Author’s response to reviews Title: Food purchase patterns: empirical identification and analysis of their association with diet quality, socio-economic factors, and attitudes Authors:

I believe you need to explain more about the food grouping. I cannot quite grasp the construction of the groups, not even by looking in your ref 20. For example how come juice is grouped with vegetables/salad? What is the connection between brown bread and potatoes? Eggs together with sausages and cream? And the subgroups in Fats and oils why section vegetable oils in several subgroups, and what is the difference between these (all vegetable) oils and 'vegetable fat' in the Lard, vegetable fat group? Oilseed is to the best of my knowledge an umbrella term for several different crops used to produce oils.
