20 Heart-Unhealthy Foods to Avoid Eating ASAP

4. French fries

Research has found that even a medium McDonald's french fry serving can put you at a higher risk of heart attack. Same as fried chicken, french fries often contain extra sugar and sodium to make them dangerously tasty, but they also soak up some of the fat from the oil they're cooked in. That oil likely contains trans fats. In addition, high levels of potato has been linked to increased risk for both hypertension and type 2 diabetes, which made French fries a one-two punch to your cardiac health.
