I won't disagree with that entirely but surely it's conceivable that someone with perfect nutrition habits would still catch some kind of bacterial infection that their body is just not equipped to deal with, and they need antibiotics to recover from? I mean I don't believe that human gut bacteria have the potential to become an indomitable defense for any kind of exogenous pathogen, even if, in perfect balance, they might be a solid defence from MOST exogenous pathogens.
I wouldn't dispute that nutrition is of understated importance in today's world. If you have a moment is there any chance you could give a brief summary of what kind of food a typical day would include for you?

I know that probably everyone will have slightly different nutritional requirements but
I'm just very curious now what you're eating, basically, that is as or more effective than any pharmacological aid.
I don't ask this with any intention to try to debunk it just in case it sounds that way (maybe unnecessary to say but am coming down from a cathinone so feeling a bit edgy 8), kind of ironic given the topic under discussion I guess), and I don't have enough knowledge about nutrition even if I wanted to. Just genuinely curious.
