What molecule results from the conversion of dietary nitrates in the body to signal blood vessels to relax and widen?
Nitric oxide (NO)
The primary mechanism by which beets influence cardiovascular health involves dietary nitrates. These naturally occurring nitrates, which are highly concentrated in beets, undergo a conversion process within the body. This chemical transformation results in the production of nitric oxide, abbreviated as NO. Nitric oxide acts as a potent signaling molecule that directs the smooth muscles surrounding the arteries and blood vessels to relax. This relaxation causes the vessels to widen, a process known scientifically as vasodilation. Increased vessel diameter directly leads to a measurable reduction in blood pressure, affecting both systolic and diastolic readings.
