Is frozen salmon "bad"

[Lifelong]

I've got an issue with eating heathily so have recently starting buying Aldi's Wild pink Frozen Salmon.

I stick two fillets in tin foil with some seasoning and bake for 25 mins and serve with some boiled eggs + toast/salad.


Is there any harm by eating frozen fillets or should I go for the "fresher" unfrozen stuff? All of that stuff seems to be farmed and I've heard its not as good for you.

Any thoughts and opinions?

Is tinned fish better?

I'm happy to pay for food, but can't be buying fresh fish as that is crazy crazy money.

My main thing is that it is easy to cook. Can you easily heat up tinned fish?
