Why most Indian-Americans develop type 2 diabetes? Blame it on genetical reasons, say researchers in the United States.

A team at the Mayo Clinic in Minnesota says the 'type 2 diabetes' develops typically in adults when their bodies don't produce enough insulin to regulate sugar absorption.

Dr Sree Nair, according to reports said, said Indian-Americans had a much stronger tendency to develop the disease than Northern Europeans after comparing the absorption rate of insulin and glucose of the groups.

"Indian-Americans are less sensitive to insulin action, which means the same amount of insulin disposed of much less glucose in Asian Indians than Northern European Americans," said Nair.

Nair said he also found that Asian Indians produced more energy from the same amount of food as European Americans.

He said the findings may indicate that Indian-Americans are getting diabetes as their bodies have evolved to be insulin-resistant to store energy.

According to the World Health Organisation, India will be the diabetes capital of the world.
