Heavy coffee drinkers have a lower risk of developing Type 2 diabetes, and now scientists in China may have discovered why.
In 2009, a study published in the Archives of Internal Medicine reported that people who drank the most coffee seemed to have the lowest risk of developing type 2 diabetes. That study reported that with each cup of coffee consumed daily, the risk of type 2 diabetes dropped by 7 percent.
Chinese Researchers have cited the protective benefits of compounds in coffee that inhibit a substance called human islet amyloid polypeptide (hIAPP), which has been linked to diabetes, stated science and health news website Science Daily in a report on the new study.
A U.S. diabetes expert was guardedly optimistic about the study's conclusions.
"Scientifically, this is a very nice paper, but it has its limitations," Dr Vivian Fonseca, president of medicine and science at the American Diabetes Association, told Medical ID wearers.
"This was done in cells, not in animals or people. We also don't know if the [abnormal deposits arising from hIAPP] are the most important thing in the development of type 2 diabetes, or if it's something that develops later."
Fonseca advised that it's too soon to make any recommendations about drinking coffee to prevent diabetes, adding, "if you want to prevent diabetes, there are some very straightforward things to do. You can walk for 30 minutes most days of the week, and reduce calories a little bit and reduce your weight a little."
