Abstract
Purpose
This paper aims to evaluate the association between carbohydrate quality index (CQI) and nutrient adequacy in Iranian adults.
Design/methodology/approach
A total of 268 men and women with ages ranged from 18 to 70 years were evaluated in a cross-sectional study. The CQI was calculated by adding together the three components, namely, the ratio of solid to total carbohydrate, dietary fiber and glycemic index. The scores of three components were summed to calculate the CQI, with a higher score indicating a higher dietary carbohydrate quality. The odds ratios (ORs) of nutrient adequacy ratio (NAR), defined as the ratio of intake of a nutrient to the age- and gender-specific recommended dietary allowance, for the intake of energy and 10 nutrients across quartiles of the CQI were calculated by logistic regression analysis and expressed with 95% confidence intervals (CIs).
Findings
CQI ranged between 3 to 15 (mean ± SD: 9 ± 1.9). Being in top versus bottom quartile of the CQI was associated with a higher NAR of folic acid (OR: 3.20, 95% CI: 1.06–9.62; P-trend: <0.001), vitamin A (OR: 3.66; 95% CI: 1.46–9.17; P-trend: <0.001), magnesium (OR: 5.94; 95% CI; 1.71–20.53; P-trend: <0.001), vitamin C (OR: 7.85; 95% CI; 2.99–20.59; P-trend: <0.001).
Originality/value
A higher CQI was associated with greater micronutrient consumption adequacy in Iranian adults. The results suggest that increasing the consumption of total fiber and solid carbohydrates and decreasing the glycemic index of the diet and liquid carbohydrates can improve micronutrient intake adequacy.
