Fish Oil Doesn’t Work? Anti-Aging Butterflies, the Ancient Brain Focus Switch, and the Best Brain Diet : 1491

Dave Asprey breaks down the latest biohacking research, questioning whether fish oil actually protects the brain, exploring anti-aging lessons from butterflies, uncovering an ancient brain mechanism that governs focus, and identifying the dietary patterns that best support long-term cognitive health. He examines recent evidence that challenges the long-held belief that fish oil is a no-brainer for brain protection, and instead presents a more nuanced picture of its efficacy. The episode also covers surprising findings from butterfly biology that could inform human longevity strategies, and practical tips for improving attention by tapping into the brain’s evolutionary built-in focus switch.
