Actually, we do know!
Caffeine is a very weak (inconsequential) diuretic.
The most common toxin in coffee is OTA, which comes from mold. It’s not regulated in the US, so when China, Japan, and the EU reject moldy coffee, we happily drink it in the US.
And then we pee. Because OTA is a potent bladder and kidney toxin linked to cancer, the body quickly pulls liquid from your plasma (dehydrating) to dilute the toxin, so your kidneys and bladder take less of a hit.
Then your body tells you to pee urgently, even though your bladder isn’t full.
Coffee shouldn’t make you pee. It shouldn’t give you anxiety. It shouldn’t make you crave sugar.
It’s supposed to make you feel dangerously good, not weak!
