What foods should pregnant women avoid to prevent miscarriage?

Patient's question:

No

Doctor's answer:

Foods that may cause miscarriage: crabs, softshell turtles, purslane, and coix seed. These foods have the effects of invigorating blood and removing blood stasis, and they also stimulate the smooth muscles of the uterus, which can promote uterine contractions and thus may induce miscarriage.
