INS and Insulin resistance: Overall, higher dietary fiber intake was significantly associated with reductions in parameters involving glycemic control, including fasting plasma glucose (ES = -0.55, 95% CI: -0.73, -0.38, <i>P</i> < 0.001), fasting plasma insulin (ES = -1.22, 95% CI: -1.63, -0.82, <i>P</i> < 0.001), homeostasis model assessment of insulin resistance (HOMA-IR) (ES = -0.43, 95% CI: -0.60, -0.27, <i>P</i> < 0.001), and glycosylated hemoglobin (HbA1c) (ES = -0.38, 95% CI: -0.50, -0.26, <i>P</i> < 0.001).
