Popular cooking oils used in ultra-processed Western diets may be causing a surge in colon cancer cases, a new US government-led study has shown.

Unhealthy seed oils like sunflower, grapeseed, canola, and corn could trigger chronic inflammation in the body, the groundbreaking research found.

Until now evidence linking cooking oil to colon cancer has been inconclusive.

But the recent American study identified seed oils as the possible contributing factor when they examined tumours from more than 80 people with colon cancer, aged between 30 and 85.

The tumours showed increased levels of bioactive lipids, which are small oily molecules produced when the body metabolises seed oils, compared to healthier fats, according to the study published in the Gut journal.

As well as increasing inflammation, bioactive lipids hinder the bodyā€™s natural healing process and foster tumour growth.

Oils rich in omega-3 fatty acids, found in avocados and olives, are a healthier alternative, the researchers said.

Renowned physician-scientist Dr. Timothy Yeatman said the findings stressed an urgent need to reevaluate parts of the Western diet, including added sugars, saturated fats, ultra-processed foods, chemicals and inflammatory seed oils.

ā€œIt is well known that patients with unhealthy diets have increased inflammation in their bodies,ā€ said Dr. Yeatman, who is also an associate centre director for Translational Research and Innovation at the TGH Cancer Institute.

ā€œWe now see this inflammation in the colon tumours themselves, and cancer is like a chronic wound that wonā€™t heal - if your body is living off of daily ultra-processed foods, its ability to heal that wound decreases due to the inflammation and suppression of the immune system that ultimately allows the cancer to grow.ā€

But top US health institutions have clarified that consuming moderate amounts of seed oils as part of a balanced diet has not been shown to cause cancer.
