Morning
Not an exhaustive list, but here are some guidelines.
Raw fish (sushi) is a no no. The fact is that all meat you have, fish, chicken, pork, beef, etc. needs to be very thoroughly cooked to kill all the bacteria in it. So no rare steak and no sushi binges whilst you have a baby on board.
Also, soft cheeses - Camembert, brie, blue cheese - a no go zone. Again, the bacteria angle is just too high. Gynea said it probably wouldn't do harm if you snuck a bite veeery seldom, but I'm the type that will finish the cheese plate by myself, so no cheesy for me

.
Try and avoid fish with high levels of mercury - tuna and hake are fine, but you can find a lot about that on the internet.
Vitamin A needs to be limited - no liver for you whilst your pregnant (and please, no "afval"...even when you're not pregnant that should never be a meal option, hehehe

). Try getting your vitamin A from veggies instead - carrots and broccoli are good sources.
Lastly - try and stay away from fizzy drinks and artificial sweeteners. They are not only bad for you, but don't help with the inevitable weigh gain

.
Enjoy the pregnancy, when you see that little baby dance for you on the sonar, every thing you are disallowed becomes a non issue.
