Based on the available information, both diet and aspirin can play a role in promoting heart health, but they function in different ways.

Aspirin is known for its blood-thinning properties, which can help prevent blood clots from forming and potentially causing heart attacks or strokes [1]. However, it's important to note that aspirin therapy should be used under a doctor's recommendation, as it's not suitable for everyone and can have side effects [1].

On the other hand, a heart-healthy diet can significantly reduce the risk of cardiovascular disease (CVD) [2]. The Harvard T.H. Chan School of Public Health notes that a diet rich in fruits, vegetables, whole grains, and healthy fats can help lower cholesterol, blood pressure, and inflammation [2]. This is achieved by providing the body with essential nutrients, fiber, and antioxidants that support overall heart health [2].

In summary, while aspirin can help prevent blood clots, a heart-healthy diet addresses multiple risk factors for CVD by lowering cholesterol, blood pressure, and inflammation [1][2]. It's crucial to consult with a healthcare professional to determine the best course of action for individual heart health needs.
