Using data from the Multipurpose Survey of Daily Life by ISTAT, we analyse the profiling and social stratification of eating styles among Italian adults from 1997 to 2016. We apply Latent Class Analysis on a set of common foods to document the existence of six consumption clusters, (herbivore, carnivore, hedonist, enhanced Mediterranean, paucivore, omnivore) and their relative size over time. We then illustrate how gender and education are associated with each of the identified clusters and document the evolution of their gradients over time.

Results point to an increase in the relative size of the herbivores and omnivores, a substantial stability of the hedonists and paucivores, and a decline of the carnivores and enhanced Mediterraneans. Moreover, our findings highlight a substantial social stratification of eating profiles and show that, within a broad picture of persistence, gender and education became more important in affecting the propensity of adopting certain profiles.

使用来自 ISTAT 日常生活多用途调查的数据，我们分析了 1997 年至 2016 年意大利成年人饮食方式的特征和社会分层。我们对一组常见食物应用潜在类别分析，以记录六个消费集群的存在， （草食动物、肉食动物、享乐主义者、增强型地中海动物、食肉动物、杂食动物）及其随时间变化的相对大小。然后我们说明性别和教育如何与每个识别的集群相关联，并记录它们的梯度随时间的演变。

结果表明食草动物和杂食动物的相对体型增加，享乐主义者和食肉动物的基本稳定，以及食肉动物的减少和地中海地区的增强。此外，我们的研究结果突出了饮食特征的实质性社会分层，并表明，在持久性的广泛情况下，性别和教育在影响采用某些特征的倾向方面变得更加重要。
