Sugar-sweetened beverages are linked to poor health outcomes such as heart disease and stroke. Researchers in Australia have recently found that sugary drinks are associated with an increased risk of asthma and chronic obstructive pulmonary disease (COPD). Though this cross-sectional study does not prove that sodas are the cause of these problems, it does offer some interesting results. Those who drank at least half a liter per day were twice as likely to develop either lung condition (OR 2.33, 95% CI 1.51 to 3.60) compared to those who drank none. Those who drank soda and smoked showed a 6.6 fold increase in risk.
