Breath said: 'What shall be my food?' They answered: 'Whatever there is, even unto dogs and birds.' Therefore this is food for Ana (the breather). His name is clearly Ana. To him who knows this there is nothing that is not (proper) food.

In plain words: Breath asked what its food would be. The senses said everything, even what dogs and birds eat. So breath is called Ana, the breather or eater, and for someone who knows this, no food is improper.
