HealthDay News — Consumption of espresso is associated with increased serum total cholesterol (S-TC), with a stronger association seen for men than women, according to a study published online May 10 in Open Heart.

Åsne Lirhus Svatun, from the University of Norway in Tromsø, and colleagues used cross-sectional population data from the seventh survey of the Tromsø Study in Northern Norway, with 21,083 participants, aged 40 years or older, to examine how various brewing methods, in particular espresso, were associated with S-TC.

The researchers found that compared with participants drinking no cups of espresso per day, consumption of 3 to 5 cups of espresso daily was significantly associated with increased S-TC in women and men (0.09 and 0.16mmol/L, respectively). Compared with drinking no cups of boiled/plunger coffee, consumption of 6 or more cups of boiled/plunger coffee daily was associated with increased S-TC for women and men (0.30 and 0.23mmol/L, respectively). For women, but not men, consumption of 6 or more cups of filtered coffee daily was associated with 0.11mmol/L higher S-TC. A significant linear trend was seen for instant coffee consumption, but no dose-response relationship was seen when excluding participants not drinking instant coffee. For all coffee types except boiled/plunger coffee, sex differences were significant.

“The main finding in the present study was that espresso coffee was associated with increased S-TC,” the authors write. “Further research regarding espresso would be beneficial to review these new findings.”
