Coffee can help reduce the risk of developing type 2 diabetes but just filtered coffee, rather than boiled coffee. New research study from Chalmers University of Innovation and Ume University, both in Sweden, show that the option of preparation method influences the health effects of coffee.

Numerous previous studies have actually shown a connection between high coffee intake and a minimized risk of establishing type 2 diabetes. Now, a research study from Chalmers University of Innovation and Ume University, offers new insight into this connection, using an unique approach to help distinguish between the effects of filtered coffee and boiled coffee.

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

With making use of these biomarkers, the researchers had the ability to show that people who drank 2 to 3 cups of filtered coffee a day had a 60% lower threat of establishing type 2 diabetes than people who drank less than one cup of filtered coffee a day. Consumption of boiled coffee had no effect on the diabetes risk in the research study.

Filtered coffee is the most common approach of preparation in many places, including the US and Scandinavia. Boiled coffee in this case refers to an alternative method of coffee preparation often used in Sweden and some other nations, in which coarse ground coffee is simply added straight to boiling water and left to brew for a couple of minutes. All the information used in the research originated from a group of Swedish subjects and was gathered in the early 1990s.

According to Rikard Landberg, many individuals incorrectly think that coffee has only unfavorable impacts on health. This could be since previous research studies have shown that boiled coffee increases the threat of heart and vascular diseases, due to the existence of diterpenes, a type of particle found in boiled coffee.

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

The question is whether diterpenes likewise negatively affect sugar metabolic process and are therefore the cause of why boiled coffee does not help decrease the threat of diabetes, in the way that filter coffee does. The scientists still can not say the specific nature of the link.

Numerous other types of coffee preparation were not specifically examined in the research study, such as instant, espresso, cafetire, and percolator coffee. These kinds of coffee were not typical amongst the Swedish research study population when the data was collected.

However considered that espresso coffee, from traditional espresso machines or the now popular coffee-pods, is also brewed without filters, Rikard Landberg believes the health effects could therefore resemble boiled coffee, in regards to the threat of type 2 diabetes. Coffee made in a cafetire, or French press, is prepared in a comparable method to boiled coffee, so it may also not have the positive impact of reducing type 2 diabetes danger. It is uncertain whether instantaneous coffee, the most popular enter the UK, would be more similar to filtered or boiled coffee in this regard.

However the researchers are careful to note that no conclusions can be drawn yet regarding these other preparation techniques. Rickard Landberg likewise stresses that the health effects of coffee do not depend exclusively on if it is filtered or not. They likewise differ with how the coffee beans, and the drink in general, are handled.

To differentiate the diabetes risk for boiled and filtered coffee, a new strategy called metabolomics was used, in combination with timeless dietary surveys. Metabolomics makes it possible to identify the blood concentration of specific particles from a given food or drink and utilize that as an unbiased measurement of consumption instead of simply depending on self-reported consumptions from the questionnaires, which are prone to big mistakes.

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 peoples metabolism. We can derive important information on the mechanisms behind how certain foods influence disease risk, says Lin Shi, Postdoctoral researcher and the lead author of the study.
