In defining individual consumers and nonconsumers of
yogurt, the information reported in both 24-hour recalls and the
FFQ was considered. Individuals who reported yogurt intake
(natural or with fruits) greater than zero in at least 1 of the 24-
hour recalls and/or a frequency of intake different to zero in the
FFQ were considered consumers, whereas individuals who
reported yogurt intake equal to zero in both 24-hour recalls and
a frequency of zero in the FFQ were considered nonconsumers.
