What is the main reason to sterilise the upper intestine?

Been working on microbiome/gut, and it’s improved, just got back latest stool test.

Still have some blasto parasite, but that’s ok, whilst gut lining still needs lots more good bacteria

All signs of candida gone which was main thing

Also did a hair test, and found both mercury and uranium in levels too high. Heavy metal exposure not good at all

I learnt that mercury from fish in your system can be 5 years old

I also think it’s part of the shit they’re spraying in the skies

So got to get a handle on the heavy metals next
