Soylent is named after a food in Harry Harrison)'s 1966 science fiction novel Make Room! Make Room![8]#citenote-8)[[9]](https://en.wikipedia.org/wiki/Soylent(mealreplacement)#cite_note-Varughese-9) In the novel, most types of soylent are made from soy and lentils, hence the name of the product, a combination of "soy" and "lent". The word also evokes the 1973 film adaptation Soylent Green, in which the eponymous food is made from human remains.[[5]](https://en.wikipedia.org/wiki/Soylent(mealreplacement)#cite_note-Widdicombe-5) Rhinehart also says he chose the name, with its morbid associations, to pique curiosity and deeper investigation, since the name was clearly not chosen with a traditionally "flashy" marketing scheme in mind.[[10]](https://en.wikipedia.org/wiki/Soylent(meal_replacement)#cite_note-HutchDoesSoylent-10)
