Type 2 diabetes affects insulin in the body. Everyone needs insulin to live and has an essential job to help keep the body healthy. Insulin allows blood glucose to enter cells and feed the body. When a person has type 2 diabetes, the body further breaks down the carbohydrates in food and drink and turns them into glucose. The pancreas responds to this by releasing insulin; however, that insulin does not work properly, and blood sugar levels continue to rise and more insulin is released. This wreaks havoc on the body, but there may be a drink that helps to decrease the risk of developing this condition.
The researchers focused on a four-year period and their findings were published in a 2014 study.
People who increased their coffee intake by more than a cup a day were found to have an 11% lower risk of developing type 2 diabetes.
The compounds found in coffee appear to block the toxic buildup of a protein linked to an increased risk of type 2 diabetes.
Professor Kun Huang, a professor of biological pharmacy at Huazhong University of Science and Technology, said: "We found that three major coffee compounds can reverse this toxic process and can explain why coffee consumption is associated with a lower risk of type 2 diabetes".
Previous studies have also found that people who drink four or more cups of coffee a day have a 50% lower risk of getting type 2 diabetes.
The study was published in the Journal of Agricultural and Food Chemistry.
Explaining the reduced risk of type 2 diabetes among coffee consumers is an ongoing effort, according to Dr. Vivian Fonseca, president of medicine and science at the American Diabetes Association.
"This study tested how oral caffeine affects carbohydrate metabolism in patients with type 2 diabetes, for whom decreased insulin sensitivity may result in exaggerated hyperglycemic responses to glucose and other carbohydrates, which would worsen the glycemic dysregulation found in the disease" .
The study concluded that acute caffeine administration impaired postprandial glucose metabolism in these diabetic patients.
However, there were also increases in some patients.
