You Should Go For Filtered Coffee To Avoid Diabetes, Study Says

The way you prepare your coffee may have an effect on its health benefits. A new study shows that drinking filtered coffee could help reduce the risk of developing diabetes. 

Researchers said people who drink two to three cups of filtered coffee everyday may be 60 percent less likely to have type 2 diabetes. The team analyzed data collected since the early 1990s from residents in Sweden. 

However, those who consumed boiled coffee did not experience any changes in their risk of having diabetes. Boiled coffee is a common preparation method that simply puts ground coffee into boiling water and left to brew for a few minutes.

“Our results now clearly show that filtered coffee has a positive effect in terms of reducing the risk of developing type 2 diabetes,” Rikard Landberg, a professor at Chalmers University of Technology and Umeå University in Sweden, said in a statement. “But boiled coffee does not have this effect.”

Previous studies linked boiled coffee to higher risk of heart and vascular diseases. That is because of the molecule called diterpenes that remains after the boiling process.

Researchers of the latest study, published in Journal of Internal Medicine, explained that when people filter coffee, diterpenes gets captured in the filter while healthy molecules stay in the drink. This helps boost the health benefits of the hot beverage.

Researchers used a technique called metabolomics to see the effects of filtered and boiled coffee on diabetes. It enabled the team to identify blood concentration of specific molecules in product samples. 

"Metabolomics is a fantastic tool, not just for capturing the intake of specific foods and drinks, but also for studying the effects that that intake has on people's metabolism,” Lin Shi, lead study author, said. “We can derive important information on the mechanisms behind how certain foods influence disease risk.” 

Coffee Preparation Methods and Their Effects

Researchers cited that there are other ways of making coffee that may not help reduce the risk of having type 2 diabetes. Landberg said classic espresso machines, a French press and coffee-pods do not use filters and the process appear similar to traditional boiling methods, which means they may have no effects on diabetes.

Researchers noted they have to identify how instant coffee causes changes in the body that may help avoid problems with blood sugar or contribute to the disease.
