What compound are dietary nitrates naturally occurring in spinach converted into by the body to aid in blood pressure regulation?
Answer
Nitric oxide
Spinach is noted for its rich concentration of dietary nitrates, which are naturally present compounds that the body processes internally. These nitrates undergo a conversion into nitric oxide. Nitric oxide functions as a potent vasodilator, meaning its primary effect on the cardiovascular system is to help relax and widen the blood vessels. This widening action directly results in lowered blood pressure, which plays a significant role in mitigating the risk factors associated with heart disease and stroke.
