Drinking coffee has a preventive effect when it comes to protecting against the development of type 2 diabetes, according to Danish scientist Prof. Kjeld Hermansen.
Professor Hermansen represents the Department of Clinical Medicine at Aarhus University in Denmark. Speaking about how coffee can affect diabetes, the scientist noted in an interview with Express:
“Although epidemiological studies cannot prove a causal relationship, all recent meta-analyses have found a clear association between coffee consumption and a reduced risk of developing type 2 diabetes.”
According to Hermansen, scientists have analyzed data from over a million people and collected for 24 years. As a result, they concluded that people with a high level of coffee consumption had a 29 percent lower risk of developing type 2 diabetes compared to those who consumed minimal coffee.
The risk of type 2 diabetes can be reduced by 6 percent with each additional cup of coffee per day, the professor states. Coffee's antidiabetic effects, he says, are very similar across regions; observed in men and women, in thin and obese people, as well as in people who consume both unfiltered brewed coffee and filtered coffee Kjeld Hermansen recalled that coffee contains hundreds of biologically active substances, so it is difficult to elucidate in detail the mechanism of action underlying its antidiabetic effect. Possible mechanisms for this effect of coffee may include thermogenic, antioxidant, anti-inflammatory actions.

For example, the biologically active cafestol in coffee has been shown to increase glucose uptake by muscle cells and improves beta cell function.”
Professor Hermansen recommended drinking up to three to five cups of coffee daily “to experience the greatest anti-diabetic effect.” He added that another important property of coffee is to reduce the risk of fatty liver.
Proven: coffee protects against diabetes
