The Benefits of Consuming Shellfish

Shellfish and Cardiovascular Health

Shellfish are high in in both B12 and Omega 3 fatty Acids.

  • Deficiency in B12 is a risk factor for cardiovascular disease. B12 deficiencies are associated with fatal and non-fatal coronary disease, myocardial infarction, stroke, and other circulatory health problems. (1) The only dietary sources of B12 are animal sources, and shellfish are among the best.
  • Omega 3s have been shown to improve your cholesterol profile by reducing triglyceride levels and raising your good HDL cholesterol. (2) Consumption of omega 3s from marine sources is associated with reduced risk of heart attack and stroke.
    • One study on Chinese men showed that consumption of the recommended two servings of shellfish reduced the risk of deadly heart attack by 59 percent! (3)

Shellfish and Brain Function and Health

Vitamin B12 is considered one of the most crucial nutrients for brain function, as it supports a number of metabolic functions that provide your brain with the nutrients it needs.

  • Methlymalonate, a biomarker for B12 deficiencies, may reduce total brain volume and cognitive performance (4)
The Omega 3 DHA is regarded as the most important omega 3 for brain function since it is found at higher concentrations in the brain than other types of omega 3s. Marine sources exclusively provide significant levels of DHA and EPA. Plant sources provide a type of omega 3 called ALA that has to be converted into EPA, then into DHA, losing value through inefficient conversion. By obtaining the source directly from marine animals, you can help maintain healthy levels of DHA. (5)

Shellfish and Immune Health

Shellfish, including mussels, crabs, and lobsters, are some of the best sources of zinc. Zinc promotes immune function by supporting reactions involved in fighting infection and ridding the body of foreign pathogens. (6)

Shellfish and Mental Health

Shellfish, like most seafood, have been shown to support mental health through their omega 3 fatty acids. Consumption of marine-sourced omega 3s is linked to reduced instances of anxiety and depression. (7, 8)
