UK Seafood Diets Narrowed Significantly Over Past Century, Study Finds
A century-long analysis of recipes shows a dramatic shift from diverse seafood dishes to a reliance on just five species, largely imported.
British seafood consumption has dramatically narrowed over the last century, with a preference for just five species—cod, haddock, tuna, salmon, and prawns—now accounting for about 80% of all fish eaten in the UK. This shift has led to a significant increase in imported seafood, as these commonly consumed fish are often not caught domestically. The findings are based on a study analyzing nearly 1,200 recipes from the British edition of Good Housekeeping magazine, spanning from 1923 to the present day.
Researchers noted a stark contrast between historical and modern recipe trends. Prior to the 1970s, recipes featured a wide variety of fish, including less common options like lobster, oysters, and herring. Dishes such as oyster soup, jellied herrings, and fish baked in custard were more prevalent, reflecting a broader culinary landscape and an emphasis on utilizing available domestic resources, even during periods like World War II rationing when alternative proteins were scarce.
A Shift in Culinary Tastes
The transition towards a limited range of fish species became pronounced after the 1970s. This period coincided with a decline in UK fish stocks due to overfishing, leading to stricter regulations. Simultaneously, the rise of supermarkets, frozen foods, and standardized products influenced consumer choices and what was presented in recipe publications. By the 1980s, the 'big five' species dominated magazine recipes, while the diversity of other fish decreased.
Dr. Ruth Thurstan, the lead author of the study from the University of Exeter, stated that this change reflects not just a narrowing of available species but a deliberate focus in publications on what readers were being shown and encouraged to cook. The trend also shifted recipes to be more aspirational, featuring dishes like Gochujang sticky cod and miso prawn skewers. The study, published in People and Nature, suggests this evolution was driven by interconnected changes in fish supply, trade, and distribution networks, which ultimately shaped domestic cooks' perceptions of familiar and desirable seafood.
While the recipes offer insight into culinary trends rather than direct consumption figures, they illustrate a significant departure from Britain's historical relationship with its marine resources. The reliance on imported fish has grown substantially, with the UK importing over six times more seafood in 1985 than in 1900, and fish traveling an average of over 2,000 miles to reach British tables.
