity is more likely to trigger symptoms such as:
- Diarrhea
- Bloating
- Skin conditions e.g. eczema or psoriasis
- Headaches
- Fatigue
- Low energy or mood
If youâre experiencing any of the symptoms on the list above, we recommend taking a Premium Food Sensitivity Test to see whether salmon is triggering an IgG reaction in your body. The good news is, if youâre experiencing a sensitivity rather than an allergy, you may be able to reintroduce salmon into your diet after an elimination diet and under the advice of a nutrition professional.
