Every year around now a bowl of candy appears. In the office, on the kitchen counter, by the front door. For about a week it's everywhere and it's free.
I don't eat it. Not because of the sugar, but because of everything else in it. But I still feel the week: by Thursday I'm heavier and sleeping worse. So I looked into what's going on, and most of it has nothing to do with whether the candy is “clean”.
