Promoting a more balanced animal/plant dietary protein ratio by changing portion sizes or introducing new foods is a promising means to improve diet quality, but little is known about the willingness of individuals to adopt such changes. Our objective was to assess the willingness to adopt dietary changes by these means. In a French cross-sectional study in 2018 (n = 2055), we analyzed the association between the willingness to eat smaller or larger portions or to introduce non-consumed protein foods and the current dietary patterns of individuals and their socio-demographic characteristics. These modifications had previously been identified as improving the nutrient adequacy of diets. Participants were more willing to eat smaller portion sizes than to introduce new foods and to eat larger portion sizes. The willingness for any modification varied depending on the food groups concerned. Participants were also more willing to eat larger portions and less willing to eat smaller portions when they were the most frequent consumers of the foods concerned. Participants were more willing to eat a new food if it was consumed in large quantities by individuals with a similar dietary pattern. This study underlines the importance of accounting for individual food habits when issuing nutritional recommendations.
通过改变食物份量或引入新食物来促进更均衡的动植物膳食蛋白质比例是改善饮食质量的一种有前途的方法，但人们对个人愿意采取这些改变的意愿知之甚少。我们的目的是评估通过这些方法改变饮食的意愿。在 2018 年进行的一项法国横断面研究中（n=2055），我们分析了愿意食用较小或较大份量或引入未食用蛋白质食物与个人当前饮食模式及其社会人口特征之间的关系。这些修改先前已被确定为改善饮食的营养充足性。与引入新食物相比，参与者更愿意食用较小份量的食物，而不是引入新食物和食用较大份量的食物。任何修改的意愿取决于所涉及的食物组。当参与者是所涉及食物的最频繁消费者时，他们也更愿意食用较大份量的食物，而不太愿意食用较小份量的食物。如果个人具有相似的饮食模式，参与者更愿意食用新食物。这项研究强调了在提出营养建议时考虑个人饮食习惯的重要性。
