Who is the patron saint of food?

There isn't one specific patron saint of food, but there are several saints associated with different aspects of food:

St. Anthony the Abbot is often considered the patron saint of food and drink due to his association with the poor and needy, who he often fed.

St. Isidore the Farmer is the patron saint of farmers and agricultural workers, thus indirectly associated with food production.

St. Martin de Porres is the patron saint of cooks, waiters, and others involved in the preparation and service of food.

St. Michael the Archangel is often invoked for protection of food and drink from spoilage.

St. Joseph is the patron saint of families, and thus indirectly associated with meals and gatherings.

Ultimately, the choice of patron saint for food depends on the specific aspect you want to emphasize.
