NEW HAVEN, June 4 — A study from Yale School of Medicine suggests that the type of fat in the diet, not just the amount, could influence the risk of pancreatic cancer, one of the deadliest cancers.
The researchers tested high-fat diets in mice genetically prone to pancreatic ductal adenocarcinoma, keeping calories the same and varying only the fat source. The study found that oleic acid, the main fat in olive oil and long considered heart-healthy, significantly accelerated tumor growth.
On the other hand, omega-3-rich fats from fish oil cut disease development roughly in half.
The proposed mechanism involves ferroptosis, a form of cell death triggered by lipid oxidation: monounsaturated fats resist oxidation and may shield cancer cells, while polyunsaturated omega-3s oxidize easily and push malignant cells toward death. A key finding of the study is that the effect was pronounced in male mice but largely absent in females. The work, published in Cancer Discovery, has not been replicated in humans and does not mean people should avoid olive oil.
Patients should consult their doctor for personalized advice on diet and nutrition. As research continues to uncover the complex relationships between diet and disease, studies like this one offer hope for a better understanding of how to prevent and treat pancreatic cancer.
The fact that certain types of fat may influence the risk of this deadly disease is a significant finding, and further research is needed to fully understand the implications of this finding.
Looking ahead, it will be important to watch for further studies that build on this research and explore the potential benefits and risks of different types of fat in the diet. By continuing to advance our understanding of the relationships between diet, nutrition, and disease, we can work towards a future where pancreatic cancer is more preventable and treatable.
