I love tuna! I haven't had any in a while, though. A few months before I got preg, I found small (tuna-size) cans of wild caught Alaska salmon at Costco, and we switched. It's a decent substitute, but the flavor is NOT the same. I've actually been thinking about buying a can or 2 of tuna once in a while anyway. With my 1st preg, I ate tuna about 3 times a month. The main reason we switched is because I read that 1 out of 6 cans of tuna has more mercury than it should and dd likes it, too. I was more concerned about her than me. I'm not completely opposed to eating canned tuna though. Just strongly limiting.
