The standard four food groups are based on American agricultural lobbies. Why do we have a milk group? Because we have a National Dairy Council. Why do we have a meat group? Because we have an extremely powerful meat lobby.
—Marion Nestle
conceit
A fanciful poetic image or metaphor that likens one thing to something else that is seemingly very different. An example of a conceit can be found in Shakespeare's sonnet "Shall I compare thee to a summer's day?" and in Emily Dickinson's poem "There is no frigate like a book."
