Suffering from rheumatism since his youth, Gaudí turned to natural medicine and the teachings of German physician Sebastian Kneipp. By the age of 40, he had fully embraced a vegetarian lifestyle, believing that a simple diet without meat or fish kept his mind sharp for his artistic endeavors.

His daily meals typically consisted of raw lettuce or endive with olive oil, nuts such as hazelnuts and almonds, and fresh fruit. He avoided heavy seasonings like salt, often opting for a light lunch of crushed vegetables mixed with milk and water.

This disciplined approach to nutrition was a core part of the routine for the creator of the Sagrada Família, blending physical health needs with his unique artistic and spiritual vision.
