"Nuts" has several different meanings, depending on the content. - It can refer to the food category of nuts (walnuts, peanuts, almonds, et cetera) - It can refer to someone "being nuts" ("That man its nuts!") -- meaning someone is crazy or insane - It can also be used as a slang word in reference to male genitalia - I have also heard it used before as an exclamation of frustration. For example, if someone makes a mistake, they may say, "Nuts!" This is rather uncommon, though. Does this answer your question?
