What are omega-3 fatty acids, and why are they good for your heart?
Omega-3 fatty acids are a type of unsaturated fatty acid that may reduce inflammation throughout the body. Inflammation in the body can damage your blood vessels and lead to heart disease and strokes.
Omega-3 fatty acids may benefit heart health by:
- Decreasing triglycerides
- Lowering blood pressure slightly
- Reducing blood clotting
- Decreasing your risk of strokes and heart failure risk
- Reducing irregular heartbeats
Eating at least two servings a week of fish, particularly fish that's rich in omega-3 fatty acids, appears to reduce the risk of heart disease, particularly sudden cardiac death.
