"we have a pretty poor understanding of how various foods interact with the human body" That's a fascinating area all by itself. I read a couple of years ago about a study in hyperactivity and (while it's not classic double-blind, etc) the anecdotal examples presented were interesting. In one case, a woman with identical twins (who were hyperactive and very unruly) started feeding one on "real food" rather than the processed stuff that many busy parents rely on. Two weeks later, there was a huge difference in behaviour, in the way that you might predict. I'll see if I can dig out a link. A friend of mine is a school-teacher, in a really rough school. They just banned all forms of soft drink, and he says that has, in itself, made a big difference with discipline. Basically, kids who were getting tanked up on sugar and "bouncing off the walls" are now noticeably calmer and easier to manage. Religious debates to one side, it's easy to forget that our bodies are just a bunch of chemicals, so the chemicals we put in are bound to make a difference. Thanks for relating your experiences :)
