Martijn Belle asked the Naked Scientists:

Dear Naked Scientists,

I want to know the following.

We all know eating fish is healthy for the omega 3 fatty acids.

Are those healthy fats still present in fish like sardines or herrings after they are canned?

Thanks for your answer.

Best regards,

What do you think?

The omega-3 fatty acids should survive the canning process.
Please disregard all previous signatures.

Yes the canned/tinned fish do still contain Omega 3-fatty acids.
But fresh fish is the best way to get the correct vitamins and these fatty or oily acids too.
Rosalind Franklin was my first cousin and one my life's main regrets is that I never met this brilliant and beautiful lady.
She discovered the Single DNA Helix in 1953, then it was taken by Wilkins without her knowledge or agreeement.

The fats in oily fish usually remain in-situ and are stable until we do something terrible to the fish, like deep fat fry it.

This very effectively leaches all of the beneficial fats and replaces them with vegetable (or worse) oils.
