There has been a tremendous amount of skepticism since Rob Rhinehart invented his Soylent drink and claimed he’d been living on it 90% of the time for seven months. He defends himself and his invention against criticsm from Four Hour Work Week author Tim Ferriss at his blog:

In 1828, a young organic chemist named Friedrich Wöhler committed heresy. Wöhler accidentally synthesized Urea, a component of many lifeforms, from inorganic components. At the time everyone knew there was a special “life force” that separated organisms from other matter. It was a long uphill battle to convince the scientific community, but eventually the evidence won out. Regardless, even today many laymen tacitly assume that the holistic makeup of lifeforms such as food rise magically above their constituent chemicals.
Everything is made of parts. The idea of holistic food represents the death throes of Vitalism, the fallacious assumption that there is something materially special about forms of life separate from other forms of matter. This is an easy mistake to make. Humans and animals move, breathe, and mate, unlike rocks or soil, but we’re all made of the same interchangeable forms of matter and energy. A stone dropped in to a pond will take the shortest path to the bottom. A human will take the shortest route to work, and cling to old ideas. Life is complex, but there is nothing about it that disobeys well understood laws of chemistry and physics. I am not sure if consciousness is reducible, but carrots certainly are.
Creating a lifeform from scratch is an elusive task, and though great strides have been made recently we still have limits in our understanding. However, you do not need to fully understand an organism to feed it. Bacteria grown in labs are always grown on a synthetic medium of nutrients called “LB”. Pets live on synthetic diets and are much healthier and long-lived than their wild counterparts. We don’t know how proteins fold but we do know all the metabolic pathways of a human, and our complete elemental makeup, thanks to elemental analysis. Even the grand diversity of the human microbiome contains conserved metabolic pathways. We do not yet know what the ideal diet for a human is, but our present understanding permits us to easily design a diet that is far superior to what most people are eating.
Humans have lived on animal flesh and the reproductive organs of plants for a long time, but food has been changing all along. And it still is. The development of agriculture, then preservation, then nutrition, then processing, and now even biotechnology have all vastly improved our food products and lifestyle over their natural forms and immensely increased the carrying capacity of the earth. In fact, the foods we thrive on today are far from natural. How do you think bananas reproduce without seeds? The United States began adding Niacin to bread in 1938, which largely eliminated the deadly disease Pellagra, and iodized salt likely has a lot to do with the steady rise in IQ seen in the last century.
This is not to say that all new foods are healthy. Many food companies design purely for the sensory experience of food, leading to products that are over-stimulating, unbalanced, or even addictive. I am amazed that we have cheap chocolate bars, which would have been a kingly delicacy not long ago, but I think we deserve new healthy options as well…
