Values are mean ± SE. CO2-eq, carbon dioxide equivalent; GHGE, greenhouse gas emissions; RAE, retinol activity equivalent.

2

Low-GHGE diets are defined as those in the lowest quintile of GHGE (kg CO2-eq/1000 kcal per day). High-GHGE diets are defined as those in the highest quintile of GHGE per 1000 kcal per day.

3

Determined by t test. Statistical tests were not run on the GHGE continuous variable (first 2 rows), because the quintile groups were based on it.
