In this paper I focus on the dietetic discussion at the end of the Timaeus (86b–90d) and read it against the background of the medical dietetics of its day. I try to show that Plato’s version of dietetics is deeply rooted in the preceding medical tradition and that it draws in particular on ideas attested in the Hippocratic treatises On Regimen and Airs, Waters, Places. On the other hand, I also argue that Plato is most likely the first author ever to identify intellectuals as a specific dietetic category and to propose a preventive regimen adapted to the specific needs of mathematicians, philosophers, and other men of letters. Therefore, his dietetic discussion in the Timaeus deserves recognition as an important contribution to the history of dietetic therapy and prevention.

在本文中，我重点关注《蒂迈欧篇》（86b-90d）末尾的饮食讨论，并在当时的医学饮食学背景下阅读它。我试图表明，柏拉图的饮食学版本深深植根于先前的医学传统，并且它特别借鉴了希波克拉底论文《养生法》和《空气、水、地点》中所证明的思想。另一方面，我还认为，柏拉图很可能是第一个将知识分子视为特定饮食类别并提出适合数学家、哲学家和其他文学家特定需求的预防方案的作者。因此，他在《蒂迈欧篇》中关于饮食的讨论值得被认可，被视为对饮食治疗和预防历史的重要贡献。
