During pregnancy, what causes a female to get nauseated after eating if she dost ingest some type of green veggie my pregnant fiance get's sick after eating if she dose not eat a green vegetable with every meal. can you tell me why?

That : That is a very good question that I have often thought about. No one knows what evolutionary purpose morning sickness caused, to be sure. It was probably to avoid certain poisonous types of food that were bad for pregnancy. Some women get no morning sickness at all, and some women get such severe morning sickness they can only have tube-feedings. Women crave and are repulsed by completely diffferent types of foods. Some women can't eat vegetables, some crave them; some women can't eat meat, some crave it. It is very variable but may have to do with nutritional issues and evolution; no one knows for sure. I hope your fiancee is feeling better soon; morning sickness usually improves by 12-14 weeks.
