On the contrary, consuming high amounts of sugary drinks, such as apple juice, fruit drinks and soda, may be linked to the development of asthma in some people.
In a report published in the British Journal of Nutrition in May, researchers said consuming soda sweetened with high-fructose corn syrup, fruit drinks and apple juice two to four times a week led to a 59 percent greater chance of developing asthma.
Having these sugary drinks five to seven times per week led to an 89 percent higher chance of developing asthma, compared to those who seldom or never drank those drinks.
The study authors say the link may be because of the high glucose to fructose ratio in soda, certain juice drinks and even in 100 percent apple juice. They included diet soda and orange juice, which has a 1:1 ratio of glucose to fructose as comparison, and neither of those was associated with developing asthma.
The data analyzed was from the Framingham Offspring Cohort, a U.S. study group of more than 5,000 people with information that spans 30 years, starting in 1971. This cohort captures a timeframe before and after high-fructose corn syrup became the go-to sweetener.
