Coffee strained through a paper filter is associated with a lower risk of death – News

Drink the good old coffee brewed in a paper filter may contribute to the reduction of risk factors for cardiovascular disease and death.

A study carried out in Norway and published in the European Journal of Preventive Cardiology showed positive effects for those who drank the drink strained through a paper filter in relation to individuals who did not consume coffee.

They also compared it with the consumption of unfiltered coffee, in which the beans come into direct contact with hot water or in which there is a metallic filter, which does not remove the oils in the same way that paper does.

The unfiltered category includes, for example, espresso, instant coffee, those made in a French press, as well as capsules, which have become very popular in recent years.

According to the study authors, the lowest mortality of participants was observed among those who drank one to four cups of brewed coffee a day, while the highest death rate occurred in the group that drank more than nine cups of unfiltered coffee daily.

They make a reservation for variables that may have had an impact on the final results, such as the age of the participants, smoking, cholesterol and triglyceride levels, high blood pressure, body mass index and education.

Even so, the result of the research has a basis that goes back to 1983, when the first studies already related coffee to cholesterol, a risk factor for cardiovascular problems and, mainly, heart attack and stroke.

Later, new research showed that coffee has compounds called diterpenes, which increase blood fat.

“The concentration of these diterpenes in the final infusion strongly depends on the infusion method, a finding that explains most of the heterogeneous results published regarding the intake of coffee and blood lipids. A serving of unfiltered coffee contains about 30 times the concentration of kahweol and cafestol diterpenes, which increase lipids, compared to filtered coffee”, they say.

The authors of the work also point out that “the lower mortality associated with filtered coffee compared to no coffee may be due to the fact that coffee is rich in antioxidants, including polyphenols”.

These compounds are known for their antioxidant power, as well as exerting antithrombotic effects and improving endothelial (blood vessel) dysfunction.

“Coffee consumption is also associated with a lower risk of diabetes, which is a risk factor for CVD. [doença cardiovascular]”, they observe.

Regardless of how coffee is made, moderate consumption (up to three cups a day) has been pointed out in a large number of ways. study conducted in the UK beneficial in reducing mortality.

The survey analyzed data from nearly 470,000 individuals, with 58.4% consuming 0.5 to 3 cups of coffee a day and another 22.1% not drinking.

“Our results suggest that regular coffee consumption is safe, as even high daily coffee intake was not associated with adverse cardiovascular outcomes and all-cause mortality after a follow-up period of 10 to 15 years. Furthermore, 0, 5 to 3 cups of coffee a day were independently associated with a lower risk of all-cause CV mortality [cardiovasculares] and stroke,” the authors said.
