Foods that pose a potential risk due to high vitamin content or toxins:
Patés: Too much vitamin A can harm your developing baby, making liver patés a risky treat.
Exotic fish and tuna: Exotic fish (i.e., swordfish and shark) can contain high levels of mercury, which could be harmful to your unborn baby. Tuna in the form of a cooked steak or a few medium-size cans is OK, but don't go for raw.
