The primary role of omega-3 fatty acids in health is to support cardiovascular function and reduce inflammation. These essential fats, found in fish, flaxseeds, and walnuts, contribute to heart health by lowering triglyceride levels, reducing blood clotting, and improving overall lipid profiles. Omega-3 fatty acids are also beneficial for brain health, promoting cognitive function and potentially reducing the risk of neurodegenerative diseases. Their anti-inflammatory properties can help manage conditions such as arthritis and other inflammatory disorders, making them a critical component of a balanced diet.
