Lucia Aronica: “Egg Yolks Don’t Raise Cholesterol (Stanford Scientist Explains) | DSH #1827

At the A4M Conference, Sean Kelly sits down with Dr. Lucia Aronica (Stanford lecturer + nutrigenomics/epigenetics researcher) to break down how food “talks” to your genes — and why most people are missing the nutrients that actually run the “software.” They debunk the cholesterol + eggs myth, explain why choline is a forgotten essential nutrient, and introduce Dr. Lucia’s practical framework for “epi-nutrition”: using specific foods to flip epigenetic switches that support brain health, metabolism, inflammation, and longevity. 🎯 What You’ll Learn 🧬 How the epigenome acts like software that turns genes on/off 🍳 Why egg yolks + cholesterol fear is mostly outdated science 🧠 Why choline matters for brain, liver, and gene regulation 🥗 How to build meals that support gene expression (protein + plants) 🧫 What fermented foods do (pre/pro/postbiotics) ⚖️ What the Stanford twin study results do and don’t prove 🔥 How weight gain creates an epigenetic “fat memory” (and how it fades) Chapters (Timestamps) 0:00 – The cholesterol myth (eggs aren’t the villain) 0:32 – Meet Dr. Lucia Aronica at A4M 0:53 – DNA hardware vs epigenome software 1:28 – “Epi-nutrition”: nourishing genes with food 2:24 – The “usual suspects”: protein + colorful plants + fermented foods 4:30 – Why animal protein matters (B12 + choline) 5:09 – Choline: the forgotten essential nutrient + the “4-yolk formula” 9:59 – Microplastics, salmon, and the 80/20 approach 12:04 – Stanford data: dietary cholesterol vs blood cholesterol 14:07 – Twin study takeaways + long-term vegan caveats (B12/choline) 🎙️ APPLY OR CONNECT 👉 Interested in being a guest?
