How to dramatically improve the metabolic health and performance of your skeletal muscle: Wisdom Wednesdays

https://api.omny.fm/orgs/2fb3740d-3436-44af-8cc0-a91900716aa5/clips/cc985855-7136-403e-953d-b40100930d1f/transcript

Dr James Thompson joins me for a practical conversation about why heart disease still leads as a global killer, why cholesterol and calcium scoring have limits, and how advanced imaging is changing prevention. We also cover exercise, lifestyle, and the role AI is starting to play in cardiac imaging.

Heart disease often starts silently years before a scan or cholesterol test raises the alarm. Dr. James Thompson reveals why a zero-calcium score can still miss dangerous plaque, and why the future of prevention may depend on looking much earlier, and much deeper. We break down the limits of total cholesterol, LDL, and calcium scoring, then show how APO B, LP little A, CT coronary angiography, and cardiac MRI change the picture. If you have ever been told you are "fine" because your cholesterol is normal or your calcium score is low, this conversation will make you rethink what that actually means.

 

Key topics
Heart disease remains the biggest killer
Dr Thompson explains why cardiovascular disease is still the number one public health issue and why it affects men and women differently, especially after menopause.
Why cholesterol is only part of the picture
They discuss why total cholesterol and LDL can miss risk, and why APO B and Lp(a) can be more useful markers in specific cases.
What a calcium score can and cannot tell you
A calcium score detects calcified plaque in the coronary arteries, but it can miss non-calcified, high-risk plaque.
The problem with false reassurance
A zero calcium score does not always mean zero disease, especially in younger people or those with early, vulnerable plaque.
Why CT coronary angiography is more revealing
Dr Thompson explains how contrast-enhanced CTA can show the actual coronary arteries, plaque burden, plaque composition, and flow-related risk.
How CT imaging works in practice
They cover heart-rate control, breath-holding, EKG gating, IV contrast timing, and why coronary CTA is technically demanding but highly informative.
MRI of the heart brings different strengths
Cardiac MRI is described as the best tool for tissue characterization, function, fibrosis, and flow, while CT still wins for spatial resolution of the coronary arteries.
Exercise and movement are part of prevention
Paul and Dr Thompson connect imaging with lifestyle, arguing that inactivity is not neutral and that movement is fundamental to cardiovascular health.
AI is accelerating cardiac imaging
Dr Thompson explains how AI is helping quantify plaque, flow, and inflammation, and why radiology is one of the main areas where AI is already being applied.
Why early detection matters
The conversation repeatedly returns to prevention, especially for people in their 30s, 40s, and 50s who may feel well but already have disease.

Action items
Ask your doctor whether your current heart-risk assessment is enough for your age, family history, and symptoms.
Consider whether cholesterol alone is giving you a false sense of reassurance.
If you have questions about calcium scoring or CTA, discuss the difference with a clinician who understands cardiac imaging.
Treat exercise and daily movement as non-negotiable parts of heart prevention.
If you are in your 30s, 40s, or 50s, do not assume heart disease is a problem for later in life.

AI, Imaging, and the Future of Preventing Heart Attacks Early with Dr James Thompson

https://api.omny.fm/orgs/2fb3740d-3436-44af-8cc0-a91900716aa5/clips/ac425502-7394-4e83-84c5-b4c800599340/transcript

Fascinating research on how breathwork can clean your brain: Wisdome Wednesdays

https://api.omny.fm/orgs/2fb3740d-3436-44af-8cc0-a91900716aa5/clips/ad27926d-ce87-47d0-965a-b4c6008b9e52/transcript

Dr. Nicole Bijlsma explains why the built environment matters for health, from mould and air quality to electromagnetic fields and chemical exposures. She shares practical, high-impact changes for bedrooms, water, skincare, cleaning, and home setup that can reduce everyday exposure and support better sleep, immunity, and wellbeing. We discuss why old homes and new homes each have different risks, how Wi-Fi and electrical wiring can affect sleep, and why water filtration is a non-negotiable if you want to reduce chlorine, PFAS, and fluoride exposure. Nicole also covers the biggest chemical exposures on skin, the most useful cleaning swaps, and why over-sanitising may be backfiring on allergy risk.

Key topics
Nicole shares how personal health issues led her into building biology and why she started training people to assess homes for environmental hazards.
The difference between old homes and new homes, including condensation, mould, poor maintenance, tight building envelopes, and off-gassing from imported furnishings.
Why carpets can act like a reservoir for dust, pest debris, asbestos, lead paint, and chemicals, especially for infants crawling on the floor.
The three EMF categories Nicole prioritises - radio frequencies, AC magnetic fields, and dirty electricity.
Why a Wi-Fi router in the bedroom is a major issue, and why hardwiring or powering routers down at the wall is the best fix.
Why the bedroom is the top health priority, and how to set it up for better sleep by removing Wi-Fi devices, phones, extenders, and boosters.
Why inverter and solar battery placement matters, and why distance is the main defense against magnetic fields.
Why reverse osmosis is the best option for drinking water when fluoride is a concern, while whole-house filtration helps with chlorine, sediment, PFAS, and many other contaminants.
Nicole shares why alkaline water is not her recommendation, and why stomach acid matters for digestion, protein breakdown, and nutrient absorption.
The biggest chemical exposures on the body, especially perfumes, aftershaves, artificial fragrances, and air fresheners.
Why jojoba oil, rose hip oil, wool, hemp, cotton, and fragrance-free basics are the safer everyday choices for skin and home use.
