New evidence shows that drinking coffee may help prevent diabetes and lower blood sugar, according to a EurekAlert report. In a study, published in Journal of Agricultural and Food Chemistry, scientists fed either water or coffee to a group of laboratory mice commonly used to study diabetes. Coffee consumption prevented the development of high-blood sugar and also improved insulin sensitivity in the mice, thereby reducing the risk of diabetes. Coffee also caused a cascade of other beneficial changes in the fatty liver and inflammatory adipocytokines related to a reduced diabetes risk.
Past studies have suggested that regular coffee drinking may reduce the risk of type 2 diabetes but until now little of that evidence has come from studies on lab animals.
