The idea that has me interested in bad gut bacteria theory is the overgrowth of candida.I'm starting a candida diet. It certainly can't hurt to try. I have eliminated sugar, simple carbs and alcohol so far. Not that I was much of a drinker but I do like a cold beer on a warm day . There are definitely accounts of pwp and a connection to the gut. The candida fight your body for good nutrients thereby allowing toxins to flourish as your body can't fight it.

I have had signs of candidiasis prior to being diagnosed. I have had Tinea Versicolor (fungus on the skin), toenail fungus and oral thrush. The oral thrush was with a really bad cold. A few years before my symptoms I had Salmonella from traveling to Mumbai. I was given antibiotics which candida loves. Who knows, was that a starting point? That was a few years prior to being diagnosed.

I'm not a huge sugar eater but I love simple carbs.

What's the connection to the brain? Maybe the vagus nerve.

There are also anecdotal cases of pwp taking anti-fungal meds and doing very well until they stop. Kind of like cutting the grass with weeds and not addressing the weeds with anything, they will return.
