You may have heard that apple seeds are poisonous. I looked it up here. Although it’s true that apple seeds contain a tiny amount of a cyanide compound, it’s not anything your body can’t absorb in such small amounts. Not to mention the fact that apple seeds have a protective covering that would allow them to make it all the way through your digestive system. (It wouldn’t be in the tree’s best interest to kill us before we could plant the seed.) So go ahead and eat that apple core! (unless you’re a homeopath in which case you believe even one molecule of something can have an effect on you…good luck with that)
