8. Lima Beans
Lima beans may be one of those things that most people either love or hate, with the haters probably outnumbering the lovers by a wide margin. While they may be healthy when cooked properly, these beans are not the type you want to be eating fresh out of the garden. Prior to being properly cooked, lima beans contain something called linamarin, which may not sound all that bad until you find out that it turns into hydrogen cyanide after it is eaten. The word “cyanide” is all you should need to hear to know that it is something you should stay far away from.
