"Food for Thought" is a song by British reggae band UB40, released as their debut single in February 1980 from their album Signing Off.

[2] The inspiration for "Food for Thought" is said to have come from the genocide in Cambodia, then known as Kampuchea, undertaken by members of the ruling Communist Party, known as the Khmer Rouge, whose totalitarian government saw between 1.5 and 3 million people killed between 1975 and 1979.

[9] Prior to recording the song, the band had a debate over the subtlety of the lyrics, with Campbell since regretting the ambiguity of them, saying "I find it incredible that people can’t understand it and that upsets me.

[3][10] "Food for Thought" was released as a double A-side single with "King" on local independent label Graduate Records.

[12] The single performed even better in New Zealand where it topped the charts for four weeks and became the first hit there on an English independent label.
