Why did the ban on Pork skip Christianity but come back with Islam?

Hello!

I teach Global History to High Schoolers and during our World Religions unit we group the three Abrahamic Religions together so that students can see the progression of the original ideas through three different religions.

However, for some reason this year I randomly had this thought that I can't find a clear answer on. In Judaism, it is against traditional law to eat Pork, and the same is true in Islam. Why then did Christians skip this part of the tradition? And how did it come back during the founding of Islam?
