                                            The dietary nitrate in plants is known to help the body dilate blood vessels, decrease blood pressure, increase oxygen delivery, reduce the perceived difficulty of exercise, and more. 
But, while beets are a particularly great source, seized upon as a marketable supplement choice (because, who wants to drink arugula juice?) plenty of other veggies provide nitrates too. A recent study showed this very nicely by giving people either daily beet juice or a box of fresh veggies (with recipes to try) and BOTH groups had decreased blood pressure after just 1 week! So eat your darn vegetables!
