Why does Sockeye salmon generally contain a higher total concentration of Omega-3 fatty acids per serving than Keta salmon?

Sockeye generally edges out Keta due to its higher overall fat concentration.

While both Sockeye and Keta are excellent sources of high-quality protein and vital Omega-3 fatty acids essential for heart and brain health, Sockeye typically leads in total Omega-3 content per serving. This advantage stems directly from Sockeye's inherent characteristic of having a higher fat concentration overall compared to the leaner Keta variety. Consumers prioritizing the maximum concentration of these beneficial oils in a single serving often find Sockeye to be the optimal choice among the wild-caught options, although Keta remains highly healthy by offering substantial amounts of these fats with fewer overall calories.
