Tuna in vegetable oil (drained) removes the Omega 3 and replaces it with Omega 6

Canned fish

Please excuse the shout but this is something people should know about -

TUNA IN VEGETABLE OIL (drained)-
YOU MAY BE BETTER OFF EATING BREAST OF GRAIN FED CHICKEN !

In the bizarre way life works, whilst looking for information on lipids in fish skin I have just accidentally found a book that gives very useful information on the effect of cooking including microwaving and canning.

[The effects of cooking on fish is a subject I have searched quite a lot on but never found this book (-:]].

CANNED FISH
WE NEED BETTER LABELLING !!!

Tuna is one of the most popular fishes in the US.

We are overfishing a precious resource which has a medium mercury pollution risk. We are taking out the Omega 3 with vegetable oil, throwing the Omega 3 with the vegetable oil down the sink, and leaving the Omega 6 from the vegetable oil in the tuna.

We then tell people to eat canned tuna (in oil)to get more Omega 3, but we have removed the Omega 3 and replaced it with Omega 6, (how ironic is that,) and then just for good measure we warn people about the mercury content of tuna (A medium risk fish).

Here is a thread on the impact of excess Omega 6 and a lack of Omega 3 on THE RISK OF BREAST CANCER and the situation is similar for PROSTATE CANCER.

AND I have checked on Nutrition Data -

SPEECHLESS.

What a travesty at every level.

Tuna in oil (drained) now has a worse Omega 6 profile than breast and skin of industrial grain raised chicken.

The Book
Getting back to the very useful paper in the book "Omega 3 fatty acid research" By M. C. Teale

They Anna Kolakowska, Zdzislaw Domiszewski and Grzegorz Bienkiewicz say:

Canning can reduce DHA by up to 40%.

Canning in oil can transfer a significant portion of Omega 3s to the oil ( which we often throw away, and most vegetable oils used will be high in Omega 6. - so only buy tuna in good quality olive oil and use the oil.)

Commercially caned tuna may have almost NO Omega 3, which is evidenced above.

In contrast sardines in olive oil may have as much as fresh fish, (presumably that included the oil.)

It is easiest if you read it yourself. Much of the above book is free at the above link.

Where can you find tunafish in olive oil? I have never seen this.
Thank you for this interesting data!

[Rich66]

Seems safer to buy tuna in water and add whatever oil you want to it. Then you know what you've got. Who knows what quality olive oil they use in canning..when they use it.

[caya]

I always buy tuna in water - good to know this is the right thing to do, and as Rich says - add your own EVOO - then you'll know it's good.

all the best

I always buy tuna in olive oil.I then drain it and mix in a bit of EVOO before using it. Wondering if this is a good idea?
Seems fish oil supplements still come out on top especially if they are the pure ones, otherwise it seems we are literally swimming in omega 6!

Goodness...just when we think we are doing something good for ourselves...I totally agree about the labelling. Just tell the truth!!! We are still taking our supplements, even though they are pricey/

[Ruth]

I used to buy tuna in water but thought that after reading that I should purchase it in oil for the health benefits. It just really ticks me off that they aren't true to what it is! AHH. Guess I am back to water and adding the olive oil what I used to do!

[R.B.]

Ellie swimming in it is very appropriate. (-:

The book I give a link to suggests oils leach the Omega3 from the fish, but you don't know the quality of the olive oil. As long as the olive it not one that is cut with Omega 6 I would keep the oil, (and you will just have to take a gut view on that.) It may also contain other fat soluble nutrients vit d etc.

These guys provide quality products at good prices including bottled this oil which is much the cheapest way to take it. With more refining it tastes of nothing and DOES NOT REPEAT (-:

I only eat canned tuna in water. And not very often.
