We are actually what we eat?

Back when I first learned about the theory that matter can’t be destroyed or created, I got to wondering: what about a fetus growing in the womb? That’s when it finally sunk in that the food our mothers eat when they’re pregnant are broken down, rearranged, and become the building blocks for a new human being.

Right? Am I the only one freaking out about this?
I’ll be back in a little while, I’m curious to see responses…
