Don’t believe a word of this.
It conflicts with prior ‘studies’ and illustrates how they STILL know next to nothing about the gut.
It’s both a ‘little’ more complicated and much simpler than what profit-driven research suggests.
I was trying to dig into other research on this, and I am thinking this issue becomes prominent with older people, due to the loss of other processes to mitigate it.
Address those other processes, and you could be back to normal.
Younger people eating a lot of fiber aren’t getting dementia, I wouldn’t think. Heck, I’ve been trying to encourage the short chain fatty acids some of these same bacteria form.
Still, it does seem a legitimate problem for older people, and I’m fast becoming one.
