Copper: The intermediate cause of PET?
#1
Shocked 
In my previous hypothesis I claimed acetylcholine as the cause of PET but this is just one of 3 steps to the root cause.

Now I probably found the 2nd step: copper.

When acetylcholine is the train then copper is the damaged railway.

When you have a damaged railway you slow down the trains (stop drinking coffee because that raises ACh).

I don't know if this nerve damage is a cause of too low or too high copper but it's most likely a lack because copper is needed in the formation of myelin.

You can imagine the nerve as a copper wire where myelin would be the plastic insulator.

Now you maybe remember that scientist Luigi Galvani that experimented with death frogs and electric current.

"The beginning of Galvani's experiments with bioelectricity has a popular legend which says that the Galvani was slowly skinning a frog at a table where he and his wife had been conducting experiments with static electricity by rubbing frog skin. Galvani's assistant touched an exposed sciatic nerve of the frog with a metal scalpel that had picked up a charge. At that moment, they saw sparks and the dead frog's leg kicked as if in life. The observation made the Galvanis the first investigators to appreciate the relationship between electricity and animation—or life."

A damaged myelin sheath in the area of the eustachian tube could innervate the levator veli palatini and/or tensor veli palatini muscle.

Like you would get an electric shock from a damaged electrical cable.

Copper and estrogen

There are many women who report worsened PET after taking a contraceptive pill containing estrogen (Ethinylestradiol for example).

Estrogen increases serum copper but it also seems to deplete liver copper which is the copper storage of the body.

There's also a steep rise in estrogen during pregnany.

Copper and cortisol

Cortisol also seems to decrease copper.

It seems to lower ceruloplasmin, the copper transport protein while estrogen raises ceuloplasmin.

The other way around a high copper level seems to raise the cortisol level.

But too much estrogen raises cortisol which lowers ceruloplasmin.

Copper and soy isoflavones

The soy isoflavones could improve the PET by improving the absorption of copper through the ability of the isoflavones to reduce cupric (divalent) to cuprous (monovalent) copper.

Link between bariatric surgery copper and PET
(thanks to Matt Dawson at the FB group for pointing this out)

Bariatric (weight loss) surgery causes an impaired uptake of copper. And in patients with such a surgery there was a higher count of people getting PET.

I doubt it was just the weight loss that caused a diminishing of the Ostmann's pad of fat around the eustachian tube. Then most people with weight loss would have PET.

So what is the root cause that causes this copper deficiency?

Excess estrogen (can exclude that for me as I'm not a woman and levels are normal)
Gene Mutation that causes low copper
Viral infection that causes low copper
Environmental factors (pesticides [Glyphosate], low copper in food)

Glyphosate can chelate metals and is probably in every non-organic food.

"In aquatic ecosystems, where both heavy metals and glyphosate can co-occur, glyphosate and Roundup can control both the toxicity and the bioavailability of heavy metals, e.g., Cd, Cu, Cr, Ni, Pb, Se, and Zn (Tsui et al. 2005)."
