too white

I posted the thread on another forum but got no response.
Is the paragraph natural English?

We didn’t know that disposable chopsticks can be dangerous to health until we took the science class. After all, most of us spend a sizable part of the day away from home, so it’s inevitable that we eat out, as well. It’s hard to distinguish the harmful chopsticks just by appearance. But people had better not choose the ones that look too white and perfectly smooth.
