Thanks for the explanation. I wrote up some of the details of our approach here. Nutrition is far from being settled, and major discoveries have been made just in the past 50 years. Therefore we take an approach that's fairly conservative, which means (among other things) getting most of our nutrients from whole foods, the way humans have been eating for virtually all of our species' history. We think the burden of proof should be on Soylent to show that their approach is a good one.
