Women who are pregnant should probably avoid eating pork for a number of reasons, including the fact that it can expose you to a number of parasites, even after it has been cooked.
This particular type of meat has also been known to increase cholesterol levels, which is certainly something that women who are pregnant will want to stay away from.
Pregnant women tend to become more susceptible to food borne illnesses because of their lowered immune system, so it is a good idea overall to avoid eating pork for the duration of your pregnancy. This way you will be able to decrease the chances of any health problems or complications.
