Seafood or seafood is known as a diverse source of nutrients which include proteins, amino acids, and vitamins and minerals. Marine food is also known to contain functional nutrients that do not exist on animals that live on land.

Seafood Nutritional Benefits For Health

The following is the nutritional content of various seafood and their benefits:


Seafood is a source of high-quality protein because it is generally low in bad fats, and contains amino acids that are easily absorbed and digested by the body. Protein content in seafood is useful for growth in children, adolescents, and even adults. Besides filling, protein in seafood is also good for muscle health and reduces the risk of cardiovascular disease.

All seafood, including all types of fish, contain protein. However, tuna is a type of fish with the best protein, because it contains low fat and calories. Salmon also has the good protein content, in addition to high omega-3 fatty acids.

Omega-3 fatty acids

In addition to proteins and amino acids, such as taurine which is anti-inflammatory and cholesterol-lowering, seafood also has omega-3 fatty acids, which consist of DHA and EPA. Omega-3 fatty acids are essential fats found in fish with red meat, such as tuna, salmon, bloated, tuna, mackerel, Pomfret, skipjack, mackerel, and sardines. Besides fish, other seafood that contains omega-3 acids is oysters, shrimp, and lobster.
There are three types of omega-3 namely alpha-linolenic acid (ALA), EPA, and DHA. EPA and DHA are forms of omega-3 that are commonly found in seafood, whereas ALA is found in many plants, such as flaxseed. A number of studies reveal that omega-3 has many benefits for various diseases, including cancer, asthma, depression, heart disease, ADHD, and rheumatoid arthritis.

EPA is anti-inflammatory, whereas DHA plays an important role in brain health and brain development of children. DHA is widely used for the treatment of dementia, coronary heart disease, and ADHD. DHA is also useful for improving vision, preventing depression, preventing eye diseases associated with age, such as macular degeneration.


Seafood also contains a number of vitamins, such as vitamins A, D, E and B12. Examples of seafood that contain vitamin A are tuna, salmon and tuna. Examples of seafood that contain vitamin D are salmon, tuna, sardines, oysters, and shrimp. Seafood that contains vitamin E includes octopus, salmon, abalone, and lobster. While seafood that contains vitamin B12 includes tuna, tuna, sardines, oysters, and crabs.


Fish and other seafood, including shellfish and shrimp, also contain minerals such as iodine, selenium, calcium, potassium, and iron. Mineral content in seafood is very good for health, for example, iron which is useful to prevent anemia, and iodine to prevent goiter. Examples of seafood that contain high minerals include salmon, sardines, tuna, and tuna.

Carbohydrates and fiber

Although at low levels, seafood also contains carbohydrates and fiber that are good for health. Seaweed has the highest fiber content among other seafood. Besides being processed as food, seaweed is also used for beauty and medicinal products.

Alert Mercury on Seafood

Although fish and other seafood provide many nutrients, some of them have high mercury content and should be avoided especially by pregnant women and children. The types of seafood include sharks, cob, swordfish, marlin, grouper, rays, and snapper.

If you don't like eating seafood, you can get the nutritional content of fish by consuming fish oil supplements or supplements containing DHA. Although good for health, seafood is not recommended to be consumed too often. The recommended amount of consumption is enough 2-3 servings per week, plus other nutritional intakes from fruits, vegetables, and nuts.
