8O8 (sorry, I don’t know your name), there are issues with practically everything. Everything we intake has a level of toxicity, including dihydrogen oxide, nitrogen, carbon dioxide, etc. And we are not just cooking a simple little pudding here! Many of the ingredients in use by DIY soylenters, ingredients on your list, are quite toxic at certain levels, sometimes at levels not all that far above those recommended. The same things that are essential for growth, metabolism, health and reproduction are also toxic – and human nutrition is still far from being an exact science.
I may as well state here and now that I am starting to feel some foreboding for the growing enthusiasm for soylent experimentation. Personally, although at first I was attracted to the idea of a presumed potential health boost through the ingestion of a carefully compounded balanced diet of pure nutrients, listening to folks’ actual experience with those pure nutrients here has led me to believe that much of what’s going on is potentially dangerous. Personally I have adopted another approach, which if I can ever get time I think I need to post here in detail – an approach to soylent which utilises only “real food” ingredients (with apologies to Rob for what he will call my “essentialism”). The body is a robust system, as Rob frequently points out, a system which has undergone millennia of natural selection for survival on widely varying diet; it is extremely tolerant when it comes to foods. It may prove less tolerant of pure nutrients; the anecdotal evidence here certainly suggests that. Quite a few experimenters are experiencing bellyaches, headaches, malaise, diarrhoea, and other such symptoms suggesting low tolerance for some of what’s being ingested.
I’m not saying people shouldn’t experiment. How else can we learn what we need to know? But I think a certain amount of respect for the seriousness of our task is required, plus pooling of our knowledge and sustained investigation of unresolved issues such as the phytic acid question. It is not good just to blow off an issue of that kind. Something that you just run right over may well jump up and bite you in the butt as you pass!
