Western Diet Promotes Return of Colon Cancer - Food and Health Communications

A typical modern Western diet is characterized by a high intake of red meats, fatty dairy products, processed meats, sweets and desserts, French fries, and refined grains. Two large prospective studies found people who consume such a dietary pattern are significantly more likely to develop colon cancer than people consuming a more prudent diet with less of those typical American diet foods but more fruits, vegetables, whole grains, beans, and moderate amounts of fish and poultry.1, 2 Colon cancer is on the rise in many Asian and European countries, as fast food restaurants, processed foods, and growing affluence enable more and more people to adopt a more Westernized dietary pattern. Clinical trials and epidemiological evidence suggests that a least 80% of the colon cancers in the United States could be prevented if Americans were to adopt a better diet.

While the Western dietary pattern promotes colon cancer, little research has been done to determine if sticking with it after colon cancer is diagnosed and treated makes a difference. Dr. Jeffrey Meyerhardt at the Dan-Farber Cancer Institute in Boston lead a team of researchers who followed 1009 people diagnosed and treated (with surgery and chemotherapy) for stage III colon cancer for a median of 5.3 years.3 These researchers used a Food Frequency Questionnaire to determine if dietary pattern would influence the risk of developing a recurrence of colon cancer. Of the original 1009 subjects, 324 had a colon cancer recurrence and 223 of them died during follow-up from a recurrence of their colon cancer. Another 28 subjects died from other causes but without evidence of their cancers recurring. During follow-up the top 20% of subjects with the most Westernized dietary pattern were found to be about 3 times more likely to develop and die from a recurrence of their colon cancer than the 20% who consumed the least Western-style diets.

This new study suggests even adopting a healthier diet after being treated for colon cancer markedly increases one’s odds of remaining cancer free and avoiding death from colon cancer and other causes.

Judy’s passion for cooking began with helping her grandmother make raisin oatmeal for breakfast. From there she earned her first food service job at 15, was accepted to the world-famous Culinary Institute of America at 18 (where she graduated second in her class), and went on to the Fachschule Richemont in Switzerland where she focused on pastry arts and baking. After a decade in food service for Hyatt Hotels, Judy launched Food and Health Communications to focus on flavor and health. She graduated with Summa Cum Laude distinction from Johnson and Wales University with a BS in Culinary Art, holds a master’s degree in Food Business from the Culinary Institute of America, 2 art certificates from UC Berkeley Extension, and runs a food photography studio where her love is creating fun recipes.

Judy received The Culinary Institute of America’s Pro Chef II certification, the American Culinary Federation Bronze Medal, Gold Medal, and ACF Chef of the Year. Her enthusiasm for eating nutritiously and deliciously leads her to constantly innovate and use the latest in nutritional science and Dietary Guidelines to guide her creativity, from putting new twists on fajitas to adapting Italian brownies to include ingredients like toasted nuts and cooked honey. Judy’s publishing company, Food and Health Communications, is dedicated to her vision that everyone can make food that tastes as good as it is for you.
