You should always rotate the green
leaves that you add to your smooth-
ies. Almost all greens in the world
contain minute amounts of alkaloids.
Tiny quantities of alkaloids cannot
hurt you, and even strengthen the
immune system. However, if you keep

other single green for many weeks
without rotation, eventually the
same type of alkaloids can accumu-
late in your body and cause unwant-
ed symptoms of poisoning.
