Soylent, Silicon Valley's favorite meal-replacement drink, is using the boogeyman of ingredients in its product. And no, it's not people. The startup, which has attracted a cult following with its convenient powders and ready-to-drink bottles designed to replace eating actual meals, is made with genetically modified organisms, or GMOs. But are GMOs harmful? The makers of Soylent don't think so. And guess what? Scientists agree. As the company's founders write, "GMOs currently on the market provide ample cases of tangible benefit with relatively negligible risk."
