Abstract: Background— The quality and quantity of dietary carbohydrate intake measured as dietary glycemic load (GL) is associated with a number of cardiovascular disease (CVD) risk factors and in healthy young women is related to increased high sensitivity C-reactive protein (hsCRP) concentrations. Our objective was to determine if GL is related to hsCRP and other measures of CVD risk in a population of sedentary overweight dyslipidemic middle-aged women and men enrolled in an exercise intervention trial (STRRIDE). ethods— This was a cross-sectional evaluation of the relationships between measures of dietary carbohydrate intake calculated from food frequency questionnaire data and CVD risk factors including plasma hsCRP measured in 171 subjects. esults— After adjusting for energy intake GL and other measures of carbohydrate intake were not independently related to hsCRP (P>0.05 for all). In analyses performed separately for each gender only the quantity of carbohydrate intake was independently related to hsCRP (R2=0.28; P<0.04) and this relationship was present for women but not for men. The strongest relationship identified between GL and any CVD risk factor was for cardiorespiratory fitness (R2=0.12; P<0.02); an elevated GL was associated with a lower level of fitness in all subjects and this relationship persisted even when the findings were adjusted for energy intake and gender (R2=0.48; P<0.03). onclusions— In middle-aged sedentary overweight to mildly obese dyslipidemic individuals consuming a diet with a low GL is associated with better cardiorespiratory fitness. Our findings suggest that the current literature relating carbohydrate intake and hsCRP should be viewed with skepticism especially in the extension to at-risk populations that include men.
