I have been very intrigued by Soylent and have wanted to try it. However, I could never drink a standard recipe because I have PKU, which requires a low phenylalanine diet (Phenylalanine is an amino acid found in most proteins). That means any recipe that calls for Whey Protein will not work. Even Masa flour would introduce too much protein (I limit myself to a little less than 10g of normal, phenylalanine-rich protein a day).
However, I have been working on a recipe on the DIY site. The main protein source is a powder called MTE Amino Acid Blend which is a prescription powder for people with PKU. It has the other essential amino acids, but does not contain Phenylalanine.
I would love to get some feedback on anything I am missing or problem areas the Soylent community sees with my formula:
