Activated Charcoal
Although I wouldn’t consider this a “food” per se, it is edible and great for your body. The activatedness of it binds to heavy metals and removes them from your body.
As part of the 15-day raw vegan body detox, the first five days focused on cleansing the bowels and an activated charcoal powder was taken with fresh juice five times daily. My poop was black but I knew my bowels were being cleaned from the inside out!
