Hi @cahlen,
Big ingredient list indeed :p
(you didn't detailed the multivitamin part)
I think I understand your idea behind this brew, it looks quiet balanced.
But despite the many advantages of this mix, (ease of transport, no hot water need, balanced food)
I don't think it's a good thing to only drink this on the long term.
Physiology is a complex machinery and it need variations on intakes.
My main worry would be on long term impact on kidney and liver witch can become very quietly without you noticing that much.
A second rank would be teeth.
With this diet you have no chewing. (maybe find something to chew during the day)
This being said, despite my worry on long term effect and my distrust of processed / chemical food,
I think I'll make some of your magic powder (but more for a SHTF situation).
