Answer 1

The fetus and mother have separate blood supplies, which never mix. Nutrients from momma are absorbed into the fetus via the placenta and umbilical cord.

So with totally separate systems, mom can eat anything that doesn’t pass through that system.

Be warned that alcohol and nicotine, and drugs of all sorts (otc, prescribed, illegal) are able to get to the fetus.
