A new century-long study of recipes published in the British edition of Good Housekeeping reveals a significant narrowing in the variety of seafood presented to readers. University of Exeter researcher Dr. Ruth Thurstan analyzed 1,192 fish and shellfish recipes published from 1923 to the present day to map changing culinary trends.

The Big Five Dominance: Modern seafood diets have condensed around cod, haddock, tuna, salmon, and shrimp, which now comprise approximately 80% of all seafood consumed in the United Kingdom.
Historical Recipe Shifts: Past decades featured a much more diverse array of species like herring, oysters, and lobster, demonstrating that the narrowing is driven by media and supply chains rather than a natural lack of availability.
Supply Chain Drivers: The shift reflects decades of interacting changes in trade, supply chains, and market availability that shaped what domestic cooks perceive as familiar and desirable.

The Context & Background

Published in the journal People and Nature, the research highlights how everyday culinary resources mirror our evolving relationship with food. Dr. Thurstan emphasizes that modern diets are not fixed or inevitable, but are shaped by historical, economic, and cultural factors.

Why it matters:Understanding how commercial supply chains and media narrow our culinary choices is vital for building healthier and more sustainable food systems. By recognizing that modern diets are flexible rather than fixed, policymakers and consumers can work toward diversifying seafood consumption and supporting marine conservation.
