Omega-3 and Omega-6 May Reduce the Risk of 14 Types of Cancer

New research published in the "International Journal of Cancer" indicates that the consumption of omega-3 and omega-6 fatty acids may influence the reduction of cancer risk. These findings encompass 14 different types of cancer, including colorectal, stomach, lung, brain, bladder, and others. Dr. Kaishiong Yeh from the Department of Genetics at the University of Georgia and the lead author of the study states, "These findings confirm previous reports that highlighted the benefits of omega-3 and omega-6 fatty acids in reducing cancer incidence and mortality." Omega-3 and omega-6 fatty acids are two types of unsaturated fatty acids that contain multiple carbon double bonds in their chemical chain. Despite their significant similarities in chemical structure and biological pathways, these two types of fats have unique effects on health. According to Dr. Yeh, "Omega-3s play a larger role in brain development, cognitive function, and cardiovascular health, while omega-6s are effective in immune function and skin health." This new study focused on over 250,000 individuals registered in the UK Biobank. This biomedical database project has been running since 2006 and provides valuable data across various medical and health fields. The research showed that during the study period of approximately 13 years, about 30,000 participants developed one of 19 types of localized cancer. The studies indicated that higher levels of omega-3 and omega-6 in the blood are associated with a reduced risk of several cancers. Specifically, high levels of omega-3s were linked to a lower risk of colorectal, stomach, and lung cancers, while high levels of omega-6s were associated with a lower likelihood of brain, bladder, kidney, thyroid, and other cancers. However, maintaining a balance between omega-3 and omega-6 in the body is crucial for cancer prevention and other public health conditions. Taylor Yanolovich, a nutritionist, told the "Health" website, "This study shows that while higher levels of omega-6 and omega-3 in the blood are associated with reduced cancer risk, a higher omega-6 to omega-3 ratio increases cancer risk." Yanolovich also recommends that if you want to add more unsaturated fats to your diet, it is better to start with foods such as salmon, walnuts, chia seeds, and flaxseeds. She added, "Whole foods help the body absorb these nutrients more effectively than dietary supplements."
