Quality versus Quantity- applies to coffee and to longevity

Coffee buzz: Java drinkers live longer, big study finds; regular and decaf are equally good | StarTribune.com: "One of life's simple pleasures just got a little sweeter. After years of waffling research on coffee and health, even some fear that java might raise the risk of heart disease, a big study finds the opposite: Coffee drinkers are a little more likely to live longer. Regular or decaf doesn't matter.

The study of 400,000 people is the largest ever done on the issue, and the results should reassure any coffee lovers who think it's a guilty pleasure that may do harm.

"Our study suggests that's really not the case," said lead researcher Neal Freedman of the National Cancer Institute. "There may actually be a modest benefit of coffee drinking.""
