United StatesNew research suggests that farmed salmon may no longer provide the same level of heart-healthy omega-3 fatty acids as previously believed, potentially undermining dietary guidelines that recommend increased salmon consumption. The study, led by USDA scientists, indicates that changes in the feed composition of farmed salmon, shifting from small fish to plant-based ingredients like soy and canola, have reduced omega-3 content. This shift follows a significant increase in farmed salmon production, which now accounts for nearly 70% of global salmon consumption. While the study acknowledges the need for further research before revising dietary guidelines, concerns have been raised about the environmental impact of farmed salmon, including pollution and depletion of wild fish stocks.
