Food purchase behaviour in a Finnish population: patterns, carbon footprints and expenditures.

ABSTRACT:

Objective

To identify food purchase patterns and to assess their carbon footprint and expenditure.

Design

Cross-sectional.

Setting

Purchase patterns were identified by factor analysis from the annual purchases of 3435 product groups. The associations between purchase patterns and the total purchases' carbon footprints (based on life-cycle assessment) and expenditure were analysed using linear regression and adjusted for nutritional energy content of the purchases.

Results
