“I went back in my mind: what am I not eating enough of?” he told me. Definitely not fruits and vegetables: he crams as many as 20 of them, including pulverized banana peels and the ground-up rinds of oranges, into the smoothies he drinks two to three times a day
I would expect banana peels to be quite toxic on average. Lots of pesticides, and unless you live in a place where bananas grow, who knows what they do to the bananas to prepare them for shipping.
Wait, banana peels?
