Salmon is a type of fatty fish that is not only delicious but also packed with several nutrients that are beneficial for your health. The American Heart Association (AHA) recommends consuming fish, such as salmon, at least twice a week due to its high protein content and heart-healthy omega-3 fatty acids. A standard serving size of fish is three ounces cooked or approximately 3/4 cups of flaked fish.
Aside from being a great source of protein, salmon also contains other essential nutrients such as copper, potassium, selenium, vitamin B12, and vitamin D, which are important for maintaining overall body functions.
Benefits of Salmon Protein
Aids in Muscle Recovery
Salmon is known for its high protein content, with approximately 16 grams of protein in a three-ounce serving. Protein plays a crucial role in cell production, repair, and muscle health. Consuming enough protein is essential to prevent muscle loss.
Research published in 2020 found that the protein content in salmon can help stimulate muscle protein synthesis after exercise. The study involved 10 active adults who performed resistance exercise and then consumed salmon or crystalline amino acids and fish oil with 20 grams of protein.
Sustainable Choice
Choosing salmon as a source of protein is not only beneficial for your health but also for the environment. If sourced from sustainable fisheries, salmon can be an environmentally conscious choice.
Alaska Salmon, for example, is both wild-caught and sustainable, making it good for both the environment and our health. Compared to other animal sources of protein, farmed salmon has a smaller carbon footprint as it requires less land and resources.
May Protect Against Chronic Illnesses
Wild-caught salmon contains a carotenoid called astaxanthin, which is known for its antioxidant, anti-inflammatory, and anticancer properties. Antioxidants play a crucial role in protecting against cell damage that can lead to chronic illnesses such as Alzheimer's disease, certain cancers, diabetes, eye diseases, heart diseases, and Parkinson's disease.
Supports Heart Health
The AHA recommends incorporating omega-3 fatty acids into a heart-healthy diet, and salmon is an excellent source of these essential fatty acids. Research has shown that replacing saturated fats from animal sources with omega-3 fatty acids found in fish can help reduce total blood cholesterol.
Omega-3s found in salmon have been found to:
- Decrease the buildup of fatty substances in the arteries (atherosclerosis)
- Improve the flexibility of arteries and increase blood flow
- Increase HDL ( good ) cholesterol
- Reduce inflammation
- Protect against blockages in the coronary artery
- Lower the risk of irregular heart rhythm (arrhythmia)

In addition to protein, salmon is also a good source of other essential vitamins and minerals:
- Iron: Important for oxygen transportation and muscle metabolism.
- Selenium: Supports antioxidant activity and prevents cell damage.
- Vitamin A: Essential for teeth, skin, eyesight, pregnancy, and breastfeeding.
- Vitamin B3: Aids in digestion and supports nerve and skin functions.
- Vitamin B12: Prevents anemia and supports nerve function.
- Vitamin D: Helps absorb calcium and supports nerve, muscle, and immune systems.
- Zinc: Supports immune function, cell growth, and wound healing.
Risks of Consuming Salmon
Salmon is generally safe to consume, but individuals with fish allergies should exercise caution. Some people may be allergic to specific types of fish, so it's important to be aware of any allergic reactions that may occur after consuming salmon.
Symptoms of fish allergies may include anaphylaxis, asthma, gastrointestinal symptoms (nausea, vomiting, diarrhea), headache, hives, sneezing, stuffy or runny nose. It is worth noting that fish allergies can develop during adulthood, with nearly 40% of people developing symptoms later in life.
Another potential risk associated with consuming fish is the presence of toxins, such as mercury. However, salmon has one of the lowest levels of mercury among fish varieties. The benefits of salmon outweigh the potential risk of mercury poisoning.
Tips for Consuming Salmon
When purchasing salmon, you have various options, including fresh, frozen, smoked, and canned varieties. Here are some tips to keep in mind:
- Choose fresh salmon with a mild fresh smell, clear shiny eyes, and firm flesh that springs back when pressed.
- Frozen salmon should also have a fresh smell and should not develop any fishy or sour odors after cooking.
- Prevent cross-contamination by washing hands, utensils, and surfaces after handling raw fish.
- Salmon can be consumed cooked or raw, but cooking the fish reduces the risk of food poisoning. If consuming raw salmon, ensure that it was previously frozen.
To summarize, smoked salmon is indeed a good source of protein, along with other essential nutrients. It offers various health benefits, including muscle recovery, heart health support, protection against chronic illnesses, and sustainability. However, individuals with fish allergies should be cautious, and it's important to handle and prepare salmon properly to minimize the risk of foodborne illnesses.
