I have to admit, I can’t take credit for this this list. I heard Dr. Mark Hyman mention that there are 257 different kinds of sugar on the Katie Couric show. After tracking down the reference, I learned that Jeremy Godwin of “Single Man’s Kitchen” https://www.facebook.com/notes/single-mans-kitchen/all-the-249-names-of-sugar-so-far-project/10150839799498198 is the genius behind this exhaustive list. Thanks Jeremy!
