10. Arugula
Arugula is a leafy green from the Brassicaceae family that goes by many different names, such as rocket, colewort, roquette, rucola and rucoli.
It has a slightly peppery taste and small leaves that can easily be incorporated into salads or used as a garnish. It can also be used cosmetically and medicinally (30Trusted Source).
Like other leafy greens, it’s packed with nutrients such as pro-vitamin A carotenoids and vitamins B9 and K (31).
It’s also one of the best sources of dietary nitrates, a compound that turns into nitric oxide in your body.
Though the benefits of nitrates are debated, some studies have found that they may help increase blood flow and reduce blood pressure by widening your blood vessels (32Trusted Source).
