What if it’s increasing your risk of a heart attack or stroke, without you ever feeling a thing? In this episode, Professor Tim Spector reveals why blood pressure is one of the most overlooked – and most dangerous – health issues today. He explains why “normal for your age” might not be safe at all, why medication alone isn’t the full answer, and how small, daily changes could dramatically reduce your risk of serious disease. Can your gut microbes raise your blood pressure? Can a banana be as powerful as a pill? Is beetroot juice really three times more effective than cutting salt? You’ll also learn why 80% of the salt we eat isn’t from the shaker, how stress and sleep secretly push your pressure up, and what most doctors still miss when treating hypertension. If you’ve ever been told your blood pressure’s “fine” — or never measured it at all — this episode might change the way you think about your future health. 🌱 Try our new plant based wholefood supplement - Daily30: https://zoe.com/daily30?utm_medium=zoe_podcast&utm_source=podcast_platform&utm_campaign=d30 Follow ZOE on Instagram | https://www.instagram.com/zoe/ Timecodes 00:00 Why blood pressure raises dementia risk 03:29 What actually is high blood pressure? 05:57 Why everyone should own a blood pressure monitor 07:01 What your blood pressure reading really means 09:59 Stress isn’t the main cause of high blood pressure 11:28 The $20 gadget that can save your life 13:17 When to see a doctor about blood pressure 14:35 The mystery of what causes high blood pressure 16:57 The truth about salt and your blood pressure 18:28 Why reducing salt didn’t work for Tim 20:09 What blood pressure meds actually do 22:04 Why high blood pressure is so dangerous 24:20 How blood pressure quietly damages your brain 27:18 Is it too late to lower your blood pressure? 31:31 How your gut microbes affect blood pressure 34:14 Why potassium matters more than salt 36:29 How sleep, stress & saunas impact your blood pressure 38:58 The real source of excess salt in your diet 41:37 Should you switch to potassium salt? 49:30 Beetroot juice: better than salt restriction? 📚Books by our ZOE Scientists The Food For Life Cookbook | https://amzn.to/4amfIMX Every Body Should Know This by Dr Federica Amati | https://amzn.to/4blJsLg Food For Life by Prof. Tim Spector | https://amzn.to/4amZinu Free resources from ZOE: Live Healthier: Top 10 Tips From ZOE Science & Nutrition | https://zoe.com/freeguide Gut Guide - For a Healthier Microbiome in Weeks | https://zoe.com/gutguide Studies mentioned in this episode: Nonpharmacologic Interventions for Reducing Blood Pressure in Adults With Prehigh blood pressure to Established high blood pressure, Journal of the American Heart Association (2020) https://pmc.ncbi.nlm.nih.gov/articles/PMC7792371/ Long-Term Effect of Intensive vs Standard Blood Pressure Control on Mild Cognitive Impairment and Probable Dementia in SPRINT, Neurology (2025) https://www.neurology.org/doi/10.1212/WNL.0000000000213334 Blood pressure reduction and all-cause dementia in people with uncontrolled high blood pressure: an open-label, blinded-endpoint, cluster-randomized trial, Nature Medicine (2025) https://www.nature.com/articles/s41591-025-03616-8 High blood pressure Associated With Hearing Loss and Tinnitus Among Hypertensive Adults at a Tertiary Hospital in South Africa, Frontiers in Neurology (2022) https://pmc.ncbi.nlm.nih.gov/articles/PMC8965715/ Have feedback or a topic you'd like us to cover?
