(Newser) – People who drink more than one soda a day—even diet soda—face an increased risk of heart trouble, a new study has found. Consumption of  soda was linked to metabolic syndrome, a group of symptoms that  are risk factors for heart disease, in a new analysis of the 6,000 participants in the Framingham Heart Study.

In the four-year study published in tomorrow's issue of the journal Circulation, people who drank more than one soft drink of any kind a day were 44% more likely to develop metabolic syndrome than those who didn't drink any. Researchers aren't certain why. One theory is that soda drinkers are more prone to eat sugary, fattening food. Another is that soda ingredients may cause metabolic changes.
