New research shows that people who drink coffee have higher cholesterol levels, especially if they drink unfiltered varieties.
Researchers found that among more than 21,000 Norwegian adults, those who drank a few cups of coffee a day had slightly higher cholesterol levels than those who did not. However, the size of the difference depends on the method of brewing.
For example, people who drank “least-filtered” coffee pressed with French press had the greatest effect on cholesterol: On average, those who drank six or more cups a day had a total cholesterol level of eight to 12. , against non-drinkers.
The next is espresso lovers, followed by women who drank filtered drip coffee (no effect of cholesterol on male colleagues).

Unfiltered brewing includes brewed coffee made with a French press or “piston”. Espresso also falls into this category, but it is relatively more filtered than other varieties, said Lohen, a UiT professor at the University of Arctic in Norway.
The brewing method is important because coffee contains natural fats that can raise blood cholesterol. Researchers have found that unfiltered coffee can be high in hot water for a long time.
In fact, according to Lohen, a Tromso study from Norway for the first time in the 1980s showed that “everyone is making beer.”
He noted that in those days, brewed coffee was an unfiltered variety. But now espresso and plunger coffees have become popular, so Lohen and his colleagues used the latest data from the Tromso study to study the link between these stimulants and blood cholesterol.
“Norwegians love coffee, and Norway is the second largest consumer of coffee in the world,” Lohen said.
The findings, published in Open Heart magazine on May 10, are based on data on coffee drinking habits, exercise levels and alcohol consumption in more than 21,000 adults aged 40 and older.
On average, participants drank four to five cups of coffee per day. Studies have shown that those who do not drink brewed or French press coffee — six or more cups a day — have the highest cholesterol levels.
Then came people who said they drank three to five cups of espresso a day. Their total cholesterol was about 4-6 mg / dL higher than that of non-espresso drinkers. Finally, women who drank at least six cups of filtered coffee per day had an average of 4 mg / dL higher than women who did not drink filtered coffee.
However, there are some caveats from a registered nutritionist who did not participate in the study.
First, there is no information about the participants ’overall diet,” said Connie Diekman, a nutrition and nutrition consultant and former president of the Academy of Nutrition and Nutrition.
Dickman noted that it is unknown whether people regularly wash the coffee they want with sugar and cream.
So, he says, the question remains, is it coffee, cream, or the food that people eat from those cups of coffee?
“Coffee, in itself, is probably a very small player in raising cholesterol,” Dickman said. “So instead of worrying about how coffee can affect cholesterol, review your diet and create a healthier lifestyle.”
Lohen also drew attention to the larger picture, noting that normal coffee consumption (up to five cups a day) is associated with a reduced risk of heart disease and longer life expectancy.
Angel Planells is a Seattle-registered nutritionist and representative of the Academy of Nutrition and Dietetics. According to him, filtered or instant coffee may be the best choice for people who notice cholesterol. But once again, overall nutrition and lifestyle are key.
If you really like this latte or mocha, Planells says, there may be other ways to eliminate some “bad” fat from your diet – like cutting out processed meats or fried foods.
According to Planells, some people need to pay special attention to the caffeine content of coffee, including pregnant women and people with caffeine side effects, such as difficulty sleeping or “shaking.”
