Sunday 01 Mar 2015 - 16:05 Makkah mean time-10-5-1436  Three cups of tea a day can cut your risk of diabetes (Google image) London, (IINA) - Drinking three cups of tea a day can cut the risk of diabetes, says new research, Daily Mail reported.
The new agency noted that two studies one American and another Japanese shows that black tea has a glucose-lowering effect that could help prevent and manage type 2 diabetes.
Experts say the findings suggest around three cups a day might help the body control blood sugar levels more effectively.
In the studies, the scientists investigated extracts from black tea in the laboratory and they discovered the action of natural ingredients in black tea could lead to reductions in blood sugar.
The US research led by Lisa Striegel from Framingham State University analyzed black tea leaves after being immersed in hot water. They extracted a number of polyphenols – antioxidants – all of which were shown to block enzymes that push up blood sugar from the digestion of carbohydrates.
They had significant activity against the enzymes, alpha amylase and alpha-glucosidase.
This suggests that black tea extract may reduce levels of glucose normally associated with these digestive enzymes, says a report in Frontiers of Nutrition.
In a second study from Japan, a freeze-dried powder extract of black tea leaves was found to have a similar effect on the two enzymes.
The study from the Hokkaido Pharmaceutical University School of Pharmacy was published in the Journal of Ethno pharmacology.
From her side Dr Catherine Hood from the industry backed Tea Advisory Panel (TAP) said Diabetes is a condition of disordered glucose metabolism.
Dr Tim Bond also from TAP said the studies provided additional evidence that around three cups of tea a day might produce anti-diabetic benefits.
