Soft drinks 'increase asthma risk'
A link between asthma and high levels of soft drink consumption has been suggested by researchers in Australia.
The team at the University of Adelaide, led by Zumin Shi, said that the amount of soft drink consumed is associated with an increased chance of asthma and/or chronic obstructive pulmonary disease (COPD).
The research further emphasises the importance of healthy eating and drinking in a bid to reduce the chances of developing such chronic diseases.
The results, published in the journal Respirology, show that of the almost 17,000 participants in the study some 13.3% with asthma and 15.6% with COPD reported consuming more than half a litre of soft drink on a daily basis. For this study, soft drinks included Coke, lemonade, flavoured mineral water and Powerade.
The odds ratio for asthma and COPD was 1.26 and 1.79, comparing those who consumed more than half a litre of soft drink per day with those who did not consume soft drinks.
The study’s authors also stated that the link become more pronounced if those drinking a high level of soft drinks also smoked, with figures suggesting a 6.6-fold greater risk of developing COPD.
