This seems counterintuitive so ask your doctor to delve into the details of the research.
Tea and coffee lower blood pressure in large French registry
A large French retrospective analysis provides good news for caffeine
lovers: investigators showed that drinking tea or coffee was associated
with a small but statistically significant reduction in systolic and
diastolic blood pressure. In addition, drinking tea and coffee was also
associated with a significant reduction in pulse pressure and heart
rate, although the heart-rate reductions were greater with tea.
Presenting the results at the European Society of Hypertension (ESH) 2013 Scientific Sessions, Dr Bruno Pannier
(Centre d'Investigations Préventives et Cliniques, Paris, France) said
that other studies have suggested a relationship between coffee and tea
consumption and blood pressure, but these analyses haven't been
conclusive. Some have suggested a benefit, while others found no
relationship between tea/coffee consumption and blood pressure.
Presenting the data on 176 437 subjects aged
16 to 95 years of age who had a checkup at their center between 2001 and
2011, Pannier explained that the analysis was simply based on a
questionnaire asking participants how much coffee or tea they drank per
day. Individuals were classified into three groups: those who drank no
coffee/tea, those who drank one to four cups, and those who drank more
than four cups.
Overall, coffee is consumed more frequently
than tea, although there were differences between the sexes, said
Pannier. Men were more likely to drink coffee, while women were more
commonly tea drinkers. Coffee consumption was also significantly
associated with tobacco consumption, higher cholesterol levels, and
higher scores on stress and depression indexes. Tea consumption, on the
other hand, was associated with lower cholesterol levels but similarly
high scores on the stress and depression measurements.
