This article seems well researched but I do question it’s validity. I have no access to a real computer right now so looking into the studies it references isn’t a real possibility but I do wonder what the effects on things like soylent where the addition of vitamins is extremely common. I know that several popular recipes use additional vitamins to make them nutritionally complete.
These were just the first three recipes I saw, so maybe all recipes use additional vitamins? I know the recipe I’m currently concocting does. I don’t know how much of this article is based on reality or how valid the studies it referenced were but if they are indeed studies that carry weight it seems they are something we should be taking seriously.
