Background:<\/strong><\/p>\n\n- There is growing evidence that intakes of high-fructose corn syrup (HFCS), HFCS-sweetened soda, fruit drinks and apple juice \u2013 a high-fructose 100% juice \u2013 are associated with asthma.<\/li>\n
- It is possible that this is due to the high fructose: glucose ratios and underlying fructose malabsorption which may contribute to enteral formation of pro-inflammatory advanced glycation end products, which bind receptors that are mediators of asthma.<\/li>\n
- Though there is a large amount of research in this area, epidemiological studies with longitudinal data are lacking.<\/li>\n<\/ul>\n
Methods:<\/strong><\/p>\n\n- Survival analysis was conducted with longitudinal data from the Framingham Heart Study-Offspring cohort (FHS-OS). Participants were adult, predominantly non-Hispanic White men and women, with a mean age of 47.9 years. Thirty-nine percent were overweight and 17% were obese at baseline.<\/li>\n
- Participants were medically examined and responded to health questions approximately every 4 years, with the exception of an 8-year gap between examinations 1 and 2. Food and beverage intake frequency was obtained via the Willett Food Frequency Questionnaire (FFQ), beginning with the third examination.<\/li>\n
- The current study focused on data examinations 3-7, between the years 1984-2001.\u00a0 There were between 2692 and 2696 participants with complete responses to analyses questions, depending upon the beverage.<\/li>\n
- The Intake frequency of non-diet soda, fruit drinks, apple juice and any combination of these beverages as self-reported at each examination via the Willett FFQ was analyzed. Incident asthma, defined as self-reported asthma, including wheezing or asthma since the previous examination of short or long duration, or with respiratory infections, was also analyzed.<\/li>\n<\/ul>\n
Findings:<\/strong><\/p>\n\n- Increased consumption of all sugar-containing beverages was associated with higher total energy intakes.<\/li>\n
- \u00a0Greater intake of any combination of HFCS-sweetened soda, fruit drinks and apple juice was significantly associated with progressively higher asthma risk, rising from 59% higher for moderate (2\u20134 times\/week) consumers to a plateau of 89% higher among 5\u20137 times\/week as compared to never\/seldom consumers, independent of potential confounders including age, sex, BMI, smoking, education level and total energy intake.<\/li>\n
- Regular (5\u20137 times\/week) consumers of HFCS-sweetened soda had a 48% higher asthma risk compared with never\/seldom consumers, independent of potential confounders.<\/li>\n
- Moderate consumers (2\u20134 times\/week) of fruit drinks had 58% higher asthma risk and moderate consumers of apple juice had 61% higher asthma risk, compared with never\/seldom consumers, independent of sex, age, smoking history, education level, BMI and total energy intake.\u00a0 There was no association between diet soda or orange juice intake and asthma.<\/li>\n<\/ul>\n
Conclusions:<\/strong><\/p>\n\n- Moderate and frequent consumption of HFCS-sweetened soda, fruit drinks and apple juice, but not diet soda or orange juice, increased asthma risk, independent of age, sex, smoking, BMI, education level, total energy intake and T2D.<\/li>\n
- Recommendations to reduce sugar-sweetened beverage consumption may be inadequate to address asthma risk, as associations are evident even with moderate intake of apple juice \u2013 a 100% juice.<\/li>\n
- Intervention studies and more research of consequences of fructose malabsorption are needed.<\/li>\n<\/ul>\n
Points to Consider:<\/strong><\/p>\n\n- Outcomes were based on self-report, which is subject to reporting bias.<\/li>\n
- A myriad of foods contribute to fructose and HFCS intake (cold cereals, breads, snack bars, desserts, sweets, ketchup, sauces, etc), which were not accounted for in this study.<\/li>\n
- This study is not nationally representative. Participants were mainly non-Hispanic white Americans, which does not allow consideration of race\/ethnicity on this relationship.<\/li>\n
- Income and occupational\/environmental air quality, possible confounders, were not accounted for in this study.<\/li>\n<\/ul>\n
