A Mediterranean diet is high in vegetables, fruits, whole grains, and olive oil and low in meat, sweets, and saturated fat. It is linked to lower risks of cancer and relief of some symptoms and imbalances common among people with cancer.

How do experts use a Mediterranean diet?

Both medical groups and integrative experts provide recommendations for a Mediterranean diet in treating people with cancer. Learn more about the approaches and meanings of recommendations: Integrative Oncology Programs and Expert Guidelines ›

Clinical practice guidelines

2013 clinical practice guidelines from the American College of Chest Physicians recommend nutritional modification toward a diet rich in non-starchy vegetables and fruits, limiting consumption of a large amount of red meat and processed meat.

The 2020 survivorship care for healthy living guidelines recommend a plant-based diet consistent with a Mediterranean diet:

  • Plant-based food is made from vegetables, legumes, fruits, grains, nuts, seeds, or oils.
  • Eat plant-based food for at least half of your diet.
  • Eat lots of vegetables, fruits, and whole grains. 
  • Eat 3 or fewer servings of soy a day.
  • Eat animal-based food—meat, poultry, fish, eggs, milk, or honey—for half or less of your diet.  
  • Eat less than 18 ounces of red meat a week.

Published protocols, programs, and approaches

A Mediterranean diet is used in programs, approaches, and protocolsa package of therapies combining and preferably integrating various therapies and practices into a cohesive design for care from these integrative oncologists, drawing from both scientific research and observations from years or even decades of treating people with cancer.

This book introduces the concept of the Mix of Six, which is identical to six of our 7 Healing Practices ›

Dr. Cohen and Ms. Jefferies explain that while each plays an inde­pendent role, the synergy created by all six factors can radically transform health, delay or prevent many cancers, support conventional treatments, and significantly improve quality of life.

Traditional medicine

A Mediterranean-style diet is consistent with both Ayurvedic and traditional Chinese medicine approaches.

The focus on a Mediterranean diet’s plant-based meals with healthy fats is very much aligned with Ayurvedic recommendations for diet.1Deva A. The Ayurvedic Perspective on Modern Diets. Banyan Blog. August 31, 2021. Viewed June 16, 2017.

Traditional Chinese medicine has long held that “grains, meat, vegetables and fruit should be used in proper proportions so as to maintain the normal function of human body.”2Wu Q, Liang X. Food therapy and medical diet therapy of traditional Chinese medicine. Clinical Nutrition Experimental. 2018 Apr;18:1-5.

A healthy eating pattern includes:

  • A variety of vegetables—dark green, red and orange, fiber-rich legumes (beans and peas), and others
  • Fruits, especially whole fruits in a variety of colors
  • Whole grains

A healthy eating pattern limits or does not include:

  • Red and processed meats
  • Sugar-sweetened beverages
  • Highly processed foods and refined grain products

American Institute for Cancer Research

These recommendations include eating a diet rich in whole grains, vegetables, fruits, and beans, which aligns with a Mediterranean diet.

Survey of naturopathic oncologists

A 2018 survey identified a Mediterranean diet as one of the most frequently identified interventions used by members of the Oncology Association of Naturopathic Physicians.3Seely D, Ennis JK, McDonell E, Zhao L. Naturopathic oncology care for thoracic cancers: a practice survey. Integrative Cancer Therapies. 2018 Sep;17(3):793-805.

Miles Hassell, MD, author of Good Food, Great Medicine

Dr. Hassell recommends eating a Mediterranean diet.

Expert commentary

CancerChoices Senior Clinical Consultant Laura Pole, RN, OCNS, February 11, 2018: Several other diets—also plant-based with many elements similar to the Mediterranean diet—are used for cancer prevention and/or for people with cancer. Some examples: 

  • The American Institute for Cancer Research recommends a plant-based diet very similar to the Mediterranean diet. The AICR website describes their cancer protective diet as consisting of mostly plant foods, with the addition of dairy, eggs, fish, poultry and moderate amounts of meat, and with minimal processing and little added sugar and fat.
  • Ornish Spectrum Diet: used as part of the Ornish Lifestyle Medicine Program for Prostate Cancer
  • Keith Block’s Life over Cancer Core Diet Plan4Block KI. Life over Cancer: The Block Center Program for Integrative Cancer Treatment. New York: Bantam Dell. 2009.
  • DASH (dietary approaches to stop hypertension) eating plan from the National Heart, Lung, and Blood Institute
  • The MIND Diet (Mediterranean-DASH Intervention for Neurodegenerative Delay) is a hybrid of the Mediterranean and DASH diets, originally tested to see if it has effects on cognitive function but also studied in specific cancers. For general information see The MIND Diet: What to Know.
