The Core Concern: Coumarin in Cassia Cinnamon
For a breastfeeding mother, every food choice is important as components can pass through breast milk to the baby. The primary concern with cinnamon lies with coumarin, a naturally occurring chemical compound found in certain cinnamon varieties. Research has shown that large amounts of coumarin can be hepatotoxic, meaning it can cause liver damage. The amount of coumarin varies drastically between the two main types of cinnamon: Cassia and Ceylon.
Cassia cinnamon, which is the most widely available and cheapest type found in most grocery stores across North America, is the one with high levels of coumarin. While consuming typical food amounts (like a sprinkle on toast) is generally not an issue for most adults, larger or more frequent intake can be problematic for sensitive individuals. This is particularly relevant for nursing mothers, as an infant's developing liver may be more vulnerable to coumarin's effects. This is a major reason why avoidance, particularly of supplements or large doses, is a key consideration for maternal nutrition.
Cassia vs. Ceylon: The Crucial Difference
Not all cinnamon is created equal. Understanding the difference between Cassia and Ceylon is essential for any breastfeeding mother. The contrast in coumarin levels is the most significant factor in a breastfeeding diet.
| Feature | Cassia Cinnamon | Ceylon Cinnamon |
|---|---|---|
| Commonality | Most common, widely sold in stores | Less common, often labeled as "true cinnamon" |
| Coumarin Content | High levels, potential liver risk with high intake | Trace amounts, considered much safer |
| Appearance | Thicker, rougher sticks; darker color | Thinner, more brittle, and softer sticks; lighter brown color |
| Flavor | Stronger, spicier flavor | Milder, sweeter, and more complex flavor |
| Safety During Lactation | Use caution with large amounts or supplements | Generally safer in moderate, food-level amounts |
For mothers who wish to continue enjoying cinnamon, choosing Ceylon over Cassia is the safest option. It minimizes exposure to coumarin, offering peace of mind while adding flavor to foods. It is important to note that even with Ceylon, moderation is key, and supplements should always be avoided due to a lack of safety data during lactation.
Potential Side Effects in Infants
Even with Ceylon cinnamon, some babies can have a reaction to spices transmitted through breast milk. The effects are typically not severe but can be uncomfortable for the infant. The transfer of flavors and compounds can alter the breast milk's taste and potentially affect the baby's digestive system. Some common signs of an infant reacting to something in a mother's diet can include:
- Gastrointestinal upset, leading to fussiness, gas, or colic-like symptoms.
- Changes in stool, such as diarrhea.
- Skin irritation, including rashes or hives, although this is less common with ingested cinnamon.
- Restlessness or agitation, similar to the effects of caffeine.
Since every baby is unique, mothers should monitor their infant for any changes in behavior or digestion after consuming a new food or spice. If a reaction is suspected, temporarily removing the food from the diet can help determine if it was the cause.
The Lack of Specific Research
The primary reason for caution with cinnamon and breastfeeding is the scarcity of reliable research on its effects. While it has been traditionally used in some cultures, there is a distinct lack of modern scientific studies specifically assessing the safety and impact of cinnamon supplements and high doses on nursing mothers and their infants. This absence of data means that any potential risks, particularly long-term effects on infant development, are not fully understood. Without established safe intake levels for lactation, healthcare providers and health organizations often recommend erring on the side of caution. This is especially true for concentrated supplement forms, which contain far higher levels of active compounds than typical food portions.
How to Safely Enjoy Cinnamon in Your Diet
For mothers who love the flavor of cinnamon, a complete ban is likely unnecessary. The key is to be mindful of the type and amount. Here are some strategies for including cinnamon safely in a breastfeeding diet:
- Choose Ceylon Cinnamon: Opt for products specifically labeled "Ceylon" or "true" cinnamon. It is widely available online and in health food stores.
- Stick to Food Amounts: Use cinnamon as a spice, not a supplement. The small amounts used in baking, oatmeal, or sprinkled on fruits are generally considered safe.
- Introduce Spices Gradually: If you haven't consumed cinnamon in a while, add it back into your diet slowly. This makes it easier to pinpoint if it causes any adverse reactions in your baby.
- Monitor Your Baby: Watch for any signs of discomfort or changes in your baby's feeding patterns, sleep, or skin after you consume cinnamon. If you notice a consistent reaction, consider avoiding it for a week to see if symptoms improve.
- Read Labels Carefully: Be aware that many products and supplements simply list "cinnamon" without specifying the type. Without confirmation, it is safest to assume it is the higher-coumarin Cassia variety.
Conclusion
While a sprinkle of cinnamon on your morning oatmeal is unlikely to cause harm, understanding why avoid cinnamon while breastfeeding, especially in large quantities, is crucial for maternal health. The risk is primarily associated with the high coumarin content found in Cassia cinnamon, which can potentially affect an infant's developing liver. By choosing the safer Ceylon variety and sticking to culinary amounts, you can mitigate this risk. In the absence of extensive scientific research, avoiding supplements during lactation is the most prudent approach. Always prioritize communication with a healthcare professional regarding any dietary changes during breastfeeding.
