The relative cost of healthy and sustainable diets is key for their adoption in different countries. Using a newly developed modelling tool that generates different diet baskets, we compared the costs of diets following the EAT-Lancet healthy reference diet, the Mexican dietary guidelines and locals' current food intake. On average, the cost of the EAT-Lancet healthy reference diet baskets was 21% lower than that of the Mexican dietary guidelines baskets, and 40% lower than that of the current intake baskets (29% lower if the comparison was isocaloric). Findings were similar over time (2011-2018) and by geographic region. The higher cost associated with the larger amount of fruits, vegetables, legumes and nuts in healthy and sustainable diets was surpassed by the savings associated with their lower amount of animal protein sources, sugar-sweetened beverages and discretionary foods. We conclude that transitioning to better diets in Mexico is possible without a higher expenditure on food.
健康且可持续饮食的相对成本是其在不同国家得以采用的关键因素。我们使用一种新开发的能生成不同饮食组合的建模工具，比较了遵循《柳叶刀》健康参考饮食、墨西哥饮食指南以及当地人当前食物摄入量的饮食成本。平均而言，《柳叶刀》健康参考饮食组合的成本比墨西哥饮食指南组合低21%，比当前摄入量组合低40%（若进行等热量比较则低29%）。随着时间推移（2011 - 2018年）以及不同地理区域，研究结果相似。健康且可持续饮食中水果、蔬菜、豆类和坚果含量较高所带来的较高成本，被动物蛋白来源、含糖饮料和自由支配食物含量较低所节省的成本所抵消。我们得出结论，在墨西哥转向更健康的饮食是可行的，且无需在食物上增加支出。
