Imbalance of Omega-3 and -6 Can Increase Risk of Early Death

The consumption of healthy fats is good for overall health, but new research shows that an imbalance of types of fats can be harmful. "A high ratio of omega-6 to omega-3 fatty acids, as typical in the Western diet, contributes to many chronic diseases, including cardiovascular diseases, cancer, and autoimmune diseases," explained lead researcher Dr. Yuchen Zhang. Omega-3 fatty acids are found in nature in foods like fish, nuts, and seeds. They contribute to the health of the heart, lungs, immune system, and hormonal system. Foods rich in omega-6 fatty acids include seeds, nuts, corn, soy, and oils derived from these sources. Zhang and other researchers from the College of Public Health at the University of Georgia used data from 85,425 individuals. The researchers found that participants with the highest ratio of omega-6 to omega-3 fatty acids had a 26% higher risk of premature death. They also had a 31% higher risk of heart disease and a 14% higher risk of dying from cancer than participants with the lowest values. Participants with high levels of both omega-6 and omega-3 had a lower risk of early death. The authors pointed out that while omega-6 fatty acids are not harmful, excessive consumption can negate the anti-inflammatory effects of omega-3 fatty acids.
