I think the issue of variety of food is overlooked. My family back in the countryside has orchards of various fruits. When it's cherry season, everyone is eating pounds of cherries every day... till that 2 week season is over and you don't touch a fresh cherry for another year. I can't help but thing this functions as some natural cleansing process. For me, something like Soylent reminds me of when I prepared bottles for my baby. An all-in-one food was her primary formulation for the first 6 months of her life. But even in that case, there's more variety: because she breastfed. So her nutrients changed from day to day depending on what my wife ate, and slowly changing over the weeks to match her developmental stages. To assume that a grown adult can survive on a monotonous diet does not sit well with me. I think this relies on some assumptions that haven't been well understood yet.
