Millions may be unknowingly increasing their risk of colon cancer by using certain types of cooking oils, according to a concerning new study. Researchers are sounding the alarm on the potential dangers of consuming large quantities of seed oils, including popular options like sunflower, canola, corn, and grapeseed oil. While these oils have been staples in many kitchens, a government-funded study suggests they could be fueling the rise of colon cancer, particularly in younger adults.
The research, which analyzed tumors from over 80 colon cancer patients, uncovered a potential link between seed oil consumption and the development of this increasingly prevalent disease. Scientists discovered elevated levels of bioactive lipids within the patients’ tumors. These microscopic fatty compounds are byproducts of the body’s breakdown of seed oils and are believed to promote inflammation and hinder the body’s natural defenses against tumors. This dual action makes these lipids a significant concern in the context of cancer development.

The study authors are advocating for a dietary shift away from seed oils, recommending instead the use of oils rich in omega-3 fatty acids, such as olive oil and avocado oil. This recommendation stems from the understanding that omega-3 fatty acids possess anti-inflammatory properties, potentially counteracting the negative effects associated with seed oils.
However, it’s important to note that not all health organizations are in agreement regarding the dangers of seed oils. Major bodies like the American Heart Association maintain that there is insufficient evidence to suggest that moderate consumption of seed oils contributes to cancer or heart disease. They argue that seed oils can be part of a healthy diet and may even offer benefits like lowering cholesterol. This difference in opinion highlights the ongoing debate and the need for further research in this area.
Despite the official stance of some organizations, a growing movement is raising concerns about seed oils due to emerging studies linking them to inflammation and increased risk of various health issues, including heart disease and diabetes. Figures like Robert F Kennedy Jr. have publicly voiced concerns, suggesting that Americans are being “unknowingly poisoned” by these oils. This public discourse adds another layer to the discussion surrounding the health impacts of seed oils.
The findings come as rates of colon cancer have surged in young Americans

These findings arrive at a critical time as colon cancer rates are alarmingly increasing among younger Americans. Early-onset diagnoses, affecting individuals under 50, are projected to surge dramatically in the coming years. While a definitive cause for this rise remains elusive, ultra-processed foods, often containing high levels of seed oils, are considered a potential contributing factor due to their inflammatory properties.
The average American’s consumption of seed oils has drastically increased over the decades, reaching approximately 100 pounds per year, a staggering 1000-fold increase since the 1950s. This dramatic shift in dietary habits coincides with the increased availability and affordability of seed oils following World War II.
Published in the journal Gut, the recent study examined tumor samples from patients across a wide age range (30 to 85). The results indicated a significant elevation of bioactive lipids in the tumors of colorectal cancer patients compared to healthy fats. This finding strengthens the hypothesis that seed oil consumption and the resulting bioactive lipids play a role in colon cancer development.

Seed oils are naturally rich in omega-6 and polyunsaturated fatty acids. Upon consumption, these fatty acids undergo a biochemical process, converting into bioactive lipids. This process, occurring within plant cells, ultimately leads to the formation of arachidonic acid, which is further converted into eicosanoids, the type of bioactive lipid found in high levels in the tumors studied. The presence of these bioactive lipids in colon tumors suggests the body is indeed metabolizing them from dietary sources, primarily omega-6 fatty acids.
Excessive consumption of omega-6 fatty acids has been linked to inflammation in the colon. In the context of colon cancer, chronic inflammation creates an environment conducive to cancer development. Inflammation triggers rapid cell division and regeneration in the colon lining, increasing the likelihood of cancer-causing mutations. Furthermore, chronic inflammation weakens the immune system, diminishing its ability to eliminate abnormal cells before they develop into tumors.

Dr. Timothy Yeatman, the lead study author from the USF Health Morsani College of Medicine, emphasizes the connection between unhealthy diets, inflammation, and cancer. He explains that cancer can be viewed as a “chronic wound that won’t heal,” and a diet rich in ultra-processed foods, and consequently seed oils, impairs the body’s healing capacity due to persistent inflammation and immune suppression, thus facilitating cancer growth.
Based on these findings, the researchers propose that therapeutic approaches focused on reducing inflammation through healthy, unprocessed fats like fish oil could be beneficial in supporting the body’s natural healing mechanisms and potentially revolutionizing cancer treatment beyond traditional drug-based interventions. This approach, as Dr. Yeatman suggests, could be a crucial step towards addressing chronic inflammation and preventing diseases proactively.
