is it true that some food items lead to miscarriages if consumed in early days of pregnancy?

When you are pregnant, people around you will start to advice you like they own a Sinsey shop. Dont eat this and that, its not good for baby, dont drink this and that lah. You know what, i ditch everything away, i ate whatever i feel like, i was very happy and cheerful during my pregnancy, i gained weight but i dont mind. My baby is healthy when he was born, and he is as healthy as he can be now, my 16months old baby. And i managed to lose my weight to the weight i was before pregnant.
