Abstract
Conclusions: Using life-sized food photographs among adolescent Mozambican girls resulted in a rather large variation in the accuracy of individuals' estimates. The ability to rank individuals according to their consumption was, however, satisfactory for most foods. There seems to be a need to further develop and test food photographs used in different populations in Sub-Saharan Africa to improve the accuracy of portion size estimates.
