spinach, well but must know farther

After try to plant spinach since may month, i so to learn more about spinach. also after harvest at home and make spinach clear vegetable, very seen that spinach the colour very green clear and bright. usually if the colour spinach can rather old green. obvious there are some explanation.

1.       spinach contains ferrum that is fe2+ (ferro). when does spinach too long contact with o2 (oxygen from air), fe2+ oxidation will be fe3+ (ferri). although same ferrum, good for we are ferro. ferri has toxic in spinach. obvious, if spinach is heated, so spinach oxidation so that spinach, cah or clear spinach vegetable doesn't finished don't heated. therefore ripe spinach sufficient.       

2.       ripe spinach before 5 clocks. besides contain substance at mention a while ago that, also contain nitrate substance (NO3). moment oxidation, NO3 will be NO2 (nitrit). nitrit compound not coloured, odourless,  and has poison for human body. fresh spinach bew has been pulled contain compound nitrit approximately as much as 5 mg/kg. when is spinach kept at refrigerator during 2 weeks, degree nitrit will increase until 300 mg/kg. equally, in 1 storage day, compound nitrit will increase 21 mg/kg (7%). toxic effect (poisons body) that evoked by nitrit start from oxidation reaction nitrit with ferrum in red corpuscle, precisely in Hemoglobin (Hb). tie nitrit with haemoglobin, called methemoglobin, cause hemoglobin doesn't can to tie up oxygen. if total methemoglobin achieve more than 15% from hemoglobin total, so will happen conditon that called sianosis, that is a where entire oxygen deficit human body networks.          

3.       ferrum in spinach pregnancy even also can react with alluminium ingredient and produce poison, therefore koid to cook spinach with alluminium pan.

but, spinach as choice food popeye, also very salubrious. rich spinach leaf nutrition, such as those which mentioned on, that is ferrum that need body to stimulate red corpuscle formation. consuming spinach vegetable same mean with protect self from disease phenomenons less blood that make body are choked/weak. spinach leaf good to kidney and digestion organ by because the fiber pregnancy enough tall so that can overcome constipation and launch to defecate. nutrition pregnancy exist in spinach can demote cholesterol, blood sugar, launch blood circulation and demote blood pressure that over do. spinach can be intestines cancer preventative vegetable, diabetes, fail kidney, fall of hair, cataract and xeropthalmia. but spinach not for tendon sour sufferer and rhematik because spinach contains substance purin with degree enough tall and changed by body is sour tendon. this condition can trigger suffer a relapse it disease with pain phenomenon at hand hinge and foot.

I am taste all spinaches kindness exceed the deficit so that this information even also can inspire you that love to eat spinach to plant self at home so that can always be spinach be be picked and still fresh direct cultivated. besides don't too long keep spinach in refrigerator.
