Food coloring....
As in FOOD.... consumption, digestion.
Inhaling is totally different, or we could breath with our Bellies and inhale our food !
Im in the belief if it dont "Need" to be there, whats the point ?
Color will not change the taste, so why would I need it ?
We really dont know long term what any of this does to us..... so Im trying to limit exposure to things I dont need.
Besides....
Most of my mixes change into a Lovely color on their own.
Just MHO.............
