Your neighbor is talking about a toxin called phytohaemagglutinin, also known as kidney bean lectin, that is found in many types of beans. Kidney beans contain especially large amounts of this toxin, and amazingly, eating just four or five raw or improperly cooked kidney beans can make a person extremely ill. Ingesting larger amounts can actually cause death. Other beans, including white kidney beans, broad beans and lima beans, contain the same toxin in smaller but still dangerous amounts.
