Regular coffee consumption lowers blood pressure in adults.

Is it true that regular coffee consumption lowers blood pressure in adults?

Partly. Two analyses of the Brisighella Heart Study cohort and one Japanese study of middle-aged men report that regular coffee drinking is associated with lower systolic blood pressure, while an older review reports that acute caffeine raises blood pressure and that chronic intake produces at most marginal changes. The evidence is limited to specific cohorts and observational associations, so it only partially addresses the general claim.
