Diet quality index (DQI) diversity score (DDS). GHGEs 3.21 ± 2.07 kg CO2-eq/person/day total WF 2832 1378 L/person/day. DQI DDS 62.26 8.28 6.66 1.31, respectively. Total energy significantly higher highest tertiles (2238 722 2383 701 kcal, respectively) compared lower tertiles. Individuals diet-related had a daily nutrients exception percentages supplied carbohydrates, meeting according recommended allowance (RDA), (excluding total, moderation, overall balance score), scores (p < 0.001). value are than world average. results would help develop guidelines encourage sustainable choices.
