Nitrate is essential in many natural processes, including plant development. It is crucial in nature; however, it is also critical for human health and nutrition, from its presence in foods such as leafy greens and root vegetables which can serve as notable sources containing high nitrate levels thus if consumed excessively it can lead to possible health consequences. Due to the differences in metabolic capacity, the daily nitrate consumption guidelines for adults and newborns differ. Furthermore, infants that consume an overabundance of nitrate, particularly from drinking water or baby foods, are at risk of experiencing methemoglobinemia, a condition referred to as "blue baby syndrome." This occurs when nitrate interferes with the blood's capacity to carry oxygen, resulting in a diminished delivery of oxygen to essential organs. Symptoms involve bluish skin coloring, difficulty in breathing, fatigue, and in extreme instances, death.
