Did Buffy the Vampire Slayer pave the way for Beyond Meat and Impossible Burgers?

Season 6, Episode 12 of Buffy found Sarah Michelle Gellar's character working at Doublemeat Palace fast-food restaurant. During her shifts, says Madeleine Davies, "our plucky slayer notices a pattern of disappearing employees, leading her to suspect that the secret ingredient is PEOPLE. But it’s not actually people. The burger doesn’t actually contain beef or chicken. After having Willow (still good/not yet turned dark and veiny) analyze the meat patties, they discover that it’s actually cellulose, a chemical compound found in green plants. Bamboo cellulose is an ingredient in Beyond Meat, and methylcellulose (a cellulose derivative typically known as a laxative) is found in both Beyond Meat and Impossible Burgers."
