Reduction of Inflammation and Autoimmune Diseases: Regular consumption of fish, especially fatty fish rich in omega-3 fatty acids (such as salmon, mackerel, and sardines), can help reduce inflammation in the body. Omega-3 fatty acids have anti-inflammatory properties that can benefit people with chronic inflammatory conditions and autoimmune diseases like rheumatoid arthritis. Studies have shown that omega-3s can help reduce the symptoms of these conditions, leading to better overall health and quality of life.
