Introduction
Fish, salmon, Atlantic, farmed, cooked, dry heat, and Fish, whitefish, mixed species, cooked, dry heat are the specific food kinds considered in this comparison. In this article, we will discuss their nutritional values and health effects.
Classification
Salmon belongs to the family Salmonidae. There are two types of salmon: Pacific and Atlantic. Pacific salmon are members of the Oncorhynchus genus. Atlantic salmon is a member of the Salmo genus. Atlantic salmon are the largest species in the Salmon genus.
The name Pacific salmon refers to five primary species: King (Chinook), Sockeye (Red), Coho (Silver), Pink (Humpback), and Chum (Dog, Silverbrite). The nutritional values of these spices might vary.

Compared to salmon, whitefish has a higher mercury content (1).
Acidity
The way to determine the acidity of foods is the potential renal acid load or PRAL. The PRAL value of salmon is 14.7. The PRAL value of whitefish is 11.1. Both of them are acidic.
Weight Loss & Diets
As fish is meat, salmon and whitefish are not considered vegan or vegetarian.
Salmon and whitefish are good options for people who follow the pescetarian diet.
Salmon and whitefish are allowed in the Mediterranean diet.

Both whitefish and salmon are paleo-friendly.
Health Impact
Pregnancy
Salmon and whitefish contain less mercury levels. They are the best choices for pregnant women(2).
According to studies, EPA and DHA are essential for healthy embryonic development, including immunological, neural, and retinal function(3).
Cardiovascular Health
According to the study, eating salmon reduced systolic, diastolic, and mean arterial blood pressure. Salmon consumption also decreased LDL-cholesterol and increased HDL-cholesterol(4).
In patients with known coronary heart disease, omega-3 fatty acids reduce the risk of sudden cardiac death and mortality(5).
Omega-3 fatty acids may also improve cardiovascular function, including inflammation, peripheral artery disease, major coronary events, and anticoagulation(3).
Neurodegenerative Diseases
Supplementation of fish products rich in omega-3 fatty acids, such as salmon or whitefish, may slow or prevent neurodegenerative disorders. As mentioned above, salmon contains more omega-3 fatty acids.
A diet high in polyunsaturated omega-3 fatty acids may lower the risk of Parkinson's disease.
According to the study, fatty fish consumption is inversely associated with the incidence of dementia and Alzheimer's disease(6).
Diabetes
Fish high in omega-3 fatty acids is a good choice for people with diabetes. Compared to whitefish, salmon is high in omega-3 DHA and omega-3 EPA.
Consumption of fatty fish, as well as EPA and DHA, was not linked to an increased risk of type 2 diabetes(7). It may reduce inflammation. People with diabetes may choose baked or grilled fish and avoid fried fish(8).
