about the best foods to eat for a healthy heart. One of the suggestions is to eat oily fish such as mackerel or salmon at least twice a week. Can anyone tell me if this has to be fresh fish or does tinned fish do the same job? Can't go to the shops much so tinned would be ideal for me but if not freezer portions.

Tescos, and probably the other supermarkets too, do smallish tins of mackerel in oil or tomato.

If you do choose salmon please avoid the farmed salmon and choose wild salmon. It need not be any more expensive and is far healthier. Most supermarkets sell frozen wild salmon fillets - Tesco often sell a pack of 8 for £5, as an example.
You won't get that nasty white stuff oozing out of it, it is far less flabby and much tastier.
You can also buy tinned wild salmon.

Wild salmon has more of the good oils, farmed salmon has less good oils and more bad fat.

if you get the chance try fresh anchovies. Totally different and I love them.
