Effect of daily fiber intake on luteinizing hormone levels in reproductive-aged women.

ABSTRACT:

Purpose

To evaluate whether the association between fiber intake and LH levels is driven by the association between fiber and estradiol, or whether there is an independent association.

Methods

A prospective cohort of 259 premenopausal women were followed for up to 2 menstrual cycles. Estrogen and LH were measured ≤8 times per cycle at visits scheduled using fertility monitors. Diet was assessed ≤4 times per cycle by 24-h recall. Linear mixed models on the log scale of hormones were utilized to evaluate the total effects of fiber intake. Inverse probability weights were utilized to estimate the independent effect of fiber on LH levels.

Results

In unweighted analyses, we observed a significant, inverse association between fiber intake (in 5 g/day increments) and log LH
