Type 2 diabetes is the most common of the so-called lifestyle diseases that affect modern man. It is linked to obesity and is caused when the body does not produce enough insulin or when the cells are unable to utilize it.

It is estimated that 170 million people worldwide suffer from this disease. The disease is characterized by failure of the pancreatic beta cells to adequately respond to the increased demands for insulin that occur as a result of obesity-related insulin resistance. This raises the blood sugar levels beyond control.

Now Dr Graham Rena and his team at the Neurosciences Institute of the University of Dundee and colleagues have found that constituents of black team may help fulfil this demand for insulin.

"What we have found is that these constituents can mimic insulin action on proteins known as foxos," Dr Rena said, adding that it was too early for people to start drinking black tea.

“Foxos have previously been shown to underlie associations between diet and health in a wide variety of organisms including mice, worms and fruit flies,” Dr Rena continued. “The task now is to see whether we can translate these findings into something useful for human health."

Reporting in the journal Aging Cell, the authors stressed that further research was needed before anything conclusive could be revealed.

Bringing some changes into routine lifestyle practices is very helpful in managing type 2 diabetes. However failure to control blood sugar levels leads to many complications including heart disease, blindness, nerve damage and kidney damage.
