Cherries may help lower blood sugar

Article Date: 21 Nov 2005
Researchers have identified a group of naturally occurring chemicals
abundant in cherries that could help lower blood sugar levels in people
with diabetes.
In early laboratory studies using animal pancreatic cells, the
chemicals, called anthocyanins, increased insulin production by 50
percent, according to study leader Muralee Nair, Ph.D., a natural
products chemist at Michigan State University in East Lansing.
But you might want to limit the candied maraschino cherries, as they
contain extra sugar and fewer beneficial cherry pigments, the
researcher says.

Buckwheat decreases blood glucose

Researchers in Canada have found new evidence that buckwheat, a grain
used in making pancakes and soba noodles, may be beneficial in the
management of diabetes.
In a controlled study, extracts of the seed lowered blood glucose
levels by 12 percent to 19 percent when fed to diabetic rats, according
to study leader Carla G. Taylor, Ph.D., an associate professor in the
Department of Human Nutritional Sciences at the University of Manitoba
in Canada.

Cinnamon lowers blood sugar levels

Several compounds isolated from cinnamon may one day become the key
natural ingredients in a new generation of products aimed at lowering
blood sugar levels, according to USDA researchers.
In test tube studies, the compounds, called polyphenolic polymers,
increased sugar metabolism in rodent fat cells 20-fold. The study was
conducted by the USDA's Richard A. Anderson, Ph.D., and his colleagues
at the University of California in Santa Barbara.
In a related finding published in another journal (Diabetes Care),
members of Anderson's research team reported that less than a
half-teaspoon of cinnamon daily for 40 days significantly lowered blood
sugar levels among 60 volunteers with Type 2 diabetes.

Tea fights cataracts, boosts insulin activity
Category: Nutrition/Agriculture News
Article Date: 21 Nov 2005
New research in animals suggests that tea may be a simple, inexpensive
means of preventing diabetes and its ensuing complications, including
cataracts. Researchers fed green and black tea to diabetic rats for
three months and then monitored the chemical composition of the rats'
blood and eye lenses.
At levels that would be equivalent to less than five cups of tea per
day for a human, both teas significantly inhibited cataract formation
relative to a control group which did not get tea, according to Joe
Vinson, Ph.D., a chemist at the University of Scranton (Penn.) and lead
author of the paper.
Another study on tea, done by researchers from the U.S. Department of
Agriculture, found that the popular beverage may increase insulin
activity.
Using black, green and oolong teas, the scientists found that tea
increased insulin activity by about 15-fold in tests using fat cells
obtain from rats.
The effect was primarily due to epigallocatechin gallate, an active
compound found in tea, says study leader Richard A. Anderson, Ph.D., of
the USDA's Agricultural Research Service in Beltsville, Md.
