About this episode
This episode explores the connection between neuroinflammation and mental health, particularly how chronic inflammation affects serotonin production and overall brain function.
There's more to mental health than pills, prescriptions, and counseling. In this episode, I dive deep into the often-overlooked connection between major depressive disorder and neuroinflammation. While many focus solely on serotonin as the "happiness chemical," I'll reveal how chronic inflammation can actually "steal" the raw materials your brain needs to produce it. We'll unpack the biochemistry of how pro-inflammatory cytokines create a "fork in the road" for tryptophan, shifting it away from serotonin and toward neurodegenerative molecules that impact your memory, focus, and sense of reward. Topics discussed: - Link between systemic inflammation and major depressive disorder - Why genetics matter - Inflammation hijacking - Understanding cytokines - Physical changes in your brain - Anti-inflammatory effects - Steps to identify and mitigate inflammation ---------- My Live Program for Coaches: The Functional Nutrition and Metabolism Specialization www.metabolismschool.com ---------- [Free] Metabolism School 101: The Video Series…
