Given this information is very important for health, especially for those who like vegetables spinach in this case, posting the following email I received in my email inbox. Hopefully useful.
For those of you who like spinach, identify any matters contained in it from start harvesting until cooked to be able to serve it properly. * Spinach contains iron in the form of Fe2 + (ferrous) ALREADY know right? If he's too long a contact with O2 (Oxygen), Fe2 + will be oxidized to Fe3 + (ferric). Although both iron, which is useful for us there is ferrous. While the ferric character of toxid in spinach.SO .. If spinach is heated, it will apply oxidation. (I'm confused why my mother always used to heat the spinach ban, always say "spinach, if not expired should not be heated again") * Never eat spinach more than 5 hours. You see, spinach also contains nitrate (NO3). When oxidized with air, it would be NO2 (Nitrite). Nitrite is a compound that is colorless, odorless and are toxic to the human body. http://www.biomedexperts.com/Profile.bme/1546449/John_S_WishnokAccording to John S Wishnok, fresh spinach has been removed nitrite compounds containing approximately 5 mg / kg. When the spinach is stored in the refrigerator for 2 weeks, nitrite levels will rise to 300 mg / kg. In other words, within 1 day of storage, nitrite compounds will increase to 21 mg / kg (7%). Toxic effects (poisoning the body) caused by Nitrite Nitrite oxidation reaction begins with the iron in red blood cells, specifically in the hemoglobin (Hb). Maybe there who do not know that one task is to bind hemoglobin oxygen to be distributed to all organs of the body. Nitrite bond with hemoglobin, called Methemoglobin, resulting in hemoglobin can not bind oxygen. If the amount of methemoglobin reach more than 15% of total hemoglobin, there will be a condition called Cyanosis, a condition in which the whole body tissue of oxygen deficiency. IF this happens to a baby known as "Blue Baby". Other toxic effects is the ability to react with nitrite to form a secondary amino compounds that can cause cancer.
Remember, do not cook spinach disposable aluminum pans, because it can react with iron in spinach, and can be toxic.
