Whether you eat them raw in sushi or as smoked salmon, these fish are packed with omega-3 fatty acids, which have earned their reputation as a highly health-supportive food. The health benefits of salmon include sound cardiovascular health, reduced risk of cancer, improved cognition, bone and joint protection, healthy skin, better vision, and efficient metabolism. Salmon is also known to be a brain food for children and a calming food for those with ADHD.

What is Salmon?

Salmon is a species of fish which is found both in fresh water (rivers) and saline water (seas), depending on the stage of its development.

They have a peculiar life cycle. The fish lay their eggs near the mouth of rivers, where the eggs hatch, develop into fries and start their journey toward the sea. They grow into adult salmon in the sea, then go back to the rivers to reproduce, where most of them die after laying their eggs.

The varieties of this fish are usually identified based on the ocean where they are located. The scientific name of the salmon family is Oncorhynchus in the Pacific, while they belong to the Salmogenus in the Atlantic. There is only one type of Atlantic salmon, and five kinds of Pacific salmon namely, chinook (or king), sockeye (or red), coho (or silver), pink, and chum. Another popular variety is wild Alaskan salmon.

The flesh of the salmon is usually pink but can range between shades of red to orange.

Nutritional Value of Salmon

This well-known and popular fish is a very good source of easily digestible proteins (amino acids), and fatty acids like Omega-3 in the form of triglyceride, as well as vitamins like vitamin A, vitamin D and some members of the B vitamin family like choline, pantothenic acid, and biotin. It also contains minerals like selenium, zinc, phosphorus, calcium, and iron.


Health Benefits of Salmon

The health benefits of eating salmon include the following:

Great Source of Lean Protein

Proteins, or accumulations of amino acids, are essential components of our cells, tissues, enzymes, hormones and every other body part. The proteins from salmon and most other fishes are easily digestible and easily absorbed into the body. They don’t have any adverse side effects, nor do they contain carcinogenic compounds like some other meats do.

Promotes General Wellness

Salmon is also a source of “good” cholesterol (omega-3 fatty acids) which also plays a vital role in keeping you healthy. Salmon is also rich in some essential minerals like iron, calcium, selenium, and phosphorus, as well as vitamins like A, B, and D. Selenium, which is necessary for the metabolism of tissues, hair, and nails, is best obtained from animal proteins. Among animals, salmon is one of the best sources for this trace element.

Bone and Joint Health

Salmon has the powerful combination of polyunsaturated fatty acids along with vitamin D, both of which are linked to reduced risk of osteoarthritis. Researchers at Ohio State University found that women who consumed a diet rich in omega-3 fatty acids had lesser hip fractures. This is because omega-3s are a natural anti-inflammatory food, and they reduce the incidence of bone resorption due to inflammation.

Protects the Brain and Nerves

The omega-3 fatty acids increase the efficiency of brain functions, improves memory and keep it active during long working hours. Along with the amino acids, vitamin A, vitamin D, choline, and selenium, these fatty acids protect the nervous system from damage related to aging, acts as an antidepressant, relaxes the brain, and helps in treating Alzheimer’s and Parkinson’s disease.

Cardiovascular Health

While the omega-3 fatty acids help reduce cholesterol, maintain flexibility of arteries and veins and strengthen cardiac muscles, the essential amino acids repair damages to the cardiovascular tissues. They help reduce the blood pressure as well, by lowering cholesterol levels and preventing the hardening of artery walls. This considerably reduces the chances of heart attacks.

Prevents ADHD in Children

Just like in adults, salmon offers the same brain benefits to children. Studies show that the omega-3 fatty acids can improve academic performance while preventing ADHD symptoms.

Skin Care

Owing to high concentrations of omega-3 fatty acids, salmon can reduce inflammation, reduce pore clogging, and erase fine lines and wrinkles. The carotenoid astaxanthin has antioxidant that can reverse the free radical damage, which causes aging. The same antioxidant is also very effective in cases of atopic dermatitis.

Weight Loss

The fish is the right meal choice for those who wish to lose weight and keep it off because of its high protein content, which regulates hormones that control appetite and makes you feel satiated. High-protein foods also increase your metabolic rate. Being low in calories, salmon has polyunsaturated fats that are also known to promote weight loss and target belly fat.

Boosts Metabolism

The omega-3 fatty acids, vitamin D and selenium within salmon all combine to help manage insulin levels throughout the body, thereby facilitating the absorption of sugar and the subsequent lowering of blood sugar levels.


Fights Inflammation

Scientists believe that inflammation is at the root of most chronic illnesses like cardiovascular diseases, diabetes, and cancer. Omega-3 fatty acids reduce inflammation of the arteries and the digestive system, reduce chances of colon, prostate, and kidney cancers. Studies have found that these fatty fish reduced the development of inflammatory markers TNF-a and IL-6 (35).

Decreases Cancer Risk

Salmon is considered a cancer superfood due to its high omega-3 content. There are thousands of scientific papers that have clearly stated the positive effect of omega-3 fatty acids on preventing cancers and tumors. It is important to note that those suffering from cancer experience measurable benefits even if they consume the fish just once a week.

Eye Care

The omega-3 fatty acids and amino acids in this fish help prevent macular degeneration, retinal dryness, loss of vision and fatigue of the eyes. It is a proven fact that people who eat fish regularly, or at least more than others, have better vision than those who don’t.

The fatter the salmon, the more nutritious and healthy it is. It is a good protein supplement for older or sick people as well since it is easy to digest. In some parts of the world, it is cheaper than other sources of animal proteins like red meat and poultry.

Side Effects of Salmon

Mercury poisoning: There are two types of salmon available, wild or farm-raised. Wild salmon is caught in natural water bodies like rivers, lakes, and oceans. Fish farms make up a large part of the salmon sold for consumption worldwide. Studies show that farmed salmon has greater levels of contaminants like polychlorinated biphenyls (PCBs), dioxins, mercury, and several chlorinated pesticides. These pollutants are known to cause various cancers, diabetes, and stroke, among others. Make sure to purchase quality farm-raised salmon, and it should be safe to consume it 5 a week.

Women, who are pregnant or nursing, should keep monitoring their salmon consumption as methylmercury, a toxic form of mercury can have a negative impact on the baby’s developing brain and nervous system.

Tapeworm infection: It’s not safe to eat raw salmon which has brought from the fishmonger or the supermarket. Raw salmon and salmon sashimi are not the same as the sushi-grade fish are kept ‘super frozen’ at minus 40 degrees C. Raw salmon may contain parasitic tapeworms called Diphyllobothrium latum, which can cause:

To avoid this, make sure that you cook the fish thoroughly at its thickest point, cooking for 10 minutes for every inch.

So go ahead and enjoy your salmon baked, grilled, or pan-seared without any guilt!
