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


Why Vegan Diets May Not Be Good For Your Health with Jayne Buxton

Ep. 582

This episode is brought to you by Mitopure, InsideTracker, and Rupa Health.

The topic of veganism is hotly debated in terms of health and environmental stewardship. But how did the idea that being vegan is the best way to eat for our bodies and the planet develop in the first place? The answer is more complex than you might think. On this episode of The Doctor’s Farmacy, Jayne Buxton challenges the notion that veganism is the cure for disease and climate change and explains how we got here. 

A British-Canadian, Jayne Buxton is an author of both fiction and non-fiction. She spent fifteen years doing research-intensive work as a management consultant for a major firm before writing her 1998 book, Ending the Mother War: Starting the Workplace Revolution, which explored the entrenched positions and false choices faced by women wanting to combine motherhood with careers. Jayne subsequently spent years working in the field of work-life balance, advising both parents and corporations, before turning to writing full time. Her new book, The Great Plant-Based Con, challenges the dominant narrative about the vegan diet and proposes a compelling new perspective.

How To Use Nutrients To Support Our Brain Health

Ep. 607
This episode is brought to you by Beekeeper’s Naturals and Athletic Greens.Your brain is an organ that’s connected to everything else happening in your body. Most of us never learn how to manage our energy and bodies. Instead, we use drugs like sugar, caffeine, and alcohol to self-medicate and manage our energy and moods. We don’t connect our behaviors and choices with how we feel. Many of us get too little good food, nutrients, light, air, water, rest, sleep, rhythm, exercise, community, love, meaning, and purpose. We’re exposed to far too much poor-quality food, stress, toxins, and allergens. But even if you manage all those things correctly, you still might not be getting the right amount of certain nutrients that support your brain and body. That’s where supplements come in.In today’s episode in my series I’m calling Health Bites, I am talking about how to heal our broken brains with the right nutrients.

A Roadmap To Creating Healthy Love And Relationships with Mia Lux

Ep. 606
This episode is brought to you by Rupa Health, BiOptimizers, and InsideTracker.Our relationships affect our health and happiness. The problem is that we’re never taught how to seek, create, nurture, and assess our relationships the same way we do our careers and bank accounts. But the cost of bad relationships on ourselves and our society truly adds up. The relationships many of us grew up around and might consider “normal” are in fact dysfunctional, creating a negative cycle we often don’t even realize we’re in. So how can we find good love, create good relationships, and keep them? That’s what today’s conversation with Mia Lux is all about. Mia merges the playful and the profound—drawing on her experience as a start-up CEO, stand-up comedian, personal growth junkie, and recovering lawyer. For over 7 years, Mia has been an international host, comedian & facilitator, specializing in designing and facilitating top wellness/personal development experiences around the world. Now, Mia is channeling this in the name of love as the Co-Founder & CEO of La Vette, a radical new platform designed to rehumanize dating in the digital era. This episode is brought to you by Rupa Health, BiOptimizers, and InsideTracker.Rupa Health is a place where Functional Medicine practitioners can access more than 2,000 specialty lab tests from over 20 labs like DUTCH, Vibrant America, Genova, and Great Plains.
