Bad news for tuna lovers:
tuna may be not such a good source of omega 3s (but still a good, cheap and convenient source of proteins)
I read that article on Q/A site
I'm glad to be the bearer of good news on this one! Although tinned tuna isn't as rich in omega 3 fats as fresh, it's not the same situation for tinned pilchards, sild or sardines (or herrings or mackerel for that matter). So you can buy these fish on a budget and still get all the nutritional benefits of the more expensive fresh type.
According to the omega 3 information service the reason that tuna loses its omega 3s on canning whereas the others don't is that tuna is cooked before it goes into the can.
Of all the tinned oily fish it's hard to beat pilchards. Although they aren't quite as high in omega 3s as, say, mackerel, they provide a really good source of omega 3s and eaten with the dissolved bones are a rich source of minerals.
Four sardines provide more than 50 per cent the Recommended Daily Allowance for calcium (necessary for strong bones and teeth), a third of the RDA for iron (prevents anaemia), and 20 per cent of the RDA for zinc (essential for healthy skin, immune and reproductive systems).
Don't give up on tinned tuna altogether though; one serving provides the Recommended Daily Allowance of vitamin D and is also a rich source of selenium - an antioxidant credited with reducing rates of heart disease and cancer.
