Eproducibility of a FG-QFFQ; the very first assessed a single week of food intake (7-day FG-QFFQ), as well as the second covered 1 month (30-day FG-QFFQ). two. Components and Solutions two.1. Study Participants This cross-sectional study was conducted in 2010011 in Porto Alegre city, southern Brazil, which includes 155 males and women.
