Recent research suggests a potential connection between seed oils, commonly found in processed foods, and an elevated risk of colon cancer. A study published in the journal Gut analyzed tumor samples from colon cancer patients and discovered a heightened presence of inflammation-causing molecules and a deficiency in healing molecules.

Dr. Timothy Yeatman, a study author, emphasized the link between unhealthy diets, inflammation, and a suppressed immune system, potentially contributing to cancer growth. He highlighted the broader concerns surrounding the Western diet, citing added sugars, saturated fats, ultra-processed foods, and chemicals as additional culprits.

Previous research by the same team linked imbalanced diets to heart disease, Alzheimer's, and diabetes. They propose "resolution medicine," focusing on unprocessed foods rich in omega-3 fatty acids, exercise, and balanced sleep, to combat inflammation and potentially prevent disease.

However, dietitian Sherry Coleman Collins cautions against definitively linking seed oils to cancer. She notes extensive research demonstrating the benefits of replacing saturated fats with unsaturated fats for cardiovascular health. While acknowledging the need for further research, she emphasizes the overall unhealthy nature of ultra-processed foods due to their high sodium, fat, and sugar content, along with their lack of fiber and nutrients.

Collins recommends lifestyle changes like quitting smoking, reducing alcohol consumption, maintaining a healthy weight, regular exercise, and a fiber-rich diet with ample fruits, vegetables, and whole grains to mitigate colon cancer risk. She suggests using olive oil for low-medium heat cooking and avocado or peanut oils for higher temperatures. She also supports increasing omega-3 fatty acid intake through fatty fish.

Nephrologist Jason Fung acknowledges the preliminary nature of the study, noting the hypothesis linking omega-6 fats in seed oils to inflammation and cancer. While not definitive, he personally avoids seed oils, opting for olive oil and butter.

This research sparks important conversations about dietary choices and their potential impact on health. Further investigation is needed to solidify the link between seed oils and colon cancer.
