I've been eating tuna right out of the can for years. I assume it's already cooked or if it's not that it doesn't matter, because that's how everybody uses it.
Is canned salmon the same? Do you have to cook it or is it good right out of the can?
Also being a poor student and seeing how cheap I can buy canned salmon would there be any ill effects to eating a whole can of the stuff every day (or 4-5 days a week). I think the entire can has about 600 calories, 80-some grams of protein and a good amount of healthy fat.
