"Associated with" was the word used on CBS…"links" was the one NBC deployed. Thus the networks' in-house physicians, Jon LaPook and Nancy Snyderman, tried to dial back the headlines from their anchors. On NBC, Brian Williams announced: "This one is about soft drinks and heart disease." From CBS' Katie Couric warned that soft drinks "may be bad for our hearts." Well not quite. "Experts caution that today's study does not show cause and effect," Snyderman insisted. "It is not cause and effect," declared LaPook.
A sober Snyderman explained that the condition dubbed "metabolic syndrome" represents a cluster of risk factors for heart disease or diabetes such as increased waist size, high blood pressure, elevated triglycerides, lowered HDL cholesterol, high blood glucose. The study analyzed individuals diagnosed with the syndrome and those who drink more than a single soft drink a day--either soda or cola, regular or diet. It found that the two groups are more likely to overlap than not. This led LaPook to ask the "one big question. Does diet soda contribute to metabolic syndrome? Or are the people drinking it just more likely to engage in unhealthy behavior?"
