 Ti z n\u00e1s, kte\u0159\u00ed nemaj\u00ed mo\u017enost si svoji zeleninu vyp\u011bstovat na zahr\u00e1dce, jsou odk\u00e1z\u00e1ni na n\u00e1kup bu\u010f \u010derstv\u00e9, nebo mra\u017een\u00e9 zeleniny, a v\u011bdeck\u00e9 v\u00fdzkumy ukazuj\u00ed, \u017ee v n\u011bkter\u00fdch p\u0159\u00edpadech m\u016f\u017ee b\u00fdt zelenina mra\u017een\u00e1 \u201ezdrav\u011bj\u0161\u00ed\u201c ne\u017e \u010derstv\u00e1.
 1) \u010cerstv\u00e1 zelenina se skl\u00edz\u00ed p\u0159edt\u00edm, ne\u017e uzraje, proto\u017ee se pos\u00edl\u00e1 \u010dasto na velk\u00e9 vzd\u00e1lenosti a skladuje se mnoho dn\u00ed v obchodech. P\u0159ed\u010dasn\u00e9 skl\u00edzen\u00ed zkracuje dobu, kterou zelenina pot\u0159ebuje pro maxim\u00e1ln\u00ed obsah \u017eivin. Mra\u017een\u00e1 zelenina se naopak skl\u00edz\u00ed zral\u00e1, v dob\u011b kdy obsahuje maxim\u00e1ln\u00ed mno\u017estv\u00ed vitamin\u016f. \u0160etrn\u00fdm rychlo-mra\u017een\u00edm se udr\u017euje pak vysok\u00fd obsah vitamin\u016f.
 2) D\u00edky \u0161patn\u00e9 pov\u011bsti mra\u017een\u00e9 zeleniny, pova\u017eujeme \u010derstvou zeleninu v\u017edy za \u201e\u010derstvou\u201c, ono je tomu ale paradoxn\u011b naopak.
 3) V p\u0159\u00edpad\u011b \u010derstv\u00e9 zeleniny je tady ot\u00e1zka dopravy \u2013 v\u011bt\u0161ina zeleniny neroste v na\u0161\u00ed republice, proto mus\u00ed b\u00fdt dov\u00e1\u017eena, b\u00fdv\u00e1 to v rozmez\u00ed dvou dn\u016f a\u017e dvou t\u00fddn\u016f, ne\u017e se dostane k z\u00e1kazn\u00edkovi, a nyn\u00ed si p\u0159edstavte, \u017ee po celou tu dobu je vystavena slunci, sv\u011btlu a kysl\u00edku, kolik v n\u00ed asi za tu dobu z\u016fstane vitam\u00edn\u016f a antioxidant\u016f?
 4) Oproti tomu mra\u017een\u00e1 zelenina je zpracov\u00e1na t\u00e9m\u011b\u0159 ihned po sklizni, to znamen\u00e1 v dob\u011b, kdy je p\u0159ipraven\u00e1 ke konzumaci. T\u011bsn\u011b p\u0159ed zmrazen\u00edm b\u00fdv\u00e1 je\u0161t\u011b o\u0161et\u0159ena p\u00e1rou, co\u017e je tzv. blan\u0161\u00edrov\u00e1n\u00ed.
 5) B\u011bhem t\u00e9 kr\u00e1tk\u00e9 doby, i kdy\u017e samoz\u0159ejm\u011b n\u011bkter\u00e9 vitam\u00edny ztrat\u00ed, v\u011bt\u0161inu si jich stihne mra\u017een\u00e1 zelenina uchovat, vzhledem k tomu m\u016f\u017ee mra\u017een\u00e1 zelenina obsahovat v\u00edce stopov\u00fdch prvk\u016f a vitam\u00edn\u016f NE\u017d zelenina \u010derstv\u00e1.
