Coffee 'reduces risk of diabetes

Coffee 'reduces risk of diabetes London - Arabstoday Drinking coffee can help reduce the risk of diabetes, say scientists. A study found three compounds contained in the beverage can block the toxic build up of a protein, which is known to trigger the long-term condition. Type 2 diabetes occurs when the body doesn't prevent enough insulin for it to function properly but the coffee extracts were also shown to prevent insulin-producing cells from being destroyed. Researchers now believe the coffee extracts - caffeine, caffeic acid, and chlorogenic acid - could help develop more effective treatment. Lead researcher Kun Huang from Huazhong University of Science and Technology said: 'We found three major coffee compounds can reverse this toxic process and may explain why coffee drinking is associated with a lower risk of type 2 diabetes.' All of the compounds were shown to have a positive effect during laboratory tests, however caffeine was the least effective of the three. As a result Huang states that decaffeinated coffee could be more beneficial than regular options. Huang added: 'In decaffeinated coffee, the percentage contents of caffeic acid and chlorogenic acid are even higher [than in regular coffee], whereas the level of caffeine is greatly reduced. 'We expect that decaffeinated coffee has at least equal or even higher beneficial effect compared to the regular caffeinated types.' The new study, published in the Journal of Agricultural and Food Chemistry, supports previous studies which have found people who drink four or more cups of coffee a day have a 50 per cent lower risk of getting type 2 diabetes. Despite the findings Joe Vinson from the University of Scranton, highlights that the concentrations of coffee compounds used in the Chinese study are much higher than those found in a typical coffee consumption. Researchers now plan on carrying out further studies in animals and humans to better understand the link between coffee consumption and reduced risk of diabetes. Diabetes affects 2.8 million people in the UK and it is thought that a further one million people have the condition but are unaware of it. Type 2 diabetes is often associated with obesity and can often be controlled by following a healthy diet and monitoring blood glucose levels.
