Soylent

As humanity looked toward the stars and prepared for further exploration, tradition forms of food were deemed too inefficient and energy intensive to produce (especially meat). Soylent, a bland, plant-based liquid containing 100% of a human's dietary requirements, was selected as the replacement. Naturally, this resulted in widespread riots and outcries of cultural suppression. The spread of revolt was prevented by reducing the rations given to rioting sectors. Eventually, the dissenters caved in and resentment for Soylent passed as the next generation was brought up on specifically designed, infant Soylent.
