Fig 2. Post-meal blood glucose peak rise and Δ_1hour of T2DM patients without or with raw cinnamon.

(A) Post-meal mean blood glucose peak rise (mg/dL) and (B) mean difference between 1-hour post-meal blood glucose and fasting blood glucose (Δ1hour) of T2DM men after eating a standardized meal alone (Control) or after prior ingestion of 3 g of raw cinnamon in capsules (3gCaps), 6 g of raw cinnamon in capsules (6gCaps), 3 g of raw cinnamon powder dissolved in water (3gPowder), or 6 g of raw cinnamon powder (6gPowder). The line at the value of +63 mg/dL (+3.5 mmol/L) indicates the maximum mean blood glucose rise achieved by healthy individuals after ingesting 50 g of carbohydrate from 27 tested foods [194]. *p ≤ 0.013 in relation to control.
