Tomatoes
Not only do tomatoes have heart-healthy potassium, they also contain lycopene—a compound that acts as a cardio-protective and anti-inflammatory to improve blood flow while reducing blood pressure. Lycopene also binds to LDL cholesterol, which may help protect against atherosclerosis (hardening of the arteries) by suppressing the lipid from damaging blood vessels.
Tuna
Whether you prefer fresh or canned, one thing is certain: Tuna is a heart-healthy superstar. Fatty fish such as tuna contain lots of omega-3s, fatty acids the American Heart Association recommends to help reduce inflammation, lower blood pressure and triglycerides, and reduce your risk for heart disease. Aim for at least two servings per week (about six ounces cooked).
