nitrates

A family of chemically stable forms of inorganic nitrogen, which are formed as part of the natural breakdown of organic matter. Nitrates are ingested in vegetables and absorbed from the gastrointestinal tract; an estimated 25% of absorbed nitrates are released into the saliva, 20% of which are converted into nitrites. Nitrates are manufactured for use as fertilisers and explosives and tend to accumulate in the environment, as the uptake of nitrates by plants is relatively slow.

Nitrates turn to nitrites when they reached the mouth or stomach then turn into nitric oxide, which can be good, and nitrosamines, which can be bad for our bodies.
Nitrate contents are higher in stems of numerous fodder crops than in leaves, as those parts which are closer to the ground contain more nitrates; roots and stem typically have higher nitrate levels, followed by leaves (Westcott et al., 1998; Malagoli et al., 2005; Qiu et al., 2014).
