4. Fatty fish
Fatty fish, especially salmon and mackerel, provide long-chain omega-3 fatty acids. Omega-3s are directly connected to improved heart health since they increase HDL cholesterol. They also lower stroke risk and inflammation. The healthiest ways to consume fish in your diet are baked, broiled, grilled or raw. On the other hand, fried fish could build the risk of heart disease and stroke, so it is best to avoid it. Since fish is a major part of the Mediterranean diet, it has been studied to a large extent for its health benefits for the heart. Some of the benefits of fish that protect the heart are derived from certain peptides found in fish protein.
