Filtered Coffee Helps Prevent Type 2 Diabetes

JAKARTA – Coffee can help reduce the risk of developing type 2 diabetes. But this benefit can be obtained only from filtered coffee, not boiled coffee.

New research from Chalmers University of Technology and Umeå University in Sweden, shows that the choice of coffee processing method affects the health effects of coffee. Many previous studies have shown a link between high coffee intake and a reduced risk of type 2 diabetes. (Also read: Brewed with mineral water, the taste of coffee becomes richer )

“We have identified specific molecules – biomarkers – in the blood of those who take part in the study, which indicate the intake of different types of coffee. These biomarkers are then used for analysis when calculating risk of type 2 diabetes. Our results now clearly show that filtered coffee has an effect. positive in terms of reducing the risk of developing type 2 diabetes. But boiled coffee does not have this effect, “said Rikard Landberg, Professor of Food Science at Chalmers, and Associate Professor in the Department of Public Health and Clinical Medicine at Umeå University.

Using these biomarkers, the researchers were able to show that people who drank two to three cups of filtered coffee a day had a 60% lower risk of developing type 2 diabetes than people who drank less than one cup of filtered coffee a day. Consumption of boiled coffee had no effect on diabetes risk in the study.

Filtered coffee is the most common method of preparation in many places. Boiled coffee in this case refers to an alternative method of making coffee used in some other countries, where coarse ground coffee is added directly to boiling water and allowed to brew for a few minutes. All data used in this study came from a group of Swedish subjects and were collected in the early 1990s.

According to Rikard Landberg, many people mistakenly believe that coffee only has a negative impact on health. This could be because previous research has shown that boiled coffee increases the risk of heart and blood vessel disease, due to the presence of diterpenes, a type of molecule found in boiled coffee.

“But it has been proven that when you filter coffee, the diterpenes are captured in the filter. As a result, you get the health benefits of many other molecules that are present, such as different phenolic substances. In moderate amounts, caffeine is also positive for health,” he said.

The question is whether Ditpenes also have a negative impact on sugar metabolism and is therefore why boiled coffee does not help lower diabetes risk, as filtered coffee does. Researchers still can’t say exactly the nature of the link.

There are many other types of coffee preparation that were not specifically studied in this study, such as instant coffee, espresso, cafetière, and percolator coffee. This type of coffee was not common among the Swedish study population when the data were collected. (Also read: Be alert, the serious impact of diabetes mellitus results in blindness )

But given that espresso coffee, from the classic espresso machine or now popular coffee beans, is also brewed unfiltered, Rikard Landberg believes that the health effects could be similar to that of boiled coffee, in terms of the risk of type 2 diabetes. which is similar to boiled coffee, so it may also not have a positive effect on reducing the risk of type 2 diabetes.

It’s unclear whether instant coffee, the UK’s most popular type, would resemble filtered or boiled coffee in this respect. Reporting from Science Daily, Tuesday (15/12) Rickard Landberg emphasizes that the health effects of coffee do not depend only on being filtered or not. They also differ from how coffee beans, and beverages in general, are managed.
