“…The possibility that altered respiratory variables after ingestion of carbohydrate were nonspecific and unrelated remote for the following reasons. The metabolic and respiratory responses to ingestion of carbohydrate confirm qualitatively and quantitatively to previous observations and predictions [38][39][40][41][42]. Consistent with previous reports [31,[43][44][45], a carbohydrate-rich diet is negatively associated with predicted FEV 1 , consistent with our result as well as another report with Korean women [46].…”

This study is aimed to examine the association between macronutrient intake and lung function in healthy adults (n = 5880) using the Ansan-Ansung cohort study. To identify the index of lung function, we used the percentage difference of predicted Forced Expiratory Volume (%FEV1_diff) between baseline and follow-up. Based on the median %FEV1_diff, subjects were classified by two groups as “decreased vs. unchanged/improved”. The dietary macronutrients were estimated and validated using the food-frequency questionnaire. Multiple logistic regression models were used to evaluate the association after adjusting for confounders. Advanced analysis examined the association after stratifying by age and obesity. The average of %FEV1 is 114.1 and 112.5 at baseline and follow-up, respectively. The positive association of protein and fiber intake with lung function was observed in men. Low fat and high carbohydrate intake decreased the lung function in women only. After stratification by age, the association of protein, fat, and carbohydrate intake with lung function was observed in young men and old women only. Otherwise, the association of protein and fiber with lung function was influenced by abdominal obesity. In conclusion, the lung function was positively associated with high protein and fat intake, but was negatively associated with high carbohydrate intake, which could be influenced by age and obesity.

“…Gas exchange was measured 30 minutes after 35 finishing the test drinks because (a) our preliminary studies showed that the peak Vco2 occurred around this time; (b) previous similar studies in normal subjects6 and patients with chronic obstructive lung disease4' used this protocol; (c) a previous study in cats showed that peak postprandial Paco2 occurred at this time12; and (d) the peak RQ after an oral sugar the load also occurs around 30 minutes postprandially. '3 14 The perceived effort to breathe (the Borg score) following a six minute walk also in-;e 6, creased more after the carbohydrate rich than hiree the fat rich load. The decrease in exercise 3%, tolerance and increase in Borg score both the correlated with the increase in Vco2 after the and carbohydrate rich load.…”
