Policymakers increasingly require scientific evidence on both health and economic consequences of different nutritional patterns. The aim of this study was to assess health and economic effects of Mediterranean and soy-containing diets. Selected countries were Belgium and the United Kingdom.
Cost-effectiveness of these plant-based food patterns was assessed in comparison with a "conventional" diet using an age- and sex-dependent prediction model. The model allowed the prediction of health outcomes and related health care costs for the food patterns over 20 y. A societal perspective was applied for cost calculation and health outcomes were expressed in quality-adjusted life-years (QALYs).
For Belgium, a soy-containing diet is estimated to lead to 202 QALYs and 107 QALYs per 1000 women and men, respectively, whereas societal savings of €2 146 000 and €1 653 000 are predicted. For the United Kingdom, a gain of 159 QALYs and 100 QALYs per 1000 women and men, respectively, is estimated, as are a prediction of savings of £1 580 000 and £1 606 000. For the Mediterranean diet in the corresponding estimates for Belgium are 184 QALYs and 148 QALYs per 1000 women and men, respectively, and savings of €1 618 000 and €1 595 000. For the United Kingdom, these are 122 QALYs and 110 QALYs per 1000 women and men, respectively, and savings of £1 155 000 and £1 046 000, respectively.
A wider implementation of plant-based eating would lead to large net economic gains for society and improved health outcomes for the population.
政策制定者越来越需要有关不同营养模式对健康和经济影响的科学证据。本研究旨在评估地中海和含大豆饮食的健康和经济影响。选定的国家是比利时和英国。
使用年龄和性别依赖的预测模型，将这些植物性食物模式与“常规”饮食进行成本效益评估。该模型允许对这些食物模式在 20 年内的健康结果和相关医疗保健成本进行预测。采用社会视角进行成本计算，并用质量调整生命年（QALY）来表示健康结果。
对于比利时，预计含大豆饮食可使 1000 名女性和男性分别获得 202 个 QALY 和 107 个 QALY，同时预计社会储蓄分别为 214.6 万欧元和 165.3 万欧元。对于英国，预计女性和男性分别获得 159 个 QALY 和 100 个 QALY，预计分别节省 158 万英镑和 160.6 万英镑。对于地中海饮食，在比利时的相应估计中，女性和男性分别获得 184 个 QALY 和 148 个 QALY，分别节省 161.8 万欧元和 159.5 万欧元。对于英国，这些分别是女性和男性的 122 个 QALY 和 110 个 QALY，分别节省 115.5 万英镑和 104.6 万英镑。
更广泛地实施植物性饮食将为社会带来巨大的净经济效益，并改善人口的健康结果。
