But what about the safety of the fish supply in general? Tracy adds, "Unfortunately, fish during pregnancy (raw or cooked) can have PCB and chemical contamination. So contact the Environmental Protection Agency (EPA) or your local health department for a list of fish in your area that haven't been contaminated."
But there's more to sushi than just the fish! Seaweed, used in many sushi varieties, is rich in calcium -- as well as phosphorus, iron, iodine and carotene. It's also one of the best sources of vegetable protein and vitamin B-12. In fact, when it comes to vitamins and important trace minerals, seaweed packs a stronger punch than any other food, according to a USGS report by Phyllis A Lyday. The caveat: while seaweed is high in calcium, fiber and other nutrients, it may also be high in sodium. Talk to your caregiver to find out if this is a concern for you.
