Cinnamon

Cinnamon is one of the easiest spices to use in anti-inflammatory breakfasts and warm drinks. It helps create simple food patterns that are easy to repeat.

Quick answer

Cinnamon contains cinnamaldehyde, the compound responsible for its distinctive flavor, along with proanthocyanidins and other polyphenols. Ceylon cinnamon and cassia cinnamon differ significantly in their coumarin content, which is relevant for daily use.

What it is

Cinnamon is a spice from the inner bark of trees in the Cinnamomum genus. The two main types are Ceylon cinnamon (Cinnamomum verum, true cinnamon) and cassia cinnamon (Cinnamomum cassia), which is more common in supermarkets. It is available as sticks, ground powder, and extract.

Cinnamon has been used for thousands of years in traditional medicine and cooking across Asia, the Middle East, and Europe. It appears in Indian chai, Middle Eastern rice dishes, Mexican hot chocolate, Scandinavian baking, and American desserts.

Why cinnamon may support an anti-inflammatory diet

Cinnamaldehyde, which makes up 65-80% of cinnamon bark oil, has been studied for its ability to inhibit NF-kB activation and reduce production of pro-inflammatory mediators including nitric oxide and prostaglandin E2.

Cinnamon also contains type-A proanthocyanidins with antioxidant properties that may influence insulin signaling. The relationship between blood sugar regulation and inflammation is well-established, as chronic hyperglycemia promotes inflammatory pathways. Important: cassia cinnamon contains significant coumarin (up to 1% by weight), which can be hepatotoxic in large doses. Ceylon cinnamon contains only trace amounts and is safer for daily use.

Key nutrients and compounds

A 1 teaspoon (2.6g) serving of ground cinnamon provides approximately 1.4g fiber, 26mg calcium (2% DV), 0.2mg iron (1% DV), and 1.4mg manganese (60% DV). While individual servings are small, the polyphenol density is high. Cinnamon has one of the highest antioxidant capacities among common spices.

Potential health benefits

Contains cinnamaldehyde with studied anti-inflammatory and antimicrobial properties
May support blood sugar regulation linked to inflammatory control
Provides meaningful manganese even in small servings
Adds flavor complexity that can reduce reliance on added sugar

How to eat cinnamon

Add half a teaspoon to morning oatmeal or overnight oats
Stir into coffee or tea as a natural flavor enhancer
Sprinkle on sliced apples or bananas with nut butter
Use in savory dishes like Moroccan tagines or Indian curries
Mix into smoothies with banana, spinach, and almond milk
Make golden milk with turmeric, cinnamon, ginger, and warm plant milk

Shopping and storage

Choose Ceylon cinnamon for daily use to minimize coumarin intake. It is often labeled as 'true cinnamon' or 'Sri Lankan cinnamon.' Store ground cinnamon in an airtight container away from heat and light; replace every 6 months for best potency.

FAQ

Is Ceylon cinnamon better than cassia?

For daily use, Ceylon cinnamon is preferred because it contains much less coumarin, which can stress the liver in large amounts. Cassia is fine for occasional cooking but may not be ideal for daily supplemental use.

Can cinnamon help with blood sugar?

Some clinical trials have shown modest effects on fasting blood glucose, but results are inconsistent. Cinnamon may be a helpful addition to an overall blood sugar management strategy but should not replace medical treatment.

How much cinnamon is safe per day?

The European Food Safety Authority suggests a tolerable daily intake of 0.1mg coumarin per kg body weight. For cassia, this limits intake to about 0.5-1 teaspoon per day. Ceylon cinnamon can be consumed more liberally.

Does cinnamon lose potency over time?

Ground cinnamon gradually loses its volatile oils and flavor. For best potency, buy whole sticks and grind as needed, or replace ground cinnamon every 6 months.

Evidence note

Cinnamon has been studied in numerous clinical trials, primarily for blood glucose effects. A 2019 systematic review found that cinnamon supplementation was associated with reduced CRP levels, though study quality varied. Anti-inflammatory research is mostly preclinical.
