The husk is commonly removed in the mouth by cracking with ones teeth and spitting out the shell, while keeping the nutritious kernel in the mouth. Sunflower seeds are commonly eaten as a healthy snack as well as being included in bread mixes, used as garnishes or as an ingredient in various recipes. Seeds can also be sprouted and used in salads, however eating old sunflower seeds can lead to stomach upsets or even more serious problems.
