Heart disease is the number one killer of women in the United States.  We take a look at some ways you can help your heart.

The risk of developing heart disease increases with age, so doctors recommend getting an early start in protecting your hearts.

"If you're going to ward off heart disease in your 30s and 40s, you've got to start when you're in your 20s and start thinking about the things that you can do."

Cardiologist Bernadine Healy, former director of the National Institutes Of Health, has some basic tips to get started. "No smoking. I mean, that should not even be a consideration, even though 20 to 25 percent of women are smoking.

Number two: exercise. And although you can say, "I don't have time for it," it is something that's just got to be into your day.

And the third thing is having a healthy diet. It's so simple. You don't have to be Wolfgang Puck. You don't have to get special books to do it. Just a simple formula. Six to seven fruits and vegetables a day."

 And Healy also says... when it comes to helping your heart... it's never too early to get started.
