Salmon is one of the most popular and nutritious types of fish. Rich in protein, omega-3 fatty acids, vitamins, and minerals, salmon offers many health benefits. However, some people wonder if certain blood types should avoid eating salmon. This article examines if people with different blood types can eat salmon.
Overview of Blood Types
There are four main blood types:
- Type A
- Type B
- Type AB
- Type O
Blood types are determined by the types of antigens on the blood cells. Antigens are proteins that can trigger an immune response if the body encounters unfamiliar ones. The four blood types have different antigens:
- Type A has A antigens
- Type B has B antigens
- Type AB has both A and B antigens
- Type O has neither A nor B antigens
The distribution of the main blood groups varies worldwide. In the United States, the most common is type O at 44% of the population. Type A is second most common at 42%, followed by type B at 10% and type AB at 4%.
Blood Type Diet Theory
The blood type diet, also called the blood group diet, suggests that your blood type determines how your body handles different foods. The diet claims that lectins—proteins found in certain foods—bind to antigens in the blood and cause agglutination, or clumping together of red blood cells.
This theory suggests that people with different blood types should follow specific diets to avoid lectins that are incompatible with their blood type. For example, those with type O blood are advised to eat a high protein diet and avoid wheat, corn, and dairy products.
However, most experts agree there is insufficient evidence to support the blood type diet theory. No large-scale studies have demonstrated that blood types directly influence diet responses or health outcomes.
Can Type O Eat Salmon?
The blood type diet recommends that people with type O blood avoid most seafood, including salmon. This is because salmon contains lectins that can agglutinate type O blood, according to the diet’s claims.
However, there is no scientific evidence that eating salmon is harmful or unhealthy for people with type O blood. In fact, salmon provides excellent nutrition for all blood types with its high-quality protein, omega-3s, B vitamins, and minerals like potassium and selenium.
While a small percentage of the population may have food sensitivities to salmon, these reactions are not specifically tied to blood type O. People with type O blood can safely enjoy salmon as part of a healthy, balanced diet, just like other blood types.
Can Type A Eat Salmon?
The blood type diet classifies salmon as a “neutral” food for people with type A blood. This means it neither helps or harms people with type A blood, according to the diet’s claims.
Again, there is no clinical evidence that type A individuals need to restrict salmon or seafood in their diets. Salmon is loaded with nutrients that provide health benefits to all blood types:
- High-quality protein for energy, muscle repair, and immunity
- Heart-healthy omega-3 fatty acids EPA and DHA
- B vitamins niacin, B12, and B6
- Potassium to regulate fluid balance
- Selenium, an important antioxidant
While a rare seafood allergy may exist, salmon poses no specific issues for people with type A blood. Salmon can be safely enjoyed as part of a nutritious diet for blood type A.
Can Type B Eat Salmon?
The blood type diet recommends that people with type B blood avoid all seafood, including salmon. This is because of lectins contained in seafood that can supposedly agglutinate type B blood cells.
However, there is no credible evidence that eating salmon or other seafood is bad for people with type B blood. In fact, salmon provides great nutritional benefits for type B individuals:
- High-quality, lean protein to support energy and muscle tissue
- Abundant anti-inflammatory omega-3s EPA and DHA
- Niacin, B12, and other B vitamins for red blood cell formation
- Selenium and potassium to support immune function
People with type B blood can safely include salmon in their diet. There are no lectins or other compounds in salmon that interact negatively with type B blood.
Can Type AB Eat Salmon?
For people with type AB blood, the blood type diet recommends avoiding all seafood, including salmon. The diet claims this is because of lectins in seafood that clash with type AB blood.
However, there is no scientific evidence that salmon lectins interact harmfully with type AB blood. Furthermore, salmon provides excellent nutrition for people with type AB blood:
- Complete protein containing all essential amino acids
- Anti-inflammatory omega-3 fatty acids EPA and DHA
- B vitamins for generating red blood cells and cellular energy
- Minerals like selenium and potassium to support the immune system
People with type AB blood do not need to restrict salmon or other seafoods. Salmon can be safely enjoyed as part of a nutritious, balanced diet for type AB individuals.
Nutritional Profile of Salmon

As shown, salmon is high in protein, omega-3s, B vitamins, selenium, niacin, and potassium. These nutrients provide health benefits for all blood types.
Health Benefits of Salmon for All Blood Types
Here is an overview of the top health benefits salmon provides:
- Reduces inflammation – The omega-3s in salmon have potent anti-inflammatory properties to lower chronic inflammation, a risk factor for many diseases.
- Boosts heart health – Eating salmon raises HDL (good) cholesterol and lowers blood pressure and triglycerides, reducing heart disease risk.
- Supports brain function – The omega-3 DHA in salmon enhances cognitive function and may help prevent dementia.
- Aids vision – Salmon provides antioxidants like astaxanthin that help prevent age-related macular degeneration and vision loss.
- Promotes skin and hair health – The omega-3s in salmon keep skin radiant by retaining moisture and reduce dryness.
- Enhances weight control – The protein in salmon increases satiety, while the omega-3s help boost fat burning.
These benefits apply equally to all blood types when eating salmon.
Risks of Eating Too Much Salmon
While salmon is very healthy, there are some potential downsides to eating too much:
- May contain contaminants like mercury, dioxins, and PCBs from the environment, especially in wild salmon.
- Farmed salmon may have higher antibiotic use and lower omega-3 levels if not raised properly.
- Some people are allergic to salmon and other seafood.
- Beta-alanine in salmon may cause flushing reactions in those taking beta-blockers.
To avoid issues, limit salmon intake to 2-3 servings per week. Choose wild-caught Alaskan salmon when possible, and cook properly to reduce contaminant exposure. People with seafood allergies should take precautions.
How to Select and Prepare Salmon
Follow these tips to choose fresh salmon and cook it optimally:
- Look for wild-caught Alaskan salmon like sockeye, coho, or king for highest omega-3s.
- Choose salmon steaks or fillets with firm, shiny, moist flesh without discoloration.
- Store fresh salmon for up to 2 days in the coldest part of refrigerator.
- Freeze for up to 3 months to retain freshness.
- Thaw frozen salmon in the refrigerator, not at room temperature.
- Cook to an internal temperature of at least 145°F, until opaque and flaky.
- Broil, bake, or grill salmon to reduce any contaminants present.
Proper selection, storage, and cooking helps maximize the health benefits of salmon.
Sample Salmon Recipes
Here are some delicious ways to enjoy salmon:
Lemon Garlic Baked Salmon

The Bottom Line
Despite blood type diet claims, there is no credible evidence that people with type O, A, B, or AB blood need to avoid salmon due to lectins or other compounds. Salmon provides great nutrition through its complete protein, anti-inflammatory omega-3s, and abundance of B vitamins and minerals.
People with all blood types can safely eat 2-3 servings of salmon per week as part of a healthy diet, focusing on wild-caught Alaskan salmon. Properly cooking salmon reduces any potential contaminants. In moderation, salmon offers delicious taste and stellar nutrition for all blood types.
