formulaThe Core Sustainable and Healthy Diet Index (SHDI) score is calculated by summing the scores for all food groups categorized as "adequate intake."

claimThe Sustainable and Healthy Diet Index (SHDI) scoring methodology was inspired by previously published diet quality indices but does not follow any single index exclusively due to data compatibility issues.

procedureThe Sustainable and Healthy Diet Index (SHDI) scoring for "adequate intake" food groups uses four scenarios: (1) intake below the recommended minimum, (2) intake between the minimum and target recommendation, (3) intake between the target and maximum recommendation, and (4) intake above the maximum recommendation.

procedureThe researchers conducted linear regression analyses to examine the association between socioeconomic variables and total SHDI scores within each Case Study Territory (CST), using a model where the individual's total SHDI score is predicted by gender, age, education, and adjusted household income.

claimThe Sustainable Healthy Diet Index (SHDI) does not encompass all dimensions of sustainability; it excludes the economic pillar (such as food affordability or security) and represents the social pillar only through health-related aspects like dietary composition.

referenceThe study titled 'Sustainable and healthy diet index (SHDI) unveils regional differences in Europe and Northern Africa: findings from the SysOrg study' was published in the European Journal of Nutrition, volume 64, issue 275, in 2025.

claimThe Sustainable and Healthy Diet Index (SHDI) utilizes a food frequency questionnaire consisting of 24 food groups, which is designed to be economically feasible and applicable to various thematic surveys.

claimThe Sustainable and Healthy Diet Index (SHDI) excludes food groups such as dried fruits, refined grains, butter, margarine, and cooking oils because they were not part of the Planetary Health Diet (PHD) recommendations or contributed minimally to overall dietary impact.

claimThe Sustainable Healthy Diet Index (SHDI) is a tool developed to assess healthy and sustainable diets based on the Planetary Health Diet (PHD) recommendations.

claimHigher income was associated with a higher total SHDI in the Warsaw Case Study Territory (CST), while lower income was associated with a higher SHDI in the Cilento Case Study Territory (CST).

measurementThe Sustainable Healthy Diet Index (SHDI) study involved 2,210 respondents across five case study territories: Cilento (Italy), Copenhagen (Denmark), North Hessia (Germany), Kenitra (Morocco), and Warsaw (Poland).

claimThe Sustainable and Healthy Diet Index (SHDI) calculates scores for food groups categorized as "adequate intake" by assuming any intake has a health impact, where intake within the recommended range is beneficial and intake outside that range is potentially detrimental.

claimThe Sustainable and Healthy Diet Index (SHDI) estimates environmental and health impacts based on food group intake levels rather than direct measurement.

procedureThe Sustainable Healthy Diet Index (SHDI) methodology involves converting reported consumption frequencies for 24 food groups into grams to assess compliance with Planetary Health Diet (PHD) recommendations.

claimThe Sustainable and Healthy Diet Index (SHDI) does not directly measure health or environmental outcomes but estimates them based on food group intake patterns using Planetary Health Diet (PHD) recommendations as proxies.

claimDiet quality, as measured by total SHDI, increased with age in the study population.

procedureIn the SysOrg survey, researchers calculated the Sustainable Healthy Diet Index (SHDI) using the cooked weight of portions for legumes, which were assumed to be ready-to-eat (soaked and cooked).

claimRespondents from Copenhagen presented the diet closest to the Planetary Health Diet (PHD) based on Core SHDI scores, while the highest total SHDI scores were observed in Copenhagen and Warsaw.

measurementThe Sustainable and Healthy Diet Index (SHDI) score ranges from 0 to 120, with up to 54 points deducted for high intake of 'limit' food groups.

claimThe Sustainable and Healthy Diet Index (SHDI) subtracts points from the total score for six food groups classified as "limited intake" based on reported intake frequency, as frequent consumption of these groups is considered harmful to health.

claimThe SysOrg survey results may be subject to self-selection bias, as individuals with higher nutritional awareness or a stronger interest in health-related topics may have been more likely to participate, potentially skewing the Sustainable Healthy Diet Index (SHDI) scores upward.

claimThe Sustainable and Healthy Diet Index (SHDI) classifies dietary quality across different populations by using the Planetary Health Diet (PHD) as a globally applicable reference diet.

claimThe authors of the study 'Sustainable and healthy diet index (SHDI) unveils regional differences in Europe and Northern Africa: findings from the SysOrg study' have no relevant financial or non-financial interests to disclose.

claimThe Planetary Health Diet (PHD) was chosen as a benchmark for the Sustainable and Healthy Diet Index (SHDI) because it provides a globally applicable reference point, unlike local food-based dietary guidelines (FBDGs) or traditional diets like the Mediterranean diet, which are not uniformly applicable across all case study territories.

claimThe Sustainable and Healthy Diet Index (SHDI) covers several domains of sustainable and healthy diets but requires complementary studies on social and economic domains to be fully effective.

claimIn the North Hessia Case Study Territory (CST), males had a higher total SHDI compared to females, whereas in the Cilento and Warsaw Case Study Territories (CSTs), females had healthier diets.

claimA higher Sustainable and Healthy Diet Index (SHDI) score indicates a more sustainable and healthier diet.

measurementIn the study of five case study territories, Copenhagen and Warsaw exhibited the highest Sustainable Healthy Diet Index (SHDI) scores, indicating better adherence to the Planetary Health Diet.

claimThe Sustainable and Healthy Diet Index (SHDI) is a tool used to score region-specific dietary trends based on a food-group frequency questionnaire.

claimThe Sustainable and Healthy Diet Index (SHDI) provides an indication of the dietary impact on both health and the environment, though it lacks certain social and economic dimensions such as wellbeing, accessibility, and affordability.
