John West Revolution: Canned Tuna to Be Powered by Lab-Grown Fat by 2030
In the boldest shift in seafood history, John West has unveiled plans to replace traditional vegetable oils in their canned tuna with lab-grown fish fat—a move that could slash carbon emissions by 60% and make the world’s most popular protein fully sustainable within a decade. The company, partnering with a San Francisco biotech startup, will begin pilot production next year, aiming for grocery shelves by 2032. Critics warn the “franken-fat” could disrupt global fishing economies, but early taste tests report a buttery, melt-in-your-mouth texture that skeptics call “the future of lunch.”
