Eating one of the tastiest household spices may also improve learning ability, memory and even reverse Parkinson's Disease according to new study results published online in the Journal of Neuroimmune Pharmacology.
Cinnamon is one of the most potent antioxidants in the world and . regular consumption can lower blood sugar, help digestion, ease arthritis, lower blood pressure and even ward off Alzheimer’s. If you are to maximize the medicinal value of cinnamon it must also be non-irradiated and pure ceylon which will be labeled as such.
Which Type Of Cinnamon Is Best?
Although related, cinnamon and cassia are not obtained from the same plant. They should be treated as separate foods, both from a nutritional and a health standpoint.
Scientifically speaking, there is only one true cinnamon, which is most commonly called "Ceylon cinnamon," and comes from the plant Cinnamomum zeylanicum. An alternative scientific name for Ceylon cinnamon is Cinnamomum verum, which simply translates as "true cinnamon."
The term "cassia" never refers to Ceylon cinnamon but rather to other species of cinnamon, including Cinnamomum cassia (alternatively called Cinnamomum aromaticaum) and Cinnamomum burmannii. While most simply referred to as "cassia," you'll often find Cinnamomum aromaticaum being referred to as "Chinese cinnamon" or "Saigon cinnamon," and you'll find Cinnamomum burmannii being called "Java cinnamon" or "Padang cassia."
The study by neurological scientists at Rush University Medical Center found that feeding cinnamon to laboratory mice determined to have poor learning ability made the mice better learners.
This would be one of the safest and the easiest approaches to convert poor learners to good learners," said Kalipada Pahan, PhD, the lead researcher of the study and the Floyd A. Davis Professor of Neurology at Rush.
Some people are born naturally good learners, some become good learners by effort, and some find it hard to learn new tasks even with effort. Little is known about the neurological processes that cause someone to be a poor learner and how to improve performance in poor learners.
"Understanding brain mechanisms that lead to poor learning is important to developing effective strategies to improve memory and learning ability," Pahan said.
Cinnamon Role Reversal
The key to gaining that understanding lies in the hippocampus, a small part in the brain that generates, organizes and stores memory. Researchers have found that the hippocampus of poor learners has less CREB (a protein involved in memory and learning) and more alpha5 subunit of GABAA receptor or GABRA5 (a protein that generates tonic inhibitory conductance in the brain) than good learners.
The mice in the study received oral feedings of ground cinnamon, which their bodies metabolized into sodium benzoate, a chemical used as a drug treatment for brain damage. When the sodium benzoate entered the mice’s brains, it increased CREB, decreased GABRA5, and stimulated the plasticity (ability to change) of hippocampal neurons.
These changes in turn led to improved memory and learning among the mice.
"We have successfully used cinnamon to reverse biochemical, cellular and anatomical changes that occur in the brains of mice with poor learning," Pahan said.
The researchers used a Barnes maze, a standard elevated circular maze consisting of 20 holes, to identify mice with good and bad learning abilities. After two days of training, the mice were examined for their ability to find the target hole. They tested the mice again after one month of cinnamon feeding.
The researchers found that after eating their cinnamon, the poor learning mice had improved memory and learning at a level found in good learning mice. However, they did not find any significant improvement among good learners by cinnamon.
"Individual difference in learning and educational performance is a global issue," Pahan said. "We need to further test this approach in poor learners. If these results are replicated in poor learning students, it would be a remarkable advance."
Cinnamon Aids Against Parkinson’s Disease
Cinnamon has been a sweet spot for Pahan’s research. He and his colleagues previously that cinnamon can reverse changes in the brains of mice with Parkinson’s disease.
These studies have made the researchers spice connoisseurs: They used mass spectrometric analysis to identify the purer of the two major types of cinnamon.
"Although both types of cinnamon are metabolized into sodium benzoate, we have seen that Ceylon cinnamon is much more pure than Chinese cinnamon, as the latter contains coumarin, a hepatotoxic (liver damaging) molecule," Pahan said.
