The Exam Room by the Physicians Committee

What if eating the right vegetables could make exercise feel easier while simultaneously lowering your blood pressure?
In this episode of The Exam Room Podcast, host Chuck Carroll is joined by metabolic health expert Cyrus Khambatta of Evolution Health to break down the science behind nitrate-rich vegetables and how they dramatically improve blood flow, oxygen delivery, endurance, and recovery.
You'll learn how nitrates convert into nitric oxide, why foods like beets, arugula, spinach, and celery outperform supplements, and how simple dietary changes can enhance athletic performance — even if you're not an athlete.
We also clear up confusion about nitrates in processed meats, explain why mouthwash can block benefits, and reveal the ideal timing and amounts for maximum results.
In this episode, you'll discover:
• How nitrates lower blood pressure naturally
• Why nitric oxide improves endurance & oxygen efficiency
• The best nitrate-rich vegetables to eat daily
• How nitrates support mitochondria & cellular energy
• When and how much to eat for exercise performance

Inflammation is at the center of many of today's most common chronic diseases — but what if the real starting point isn't where most people think?
 
In this episode of The Exam Room Podcast, host Chuck Carroll is joined by gastroenterologist and best-selling author Dr. Will Bulsiewicz for a wide-ranging and deeply human conversation about gut health, chronic inflammation, and the hidden role that stress, loneliness, and modern lifestyle play in making us sick.
 
Drawing from his new book Plant-Powered Plus, Dr. Bulsiewicz explains why the gut is a central command center for the immune system and the brain, and how dysfunction in the microbiome can drive everything from digestive distress to depression, anxiety, and long-term disease. He also opens up about his own personal health journey — including burnout, weight gain, and metabolic illness — and how healing his gut transformed both his life and his medical practice.
 
This episode goes beyond food to explore the science of the brain-gut-immune connection, the impact of chronic stress and isolation on inflammation, and why true healing requires more than just changing what's on your plate. If you've ever felt successful on the outside but unwell on the inside, this conversation offers clarity, compassion, and hope.
