Essential fatty acids contribute to heart health by promoting a balanced lipid profile and reducing inflammation. Omega-3 fatty acids, found in fish and flaxseeds, can lower triglycerides and blood pressure while improving endothelial function. They also play a role in preventing the buildup of plaque in the arteries, reducing the risk of heart disease. Incorporating dietary sources of essential fatty acids into daily meals can enhance cardiovascular health and overall well-being.
