The nitrate-nitrite-nitric oxide pathway elevates nitric oxide through the sequential reduction of dietary nitrate derived from plant-based foods. [13] Nitrate-rich vegetables, in particular leafy greens, such as spinach and arugula , and beetroot , have been shown to increase cardioprotective levels of nitric oxide with a corresponding ...
Phototoxicity, also called photoirritation, is a chemically induced skin irritation, requiring light, that does not involve the immune system. [1] It is a type of photosensitivity.

Most side effects are direct consequences of the vasodilation and the resultant low blood pressure. They include headache ("nitrate headache") resulting from the widening of blood vessels in the brain, reflex tachycardia (fast heart rate), flush, dizziness, nausea and vomiting. These effects usually subside after a few days if the treatment is ...
Approximately 78% of Earth's atmosphere is N gas (N 2), which is an inert compound and biologically unavailable to most organisms.In order to be utilized in most biological processes, N 2 must be converted to reactive nitrogen (Nr), which includes inorganic reduced forms (NH 3 and NH 4 +), inorganic oxidized forms (NO, NO 2, HNO 3, N 2 O, and NO 3 −), and organic compounds (urea, amines, and ...
The combination of table salt with nitrates or nitrites, called curing salt, is often dyed pink to distinguish it from table salt. [7] Neither table salt nor any of the nitrites or nitrates commonly used in curing (e.g., sodium nitrate [NaNO 3], [8] sodium nitrite, [8] and potassium nitrate [9]) is naturally pink.
Nitrates used in agricultural fertilizers may leak into the ground and may contaminate well water. The current EPA standard of 10 ppm nitrate-nitrogen for drinking water is specifically set to protect infants. [13] Benzocaine applied to the gums or throat (as commonly used in baby teething gels, or sore throat lozenges) can cause methemoglobinemia.
