Fish oil ?

I’ve seen this question asked before, but I’ve
never seen a good answer. Does the heat from
the canning process of fish (salmon) damage
the EFAs in it? I always read that EFAs are
damaged by heat, and canning fish involves
heat. So does canned salmon still retain all
the EFA benefits, or are the EFAs in canned
salmon no good? Thanks.

Heat damages or degraded EFAs over long period of time. How long? I don’t know for sure. Just check the can to see when it was packed. I wouldn’t eat canned fatty fish sitting on the shelf longer than 3 months. If buying bulk, keep cans in a cool place away from heat. If you have ever smelled rancid fish oil, you will understand. Hope that helps.
