FRIDAY FEB 29, 2008 (Foodconsumer.org) -- Compared to wild salmon fish, farmed salmon fish contains less beneficial fatty acids that may better human heart health, a new study suggests.
The doctoral study by Sverre Ludvig Seierstad at the Norwegian Shool of veterinary Science showed patients eating a diet with salmon meat containing pure fish oil had a better profile of biomarkers for heart and vessel health compared to those who used diets with Salmon meat containing high vegetable oil.
Vegetable oil has found increasing applications in fish farming as the marine source as fish feed has become scarce and expensive. The study wanted to see how vegetable oil in fish feed could impact the health of consumers and the fish.
But the study found the composition of fats in the feed had no effect on the development of constriction in the cardiac arteries of farmed salmon.
Framed salmon fish is still commonly consumed although studies have showed that farmed salmon is more contaminated with environmental pollutants than wild salmon.
