Scientists have reported the effects of soda water on asthma
Preschoolers who consume a large amount of sweet sparkling water are much more likely to suffer from asthma and related complications while studying at school than their peers who eat healthy, say scientists in the Annals of the American Thoracic Society .
"In the past, our colleagues have already uncovered the link between drinking and asthma in schoolchildren, but no one has tried to test how early-age fructose can affect children's health in the coming years. Our research shows that rejection from drinking sparkling water in the first years of life and even during pregnancy can protect a baby from developing asthma, "said Sheryl Rifas-Shiman of Harvard University (USA).
Asthma is a chronic inflammation of the respiratory system, which is expressed in attacks of shortness of breath of varying strength and duration. They occur due to impaired immune cells that cause inflammation in the respiratory passages and cause them to narrow.
The World Health Organization estimates that as many as 300 million people are suffering from asthma today, and every decade the number of patients is increasing by half.
These disorders in the work of immune cells, as noted by Rifas-Shiman, can develop for various reasons - as a result of insufficient contact of children with germs and fungi, which "teach" the immune signal "own-stranger", as well as through the development of chronic inflammation, obesity, and various disorders in metabolism and signaling molecules.
Harvard physicians have found that such disorders can affect the likelihood of developing asthma in a baby long before he or she is first born and attending school, observing the health of the thousands of pregnant women who have agreed to participate in the research by Rifas-Shiman and her colleagues.
Scientists have comprehensively studied the health of mothers and their future children, analyzing the composition of their blood, susceptibility to asthma and other diseases, diet and many other aspects of their lives. Three years later, they re-examined the number of asthma victims, and five years later summarized the findings.
Comparing the various risk factors and the number of children suffering from asthma, Harvard researchers sought to understand which of them most strongly influenced the likelihood of its acquisition.
As it turned out, the use of soda water significantly increased the chances of developing asthma until 8-9 years of age, even if it was not drunk by the child, but his mother during fetal birth. According to the researchers, the children of such parents were 63% more likely to suffer from asthma when entering school than other preschoolers.
A similar situation was typical of the consumption of sugary drinks by the children themselves - the likelihood of developing asthma increased by 64%, even if their mothers behaved responsibly and did not drink soda during pregnancy.
The presence of such a link between sweets and asthma, according to Rifas-Shiman, suggests that fructose can cause immune cells to attack the lungs per se, and not only indirectly, as a result of the development of obesity and the appearance of inflammation in other parts of the body.
For this reason, limiting the use of soda and sugar by children, scientists say, may be one of the most effective methods of controlling asthma in the United States and other countries, characterized by both high levels of obesity and the consumption of sugary drinks.
