"Nitric oxide (NO) is most important vasodilator (dilates arteries) in humans. Plants contain nitrates (NO3) & tongue bacteria convert it to nitrite (NO2). Then stomach acid converts it to NO. NO is then absorbed into the blood. Anything that decreases tongue bacteria, or stomach acid production, will lead to lower blood levels of nitric oxide. Lack of nitric oxide is associated with high blood pressure."

"Has Dr Esselstyn lost his mind? Is he senile? He's about 90 years old. Can't expect much from an old codger like that. Or is he a genius? Is he on to something with this eat 6 servings of greens at separate times every day? Does this really work to keep your arteries bathed in nitric oxide? Sounds like a pain in the butt to do this."
