For a study published this month in the journal Clinical Nutrition ESPEN (published by the Clinical Society of European Nutrition and Metabolism), researchers from Greece and Algeria—all specializing in cardiovascular health or nutrition—started off by recognizing that regular coffee consumption is associated with lower risk of cardiovascular disease.
The focus of this particular study was to examine the effects of instant coffee on the development of heart disease. To do this, the researchers collected data from 1,041 male and female participants between the ages of 39 and 67 (with an average age of 53.6 years). Of this sample, the researchers report that 30% of individuals “habitually consumed instant coffee.”
In an initial calculation, they found that the consumers of instant coffee showed lower systolic blood pressure. (However, after adjusting for several factors, the research team discovered perhaps this was not a totally surefire measure.)
Additionally, they discovered that instant coffee consumption was associated with carotid arterial compliance (which, according to a 2008 study published in Nature, is healthy elasticity in the carotid artery, serving as a marker of cardiovascular wellness).
In conclusion, the researchers in the current study report that “habitual moderate instant coffee consumption” is associated with elasticity in the arteries—and therefore may also be associated with a lower incidence of cardiovascular disease.
