IIRC the large intestine and colon is more about water resorption than nutrient absorption, and while potassium is a very dangerous electrolyte, I’m doubtful that much of it will get absorbed at all, even if 1 banana could do any damage to the average person with working kidneys.
Doesn’t the colon absorb vitamins better or something? Could you overdose with anal bananas?
