Are you the kind who finds coffee to the most important drink of the day? If so, drink filtered coffee instead of boiled coffee, and you would help prevent type 2 diabetes.
“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,” said Rikard Landberg, Professor at Umea University. “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,” Landberg said.
According to the research, people who drink over two or three cups of filtered coffee a day had a 60% lower chance of developing type 2 diabetes. Boiled coffee showed no such health effect.
The research used a new technique called Metabolomics. “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. We can derive important information on the mechanisms behind how certain foods influence disease risk,” said lead author of the study, Lin Shi.
Many people wrongly believe that coffee has only negative effects on health, according to the researchers. They believe that previous studies have shown that boiled coffee increases the risk of heart and vascular diseases, due to the presence of diterpenes, a type of molecule found specifically in boiled coffee and not in filtered coffee.
The study also says that its not just the filtration process, but the quality of the beans and how the drink is prepared that might add to the impact on health.
