Cherries are easily one of our favorite fruits. They’re sweet, tart, and look adorable. But don’t let its appearance fool you. Those tiny little cherry seeds are dangerously high in hydrogen cyanide, which can make you extremely sick or even kill you, if you happen to eat a broken seed. Chewing on them will do even more harm because it releases the toxic directly into your bloodstream. It’ll take about two broken cherry seeds to cause harm or death to a fully grown adult, but why even risk it? Just avoid it altogether and make sure to spit those suckers out while snacking.
