Diabetes and obesity could be prevented by 'drinking three cups of coffee a day'

Many people probably start their day off with a coffee or two to help them wake up - but it turns out your morning cuppa may also be protecting you from certain health conditions.Researchers at the Karolinska Institut in Sweden recently found that drinking three cups of coffee every day could help to curb obesity and prevent diabetes.

Scientists believe calorie-free caffeinated drinks should be properly looked into as a new tool to tackle obesity and type 2 diabetes.

And the biggest benefit was in those who are genetically able to process caffeine more slowly, leaving more of it in their blood.Previous research has shown that there's a link between drinking 3-5 cups of coffee a day, and having a lower risk of type 2 diabetes and cardiovascular disease.Coffee is widely known to boost your metabolism, increase the amount of fat you burn and suppress your appetite.

Consuming 100mg a day, which is around one cup of coffee, increases energy expenditure by an estimated 100 calories daily.The new development in this research found being genetically able to metabolise caffeine slowly increased the amount of caffeine in the blood.This increased the fat-burning impact of the stimulant, and reduced type 2 diabetes.To reach their conclusions, the team had a look back over their earlier studies to reveal caffeine's effect on body fat and type 2 diabetes.They investigated how the link between caffeine and the body changes with people's genetic make-up.Scientists focussed on two common genetic variants that determine how fast caffeine is metabolised in the body: CYP1A2 and AHR genes.Participants were found to consume less caffeine when genetically predisposed to metabolise the stimulant slowly.But despite that, the same people have
