Colon cancer risk linked to seed oils in early study, tied to inflammation

Researchers have uncovered another potential reason to steer clear of ultraprocessed foods. A recent study published in the medical journal Gut has linked seed oils, commonly found in processed and packaged foods, to an increased risk of colon cancer. The study, conducted by researchers at the University of South Florida (USF) Health and Tampa General Hospital Cancer Institute, analyzed 162 tumor samples from colon cancer patients.

The findings revealed that the tumors contained an excessive amount of molecules that promote inflammation and a deficiency of healing molecules. Dr. Timothy Yeatman, one of the study authors, explained that chronic inflammation in the body, often caused by an unhealthy diet rich in ultraprocessed foods, can hinder the body’s ability to heal wounds, allowing cancer to thrive. This highlights the potential dangers of the Western diet, which includes inflammatory seed oils, added sugars, saturated fats, ultra-processed foods, and chemicals.

In previous studies, the same research team found that an imbalanced diet could increase the risk of various diseases, including heart disease, Alzheimer’s disease, and diabetes. Based on these findings, the researchers recommend a treatment approach known as resolution medicine, which focuses on reversing inflammation using healthy, unprocessed foods rich in omega-3 fatty acids and fish oil derivatives. Regular exercise and adequate sleep also play crucial roles in this approach.

The study was funded by the National Institutes of Health, and clinical trials are currently underway at TGH Cancer Institute to explore the potential benefits of resolution medicine in treating and preventing disease. Dr. Yeatman emphasized the importance of harnessing the body’s natural healing processes to address chronic inflammation and prevent diseases before they develop.

While some experts caution against demonizing all seed oils, they agree that ultraprocessed foods are generally high in sodium, fat, and sugar, while lacking essential nutrients. To reduce the risk of colon cancer and other diseases, experts recommend maintaining a healthy lifestyle that includes a balanced diet rich in fruits, vegetables, and whole grains, along with regular exercise and adequate sleep.

In conclusion, the study sheds light on the potential risks associated with consuming ultraprocessed foods containing seed oils. By making conscious choices about diet and lifestyle, individuals can take proactive steps to protect their health and reduce their risk of developing colon cancer and other chronic diseases.
