Although there is no scientific proof to back up the assertion that lobster can induce labor, it does contain high amounts of prostaglandins which have been known to stimulate contractions in certain women. It is very important that women who are pregnant closely monitor what they are eating so they will be able to stay as healthy as possible. It will be crucial to add lots of fruits and vegetables to your diet if you are with child so they will be able to benefit from them nutritionally as well.
Pregnant women will want to avoid eating a lot of lobster for a number of reasons though, including the fact that it tends to have a significant amount of mercury in it which you will obviously want to avoid as it could do damage to you and your unborn child over a long enough period of time.
