The Doctor's Farmacy with Mark Hyman, M.D.


The Functional Medicine Approach To Cancer and Cancer Recurrence with Dr. Elizabeth Boham

Numerous things can contribute to cancer development and cancer recurrence. Studies show diet, exercise, thoughts, feelings, and environmental toxins all influence the initiation, growth, and progression of cancer. And when it comes to treating cancer, we are good at cutting it, burning it, and poisoning it with surgery, radiation, and drugs, but many doctors fail to treat the root cause of the cancer. Functional Medicine empowers patients and practitioners to achieve the highest expression of health by working collaboratively to address the root causes of disease. For example, a Functional Medicine practitioner might say that yes, we still need radiation and other conventional approaches, but what else can we do? 

In this mini-episode, Dr. Hyman is joined by Dr. Elizabeth Boham to discuss the Functional Medicine approach to cancer and cancer recurrence prevention. Dr. Boham shares patient cases as well as her own experience with a breast cancer diagnosis.

Elizabeth Boham is a physician and nutritionist who practices functional medicine at The UltraWellness Center in Lenox, MA. Through her practice and lecturing she has helped thousands of people achieve their goals of optimum health and wellness. She witnesses the power of nutrition every day in her practice and is committed to training other physicians to utilize nutrition in healing. Dr. Boham has contributed to many articles and wrote the latest chapter on Obesity for the Rankel Textbook of Family Medicine. She is part of the faculty of the Institute for Functional Medicine and has been featured on the Dr. Oz show and in a variety of publications and media including Huffington Post, The Chalkboard Magazine, and Experience Life. Her DVD Breast Wellness: Tools to Prevent and Heal from Breast Cancer explores the functional medicine approach to keeping your breasts and whole body well.

How To Recover From Chronic Lyme And Tick Diseases with Dr. Todd LePine

Lyme disease and other tick-borne diseases often go undiagnosed or are misdiagnosed. This is partially because Lyme mimics other illnesses such as the flu, manifesting as diverse symptoms including headaches, muscle aches, stomach ulcers, constipation, and joint pain, making diagnosing and treating Lyme very difficult. Left unchecked, Lyme symptoms can worsen, creating a long-running inflammatory response and autoimmune illness. Lyme disease, or borreliosis, is caused by the bacterium Borrelia burgdorferi, which can proliferate to every area in your body. The good news is that with some work and effort, you can successfully treat Lyme disease.In this episode, Dr. Hyman sits down with Dr. Todd LePine to discuss the Functional Medicine approach to identifying and treating chronic Lyme and other tick-borne diseases.Dr. LePine graduated from Dartmouth Medical School and is Board Certified in Internal Medicine, specializing in Integrative Functional Medicine.

Do You Have To Eat A Ketogenic Diet All Of The Time To Get Its Benefits? with Mark Sisson

The ketogenic diet has gained a lot of popularity in the past couple of years. If you’re not quite sure what it is, why it could be beneficial, or you’re well-acquainted with it and just want to learn more, this episode is for you. The ketogenic diet, or keto as it’s called, is a high-fat low carbohydrate diet. While some people take this to mean loads of conventionally raised meat and dairy, the true (and beneficial version) means lots of beneficial fats from things like avocados, nuts and seeds, and coconut; high-quality protein from clean sources like grass-fed meat and pasture-raised eggs; and plenty of non-starchy vegetables.To hash out more of the details about keto and how it can support good health, I was excited to talk with my friend and one of the leading voices in the Paleo/Primal and keto movements, Mark Sisson. Mark is the founder of the popular daily health blog, Mark’s Daily Apple, godfather to the Primal food and lifestyle movement, and the New York Times bestselling author of The Keto Reset Diet. His latest book is Keto for Life, where he discusses how he combines the keto diet with a Primal lifestyle for optimal health and longevity. Mark is the author of numerous other books as well, including The Primal Blueprint.This episode is sponsored by Joovv, chili, and my Sleep Master Class.I recently discovered Joovv, a red light therapy device.

How COVID-19 Shines A Light On Our Broken Food System with Dr. Dariush Mozaffarian

Only 12% of us in the US are metabolically healthy—it’s pretty alarming when the healthy population is the minority. And in the age of COVID-19, it’s important to recognize that those with a chronic disease are at an exponentially higher risk of hospitalization than someone who is metabolically healthy. If we as a population were healthier (think less obesity, type 2 diabetes, cardiovascular disease, cancer, etc.), the evidence supports that we’d be faring much better throughout this pandemic. Of course, a major driver of chronic diseases and the risks they create is our food system. We can’t expect to be a resilient population if we aren’t feeding our bodies real food with real nutrients we can use to function optimally.To dig into this topic further, I was excited to sit down with Dr. Dariush Mozaffarian on this episode of The Doctor’s Farmacy. Dr. Mozaffarian is a cardiologist, Dean and Jean Mayer Professor at the Tufts Friedman School of Nutrition Science and Policy, and Professor of Medicine at Tufts Medical School. As one of the top nutrition institutions in the world, the Friedman School’s mission is to produce trusted science, future leaders, and real-world impact. Dr. Mozaffarian has authored more than 400 scientific publications on dietary priorities for obesity, diabetes, and cardiovascular diseases, and on evidence-based policy approaches to reduce these burdens in the US and globally. He has served in numerous advisory roles including for the US and Canadian governments and, in 2016, Thomson Reuters named him as one of the World’s Most Influential Scientific Minds.For context, this interview was conducted on April 30, 2020.Here are more of the details from our interview:Three ways COVID-19 influences food and nutrition, and visa versa (3:28)How our national health and economic outcomes from COVID-19 might be different were we a metabolically healthy society(7:37)We can improve our metabolic health in real time (9:53)Micronutrients and their potential for preventing and reducing COVID-19 severity(11:32)Strategies to address our chronic disease pandemic and problems with our food system (28:41)How obesity is affecting our military and national security (33:23)Why we need a coordinated national organizing office around food and nutrition policy (48:18)Functional Medicine for our food system (54:55)Obstacles to changing and improving our food system (56:12)Educating policymakers through strategic collaboration among stakeholders (1:00:30)Find the “Report of the 50th Anniversary of the White House Conference on Food, Nutrition, and Health: Honoring the Past, Taking Actions for our Future” at Dr. Mozaffarian on Twitter @Dmozaffarian.
