Environmental Toxins and the Root of Cancer with Richard Cheng, MD, PhD, ABAARM

“Toxins are everywhere — in our food, water, and air. They damage our mitochondria, disrupt metabolism, and open the door to disease.” —Dr. Richard Cheng

In this episode of the Real Health Podcast, Ron Hunninghake, MD, sits down with Richard Cheng, MD, PhD, ABAARM — physician, researcher, and editor of Orthomolecular Medicine News Service — to explore how environmental toxins and mitochondrial dysfunction are driving today’s rise in chronic illness and cancer.

Dr. Cheng shares how decades of research have revealed the link between toxins, aging, and cancer and why supporting mitochondrial health and reducing environmental exposure may be one of the most effective preventive strategies in modern medicine.

👉 This conversation is part of the Cancer Care Reimagined Speaker Series, leading up to Riordan Clinic’s Cancer Care Reimagined Conference this November.

Highlights include:

→ Why environmental toxins are the top global health threat

→ How mitochondrial dysfunction connects aging, cancer, and chronic disease

→ The overlooked role of heavy metals, seed oils, and ultra-processed foods

→ Practical ways to reduce exposure and support detoxification

→ How vitamin C protects against oxidative damage and supports cell repair
