What foods should pregnant women avoid?

From an analytic viewpoint.  the food that a woman eats normally (out of pregnancy) should be OK during pregnancy too ... BUT ...  there are two considerations that need to be taken into account

1. The state of weakness and fragility (vulnerability) pregnant women get into ... specially in the last ew months before delivery
2. The delicacy of the baby being created inside the woman being fed from what she eats and drinks 

Hence, there are those foods/drinks known to be harmful inluding alcohol, narcotics, tobacco, and some complementary food diets (fabricated ones) 

In additon there are those which are subject to contamination as in the case of raw meat, smoked meat, ,,, etc .. etc
