Food buying habits of people who buy wine or beer: cross sectional study

The findings of this interesting investigation suggest that wine
drinking people adhere to a more healthy Mediterranean diet in contrast to
beer drinking. The authors found only two different drink-food patterns:
one for wine and one for beer. However, the methodology of the study does
not allow to test whether those people who bought the wine-food pattern at
one point in time were the same as those who bought the beer-food pattern
at another. Consequently, to arrive to their conclusion, a subjective
inquire about possible changes in the drink-food patterns over time should
be added to the cross-sectional method used in the study.
