Yes, but how many of those people have chronic diseases that could be eased or even altogether avoided because of poor nutrition. I'm sure anyone who looked into it would be shocked to find out the number of cardiovascular diseases that could be ameliorated by simply eating better. Soylent being an adequate replacement for ramen noodles and a Big Gulp doesn't make it healthy. Anyway, I doubt anyone gives a shit about this particular guy's health outside of his inner circle, but lots of people care about public health generally, and I don't know too many of them who would advocate a soylent-based lifestyle.If you can survive on what most Americans or Somalians eat, you can surely survive on Soylent.
This way of thinking informs our discussions in politics as well. Asking "Is it good?" or "Is it healthy?" means little if you do not first answer "Compared to what?" So I suggest we ask is "Is it better?" And I believe it is more useful to compare to what actually exists than to an idealized vision of what could be. If you are concerned about cardiovascular health, Soylent may well represent eating better for many people. The significant negative mentioned is the 350 grams of sodium. This does not look so bad compared to 908 mg in a Big Mac, 875 mg in ramen, 280 mg in a Caesar salad, or 2 grams in a Chipotle burrito.
