Drinking coffee 'may reduce risk of diabetes'Caffeine is the key ingredient
The stimulating effect of a cup of coffee was recently called into question - but a new study suggests that it may help reduce the risk of diabetes.
Diabetes is a growing medical problem linked to the obesity epidemic. In the UK alone around half a million million people are estimated to have the serious health condition, but don't know it.
In this new study, scientists fed either water of coffee to a group of laboratory mice of a type that are commonly used to study diabetes.
Coffee consumption prevented the development of high-blood sugar levels and also improved insulin sensitivity in the mice, thereby reducing the risk of diabetes.
But there were other benefits linked to the coffee also - including in the fatty liver and inflammatory adipocytokines related to a reduced diabetes risk.
The scientists, from Nagoya University in Japan, noted that previous studies had suggested the link between coffee drinking and reduced levels of diabetes 2.
This new research is one of the first to demonstrate the effect directly in laboratory animals. Study leader Fumihiko Horio noted that the study shows that caffeine "may be one of the most effective anti-diabetic compounds in coffee".
The research is published in the Journal of Agricultural and Food Chemistry.
