What factor is immensely important beyond total fat content when evaluating fish health benefits?

Answer

The ratio of beneficial polyunsaturated fats, specifically the Omega-3s, against the Omega-6s.

While the absolute quantity of fat is a factor, the critical determinant for health benefits when consuming fish, especially salmon, lies in the composition of those fats. Health experts focus heavily on the balance between Omega-3 essential fatty acids, such as DHA and EPA, and Omega-6 fatty acids. A favorable ratio, meaning a relatively high amount of Omega-3s compared to Omega-6s, is what provides the sought-after anti-inflammatory benefits. If a fillet has a high total fat but a poor Omega-6 to Omega-3 ratio due to diet, its nutritional value is diminished compared to a leaner fillet with a superior ratio.
