A large study from the New York Medical College and the University of Massachusetts found that high-fructose corn syrup (HFCS) is linked to a greater risk of asthma and chronic bronchitis. The research included 2,801 people between the ages of 20 and 55 years old.
The scientists utilized health data from the National Health and Nutrition Examination Survey of 2003 to 2006 to compare people with a history of chronic bronchitis.
The study measured the types of soft drinks consumed, eliminating risks related to known asthma relationships such as smoking. The researchers found those who drank five or more HFCScontaining sodas per week had an 80 percent increased incidence of chronic bronchitis. Greater intake of HFCS has also been linked with higher risk of other health conditions, including diabetes and obesity.
