Effects on blood sugar control
Evidence has been mounting in recent years
concerning cinnamon's effects on maintaining a healthy blood sugar balance.
In one study cinnamon was noted to reduce fasting blood sugar levels as well
as triglycerides and LDL cholesterol in individuals with compromised blood
sugar control. Another study confirmed that cinnamon had moderate effects in
reducing fasting blood sugar levels in patients with poor glycaemic control.
Some researchers believe that these effects may stem from cinnamon's ability
to enhance insulin sensitivity which in turn may improve glucose tolerance.
This theory is based on the observation that cinnamon extract increases
phosphatidylinositol 3-kinase activity in the insulin signalling pathway,
thus potentiating insulin action.
Moreover, cinnamon's effects may not only be
confined to people with existing blood sugar problems. In a recent trial the
effects of cinnamon were assessed on the postprandial glucose response and
rate of gastric emptying in healthy subjects. The results showed that
cinnamon significantly delayed gastric emptying and lowered postprandial
glucose response, compared to placebo. That is, it would seem that cinnamon
may be of value for supporting glucose metabolism in healthy individuals as
well.
Antimicrobial effects
Traditionally cinnamon has been used for
tackling symptoms of gut infections owing to the belief that cinnamon has
antimicrobial effects and indeed recent studies support this. Researchers in
Korea have demonstrated that the growth of E.coli cells treated with
cinnamaldehyde was dramatically decreased after twelve hours of incubation.
Cinnaldehyde has also been shown to inhibit the growth of other pathogenic
organisms such as Vibrio cholerae, Salmonella typhymurium and yeasts
including Candida albicans.
Other effects
A pilot study on 15 women with polycystic
ovarian syndrome (PCOS) showed that treatment with cinnamon for eight weeks
significantly reduced insulin resistance. Further studies are warranted to
determine whether these results can be replicated in larger groups of
individuals.
Species of cinnamon
There are different species of the spice
cinnamon, two of the most renowned being Cinnamomum cassia and Cinnamomum
zeylanicum, both of which are commonly used as culinary ingredients.
Cinnamomum cassia originates from the bark of a small evergreen tree that is
indigenous to China and surrounding areas; it is the form of cinnamon that
has been investigated extensively in recent times and is the species under
review here.
