Brush your teeth and you’ll cut your risk of heart disease, concludes a new study published in the British Medical Journal.

Researchers have long known that gum disease is associated with increased risk of heart problems. The link appears to be inflammation, which plays a role in the buildup of cholesterol in arteries. In this new study, published on the British Medical Journal’s website at BMJ.com, researchers examined whether the number of times people brush their teeth has any bearing on heart disease risk.

It does.

Anger and hostility can dramatically increase heart disease hazards, a new analysis of 38 studies shows. Most at risk: men.

Fructose-sweetened beverages appear to raise the level of fat particles in the blood called triglycerides, a well-documented risk factor for heart disease. That’s worrisome, because fructose consumption is also on the rise, surveys show.

Researchers don’t really know why we sleep. But they do know that sleep deprivation takes its toll. Recent insights add startling new reasons to get to bed early tonight.

Winter has settled in. The days are short. And medical experts worry that many of us may be falling short on a vitamin that’s far more important than anyone realized.

An international team of researchers reported this week that a substance measured in the blood, called high-sensitivity C-reactive protein, is a highly reliable early warning sign of heart disease.

That’s the guiding commandment of doctors. Shouldn’t the same apply to medications and other remedies, too? Of course it should. But new research has turned up a handful of remedies that may cause the very problem they’re supposed to treat.
