Overview
Brief Summary
Two randomized control trials examining human food choice (i.e. selection of high energy 'unhealthy' foods vs. selection of healthier foods). Interventions: In a between-subjects design, participants (recruitment stratified by socioeconomic position) made food choices (main dish, plus optional sides and desserts) in the absence vs. presence of menu energy labelling and from menus with baseline (10%) vs. increased availability (50%) of lower energy main dishes. Main outcome measures: Average energy content (kcal) of main dish chosen and average total energy content of all food ordered, including optional sides and desserts.
