How Early Nutrient Status Set Your Slopes For Disease & Aging | Dr Federica Amati | EP#427

Visit The Proof website for the full show notes and supporting studies: https://theproof.com/podcast/ Simon's personal supplement stack: https://hub.theproof.com/supplements Most of us think of pregnancy as the starting line for a child's health. In this episode, Dr Federica Amati makes a compelling, evidence-based case that the real window opens months earlier, in the roughly 90 days before conception, and that it shapes everything from fertility to a child's lifelong risk of disease. It is one of the most practical and hopeful conversations I've had on the topic. Federica is the Head Nutritionist at ZOE and holds a PhD in Clinical Medicine Research from Imperial College London. She studies how nutrition across the life course, and especially in the first 1,000 days, sets the trajectory for our long-term health.
