You may have heard that drinking coffee can help you reduce your risk of blood sugar problems.
In fact, numerous scientific studies have linked higher coffee intake to a reduced risk of developing type 2 diabetes.
However, according to brand new research using a cutting-edge technique, only one type of coffee can truly give you that diabetes protection…
Filtered, boiled, espresso, or French press?
Research conducted by scientists from two separate Swedish Universities — Chalmers University of Technology and Umeå University — got deep into the specifics of coffee benefits.
How? They used a technique known as metabolomics.
Metabolomics makes it possible to identify the blood concentration of specific molecules from a given food or drink. That way, researchers are able to get an objective measurement of intake instead of simply relying on self-reported intakes from questionnaires that are prone to error. Previous studies on coffee have relied heavily on self-reporting.
The teams were specifically looking at the connection between filtered coffee (the type where you add the coffee to a machine that uses a filter and lets the hot water drip through) vs. boiled coffee (where grounds are added directly to boiling water) — and the effects of either on blood sugar.
And, here’s what the research all came down to…
Coffee can help reduce the risk of developing type 2 diabetes — but only filtered coffee (like you might prepare in a Mr. Coffee “drip” style coffee maker).
In fact, the researchers discovered that people who drank two to three cups of filtered coffee a day had a whopping 60 percent lower risk of developing type 2 diabetes than people who drank less than one cup of filtered coffee a day.
On the other hand, drinking boiled coffee had absolutely zero effect on diabetes risk.
It’s important to note that while boiled coffee isn’t common in the U.S. — that’s more of a European thing — there’s growing popularity in using a French press, Moka pot, perculator and filterless coffee makers.
I imagine by now, you’re wondering why the coffee filters matter so much…
The not-so-healthy component of coffee that gets caught in filters
You see, it all comes down to the diterpenes — compounds in coffee that actually increase your risk of heart and blood vessel disease.
“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,” says Rikard Landberg, Professor in Food Science at Chalmers, and Affiliated Professor at the Department of Public Health and Clinical Medicine at Umeå University.
So, if you’re a coffee-lover, drink up — but only if it’s filtered. At least two cups a day could lower your risk of type 2 diabetes by as much as 60 percent.
