Why are hare lips such a common birth defect, is it something that the mom eats during pregnancy?

In brief: No known food causes

Cleft lip occurs when left, right, and upper parts of the lip do not fuse properly in an embryo.
No foods are known to cause it. Maternal smoking and alcohol/drug abuse increase the chances of a cleft. Cleft lip runs in some families, but can also happen in a variety of genetic mutations. It occurs least in africans (<1 in 1000 births) and most in oriental asians and native americans (3-4/1000).
