I realize that I am occasionally a luddite about things, but bearing in mind the corn lobby, the packaged food lobby, and the fact that Splenda was pushed through FDA trials quickly because people were so excited about the latest magic no-sugar pill, it makes me concerned. I don't think that we truly understand the intricacies of nutrition as a science yet. We're still figuring out that some amino acids are important but only in combo with others, etc. In that case, an engineered solution is not only usually based on profit motive, but also on incomplete data. That's not good engineering in my book.
