Is it ok to eat canned tuna at nine months pregnant

In moderation. It is the mercury level you worry about but one serving no more than once a week is okay- or it was according to my OB 4 years ago. ;0)

As long as you're not eating canned tuna 3 times a day, every day, you're just fine! Everything in moderation. The only fish I was told to stay away from completely during pregnancy was swordfish, king mackerel, shark, and tilefish because they have extremely high levels of mercury. I ate tuna occasionally, tilapia almost weekly, and shrimp quite a bit with my last pregnancy, and I just had a healthy baby girl in December.

Canned tuna has less mercury than fresh. I was told up to 12 ounces a week was safe to eat. Good thing too - I craved tuna noodle casserole BAD.

as long as you're not eating it all the time every once in while is okay but if you really want to make sure then you should ask you'r OB

Yes but only once a week

A can of tuna once a month won't be a problem. You also want to stay away from cold cuts, because of the sodium content.
