2. Lima beans
Almost all of us have grown up being forced to consume Lima beans, and let’s hope that your mother or grandmother was careful when preparing them because they are really dangerous when eaten raw.
This type of legumes contains a compound known by most doctors as linamarin. This compound basically breaks down into cyanide, which is a rapidly acting and quite deadly chemical that can occur in various forms.
When cooked properly (10 to 20 minutes), Lima beans do wonders for your health, and they become completely harmless after cooking.
