Abstract(s)
Eating behaviors and healthy food choices are associated with food literacy, and they have
a huge impact on one’s health status. For that reason, to increase food literacy is a way to effectively
help individuals make appropriate choices that help maintain health and diminish the incidence of
non-communicable diseases. The objective of this work was to test and validate a scale to assess
food literacy. The validation was conducted on a sample of 924 Portuguese university students. The
scale was composed of 50 items, which were submitted to exploratory and confirmatory factors
analysis. The final validated scale corresponded to a second-order model with a global factor called
“Food literacy”, which retained 26 items distributed by three factors: F1—literacy about the
nutritional composition of foods (10 items), F2—literacy about labelling and food choices (7 items),
and F3—literacy about healthy eating practices (9 items). The internal consistency of the scale is very
high, with an alpha higher than 0.9, and the Pierson correlations between the three factors and the
global are also higher than 0.9. In conclusion, the present scale has been validated and can therefore
be utilized to measure food literacy.
