Omega 3 in fish

[jpipw]

I bought a copy of Gordon Ramsey's Healthy Appetite from the charity shop the other day and in it he writes about oily fish saying " The fish must, however be fresh - tinned tuna, sardines etc., won't give you the same benefits because most of those omega-3's are lost in the canning process".

Does anyone know of any reliable figure for the difference between the omega 3 content in fresh sardines and tinned ones. I used to use the Food-a-pedia from the US government but its been taken down and replaced with a less informative web site.

Hi jpipw

I just had a quick look at some articles about Omega 3 in canned fish products, and there are a few about. But in terms of your query about a reliable figure for the difference between the omega 3 content in fresh sardines and tinned ones - I hope someone can help.

There is an article about Tuna here that you might find interesting - it has a few references at the bottom as well, but again, I don't know the reliability of the information - but I hope you might find it interesting:

Welcome to the Healthy eating forum, and I hope you enjoy the book 'Healthy Appetite' - it sounds like an interesting one.

I've found the info on the USDA food composition database and I think that its probably not a clear cut thing. Tuna can be from several different types and the omega 3 varies between them and likewise in the tinning. For sardines there simply is no data other than for tinned and this shows a fairly healthy amount although more in the ones with tomato sauce. This is supposedly because the omega 3 leaches into the oil and may be tipped away.

I have been looking at where their sourced from since it was pointed out that mercury is a contaminant of tinned fish. Notice that Aldi has switched its labels to say which zone they come from so now I only get baltic sardines ( Brisling ) . Not much point getting good oil if its already contaminated .

If it is omega 3 you are after, you don't have to get it from fish and you can get it from various seeds or even algae like spirulina or chlorella.

Vegans obviously don't eat fish so how would they get omega 3?... Through what I just mentioned. Various seeds, chia seeds, flaxseed, hemp...etc
