Is it possible that these peptides or perhaps opiates may
confuse neurotransmitting in the body (as morphine ?)
even if they don't reach the brain.
However, the blood-brain barriere is not perfect.(as would not
the blood - spine, or the probably existing the blood-gut-
neurocentre barriere be) Will it not be challengend  by any
exessive blood carried substance, beening milk prtoteins or
other substances which  are not naturalally placed elsewhere
by 'the body' ?
