dust and vitamin content?

Question

I've been watching some Little Britain and i've been wondering

"Does dust actually contain some health benefits?"

or would it cause someone to gain weight.

I mean i know you've got your good food yah lectuce, yah Rivita- but would dust cause harm?

Answer 1

Considering that a significant part of household dust is human skin cells would it even be appropriate for veggies? With all the other junk that dust consists of I'd think eating a large quantity wouldn't be very good for you!

Answer 2

Breathing it in could cause problems, but you would not ingest enough to gain any vitamins or calories.

If you tried to eat a big bowl full of dust you would probably choke. I know I do when I eat something powdery.
