For nearly a century, scientists believed we had discovered ALL of the essential fatty acids the human body needs. But what if they were wrong?

Stephanie Venn-Watson, a veterinary epidemiologist and longevity researcher, joins Dave to reveal a groundbreaking discovery—a newly identified essential fatty acid, C15, that may hold the key to healthier aging and even longer lifespans. Originally uncovered in an unlikely place—U.S. Navy dolphins that were outliving their wild counterparts by decades—this forgotten fat is now shaking up the scientific community.

So why hasn’t anyone told you about it?? Decades of misguided dietary advice stripped this crucial nutrient from our food system, leaving an entire generation unknowingly deficient. Even worse, pregnant women have been some of the MOST hurt from this cruel change to our modern diet. Now, cutting-edge research is proving that C15 plays a critical role in cellular stability, mitochondrial function, and total mental health.

What You’ll Learn in This Episode:

• The first new essential fatty acid discovered in nearly 100 years—and why it matters

• How dolphins led to one of the BIGGEST breakthroughs in human nutrition

• Why the removal of C15 from our diets is accelerating aging

• The surprising connection between C15 and mental health

• How this “missing” fat could outperform some of the biggest longevity drugs today!

• What foods naturally contain C15—and should you supplement it?
