Type 2 diabetes sufferers may be able to control their blood sugar levels by consuming moderate amounts of red wine and tea, a new study has indicated.
Red wine has been shown to protect people from heart disease, even when they follow a diet high in saturated fat, and the healing powers of tea are becoming the stuff of legend.
Now, researchers at the University of Massachusetts Amherst have shown that certain antioxidants found in red wine and tea may help regulate the blood sugar of people with type 2 diabetes by inhibiting the action of alpha-glucosidase that controls the absorption of glucose from the small intestine, and protect the body from complications such as high blood pressure and heart disease.
"Levels of blood sugar, or blood glucose, rise sharply in patients with type 2 diabetes immediately following a meal. Red wine and tea contain natural antioxidants that may slow the passage of glucose through the small intestine and eventually into the bloodstream and prevent this spike, which is an important step in managing this disease," said Kalidas Shetty, a food scientist at the University of Massachusetts.
For the study, both red and white wines were tested in the laboratory using in vitro enzyme studies to determine how well they could stall the activity of a target enzyme called alpha-glucosidase, responsible for triggering the absorption of glucose by the small intestine.
