A Scoping Review of Indicators for Sustainable Healthy Diets frontiersin.org Jan 12, 2022 8 facts
claimEnvironmental indicators for diets are not always positively correlated, meaning that dietary changes that improve one indicator, such as greenhouse gas emissions, do not guarantee improvements in other indicators, such as water use.
measurementWater use was the second most frequently assessed environmental concept of diets, accounting for 47 instances or 18% of all environmental indicators.
claimWater scarcity footprint is a preferred indicator for some researchers because it accounts for the varying impacts of water use based on the specific region, as cited by Hess et al. (2015), De Laurentiis et al. (2019), and Ridoutt et al. (2019).
measurementIn a scoping review of indicators for sustainable healthy diets, water use was the second most frequently measured environmental indicator, appearing in 47 instances.
claimGreenhouse gas emissions (GHGE) alone are considered insufficient to capture total environmental impact because other indicators, such as biodiversity loss and water use, represent important environmental impacts that must be accounted for.
claimResearch on the environmental effects of diets has primarily focused on greenhouse gases, land use, and water use, though measures for eutrophication, acidification, nitrogen and phosphorus use, and biodiversity are also utilized.
claimFrequently used indicators of water use in sustainable diet assessments include total water use, water footprint, blue water use, blue water footprint, green water use, green water footprint, freshwater use, and water scarcity footprint.
claimWater use as an environmental indicator quantifies the amount of water used to produce various goods and services.
How do the indices based on the EAT-Lancet recommendations ... medrxiv.org May 14, 2024 6 facts
claimThe Agribalyse v.3.1.1 database contains incomplete water use inventory data, necessitating the consideration of spatial and temporal variability.
measurementThe Agribalyse 3.1.1 database utilizes 14 specific metrics to assess environmental impact: greenhouse gas emissions (kg CO2 eq), exposure ionizing radiation (kg U235 eq), photochemical ozone formation (kg NMVOC eq), ozone depletion (Freon-11), emission of particulate matter (mortality due to particulate matter emissions), acidification (mol H+ eq), terrestrial eutrophication (mol N eq), freshwater eutrophication (kg P eq), marine eutrophication (kg N eq), freshwater ecotoxicity (CTUe), water use (m3 world eq), land use (loss of soil organic matter content in kg carbon deficit), fossils resource use (MJ), and metals and minerals resource use (kg Sb eq).
claimThe ELD-I index showed negative trends with a strong effect on freshwater eutrophication and moderate effects on GHGE, particulate matter emissions, acidification, and freshwater ecotoxicity, while demonstrating a positive relationship with water usage.
measurementThe indices based on EAT-Lancet recommendations are generally negatively correlated with the Product Environmental Footprint (PEF) and 14 individual environmental metrics (highest ρ = −0.33), except for water use and photochemical ozone formation, which showed positive correlations for the WISH and ELI indices.
measurementHigher scores on dietary indices were associated with higher nutritional quality and lower environmental impact, but were associated with unfavourable results for zinc intake, vitamin B12, and water use.
claimDietary patterns based on EAT-Lancet recommendations may lead to increased water use, which must be considered at national or subnational levels due to existing water stress in many countries.
Measurement of diets that are healthy, environmentally sustainable ... frontiersin.org 4 facts
measurementAmong the 132 environment-related outcomes analyzed in the 42 reviewed papers, the most frequent categories were climate change (33.3%), land use (15.2%), and water use (13.6%).
claimEnvironmental indicators that have existed the longest in the literature and have been the most frequently analyzed are climate-related outcomes, specifically GHG emissions (33.3%), land use (15.2%), and water use (13.6%).
referenceAleksandrowicz et al. (2016) conducted a systematic review on the impacts of dietary change on greenhouse gas emissions, land use, water use, and health.
claimShifting dietary patterns involves tradeoffs between policy goals, such as a shift to plant-based foods reducing greenhouse gas emissions while potentially resulting in higher water usage.
