Discorsi della vita sobria (Discourses on the Sober Life)
The Discorsi della vita sobria is Cornaro’s first-person account of the spare diet he adopted after a health crisis in his fortieth year and credited with his recovery and long life. It is the founding text of the dietary-restriction-for-longevity tradition and the primary source for the case. The work is structured as successive discourses written, by Cornaro’s account, at advanced ages, each restating and extending the argument that strict moderation in food and drink is the means of preserving health and prolonging life. As evidence it is a single self-reported life history rather than a controlled demonstration: there is no comparison group, no measured endpoint beyond Cornaro’s own claimed lifespan, and the lifespan figure itself is uncertain because Cornaro overstated his age. The text is cited here for the regimen and the claim as Cornaro stated them, not as a verified outcome.
