July 9, 2020 — It is well known that salmon provides a range of valuable nutrients, including omega-3 fatty acids and protein. But it can be confusing for consumers to know which species offers the highest level of nutrition when they are faced with several different types of salmon at the grocery store.
There are also mixed messages when it comes to farmed salmon, with some people believing it may contain contaminants and is not as nutritious as wild-caught fish.
Consumers can’t look to labels for clarity since nutritional information is not required on seafood packaging in Canada and the United States.
Stefanie Colombo, an assistant professor of Aquaculture at Dalhousie University’s Agriculture Campus, wanted to shed some light on the murky area by exploring the nutritional differences between salmon. Her research, published recently in the Journal of Agriculture and Food Research, produced some surprising findings she hopes may dispel misunderstandings about farmed salmon.
“I get a lot of questions from people I meet about farmed salmon and many people have the idea that it’s not good for you, that it’s full of fat and contaminants,” says Dr. Colombo, who also holds the Canada Research Chair in Aquaculture Nutrition. “I knew these were misconceptions, but I wanted to know how it compared to the other types of salmon that were out there.
