I talk a lot about what we eat for our health. But what about the air we breathe at home? If you or your kids have asthma, constant sniffles, a lingering cough, sinus issues, or you’ve noticed damp patches and that musty smell, this episode could change how you think about your home. As a new dad, I'm personally really interested in how our home environment shapes early immune development. This conversation made me think differently about ventilation, condensation and what really matters. My guest is Dr Peter Cook, a Wellcome Trust Sir Henry Dale Fellow at the MRC Centre for Medical Mycology at the University of Exeter. His research looks at how airborne fungal spores interact with the immune system and drive allergic and asthmatic disease, an area that has been surprisingly neglected. 🕒 Timecodes 00:00 - What is mould? 02:38 - What types of mould are found in homes? 05:28 - Is mould exposure increasing in modern homes? 07:27 - Why does mould grow more in winter? 09:07 - Do building materials affect mould growth? 10:18 - What is a safe level of mould exposure? 11:46 - How do you test for mould in your home? 17:12 - Who’s more vulnerable to mould exposure? 22:49 - Which mould species are linked to asthma and allergies? 27:10 - Why mould can trigger allergies 31:58 - Mycotoxins 34:15 - Why are some people more sensitive to mould? 36:54 - Why are asthma and mould allergies increasing? 38:32 - Can mould cause chronic fatigue or brain fog? 41:24 - Practical ways to reduce mould at home 44:43 - Are dehumidifiers and air purifiers worth it? ---------------------------------------------------------------------------------------------------------- LEARNING TO EAT WELL EVERY DAY 🥗 Download a FREE 7 day meal plan: https://tdk.link/mealplan_yt 🔥 Learn about Inflammation - FREE 4 part mini-series here: https://tdk.link/infl_series_yt 🥑 Heal yourself with food: https://tdk.link/heal_yt 🎤 Listen to experts on the podcast: https://tdk.link/pod_yt 👨🏽‍💻 Browse articles on the website: https://tdk.link/web_yt 📚 Check out my cookbooks: https://tdk.link/books_yt LET'S BE FRIENDS 📷 Instagram: https://tdk.link/tdk_insta_yt 📹 Subscribe: https://tdk.link/ytsubscribe 🙋🏽‍♂️ Facebook: https://tdk.link/tdk_fb_yt 🐦 Twitter: https://tdk.link/tdk_tw_yt 👔 LinkedIn: https://tdk.link/tdk_li_yt
