Leafy Greens

Organic leafy greens are without a doubt the best source of dietary nitrate. Nitrates are found in leafy green vegetables such as spinach, arugula, kale, and cabbage, which are converted to nitric oxide in the body.

According to one study, consuming nitrate-rich foods like green leafy vegetables on a daily basis will help maintain enough nitric oxide levels in the blood and tissues. One research found that having a nitrate-rich meal with spinach boosted salivary nitrate levels eightfold and reduced systolic blood pressure considerably. Consumption of high-nitrate leafy greens has also been linked to a lower risk of heart disease and cognitive decline in other studies. Some of the best leafy greens to eat are Arugula, Kale, Spinach, Spirulina, Swiss Chard, Cabbage, etc.
