Britain is witnessing a remarkable resurgence in the popularity of tinned tuna, with sales increasing by nearly 18% over the last two years, translating to an additional 2.25 million kilograms sold. This trend is primarily driven by health-conscious TikTok users who are sharing creative and easy recipes featuring tuna, emphasizing its affordability and high protein content. Lee Bannerman, Tesco's tinned fish buyer, noted that the rise in sales is largely attributed to younger consumers who are discovering the versatility of tuna in meals like spicy tuna bowls and pasta bakes. Historically, tinned fish was a staple in British households but lost popularity after World War II with the advent of refrigeration. However, Bannerman suggests that we haven't seen such excitement around tinned fish in nearly a century. The trend is not isolated to the UK, as similar recipes have gained traction in the US as well. LDH (La Doria), which supplies Tesco with its tinned fish, highlighted that even high-end restaurants are now incorporating tuna into their menus, a shift that reflects changing culinary trends. This boom in demand follows a broader pattern of TikTok-driven food trends, similar to the recent surge in cottage cheese sales.
