How many of you made resolutions this year connected to your diet? It’s a time-honoured tradition shared by many. And though we don’t have the data, there’s a good chance more people than ever resolved this year to make their diet central to living longer and not just losing weight.
One of the nine food and beverage trends in our 2025 Nourish Trend Report was "I Wanna Live Forever: Eating for Longevity." Since the report's publication in November 2024, this trend has picked up remarkable speed, spurred by a surge of media interest and a groundswell of consumer curiosity. Apple TV's documentary "Longevity Hackers" and Netflix's "Don't Die: The Man Who Wants to Live Forever" have thrust the idea of living longer and better into the cultural mainstream.
The subject of the latter doc is Bryan Johnson, who is on a mission to show what's possible, offering himself up as a human guinea pig. You can access his Blueprint Protocol here and see what he eats in a day. Even if it isn't reputable science, it does bring attention to the concept of longevity and anti-aging, reinforcing the value of dietary interventions in reversing biological aging markers. Similarly, Peter Attia's book "Outlive" continues to climb bestseller lists, further evidence of the public's appetite for practical, science-backed longevity solutions.
Uncovering the Science of Living Longer AND Better
While the idea of significantly extending the human life span may remain speculative, the pursuit of a longer health span is a tangible goal that is captivating individuals and industries. Longevity is becoming a household word—some in the media say it’s replacing wellness as the new "it" word—and a growing field of rigorous scientific research, aided by the power of AI and wearables.
Despite recent criticisms of the foundational data behind Blue Zones (parts of the world where superannuated residents are the norm rather than the exception), due to errors in birth records, the concept and brand have proven resilient. Blue Zone tourism has become an industry with a focus on local cuisine, and according to Booking.com's travel prediction research for 2025, 54% of Canadian travellers surveyed were interested in a longevity retreat.
And while there has been some contention around the validity of Blue Zones, analysis led by Tufts Medical Center of Long Life Family Study (LLFS) participants, appears to back up some of the dietary recommendations. The LLFS enrolled approximately 5,000 individuals aged 18–110 years with family traits of extreme longevity to identify metabolic markers associated with aging, longevity, and mortality. Researchers analyzed 408 metabolites and discovered subsets associated with each category, further grouping them into 19 "signatures" to differentiate those associated with damage from those that were beneficial. These signatures revealed potential connections between diet and longevity, with an emphasis on plant-based foods rich in ergothioneine (mushrooms and asparagus), flavones (celery and parsley), and salsolinol (dark chocolate).
Strong social connections are also an important part of longevity and healthy aging. We know that people connect over food. How about starting a Sunday longevity supper club with friends? It’s a whole lot easier to keep a resolution if you’re not going it alone!
