🍆 What Traditional Chinese Medicine reveals about the energetic nature of these foods — from their heat to their tendency to stagnate Qi

🥔 A practical, gentle protocol to test your sensitivity at home — so you can make confident choices instead of guessing

This episode blends Western neuroscience and Eastern food energetics to help you understand how your body responds — without fear, just clarity.
