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.

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.
