What affects baby in utero?

Does any one know if listening to true crime pod casts, with headphones, will affect my baby?

Some of the episodes are pretty gruesome. I turn it off if I can tell I am getting agitated/heart starts to beat a little faster because I assume she will be affected by that. But will it affect her mind/personality if she can’t hear it?

What about eating a lot of sugar?

Any good references for what external things can affect a baby in utero?
