Can Broccoli Sprouts Fight Cancer? What 30 Years of Research Shows
Broccoli sprouts may be one of the most powerful—and accessible—tools in cancer prevention and support.
In this episode, Dr. Jed Fahey, a nutritional biochemist and one of the world’s leading experts on sulforaphane, breaks down over 30 years of research on this compound found in cruciferous vegetables.
We explore how sulforaphane works at the molecular level, including its impact on detoxification pathways like NRF2, inflammation, and cancer cell behavior. Dr. Fahey also explains the difference between broccoli and broccoli sprouts, why dosing matters, and what current research suggests about real-world use.
We also discuss:
Whether sulforaphane can enhance cancer treatment
Its potential role in targeting cancer stem cells and key pathways involved in metastasis
The difference between supplements and whole foods
Why broccoli sprouts may be one of the simplest, most actionable strategies available today
This episode is designed to help patients and caregivers translate complex science into practical, informed decisions.
