Omega-3 fatty acids positively affect cardiovascular health by reducing inflammation, lowering blood pressure, and improving cholesterol levels. These essential fats, found in sources like fatty fish, flaxseeds, and walnuts, support heart function by promoting the health of blood vessels. Regular consumption of omega-3s is associated with a decreased risk of heart disease, stroke, and other cardiovascular conditions. Including these healthy fats in the diet contributes to overall heart health and well-being.
