What variable determines the superiority of one fish over another in health attributes, according to one source referencing experts?

Answer

Preparation and sourcing

Determining which fish is definitively 'better' is rarely a simple binary choice based solely on species name. Experts emphasize that context matters immensely when evaluating the final nutritional outcome and overall health attributes of fish like salmon. The superiority or comparative benefit of one fish versus another often hinges less on inherent species differences and more on external factors related to its journey to the plate. Specifically, the way the fish is prepared, which can affect nutrient retention or addition, alongside the sourcing context (where it came from and how it was raised or caught), dictates the ultimate nutritional value observed.
