DEAR DOCTOR K: I've heard that coffee is good for your health -- but I've also heard that it increases your blood pressure and heart rate. What's true?
DEAR READER: Right now, the evidence I'm aware of points to health benefits for most people from regularly drinking coffee. I'm talking about straight coffee -- minus the cream and sugar. Straight coffee is a nearly calorie-free beverage brimming with antioxidants. There's evidence that drinking coffee might help prevent Type 2 diabetes and reduce the risk of heart disease and stroke. And studies show lower rates of gout and liver disease among regular coffee drinkers.
