| Description: |
Background Dietary patterns that limit or avoid animal products contribute fewer greenhouse gases and require less energy than diets containing more animal products. However, quantifications of these outcomes on a vegan diet in real-life conditions still need to be explored. Methods In a randomised controlled trial, a low-fat vegan diet supplemented with soybeans led to a significant reduction in hot flashes in postmenopausal women. In this secondary analysis of that study, we hypothesised that the intervention diet would have a reduced environmental impact, greenhouse gas emissions (GHGEs) and cumulative energy demand (CED). 3-day diet records were analysed at baseline and at the end of the 12-week study, and we linked dietary intakes to environmental footprints. Results Compared with no change in the omnivorous control group, we found that the vegan group had a decrease in GHGEs (p |
