Soft Drinks May Raise Odds for Respiratory Ills:
TUESDAY, Feb. 7 (HealthDay News) -- Drinking a lot of soft
drinks may increase the risk for asthma and/or chronic obstructive
pulmonary disease (COPD), a new study suggests.
Nearly 17,000 people aged 16 and older in South Australia were
asked about their consumption of soft drinks such as Coke, flavored
mineral water, lemonade, Powerade and Gatorade.
More than 10 percent of the participants said they drank more
than half a liter of soft drinks a day, according to the study,
published in the February issue of the journal
Respirology. That's a little more than two 8-ounce glasses of soft drinks.
The researchers found that 13.3 percent of the participants with
asthma and 15.6 percent of those with COPD consumed more than half
a liter of soft drinks a day.
People who consumed that amount were 1.2 times more likely to
have asthma and 1.7 times more likely to have COPD than those who
did not consume soft drinks, the researchers said.
"Our study emphasizes the importance of healthy eating and drinking in the prevention of chronic diseases like asthma and COPD," study leader Dr. Zumin Shi, of the University of Adelaide, said in a journal news release.
The researchers said the risk was dose-related, meaning the more
soft drinks consumed, the greater the odds of having COPD or
However, the study merely points out an association and does not
establish a cause-and-effect relationship.
Smoking increased the risk even further, especially for COPD.
People who smoked and consumed more than half a liter of soft
drinks a day had a 6.6 times greater risk of COPD than those who
didn't smoke and didn't consume soft drinks.
