Meaning
Something that merits serious reflection or gives the mind material to ponder. It appears almost exclusively as the object of 'give', 'offer', or 'provide', said of reports, remarks, statistics, and experiences that leave a lasting impression on the reader or listener. Neutral; a staple of reports, reviews, and speeches, almost always governed by 'give', 'offer', or 'provide'. Regional use: General English.
Origin
The metaphor of reading or ideas as nourishment is very old - Latin ruminare covered both chewing the cud and mulling something over, and English 'chew the cud' long carried the same double sense - and Grammarist notes a spike in such usage in the 1500s. The fixed wording, however, is a 19th-century creation generally credited to Robert Southey's poem A Tale of Paraguay (1825), Canto III of which promises 'A lively tale, and fraught with ... food for thought'. This line is widely reported to be the Oxford English Dictionary's earliest citation of the phrase, and a 2025 George Eliot Review essay likewise notes that the expression entered the nineteenth-century vocabulary through Southey's poem. Southey was condensing a long-standing metaphor into a set phrase rather than inventing the image itself.
