Macro partitioning
In Chinese females, higher total carbohydrate consumption (particularly from refined grains) is associated with increased systolic and diastolic blood pressure, with the strongest adverse effects observed at higher blood pressure quantiles.
For Chinese females, reducing refined carbohydrate intake (white rice, white bread) to approximately 130-150g per day may help optimize blood pressure, especially if you already have elevated readings. Men in this population did not show the same association, suggesting gender-specific dietary strategies may be necessary.
In females, increased total carbohydrates intake was associated with adverse SBP and DBP... Both relatively low and high carbohydrate intake were associated with increased SBP, with minimum level observed at 130–150 g carbohydrate intake per day... However, no significant associations were observed in males.
Why this rating
Cross-sectional design limits causal inference; however, the sample size is large and adjustments for confounders are extensive.
