6 Side Effects Of Eating Too Much Cinnamon. Cinnamon is a spice made from the inner bark of the Cinnamomum tree. It is widely popular and has been linked to some impressive health benefits, including a lower risk of diabetes, cancer, and heart disease.
Here are 6 possible side effects of eating too much Cassia cinnamon
Although eating Cassia cinnamon is safe in small to moderate amounts, eating too much can cause health problems. This is because Cassia cinnamon contains high amounts of a compound called coumarin.
Research has found that eating too much coumarin can damage the liver and increase the risk of cancer. Also, eating too much Cassia cinnamon has been linked to many other side effects.
1. May cause liver damage
Cassia cinnamon or «regular» cinnamon is a very rich source of coumarin. It contains approximately 5 mg of coumarin per teaspoon (2 grams), while Ceylon cinnamon contains only small amounts of this compound.
The recommended daily limit for coumarin is approximately 0.05 mg / pound (0.1 mg / kg) of body weight, or 5 mg per day for a 130-pound (60 kg) person. This means that just one to one and a half teaspoons of Cassia cinnamon could exceed the daily limit.
Unfortunately, several studies have found that eating too much coumarin can cause toxicity and liver damage.
For example, a 73-year-old woman developed a sudden liver infection that caused liver damage after taking cinnamon supplements for just one week. However, this case involved supplements that provided a higher dose than you would get through diet alone.
