Saed News: Recent research findings show that the oil you cook with every day may silently increase your risk of cancer, but this depends on several factors.
According to SAEDNEWS, researchers have found a concerning link between linoleic acid found in many common cooking oils and aggressive breast cancer (triple-negative type). This news raises major questions about our dietary choices, but before you panic and empty your kitchen cabinets, consider the following points.
Linoleic acid is a type of omega-6 fatty acid found abundantly in soybean, sunflower, and corn oils. Since our bodies cannot produce this essential fat on their own, we must obtain it through food. This fatty acid plays a vital role in building healthy cell membranes, maintaining skin health, and regulating inflammation. Therefore, like many nutritional elements, it is both beneficial and potentially harmful depending on the amount and context of consumption.
Researchers at Weill Cornell Medicine in New York found that cooking oils rich in linoleic acid may carry risks. Linoleic acid can bind to a protein called FABP5, which is particularly present in triple-negative breast cancer cells. This interaction activates the mTORC1 pathway, a key regulator of cell growth, and when overstimulated, it can accelerate tumor progression.
They also observed that mice fed a diet high in linoleic acid developed significantly larger tumors. More concerning, high levels of FABP5 protein and linoleic acid were found in blood samples of women with triple-negative breast cancer, suggesting a possible biological connection.
The study suggests that linoleic acid may promote the growth of some cancers, but it does not claim that these oils directly cause breast cancer. Other factors such as genetics, overall diet, and environmental influences also play major roles.
In fact, a 2023 meta-analysis reviewing 14 studies and data from over 350,000 women found no significant effect of linoleic acid on breast cancer risk in the general population. Another study even suggested that it may have a protective effect, highlighting the importance of careful interpretation of research findings.
Organizations such as the World Cancer Research Fund emphasize that moderate consumption of vegetable oils is not dangerous, and that obesity—not specific fats—is the main dietary risk factor for cancer.
A 30-year Harvard University study tracking the health data of over 100,000 people found that diets rich in fruits, vegetables, whole grains, nuts, and low-fat dairy are associated with healthy aging. However, fewer than 10% of participants actually achieved what researchers defined as “healthy aging”—reaching age 70 without 11 major chronic diseases and with preserved cognitive, physical, and mental function. This shows that while isolated headlines about oils may draw attention, overall dietary patterns matter most in the long term.
The emerging link between linoleic acid and triple-negative breast cancer represents a step forward in understanding how diet may influence cancer development, but it also highlights the need for a balanced and precise approach to nutrition.
Modern Western diets tend to contain more omega-6 (such as linoleic acid) and less omega-3, and this imbalance may promote chronic inflammation, which is linked to many diseases, including cancer.
Balance and variety remain the foundations of a healthy diet. A balanced diet rich in whole, minimally processed foods remains the best option for reducing cancer risk and maintaining long-term health.
