Abstract

Background: Poor diet quality contributes to morbidity and mortality and affects environmental sustainability. The EAT-Lancet reference diet offers a healthy and sustainable solution. This study aimed to estimate the association between diet cost and dietary quality, measured with an EAT-Lancet Index.

Methods: An EAT-Lancet index was adapted to assess adherence to this dietary pattern from 24-h recalls data from the 2012 and 2016 Mexican National Health and Nutrition Surveys (n = 14,242). Prices were obtained from the Consumer Price Index. We dichotomized cost at the median (into low- and high-cost) and compared the EAT-Lancet index scores. We also used multivariate linear regression models to explore the association between diet cost and diet quality.

Results: Individuals consuming a low-cost diet had a higher EAT-Lancet score than those consuming a high-cost diet (20.3 vs. 19.4 from a possible scale of 0 to 42; p < 0.001) due to a lower intake of beef and lamb, pork, poultry, dairy, and added sugars. We found that for each one-point increase in the EAT-Lancet score, there was an average decrease of MXN$0.4 in the diet cost (p < 0.001). This association was only significant among low- and middle-SES individuals.

Conclusions: Contrary to evidence from high-income countries, this study shows that in Mexico, adhering to the EAT-Lancet reference diet is associated with lower dietar costs, particularly in lower SES groups. These findings suggest the potential for broader implementation of healthier diets without increasing the financial burden.

遵守 EAT-Lancet 指数可降低墨西哥人的饮食成本。
背景:饮食质量差会导致发病率和死亡率,并影响环境的可持续发展。EAT-Lancet 参考膳食提供了一种健康且可持续的解决方案。本研究旨在通过 EAT-Lancet 指数估算饮食成本与饮食质量之间的关系:根据 2012 年和 2016 年墨西哥全国健康与营养调查(n = 14,242 人)中的 24 小时回忆数据,对 EAT-Lancet 指数进行了调整,以评估该饮食模式的坚持情况。价格来自消费者价格指数。我们按中位数对成本进行了二分(分为低成本和高成本),并比较了 EAT-Lancet 指数得分。我们还使用多元线性回归模型来探讨饮食成本与饮食质量之间的关系:结果:与高收入人群相比,低成本饮食人群的 EAT-Lancet 得分更高(从 0 到 42 的评分中,20.3 分对 19.4 分;p 结论:与高收入人群的证据相反,低成本饮食人群的 EAT-Lancet 得分更高(从 0 到 42 的评分中,20.3 分对 19.4 分;p与高收入国家的证据相反,本研究表明,在墨西哥,坚持 EAT-Lancet 参考饮食与较低的饮食成本有关,特别是在社会经济地位较低的群体中。这些研究结果表明,在不增加经济负担的情况下,有可能更广泛地实施更健康的饮食。

期刊介绍: Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
