For those who are convinced that wild salmon is healthier than farmed salmon, Dr. Sanjay Gupta says, think again.
"What was surprising to me and I think to a lot of people was that if you compare farm salmon versus wild salmon, there actually wasn't that big a difference between the Omega-3 levels," Gupta tells 60 Minutes Overtime. "The farmed salmon industry has changed what they're feeding their salmon over the years and it's improved."
To those who will refuse farm-raised and only eat wild-caught salmon, Gupta says: "If you're doing it because you think it's better for your health, you'd have a hard time making that case.
"If you're doing it for the wild salmon themselves as opposed to your human health, that's a stronger argument," says Gupta.
