The role of omega-3 fatty acids in heart health includes reducing inflammation, lowering triglyceride levels, and supporting vascular function. These essential fats, found in fatty fish, flaxseeds, and walnuts, contribute to the fluidity of cell membranes and improve endothelial function. Consuming adequate omega-3s has been linked to a lower risk of heart disease, stroke, and cardiovascular issues. Additionally, they can help regulate blood pressure and improve overall cholesterol profiles. Incorporating omega-3-rich foods into the diet is vital for promoting long-term heart health.
