Espresso coffee is associated with an increase in total cholesterol

Espresso consumption suggests a population-based, cross-sectional study related to high levels of total cholesterol.

Elevated total serum cholesterol levels were significantly associated with espresso consumption, especially in men, including Asne Lirhus Swatun of Arctic University in Tromso, Norway, and colleagues.

Drinking brewed / piston coffee is associated with significantly higher total serum cholesterol levels in women and men. There is a significant association between filtered coffee consumption and total cholesterol, but only among women, the researchers report.

Dr. Maja-Lisa Lohen, a doctor at the University of the Arctic in Norway, said in an email: “Physicians should keep in mind the question of coffee consumption when researching the history of patients with elevated cholesterol levels.”

“Guiding patients to switch from piston coffee or other unfiltered coffee to filtered or instant coffee may be part of a lifestyle intervention to lower blood cholesterol levels.”

The results were published online in the magazine on May 10 open heart.

Researchers note that previous studies on the relationship between cholesterol and espresso have yielded mixed results.

Given that coffee consumption is high worldwide, it can have serious health consequences, albeit to a lesser extent, the researchers said. “Coffee was first included in the 2021 ESC [European Society of Cardiology] “Guidelines for the Prevention of Cardiovascular Disease in Clinical Practice,” they write. “Increasing knowledge about the relationship between espresso coffee and whey cholesterol will improve recommendations for coffee consumption.”

“I don’t think the findings in this paper are enough to change any advice about coffee,” said David Cao, an associate professor of medicine at the University of Colorado Anshutz Medical Campus in Denver, commenting on the results. . “This is partly because the most important thing at the end of the day is whether subsequent events such as heart attacks or strokes will increase or decrease. This analysis is not designed to answer this question,” he said.

“If someone has to choose between this study, they recommend drinking less coffee to lower their cholesterol levels, and if they think that increasing coffee reduces the risk of getting multiple types of CVD, they should choose the latter,” Kao concluded. .

In the current study, investigators estimated 21,083 participants in the Tromso study in northern Norway. The average age of participants was 56.4 years. Using multivariate linear regression, the researchers compared the relationship between each level of coffee consumption with coffee consumption as a reference point and total cholesterol as a dependent variable. They checked for gender differences and corrected for appropriate covariates.

Studies have shown that drinking three to five cups of espresso per day in men is 0.16 mmol / l (95% CI, 0.07 – 0.24) and 0.09 mmol / l (95% CI, 0.01 -) in the serum. shows that it is significantly associated with high cholesterol. 0.17) for women compared to participants who did not drink espresso daily.

Drinking six or more cups of plunger / brewed coffee per day was associated with an increase in total serum cholesterol levels of 0.23 mmol / l (95% CI, 0.08 – 0.38) in men compared to those who did not drink plunger / brewed coffee. 0.30 mmol / l for women (95% CI, 0.13 – 0.48).

It should be noted that with the consumption of six or more cups of filtered coffee per day for women, but not for men, the total cholesterol in the serum increased by 0.11 mmol / l (95% CI, 0.03 – 0.19).

With the exception of participants who did not drink instant coffee, instant coffee drinking provided a significant linear model for men and women, but was not dose-dependent.

These data suggest that gender differences were significant for each type of coffee except plunger / brewed coffee, the authors note.

The limitations of the study include the design of its cross section; Lack of data aggregation, given that the cohort consists mainly of older people and middle-aged whites; and that the study is not valid for all confusing variables, the researchers note.

Among the study’s limitations, the authors added, some data were self-reported and an insufficient indicator approach was used to evaluate the data.

Future research efforts should focus on following this cohort for many years to determine how consumption of different types of coffee is associated with events such as heart failure, stroke, and myocardial infarction. This concept would be important to provide guidance on whether or not the style of coffee making is important, Kao concluded.

The study was supported by a number of sources, including the Norwegian Arctic University and the Northern Norwegian Regional Health Authority. Svatun and Løchen report on the respective financial relationships.
