Three cups of filtered coffee may protect you from diabetes

London: In a good news for coffee lovers, researchers have found that coffee can help reduce the risk of developing type 2 diabetes – but only filtered coffee, rather than boiled coffee.

The study, published in the Journal of Internal Medicine, shows that the choice of preparation method influences the health effects of coffee.

The findings from Chalmers University of Technology and Umea University in Sweden, offer new insight into this connection, using a novel method to help differentiate 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,” said study researcher 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 added.

With the use of these biomarkers, the researchers were able to show that people who drank two to three cups of filtered coffee a day had a 60 per cent 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 the diabetes risk in the study.

To differentiate the diabetes risk for boiled and filtered coffee, a new technique called metabolomics was used, in combination with classic dietary questionnaires.

Metabolomics makes it possible to identify the blood concentration of specific molecules from a given food or drink and use that as an objective measurement of intake – instead of simply relying on self-reported intakes from the questionnaires, which are prone to large errors.

“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 study lead author Lin Shi.

According to the researchers, many people wrongly believe that coffee has only negative effects on health.

This could be because 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 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,” Landber said.

Many other types of coffee preparation were not specifically investigated in the study, such as instant, espresso, cafetiere, and percolator coffee.

The study stresses that the health impacts of coffee do not depend solely on if it is filtered or not. They also vary with how the coffee beans, and the drink in general, are managed.

Coronavirus

Mumbai, Jan 24: Two persons, who arrived here from China, were placed under isolation for medical observations for suspected exposure to Coronavirus, BrihanMumbai Municipal Corporation officials said on Friday. However, later, the Union Health Ministry announced that both have tested negative.

Besides, two other suspected cases — one each from Bengaluru and Hyderabad — also proved to be negative, as per the reports of the ICMR-NIV, Pune.

One of Mumbai patients has tested positive for Rhinovirus, one of the routine common cold virus.

Earlier, the two Mumbai cases were secluded in the BMC’s Kasturba Hospital – which specialises in such diseases – after they were detected with possible symptoms following thermal screening of nearly 1,800 passengers coming from Chinese airports to the Chhatrapati Shivaji Maharaj International Airport since the past five days.

The duo had complained of cold-related symbols and mild cough and further medical tests were conducted on them, said an official.

The CSMIA medical teams have been advised to send travellers from China exhibiting any similar symptoms to the Kasturba Hospital for further medical protocols.

However, no passenger with a history of visiting China’s Wuhan city in the past fortnight has been found positive during thermal screening for Coronavirus.

Besides setting up the seclusion ward in the hospital, the civic health authorities have also issued instructions to all private medicos in the city to inform the BMC in case they detect any signs of Coronavirus from their patients who have recently returned from a China trip.

As a precautionary measure, the CSMIA started thermal screenings of all inbound passengers in the pre-immigration area, arriving by Air China and RwandAir which operate flights between Mumbai and China, since January 19.

The city Health Department and state Health Ministry are closely monitoring the situation on a regular basis amid global reports of over two dozen deaths due to Coronavirus and more than 850 under treatment for the disease.

Stock Market Down

Mumbai, Jan 24 : Fears that the outbreak of coronavirus in China may disrupt economic activity and global growth has sent the stock markets tumbling.

Chinese health authorities on Friday said that 830 cases of pneumonia caused by coronavirus were confirmed in 29 provincial-level regions in the country. The pneumonia has so far claimed 25 lives.

A sharp adverse reaction from Asian, US and European markets was witnessed because China is entering one of its busiest travel periods on account of its Lunar New Year holiday. The virus outbreak could hurt demand.

On Thursday, Chinese stock markets logged its biggest slide in eight months. However, Indian markets closed higher as the oil prices plunged significantly. The global oil benchmark, Brent slipped to $62 a barrel as the virus outbreak in China may dent fuel demand.

Meanwhile official sources told IANS that though over 500 Indian students study in Wuhan city’s medical colleges and universities, most of them had left for home for the Chinese New Year holidays.

Deaths due to the virus have revived memories of the SARS epidemic, caused by a coronavirus, which killed nearly 800 people and infected more than 8,000 others across the world in 2002-2003.
