Also Helps Cholesterol -- But More Than A Sprinkle Required

Dec. 5, 2003 -- A spicy tip: Cinnamon can improve glucose and cholesterol

levels in the blood. For people with type 2 diabetes, and those fighting

high cholesterol, it's important information.

Researchers have long speculated that foods, especially spices, could help

treat diabetes. In lab studies, cinnamon, cloves, bay leaves, and turmeric

have all shown promise in enhancing insulin's action, writes researcher Alam

Khan, PhD, with the NWFP Agricultural University in Peshawar, Pakistan. His

study appears in the December issue of Diabetes Care.

Botanicals such as cinnamon can improve glucose metabolism and the overall

condition of individuals with diabetes -- improving cholesterol metabolism,

removing artery-damaging free radicals from the blood, and improving

function of small blood vessels, he explains. Onions, garlic, Korean

ginseng, and flaxseed have the same effect.

In fact, studies with rabbits and rats show that fenugreek, curry, mustard

seeds, and coriander have cholesterol-improving effects.

But this is the first study to actually pin down the effects of cinnamon,

writes Kahn. Studies have shown that cinnamon extracts can increase glucose

metabolism, triggering insulin release -- which also affects cholesterol

metabolism. Researchers speculated that cinnamon might improve both

cholesterol and glucose. And it did!

The 60 men and women in Khan's study had a diagnosis of type 2 diabetes for

an average of 6 1-2 years but were not yet taking insulin. The participants

in his study had been on antidiabetic drugs that cause an increase in the

release of insulin. Each took either wheat-flour placebo capsules or 500

milligram cinnamon capsules.

* Group 1 took 1 gram (two capsules equaling about one-quarter of a

teaspoon) for 20 days.

* Group 2 took 3 grams (six capsules, equaling a little less than one

teaspoon) for 20 days.

* Group 3 took 6 grams (12 capsules, equaling about one and

three-quarters teaspoons) for 20 days.

Blood samples were taken at each level of the study.

Cinnamon made a difference! Twenty days after the cinnamon was stopped,

there were significant reductions in blood glucose levels in all three

groups that took cinnamon, ranging from 18 to 29%. But these was one

peculiar finding that researchers don't understand at this point. Only the

group that consumed the lowest level of cinnamon continued with

significantly improved glucose levels -- group 1. The placebo groups didn't

get any significant differences.

Taking more cinnamon seems to improve the blood levels of fats called

triglycerides. All the patients had better triglyceride levels in their

40-day tests -- between 23% to 30% reductions. Those taking the most

cinnamon had the best levels.

In groups taking cinnamon pills, blood cholesterol levels also went down,

ranging from 13% to 26%; LDL cholesterol also known as " bad " cholesterol

went down by 10% to 24% in only the 3- and 6-gram groups after 40 days.

Effects on HDL ( " good cholesterol " ) were minor.

Cinnamon should be part of our daily diet -- whether we have type 2 diabetes

or not, writes Kahn. However, for the best effects, just a sprinkle isn't

enough.
