Key finding
The intake of raw cinnamon dissolved in water decreased the meal-induced large glucose spike (Δ1-hour glycemia of +79 mg/dL).
This study investigated the acute effects of raw cinnamon on post-meal glucose spikes in type 2 diabetes patients, finding that cinnamon in water reduced glucose spikes while capsules did not.

Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study investigated the acute effects of raw cinnamon on post-meal glucose spikes in type 2 diabetes patients, finding that cinnamon in water reduced glucose spikes while capsules did not.
Managing postprandial blood glucose levels is crucial for individuals with type 2 diabetes to prevent complications. This study suggests that incorporating raw cinnamon into meals may offer a simple dietary strategy to help control blood sugar levels, though the form of cinnamon matters.
Unclear effectiveness of interventions due to lack of statistical significance. Limited generalizability due to specific participant characteristics. Potential confounding factors not accounted for in the study design.

Cinnamon dissolved in water decreased postprandial blood glucose by 79 mg/dL.
Cinnamon intake flattened the glycemic curve, leading to a lower iAUC.
Cinnamon capsules did not show significant anti-hyperglycemic effects.
The control group exhibited typical postprandial hyperglycemia.
