14 November, 2013 – Regular, moderate coffee consumption may decrease an individual's risk of developing type 2 diabetes, according to research highlighted in a report published by the Institute for Scientific Information on Coffee (ISIC).
More than 370 million people worldwide have diabetes making it one of the most significant health problems(1). To mark World Diabetes Day, ISIC has published an updated report outlining the latest research on coffee and type 2 diabetes.
Key research findings include:
The report also puts forward some of the key mechanistic theories that underlie the possible relationship between coffee consumption and the reduced risk of diabetes. These includes the 'Energy Expenditure Hypothesis', which suggests that the caffeine in coffee stimulates metabolism and increases energy expenditure and the 'Carbohydrate Metabolic Hypothesis', whereby it is thought that coffee components play a key role by influencing the glucose balance within the body.
There is also a subset of theories that suggest coffee contains components that may improve insulin sensitivity though mechanisms such as modulating inflammatory pathways, mediating the oxidative stress of cells, hormonal effects or by reducing iron stores.
The updated report is based on a report from the World Congress on Prevention of Diabetes, held in 2012 and is updated with the latest research from this field published over the past year. Please contact us for the full summary.
