Diet Quality and Environmental Sustainability Are Linked But in Unexpected Ways

摘要

Studies linking diet quality with environmental impacts in the US have generally not accounted for the additional burden associated with retail losses, inedible portions, and consumer waste. Moreover, there is a need to assess the environmental impacts of shifts in diet quality using data collected directly from individuals, rather than assessing the impacts of nutritionally perfect theoretical diets. This study fills these important research gaps by assessing the relationship between observed diet quality among a nationally-representative sample and the amount of agricultural resources used to produce food.
