Its creators state that Soylent meets all nutritional requirements for an average adult. It includes all of the elements of a healthy diet, without excess amounts of sugars, saturated fats, or cholesterol. It was created by software engineer Rob Rhinehart as a self-experiment in nutrition and is now marketed and sold by Rosa Labs. As of 2015, there is no published scientific evidence on the risks or benefits of Soylent itself. The manufacturer says it is based on recommendations of the Institute of Medicine and that it is approved as a food by the U.S. Food and Drug Administration.
