Healthy eating and living can make a big difference when it comes to heart health. Mixing and matching a variety of these foods in your diet (in moderation) can be a great boost for cardiovascular health.
1. Oatmeal 
Oatmeal contains soluble fiber, which can lower cholesterol. However, when choosing a brand of oatmeal, try to avoid instant ones.
2. Berries
Berries contain phytonutrients and soluble fiber. Also, a recent study suggests that adding a few blueberries or strawberries in your yogurt may help reduce heart attack risk.
3. Fatty Fish like salmon, sardines, and mackerel
They contain great amounts of omega-3 fatty acids, which can lower the risk of arrhythmia (irregular heart beat) and atherosclerosis (plaque build-up in the arteries) and decrease triglycerides. Eating fish at least twice a week is recommended.
4. Healthy nuts such as almonds or walnuts
They contain fibers good for the heart. They also contain vitamin E, which helps lower bad cholesterol.
5. Dark chocolate 
Not only is it tasty, but several studies have now shown that dark chocolate may benefit your heart. Dark chocolate contains flavonoids which may help blood pressure, clotting, and inflammation.
6. Citrus fruits
Citrus fruits are also high in vitamin C, which has been linked with a lower risk of heart disease.
7. Legumes 
They are an excellent source of protein without a lot of unhealthy fat.
8. Tomatoes
Tomatoes contain lycopene, vitamin C and alpha- and beta-carotene.
