The American Chemical Society ( ACS) presented new findings on Wednesday to prove that drinking coffee may reduce the risk of type 2 diabetes.
The ACS said the study, conducted by researchers at Nagoya University in Japan, was based on animal tests.
The 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.
Additional lab studies showed that caffeine may be "one of the most effective anti-diabetic compounds in coffee," according to the ACS.
Past studies have suggested that regular coffee drinking may reduce the risk of type 2 diabetes. However, little of that evidence comes from studies on lab animals used to do research that cannot be done in humans.
Type 2 diabetes affects millions in the United States and is on the rise worldwide.
