Quick Summary

New research published in Frontiers in Nutrition by the USDA found that farmed Atlantic salmon contains 63.8% less eicosapentaenoic acid (EPA) and 47.5% less docosahexaenoic acid (DHA), key omega-3 fatty acids, compared to older data from federal nutritional sources. This decline is potentially due to changes in fish feed, with an increase in plant-based oils replacing marine fish oils. Celebrity chef Andrew Zimmern cautions against a broad dismissal of farmed salmon and instead advocates for improving aquaculture practices rather than discouraging consumption altogether.

Story summary

A recent USDA-led study published in *Frontiers in Nutrition* revealed that farmed Atlantic salmon contains up to 63.8% less eicosapentaenoic acid (EPA) and 47.5% less docosahexaenoic acid (DHA), key omega-3 fatty acids, compared to older federal nutritional data. The study, which analyzed eight farmed Atlantic salmon fillets from retailers in the mid-Atlantic region, suggests that changes in fish feed could be responsible for these reductions as salmon farms increasingly use plant-based oils instead of marine fish oils. Celebrity chef Andrew Zimmern has pushed back against concerns over farmed salmon, arguing that rather than eliminating it, efforts should focus on improving its nutritional value.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
