Although this might seem like an obvious statement, recent research has convinced some people that compounds in chocolate are good for the heart.
However, the British Heart Foundation notes that in other ways, chocolate is an unhealthy product and that people should therefore not turn to chocolate to help them live longer.
Cardiac nurse Ellen Mason said: "Research has shown that certain chemicals in cocoa may have some benefits for our circulation.
"But it is important to remember that chocolate is more often part of the problem for heart health rather than the solution."
Ms Mason added that eating five portions of fruits and vegetables every day is "a far better way" to get antioxidants than chocolate.
People can also reduce their risk of heart disease by exercising regularly, maintaining a healthy weight, reducing their intake of salt and saturated fat, and giving up smoking.
