Higher habitual and lunch-specific carbohydrate quality index (CQI) is significantly associated with a reduced odds of low HDL cholesterol, but shows no significant association with metabolic syndrome or other MetS components.

Focus on the quality of carbohydrates you eat, particularly at lunch and throughout your habitual diet, to support healthy HDL cholesterol levels. This involves choosing foods with higher fiber, lower glycemic index, and fewer solid sugars. However, do not assume that high carbohydrate quality alone will prevent metabolic syndrome; you must also manage other factors like blood pressure, blood sugar, and waist circumference through comprehensive lifestyle changes.

ModerateQualifiesMEDIUM confidence
In habitual meal, before and after adjustment for the covariate, the odds ratio of low-HDL in third tertiles of CQI was significantly lower than the first tertiles [odds ratio (OR): 0.67; 95% CI: 0.47–0.96]. Moreover, within lunch meals, CQI is associated with low-HDL (OR: 0.66; 95% CI: 0.47–0.94) before and after adjustment for potential cofounding.

Why this rating

Cross-sectional design limits causal inference; however, the sample size (n=850) is robust and adjustments for covariates are extensive.
