Thirty Years of Clinical Research

One Mission.
Fighting Cancer with Food.

With a lifetime dedicated to fighting cancer with food, Dr. Mary M. Flynn has spent decades showing how a plant-based diet rich in extra virgin olive oil is a powerful tool for recovery.

Since 1999, her research has focused on using specific, high-quality ingredients to help patients maintain their strength and metabolic health during and after treatment.

Unlike many conventional dietary plans, her approach uses the natural, protective benefits of olive oil to turn your daily meals into a proactive part of your healing journey.

Her Mission

Pioneering a Plant-Based Olive Oil Diet

With a lifelong focus on food as medicine, Professor Flynn has dedicated her research since 1999 to the protective benefits of extra virgin olive oil. She pioneered a specialized plant-based, olive oil-rich diet to serve as a clinical cornerstone for weight management in oncology patients.

Beyond the clinic, she has adapted this dietary model to combat food insecurity among food pantry clients. This work also extends to the Warren Alpert Medical School, where she teaches medical students how to apply these practical nutritional solutions.
