I'm not familiar with the side effects of steroids, etc, but nobody tells pregnant women that they shouldn't eat any salt, any fat, any carbs, etc. Nobody freaked out at a restaurant when my wife ordered a nice ribeye or a piece of chocolate cake.

You miss the point. Without evidence, "they" tell everyone (pregnant or not, male or female) to avoid all sorts of things for imagined or minor harms.

And if you decided to light up and expose others to harmless secondhand smoke, "they" certainly would freak out.
