Assessment of dietary intake
The 24-h recalls aimed to include all foods and beverages
consumed in the period between waking on the preceding
day and waking on the interview day. Interviews were
conducted by trained personnel using an in-house data
program (KBS v7.0) linked directly to a food composition database. This food composition database was based
on the Norwegian Food Composition Table from 2006
(13) and supplemented with additional food items from
reliable sources. Before starting the recall, the participant
was asked whether the previous day was normal with
regard to food and beverage intakes (yes/no). Seventythree percent of the days were considered normal. During
the recall, each eating or drinking occasion was defined
by the respondent as breakfast, lunch, dinner, supper, or
snack. For the present analyses, only eating occasions
defined as ‘dinner’ were included. All components of the
dinner meals were included, such as beverages, appetizers,
and desserts.
