Cinnamon: What Effects Does It Have on Blood Sugar and Weight Management?

Cinnamon has long been appreciated for its warm flavor, but also for the various effects attributed to it regarding dietary balance and digestive comfort. Several studies have also examined its potential impact on certain factors involved in weight management, such as blood sugar levels, oxidative stress, and digestion. Although the results remain nuanced, cinnamon is currently generating significant interest in the field of nutrition.

Cinnamon and blood sugar balance

Blood sugar levels play an important role in energy balance and daily feelings of hunger. A study conducted in people with type 2 diabetes found that daily consumption of cinnamon for 40 days was associated with a decrease in fasting blood sugar. (2) Certain compounds in cinnamon, particularly its polyphenols, are currently being studied for their interaction with insulin sensitivity and glucose metabolism.

The Digestive Benefits of Cinnamon

The World Health Organization (WHO) notes the traditional use of cinnamon bark to alleviate certain mild digestive discomforts, such as bloating, flatulence, or mild gastrointestinal spasms. (4) Cinnamon is also traditionally used after meals for its comforting taste and its benefits for digestive comfort.

Cinnamon and Oxidative Stress

Rich in polyphenols, cinnamon is studied for its antioxidant properties and its potential in combating oxidative stress. (3) Oxidative stress refers to an imbalance between the production of free radicals and the body’s defense mechanisms. When it becomes excessive, it can disrupt proper cellular function and contribute to various imbalances in the body.

Cinnamon and Weight Management

A meta-analysis combining 21 randomized controlled trials and 1,480 participants observed a modest reduction in body weight, BMI, and waist-to-hip ratio among individuals supplemented with cinnamon. The authors note, however, that further studies are needed to confirm these results. (5) Cinnamon is therefore not a solution on its own, but can be incorporated into a balanced diet and a healthy lifestyle overall.
