Omega-6 fatty acids are essential for health as they play a critical role in the body's inflammatory response, brain function, and metabolism. They are crucial for cell membrane structure and are involved in the production of important hormones. However, the typical Western diet may contain excessive amounts of omega-6s relative to omega-3 fatty acids, potentially leading to chronic inflammation and associated health issues. Balancing omega-6 intake with omega-3s is essential for optimal health.
