The article from El País discusses the rising trend of using canned sardines for quick and easy meal preparations, particularly for appetizers, salads, and pasta dishes. It emphasizes how canned sardines have become fashionable on social media, encouraging individuals to explore their culinary potential rather than letting these items languish in the pantry. Suggestions include making sardine pasta and pâté for snacks with toasted bread, showcasing their versatility.

However, the article also warns about certain viral videos that take this trend to extremes, such as dramatic methods of preparing canned sardines that could lead to safety issues, like burning paper while smoking them indoors. These demonstrations often overshadow the simplicity and convenience that should be inherent in utilizing canned sardines as a staple pantry item.

Additionally, the article critiques the restrictive diets trending on social media that advocate eating sardines exclusively three days a week, suggesting that while this may appeal to cat lovers, it could be detrimental to one's health. Furthermore, it addresses the common practice of overwhelming the flavor of the sardines with excessive ingredients, urging readers to appreciate and highlight the fish’s natural taste instead.
