If you're still drinking soda, there's not much else I can say at this point. You don't have to be a regular Dose reader to know this stuff is bad for you, and you'd have to have a hole in your head to think it's actually good.

Hopefully, your head is intact and you know it's bad. And now, a new study spells out just ONE of the many ways soda can doom you to an early, bubbly grave.

In this one, researchers found that men who have even one soda or other sugar-sweetened drink a day have a 20 percent higher risk of a heart attack than those who don't drink this liquid junk.

Two daily drinks boosted the risk by 42 percent, and three caused it to shoot up by 69 percent.

Sugary drinks also boosted levels of C-reactive protein, an inflammation marker that's a far more reliable indicator of heart risk than the LDL levels your own doc obsesses over.

The study in Circulation was on men, but there's no reason to think it won't apply to women as well. After all, you don't have to be a cardiologist to know why soda will stop your heart.

It's the sugar.

Sugar is just about the worst thing you could pump into your body. And after your teeth, there's no part of your body that's more quickly ruined by it than your heart. Drink this stuff every day, and eventually it'll stop your heart colder than a refrigerator pack of cola.

Throw in the fact that soda -- and sugar -- will swell your belly, rot your brain, and even damage your bones, and you've got no reason to ever go near this stuff.

I know some of you will anyway. Just don't say I didn't warn you.
