Cinnamon May Reduce Blood Glucose Levels

Cinnamon may reduce blood glucose levels, reports a new study.

In the recent study, adult participants under 30 years old were randomly assigned to receive plain breakfast cereal or breakfast cereal with six grams of ground cinnamon. Half of participants were of normal weight, and half were obese. Researchers measured blood glucose concentration every fifteen minutes after the breakfast cereal consumption, for two hours.

Data analysis showed that participants consuming cinnamon had significantly lower blood glucose at 15, 30, 45 and 60 minutes after cereal consumption. After two hours, the cinnamon group had a significantly higher blood glucose than the plain cereal group. However, the peak blood glucose in participants consuming cinnamon was much lower than that of the participants not consuming cinnamon. BMI did not affect blood glucose.

Researchers concluded that cinnamon may reduce the fluctuation of blood glucose after a meal. Further research on this topic is warranted.
