According to the diet doc [Arthur Agatston of South Beach Diet fame], studies show that high concentrations of cocoa found in dark chocolate -- at least 70 percent -- help improve vascular function by relaxing blood vessels, keeping cholesterol from gathering in blood vessels and reducing the risk of blood clots.
Others agreed. Jeffrey Blumberg, a professor of nutrition at Tufts University's Friedman School of Nutrition, in Boston, said dark chocolate contains flavanols, plant-based antioxidants that may have beneficial effects on cardiovascular function. These benefits might extend to improving heart function and lowering blood pressure, he said.
"However, even if you're eating 80 percent cocoa, flavanol-rich dark chocolate, you're still eating a high-calorie, high-fat food," the Boston expert warned. "It is not a 'health food.'"
Nevertheless, he and a team of researchers published a study last August in Hypertension that found that eating a dark chocolate candy bar once a day for 15 days significantly lowered the blood pressure of 20 people suffering from hypertension.
There was a catch: The participants had to lower their caloric intake of other foods to accommodate the nearly 500 calories they consumed every day by eating the candy bar.
"You choose whole grain bread instead of white bread, sweet potatoes instead of white potatoes, and when it comes to Valentine's Day, choose dark chocolate-covered almonds rather than milk chocolate or white chocolate," Agatston said.
"You want to make the best choices, even when you're cheating a bit," Agatston advised.

I've been trying to convince myself of this lately also, but I just can't help but think it's like eating a piece of fried chicken. It may be fried, but it's chicken, chicken is good for you.
