Beetroot Juice Linked to Lower Blood Pressure in Seniors

A University of Exeter study found older adults who drank nitrate-rich beetroot juice for two weeks experienced a drop in blood pressure, an effect not observed in younger participants, possibly due to age-related declines in nitric oxide production and changes in mouth bacteria that process nitrates. The findings suggest dietary nitrates from vegetables could support cardiovascular health but are not a substitute for medication, and larger trials are needed; other nitrate-rich foods like spinach and kale may offer similar benefits.
