Substances found in the popular drink have been linked to delaying the onset of type 2 diabetes – but few studies have tested the hypothesis.
Now, scientists from Denmark have found one of the previously untested substances could improve the function of cells and importantly – improve insulin sensitivity in laboratory mice.
Experts believe the finding could help to treat or even prevent the disease.
Pervious studies have considered drinking coffee could reduce the risk of developing diabetes.
After discounting caffeine as the reason for this – experts found a substance in coffee called cafestol could boost insulin secretion in pancreatic cells when they were exposed to glucose.
Type 2 diabetes occurs when the body does not produce enough insulin or the insulin produced does not work properly and can be linked to lifestyle factors such as being overweight.
Experts found the substance Cafestol also increased the uptake of sugar in the blood – glucose in muscle cells.
They found this was as effective as an anti diabetic drug.
Scientists have conducted a new study which has investigated how cafestol would help delay the onset of type 2 diabetes.
They tested the substance on mice.
Researchers found one group of mice – prone to type 2 diabetes – and fed cafestol had lower blood glucose levels.
They also found they had improved ability to produce insulin, compared to groups of mice which were not fed cafestol.
The study concluded: “Our results show that cafestol possesses antidiabetic properties in KKAy [diabetic] mice.
“Consequently, cafestol may contribute to the reduced risk of developing T2D [type 2 diabetes] in coffee consumers and has a potential role as an antidiabetic drug.”
The symptoms of type 2 diabetes are not always obvious, and many people could be suffering with the condition for years before they learn they have it.
Every week 4,500 people are diagnosed with type 2 diabetes across the UK.
However, experts warn thousands could be living with undiagnosed type 2 diabetes.
The research was published in the Journal of Natural Products.
