If you read the study they link, it explains the immune boosting/modulating functions of the honey.
Example: Furthermore, the ability of honey to reduce ‘reactive intermediates release’[23] may well limit tissue damage by activated macrophages during wound healing. Thus, the immunomodulatory property of honey is relevant to wound repair.
I've seen this stuff work for wound repair first hand, and I've read enough first hand accounts of people successfully treating gut-related diseases with the help of this stuff.. so maybe don't dismiss it just yet, but if this gets very popular, I don't think NZ will be able to keep up.. the prices on the stuff are already a bit much for any average shopper.
Yes, the testing isn't perfect, but at least it's something, and for many people with diseases like ulcerative colitis, where the doctor's recommendation is to remove the entire colon, this honey has offered many an alternative way to manage their disease and keep their colon.
Now, if it were me, personally I would try the honey first, even if it's never been through clinical trials, before removing my entire colon. I mean worse case I eat a bunch of honey.
I get where you're coming from, but until the science is there, there's no reason not to try foods that we already consume regularly.
My BS detector goes off whenever I see a phrase like that.
The human immune system is just that a system and the word system seems to be glossed over as if it's a thing not a bunch of separate parts.
From the smallest molecule to larger cells it's an incredibly complex bunch of biological process and one food affecting all of it simultaneously is probably not true.
