Foods beneficial for heart health include those rich in omega-3 fatty acids, like salmon and walnuts, as well as fruits and vegetables high in antioxidants. Whole grains, such as oats and quinoa, help lower cholesterol levels, while legumes provide fiber and protein. Foods low in saturated fat, like lean proteins and healthy fats from sources like olive oil, are also vital. Incorporating these heart-healthy foods into daily meals can lower the risk of heart disease and improve overall cardiovascular health.
