The Food of the Gods and How It Came to Earth is a science fiction novel by H. G. Wells, first published in 1904. Wells called it "a fantasia on the change of scale in human affairs. ... I had hit upon while working out the possibilities of the near future in a book of speculations called Anticipations (1901)." There have been various B-movie adaptations. The novel is about a group of scientists who invent a food that accelerates the growth of children and turns them into giants when they become adults.
