Women's Hormones and Alzheimer's Risk: New Understanding of Brain Health in Menopause

Peter Attia interviews neuroscientist Lisa Mosconi about how hormonal transitions in women affect Alzheimer's disease risk and brain health. The discussion covers the emerging ability to detect preclinical Alzheimer's disease through biomarkers and imaging before cognitive symptoms appear, which can last for decades.

Seed Oils vs. Lard: What the Science Actually Shows

Layne Norton and Peter Attia dive deep into the lipid science comparing seed oils and lard for cooking, concluding that both ultra-processed fried foods are unhealthy regardless of oil type, and that marketing either as 'healthy' is misleading. The discussion emphasizes the importance of reading actual studies rather than social media interpretations.

Women's Alzheimer's Prevention: Lifestyle, Menopause, and Emerging Treatments

Lisa Mosconi discusses sex-specific Alzheimer's prevention strategies for midlife women, emphasizing behavioral interventions (exercise, sleep, nutrition, stress management) as the primary prevention tools while highlighting emerging pharmaceutical options like GLP-1 agonists and klotho. The conversation stresses that consistent lifestyle adherence over years—not quick fixes—builds cognitive resilience, and that hormone replacement therapy warrants serious consideration during menopause pending further research.

Why Women Develop Alzheimer's Earlier: Brain Changes Begin in Midlife

Lisa Mosconi, a neuroscientist studying sex differences in Alzheimer's disease, argues that women show earlier pathological brain changes in midlife compared to men, and that the 2:1 female-to-male prevalence cannot be explained by longevity differences alone. The disease is fundamentally a midlife condition with late-life symptoms, requiring investigation into what biological factors differ between men and women during midlife.

Seed Oils and Longevity: Evidence-Based Analysis of Nutritional Harm Claims

Peter Attia and Lane Norton examine whether seed oils pose unique health risks compared to other dietary fats, using a structured 'steelman' approach where Attia presents the strongest case against seed oils while Norton defends the evidence suggesting they are not uniquely harmful. The discussion emphasizes examining converging lines of evidence, acknowledging personal biases, and distinguishing between anecdotal claims and peer-reviewed research.
