Bonnie comments on Consumer Reports position on mercury for pregnant women

According to Consumer Reports, pregnant women should not eat canned tuna because it contains harmful levels of mercury. Taking a more cautious approach than the U.S. government, Consumer Reports claims that due to the FDA findings that 6% of canned light tuna tested exceeded maximum limits of mercury allowed, pregnant women should avoid all forms of tuna.

Bonnie - Whole Foods does a very good job of testing their canned tuna for mercury safety. There are other brands that also list mercury-safe on the label. These should be, not only okay for pregnant women, but recommended as good sources of omega-3 fats. To err on the side of caution, however, I recommend no more than 12 oz. weekly. Pregnant women should never eat raw fish, and sushi tuna and shark/swordfish are the worst from a mercury perspective.
