22 Foods You Should Never Eat Raw

Yucca

Just like Chaya, yucca (or cassava root) also contains cyanide, or cyanogenic glycosides to be exact. High levels of the toxin are found in its leaves, which prevents it from being eaten by insects and animals, but some also makes its way into the edible root as well. In order to make this starchy tuber edible, it must be dried, soaked in water, rinsed, and cooked as soon as possible after harvest.
