Serving and storage
In addition to health benefits of spinach above, there are some points that we should pay attention about spinach serving and storage. Spinach contains iron in the form of Fe2 + (ferrous), if spinach too long to interact with O2 (Oxygen), the content of Fe 2 + in the spinach will be oxidized become Fe 3 + (ferric). Although both are the same iron compound, which is beneficial to humans is ferrous, ferric another case with a toxic. So, never to heat the spinach that has been cooked in the form of food.
It is recommended to consume spinach shortly after cooking, avoid eating spinach that has more than 5 hours on the dining table. Because in addition contains ferric, spinach may also contain substances nitrate (NO3), which when oxidized by air will also be NO2 (nitrite) compounds that are colorless, odorless and poisonous.
In the process of storage in the refrigerator must also be considered, because the longer spinach stored in the refrigerator, nitrite compound levels will continue to rise.
