The novel The Food of the Gods and How It Came to Earth by H. G. Wells describes a kind of food that can accelerate and extend the growth process, which when introduced to the world causes great upheavals. In Wells' novel, giants have great powers, and they seek to continue growing and improving; only the small people with their small minds stand in their way. This is a symbol of social groups with great potential suppressed by mainstream society, and an expectation for them to eventually change the world in a radical way. Though one of Wells' lesser-known works, many of the features of the novel have been incorporated into other works.
