A comparison of commonly used diet quality indexes (DQIs) and their association with multiple indicators sustainability has not been performed, which limits policy action. To evaluate the associations between 8 DQIs 7 in a nationally representative sample United States. In this cross-sectional analysis, dietary data from National Health Nutrition Examination Survey (2011-2018, n = 18,522 ≥20 y) were merged on greenhouse gas emissions (GHGE), cumulative energy demand (CED), water scarcity footprint (WSF), land, fertilizer nutrients, pesticides, food prices publicly available databases. Diet was measured using Healthy Eating Index-2020 (HEI-2020), Alternate Index-2010 (aHEI-2010), Mediterranean Score (Med), (aMed), Healthful Plant-Based Index (hPDI), Planetary (PHDI) for States, Dietary Approaches to Stop Hypertension (DASH), Nutrient-Rich Foods 9.3 (NRF9.3). The relationship each DQI indicator assessed linear regression. Greater scores most or all associated lower daily per capita GHGE (β -0.908 -0.250 carbon dioxide equivalents 1 unit increment z-score), CED -2.699 0.202 MJ), land -0.002 <-0.001 ha), nutrients (β= -0.026 0.007 kg).

The future of plant-based diets is a complex public health issue inextricably linked to planetary health. Shifting the world's population consume nutrient-rich, among most impactful strategies transition sustainable food systems feed 10 billion people by 2050. This review summarizes how international expert bodies define and describes types dietary patterns. It also explores type proportion plant- versus animal-source foods alternative proteins relate reduce diet-related morbidity mortality. Thereafter, we synthesize evidence for current challenges actions needed achieve patterns using conceptual framework with principles promote human health, ecological social equity, economic prosperity. We recommend governments, businesses, civil society encourage marketplace choices that lead plant-rich within healthy, equitable, resilient agroecological systems.

Social risk assessments and case studies of labour conditions in food production primarily focus on specific subpopulations, regions commodities. To date, research has not systematically assessed against international standards across diverse, complex products. Here we combine data production, trade, intensity qualitative coding to quantitatively assess the forced embedded US land-based supply, building our previous assessment fruits vegetables. We demonstrate that animal-based proteins, processed vegetables, discretionary foods are major contributors 62% total stems from domestic or processing. Our findings reveal widespread present supply necessity collaborative action all countries-high, middle low income-to eliminate reliance exploitation.

Improving diet quality while simultaneously maintaining planetary health is of critical interest globally. Despite the shared motivation, advancement remains slow and research community continues to operate in silos, focusing on certain pairings (diet-climate), or with a discipline-specific lens, sustainable diet, rather than examining their totality.

In recent years, numerous examples of food system dashboards have been developed with the goal offering users opportunity to monitor or assess (their) national systems. One many challenges faced by these initiatives has strike an acceptable balance between complexity, local-specificity, and multi-sectoral nature systems while also ensuring that information remains accessible usable for decision-makers. Perhaps even more critical, yet rarely discussed implemented in most current dashboard initiatives, is imperative co-constructing local stakeholders. The case presented this study puts participation at center design construction a systems’ monitoring dashboard.

Reducing the environmental pressures stemming from food production is central to meeting global sustainability targets. Shifting diets represents one lever for improving system sustainability, and identifying sustainable diet opportunities requires computational models represent complex systems allow users evaluate counterfactual scenarios. Despite an increase in number of models, there remains a lack transparency data inputs mathematical formulas facilitate replication by researchers application diverse stakeholders. Further, many ability model multiple geographic scales. The present study introduces Foodprint 2.0, which fills both gaps. 2.0 updated biophysical simulation that estimates agricultural resource requirements patterns can be adapted suit variety research purposes. objectives this are to: 1) describe new features 2) demonstrate performance estimating demand United States (US) using nationally representative dietary National Health Nutrition Examination Survey 2009–2018.
