Can sunlight, oral health, and “normal” lab results be silently driving chronic disease?
In this episode of The Pod of Inquiry, Dr. Stephen Barrett sits down with Dr. Thomas Lewis—MIT chemist, electrophysiologist, and independent medical researcher—to explore overlooked factors that may influence long-term health. From sunlight and mitochondrial function to root canals, cholesterol, and laboratory reference ranges, this conversation challenges conventional assumptions and examines evidence behind alternative perspectives on chronic disease.
Dr. Lewis shares insights gained from years of mentoring under renowned ophthalmologist Dr. Trempe and explains why many chronic illnesses may have root causes that extend beyond individual organs. (The Hidden Causes of Chronic Disease)
In This Episode you’ll discover:
- The science behind sunlight, vitamin D, and mitochondrial health
- The connection between root canals, oral bacteria, and chronic disease
- Why “normal” blood test results may not always reflect optimal health
- Cholesterol, LDL, and the debate surrounding statins
- Boron, iodine, calcium metabolism, and joint health
- How to use AI as a research tool without being misled
- A root-cause approach to understanding chronic illness
Whether you’re interested in longevity, functional medicine, preventive healthcare, or the latest debates in medical science, this episode offers a thought-provoking discussion that encourages critical thinking and deeper exploration.

Author Biography
Dr. Thomas Lewis, PhD — MIT Chemist, Electrophysiologist & Root Cause Medicine Practitioner
Dr. Lewis is a Medical Scientist with a Ph.D. in Chemistry from MIT and advanced certifications from the Harvard School of Public Health in Toxicology and Nutrition in the Public Interest. He is an entrepreneur and healthcare professional with expertise in toxic substances, healing process development, biotechnology, health technology, medical protocol, and process development.
Dr. Lewis is the author of “Foundational Medicine,” which takes the best that Functional Medicine offers and efficiently delivers it to patients. Importantly, foundational medicine is significantly less expensive than functional medicine, thus making this approach a viable alternative to standard-of-care and population health. He developed a 24-hour training course suitable for traditional medical doctors, DPC doctors, health coaches, and functional medicine doctors to help them transition to economical health delivery, which is necessary to change the current failed sick-care paradigm.
He has worked with senior researchers and clinicians at Harvard Medical School for decades. He has developed science and evidence-based programs for chronic disease root cause prevention, screening, diagnosis, and treatment. His focus has been on Alzheimer’s disease and the most serious eye diseases, such as macular degeneration and glaucoma, as his father suffered from glaucoma and died from Alzheimer’s. Dr. Lewis opened the first-of-its-kind Alzheimer’s prevention, screening, early detection, and treatment center in the Orlando, Florida, area in 2014.
He worked closely with Dr. Clement Trempe, 41 years at Harvard Medical School, one of the few doctors in the world who treated chronic eye diseases as systemic inflammatory conditions – and successfully reversed these conditions. What Dr. Trempe showed is that when you treat eye diseases systemically, brain health also improves. This is not a coincidence, as the retina is an outcropping of the brain. Through this work, Dr. Trempe developed his protocol for diagnosing, treating, and reversing Alzheimer’s disease, which is now an integral part of the health offerings of Dr. Lewis through www.healthrevivalpartners.com.
Dr. Lewis has written six books: “The End of Alzheimer’s – The Brain and Beyond,” (2nd Ed.), “Uncovering Chronic Inflammation and Hidden Infections,” and “Quarterback Your Own Health – How to Take and Lower Your Chronic Disease Temperature;” “Cancer Is an Infectious Disease;” and a two-volume set titled, “Health Freedom Lost.” He has several patents and numerous publications. The most recent patent involves identifying and using physiological and pathological biomarkers that can accurately predict future morbidity (disease) and mortality. This risk is presented through a single value coined your “Chronic Disease Temperature™.
He has also created a software-based medical intake form designed to determine the current and future risks of accelerated aging and chronic disease in individuals.

Episode Overview
Dr. Thomas Lewis — MIT-trained chemist, electrophysiologist, and longtime protégé of Harvard ophthalmologist Dr. Trempe — joins Dr. Barrett for a sweeping, paradigm-challenging conversation. They tackle the fatal flaw in standard lab reference ranges, the underappreciated physiological necessity of sun exposure, the systemic dangers of root canals and periodontal bacteria, the oral microbiome’s role in cardiovascular health, and a lucid reframing of cholesterol and lipoproteins. Dr. Lewis also introduces his new low-cost root cause medicine platform, DocDocFrugal.com, designed to democratize access to functional and integrative care.
