Are Climate-friendly Diets Healthier? A Method to Estimate the Correlation Between Nutritional Quality and Carbon Footprints of Usual Diets (OR20-02-19)

摘要

ObjectivesRecent research indicates that climate-friendly diets are healthier, but much of this evidence is based on aggregate consumption data or on individuals' dietary intake data from just one observation day. Analysis of individuals' self-selected diets is important for applying dietary guidance, but usual intake over time is needed to better assess relationships with human health and environmental outcomes. To address this gap, we developed a method to estimate the association of dietary carbon footprints with nutritional quality for usual intake based on multiple observation days.
