Ezinye iimveliso zinokuba nempikiswano ngokuxhomekeke kwindlela ezibonwa ngayo ngamaqela athile abantu. Amaqela amabini abantu abona izithako ezifana ne-cilantro ngokwahlukileyo: abantu abaye bazama i-cilantro kunye nabantu abaye bazama isepha. Ngokufanayo, abanye abantu bayakuphepha ukutya i-asparagus kuba inokuchaphazela ivumba lomchamo wabo. Okunye ukutya okuphikiswana ngako onokuthi ungazazi yi-spinach.

Ispinatshi ine-asidi eninzi ye-oxalic acid echasene nezakhamzimba. I-Modern Smile ichaza ukuba i-asidi ye-oxalic yindlela yokuzikhusela yesipinatshi kwizilwanyana ezizingelayo. Xa utya isipinatshi esiluhlaza, umlomo wakho uyasabela. Xa iiseli zesipinatshi ziqhekeka, i-asidi ye-oxalic iyakhutshwa, nto leyo ethintela ukufunxwa kwe-calcium. Amathe akho ane-calcium encinci, ngoko ke xa uqala ukuqhekeza isipinatshi, i-asidi ye-oxalic kunye ne-calcium ziyadibana zenze iikristale ezincinci ze-calcium oxalate. Ezi kristale zincinci zibangela uvakalelo olungathandekiyo kunye nokuthungwa okurhabaxa.
Nangona abantu abaninzi befumana imvakalelo efana netshokhwe, iziphumo ze-oxalic acid kwispinatshi azikafundwa okwangoku.

Oku kucetyiswa ngakumbi ukuba uceba ukongeza ispinatshi kwizitya ezikhrimu, ezifana nespinatshi ekhrimu. Ukupheka ispinatshi ngebhotolo okanye ikhrimu kunokwenza ukuba impendulo ibe mandundu. Ukuba ufuna ukutya ispinatshi iluhlaza, cinezela ijusi yelamuni encinci kumagqabi espinatshi ukunciphisa ukungonwabi. I-asidi ekwiilamuni iyaqhekeza i-oxalic acid.
