The 2007-2008 dietary supplement use 30-day files have been updated and given new, descriptive names. The new files still include all variables in past cycles, and include 33 new nutrients/dietary component variables. Analysts are encouraged to read the documentation in order to understand the new names and structure of the files as well as the new variables. Past release cycles will be re-released in the future with the same updates as the 2007-2008.
