Beyond Meat and Impossible Foods are both companies producing a synthetic ground meat substitute that somewhat looks and tastes like real beef. The hubris surrounding these companies' product releases was pretty amazing. Both companies believe their products will save the world, and for a time, they were able to attract many celebrity endorsements and investors. They believe ending animal agriculture will solve humanity's environmental problems and see their products as a more ethical substitute. So, what are these magically virtuous products? Beyond burgers are mostly made of pea and rice protein, and canola and coconut oil. Impossible burgers are made with soy protein, sunflower oil, and coconut oil. Both fake meat products "bleed."Beyond uses beet juice to achieve this, while Impossible uses heme, a flavoring created from a genetically modified yeast.
