Send us Fan Mail How dietary polyunsaturated fats, especially omega-6 from seed oils, influence inflammation & heart health. Topics Discussed: Polyunsaturated fatty acids (PUFAs): Omega-6 from seed oils like safflower and corn can convert to pro-inflammatory molecules, while omega-3s produce resolving ones; imbalance biases toward chronic inflammation. Inflammation regulation: Acute inflammati...

Send us Fan Mail Methods & challenges of establishing causal relationships in health research, emphasizing epidemiology, randomized trials, and genetic approaches.

Hierarchy of evidence critique: Rejects rigid pyramids fa...

Send us Fan Mail Integration of brain metabolism with neural signaling, highlighting how core metabolites regulate energy use and protect neurons. Topics Discussed: Brain energy efficiency: Brains are much more energy-efficient than computers for similar processing, relying on adaptive metabolic strategies evolved under energy scarcity. Metabolism vs. information processing: Core metabolites like...

Send us Fan Mail Mitochondrial fatty acid synthesis is a little-known but essential pathway that supports energy production and metabolic health. Summary: Dr. Sara Nowinski explains how mitochondria not only burn fuels to make ATP but also synthesize their own fatty acids inside the matrix; this conserved pathway produces lipoic acid (an essential enzyme cofactor) and longer-chain fats required fo...

Send us Fan Mail How internal states like hunger and hormones shape instinctive behaviors, particularly parental care Episode Summary: Dr. Johannes Kohl explains instinctive behaviors in mammals, emphasizing how states like hunger and hormonal cycles modulate actions such as parental care; they discuss hypothalamic circuits, hormone integration, and pregnancy-induced brain changes, highlighting th...

Send us Fan Mail How mitochondria travel between cells and how this hidden communication shapes metabolism, immunity, and even potential therapies.
