Abstract

Background

In addition to the health effects of plant-based diets, their impact on the environment is becoming increasingly important. This study was conducted to assess the impact of adherence to a plant-based diet on sustainable eating behaviors.

Materials and methods

This cross-sectional study was conducted on 2122 Turkish adults, 73% female and 27% male. The plant-based diet index (PDI), healthy plant-based diet index (hPDI) and unhealthy plant-based diet index (uPDI) were obtained from a validated semi-quantitative food frequency questionnaire (FFQ). After the index scores were calculated, the sample was divided into tertiles for each index. The sustainable eating behaviors of the participants were determined with the ‘Behaviors Scale towards Sustainable Nutrition’.

Results

The PDI and hPDI levels of female participants were found to be higher than those of male participants. Factors such as age, exercise and educational status were also found to affect adherence to a plant-based diet. In regression models, PDI (Model 1; β: 0.413, Model 2; β: 0.369, Model 3; β: 0.367) and hPDI (Model 1; β: 0.462, Model 2; β: 0.366, Model 3; β: 0. 351) scores had a positive effect on sustainable eating behavior scores, whereas uPDI (Model 1; β: −0.496, Model 2; β: −0.471, Model 3; β: −0.459) scores had a negative effect (P < 0.001).

Conclusion

Our findings suggest that individuals with higher adherence to overall plant-based and healthy plant-based diets exhibit more sustainable eating behaviors. Promoting healthy plant-based diets presents a promising approach to advancing sustainable nutrition, and mitigating environmental challenges. © 2024 Society of Chemical Industry.

对地球友好的盘子：植物性饮食对土耳其成年人可持续饮食行为的影响。

背景：除了植物性饮食对健康的影响外，它们对环境的影响也变得越来越重要。这项研究是为了评估坚持植物性饮食对可持续饮食行为的影响。材料和方法：本横断面研究对2122名土耳其成年人进行了研究，其中73%为女性，27%为男性。植物性饮食指数（PDI）、健康植物性饮食指数（hPDI）和不健康植物性饮食指数（uPDI）通过半定量食物频率问卷（FFQ）获得。在计算出指标得分后，将每个指标的样本分成几位数。采用“可持续营养行为量表”对参与者的可持续饮食行为进行测定。结果：女性受试者的PDI和hPDI水平高于男性受试者。年龄、运动和教育状况等因素也会影响对植物性饮食的坚持。在回归模型中，PDI (Model 1；β: 0.413，模型2；β: 0.369，模型3；β: 0.367)和hPDI(模型1；β: 0.462，模型2；β: 0.366，模型3；β:0。351)评分对可持续饮食行为评分有正向影响，而uPDI(模型1；β: -0.496，模型2；β: -0.471，模型3；β: -0.459)得分有负面影响(P结论：我们的研究结果表明，坚持整体植物性饮食和健康植物性饮食的个体表现出更可持续的饮食行为。促进健康的植物性饮食是促进可持续营养和减轻环境挑战的一种有希望的方法。©2024化学工业学会。
