How much Omega 3 does a cheap can of tuna contain?

I was told that experts originally thought that the canning process damaged the Omega 3 but they now know that it doesn't. If this is true then how much Omega 3 does a cheap can of tuna contain?|||To get the most omega 3 fats from your canned tuna, choose water-packed tuna rather than oil-packed. The oil mixes with some of the tuna's natural fat, so when you drain oil-packed tuna, some of its omega 3 fatty acids also go down the drain. Since oil and water don't mix, water-packed tuna won't leach any of its precious omega 3s.





Canned in water and drained, 6 ounces of light meat tuna typically provides a little less than .5 gram of omega 3 fatty acids, while light tuna canned in oil and drained provides a little more than .3 grams of omega 3.
