Environmental Database

Welcome to the NHS Environmental Database!

Unlike many other files on this website, the environmental database does not provide nutrient data. This database includes four environmental impact metrics – greenhouse gas (GHG) emissions, irrigation water use, nitrogen use, and high-quality cropland use – for the 156 food items listed in the food frequency questionnaire (FFQ) of the 2011 Nurses’ Health Study II.

For our recent publication in the Lancet Planetary Health – “Health and environmental impacts of plant-rich dietary patterns: A U.S. prospective cohort study” (2022) by Musicus et. al. – this database was leveraged to characterize the environmental impacts, as compared to the health impacts, of four dietary patterns within a longitudinal U.S. cohort.


PLEASE NOTE: We do not have the capacity to answer questions about the data provided. The datasets include thorough documentation.
