**What is the main health benefit of omega-3 fatty acids?**
The main health benefit of omega-3 fatty acids is their ability to support heart health. They help reduce levels of triglycerides, lower blood pressure, and decrease the risk of arrhythmias. Omega-3s also have anti-inflammatory properties, which can protect against chronic conditions such as rheumatoid arthritis and inflammatory diseases. Additionally, these fatty acids are vital for brain health, potentially reducing the risk of cognitive decline and supporting mental well-being. Incorporating omega-3-rich foods like fish, walnuts, and flaxseeds into the diet is beneficial.
