Arabinoxylan reduced glucose iAUC (SMD −0.41), insulin iAUC (SMD −0.28) and glucose and insulin peaks. Longer-term human benefit was limited to fasting glucose (MD −0.10 mmol/L); larger effects were seen in metabolically impaired people and with extracted arabinoxylan.

Isolated arabinoxylans lowered fasting glucose (SMD −0.19) and total cholesterol (MD −0.14) and raised lymphocyte count; food-intrinsic arabinoxylans lowered fasting glucose and systolic blood pressure (−2.86 mmHg).
