If a person is new to sardines a less pungent way to start is with fillets. Made from the larger sardines not quite as much skin and head like the little ones. The little ones are probably better health wise but I don't know that for sure. They are sourced from all over the world and usually on the can they will tell where they are from. I especially like the Brunswick brand which is Canadian and at least the ones I have eaten of theirs were sourced from Canada. But Amazon was out of the ones in water or olive oil which are the only ones we buy. 

So this dozen can box we went with Chicken of the Sea which is a really cheap brand. A little over a dollar a can off Amazon. I've had them before while in Bonaire and they are "ok". Just a little stronger flavor.

Carolynn can tolerate sardines but I would not say she is a big fan. I actually like them. But what we started doing in Bonaire for daily lunch was a can of sardines mixed with a can of chunk light tuna and made into a tuna salad with some sour cream, mustard, a little vinegar or dill pickle juice and diced up dill pickles or relish. She actually liked it that way and we ate it a number of days that way. Pork rinds for chips to dip it in. Was good and we got some Omega 3 oils for health to boot. Was about the right amount for two of us for lunch. The tuna mixed in makes the sardines a lot more mild flavor.
