The impact of Cinnamon on Blood Glucose Levels
In the quest for natural remedies to support our health, one spice has stood out in recent research – cinnamon. In this blog, we'll delve into the positive effects of cinnamon, particularly in lowering blood glucose levels.
Before we explore its benefits, let's deconstruct cinnamon by understanding the two main types: Ceylon or True Cinnamon, and Cassia.
Cinnamon is a spice obtained from the inner bark of several tree species from the genus Cinnamomum.
Cinnamon Types: Ceylon vs. Cassia
True Cinnamon (as known as Ceylon Cinnamon):
- Scientific name: Cinnamomum verum or Cinnamomum zeylanicum.
- Native to Sri Lanka
- Distinctive lighter, sweeter flavor.
- Prominent in blood glucose lowering research.
Cassia Cinnamon three or four varieties commercially used:
- Scientific name: Cinnamomum cassia, Cinnamomum loureirii (called Saigon Cinnamon), or Cinnamomum burmannii.
- Hails from China, Vietnam & Indonesia respectively
- All of which are similar in color (darker), aroma (robust), and spice level
- Recent studies are also exploring its potential health benefits
The Power of Cinnamon's Bioactive Compounds
Cinnamon, like other spices, is a store of valuable polyphenols and other bioactive compounds. One of the most important active ingredients in cinnamon is cinnamaldehyde.
It is believed to be responsible for most of cinnamon’s health benefits. Another crucial component is coumarin, an ingredient mostly found in Cassia Cinnamon which can cause liver problems.
Note: Cassia Cinnamon needs to be consumed in very large quantities to have any sort of negative effect. However, True Cinnamon has been historically preferred due to its low coumarin content.
Key Bioactive (Polyphenol) Compounds found in Cinnamon:
- Cinnamaldehyde: Identified as a potent active compound.
- Cinnamic Acids and Cinnamate: Beneficial polyphenols enriching cinnamon
Recent Study: The Impact of Cinnamon on Blood Glucose Levels
A recent study published in AJNC on Jan. 2024, particularly noteworthy, involved adults with pre-diabetes, employing a continuous glucose monitor for over four weeks.
Participants followed a low-fiber, low-polyphenol diet, and were assigned either a placebo or four grams (1 tsp.) per day of Indonesian cinnamon (Cinnamomum burmannii) powder.
The results were striking:
The cinnamon group showed lower glucose spikes after meals and overall more stable blood glucose levels compared to the placebo group.
Understanding the Results
The study utilized a continuous glucose monitor (CMG), providing a 24-hour live reading. The cinnamon group consistently outperformed the placebo group in maintaining stable glucose levels, showcasing the spice's potential in managing blood sugar. The dosage was 2 grams (½ tsp.) given twice daily with food.
Choosing the Right Cinnamon
Scientifically, the health benefits of cinnamon have been shown to significantly mitigate oxidative stress, inflammation, hyperglycemia, dysbiosis, and cholesterol levels.
While true cinnamon (Ceylon) has traditionally been the focus of research, recent studies are shedding light on the benefits of cassia cinnamon, especially the Indonesian variety. As science advances, further exploration will clarify any potential issues related to coumarin levels in cinnamon.
In conclusion, cinnamon, with its rich blend of bioactive compounds, presents itself as a promising natural ally in the journey to lower blood glucose levels.
Whether you opt for true cinnamon or explore the potential of cassia varieties, incorporating this flavourful spice into your routine may contribute to better glucose management and incidence of diabetes.
