Pazite li na prehranu, velike su šanse da izbjegavate zamrznutu hranu jer vjerujete da ona smrzavanjem gubi na nutritivnoj vrijednosti. Ipak, rezultati istraživanja o svježoj i zamrznutoj hrani mogli bi vas iznenaditi, piše Alternativa za vas. 

Zamrznuta hrana može itekako biti bogata nutrijentima, ali opće je poznato da je prirodna i svježa hrana u pravilu zdravija i mnogo privlačnija za jelo. Nutritivna vrijednost ovisi o više različitih faktora, a zamrznuta hrana je ponekad bolja opcija. Evo koje savjete su ponudili kako bi vaš izbor bio čim logičniji: 

Kada kupujete svježe, birajte lokalno i sezonsko

Kupujete li svježu hranu, poput voća i povrća, u supermarketima, trebate znati da su ti plodovi često ubrani prije njihova sazrijevanja te da je njihov put do polica trgovina dugačak, osobito ako se radi o egzotičnom voću.

U tom slučaju možete biti sigurni da se više ne radi o „svježem“ voću i povrću i da u takvoj hrani ima vrlo malo nutritivnih vrijednosti.

Tijekom putovanja i duljeg, čak i višetjednog stajanja na policama, takve „svježe“ namirnice mogu izgubiti i do 50 posto svojih nutritivnih vrijednosti.

Čim se voće i povrće koje još nije dozrelo ubere, ono vrlo brzo počinje gubiti svoje hranjive tvari i antioksidanse.

Jeste li znali, primjerice, da špinat nakon što tjedan dana odstoji na sobnoj temperaturi izgubi 100 posto svog vitamina C? Ako je to vrijeme odležao u hladnjaku, izgubio je do 75 posto, a u zamrzivaču svega 30 posto tog važnog antioksidansa. Dakle, svježe nije nužno uvijek i bolje.

Što se tiče nabave svježeg voća i povrća, najbolje je imati vlastiti vrt ili pak kupovati lokalno uzgojeno voće i povrće, koje će na vaš stol stići vrlo brzo nakon branja ili vađenja iz zemlje.

I ne zaboravite da svježe uvijek jedete u vrijeme kada mu je sezona. U protivnom radije birajte zamrznuto. 

U brzo zamrznutom voću i povrću očuvana je većina nutrijenata

Voće i povrće koje se odabire za zamrzavanje bere se na vrhuncu svoje zrelosti i u roku od obično dva sata izlaže se procesu zamrzavanja.

Sve to kako bi se maksimalno očuvale nutritivne vrijednosti. Taj se postupak naziva proces brzog zamrzavanja.

Premda je točno da se neki nutrijenti, poput vitamina, oslabe i izgube tijekom zamrzavanja, većina njih se ipak dobro sačuva i ostaje „zaključana“ u zamrznutom plodu.

Istraživanja su pokazala da je zamrznuto povrće i voće ipak zdraviji izbor od onog koje je prošlo dugačak put zrakoplovom, brodom ili kamionom, a koje je nakon toga još odležalo neko vrijeme u skladištu ili na policama trgovina.

Također, zamrznuto voće i povrće je bolji izbor ako ga kupujete izvan sezone.

Studije govore u prilog zamrznute brokule, prokulica, čak i borovnica

Studija u kojoj su znanstvenici uspoređivali svježu i zamrznutu hranu pokazala je da su u zamrznutoj brokuli sačuvane veće razine vitamina C i beta-karotena.

Slično vrijedi i za zamrznute prokulice, u kojima su bolje sačuvani svi nutrijenti, baš kao i za zamrznute borovnice, u kojima ćete naći puno više polifenola i antocijanina nego u onima koje su odležale prije nego što su stigle do vašeg stola. 

Studija iz 2013. provedena na Sveučilištu Georgia pokazala je da prvog dana nakon kupnje i svježe i zamrznuto voće i povrće imaju približno jednake nutritivne vrijednosti.

No nakon pet dana stajanja u hladnjaku svježe voće i povrće ima manje vitamina C i A te niže razine folata nego što ih ima u onom zamrznutom.

Pazite li na prehranu, velike su šanse da izbjegavate zamrznutu hranu jer vjerujete da ona smrzavanjem gubi na nutritivnoj vrijednosti. Ipak, rezultati istraživanja o svježoj i zamrznutoj hrani mogli bi vas iznenaditi, piše Alternativa za vas. 

Zamrznuta hrana može itekako biti bogata nutrijentima, ali opće je poznato da je prirodna i svježa hrana u pravilu zdravija i mnogo privlačnija za jelo. Nutritivna vrijednost ovisi o više različitih faktora, a zamrznuta hrana je ponekad bolja opcija. Evo koje savjete su ponudili kako bi vaš izbor bio čim logičniji: 

Kada kupujete svježe, birajte lokalno i sezonsko

Kupujete li svježu hranu, poput voća i povrća, u supermarketima, trebate znati da su ti plodovi često ubrani prije njihova sazrijevanja te da je njihov put do polica trgovina dugačak, osobito ako se radi o egzotičnom voću.

U tom slučaju možete biti sigurni da se više ne radi o „svježem“ voću i povrću i da u takvoj hrani ima vrlo malo nutritivnih vrijednosti.

Tijekom putovanja i duljeg, čak i višetjednog stajanja na policama, takve „svježe“ namirnice mogu izgubiti i do 50 posto svojih nutritivnih vrijednosti.

Čim se voće i povrće koje još nije dozrelo ubere, ono vrlo brzo počinje gubiti svoje hranjive tvari i antioksidanse.

Jeste li znali, primjerice, da špinat nakon što tjedan dana odstoji na sobnoj temperaturi izgubi 100 posto svog vitamina C? Ako je to vrijeme odležao u hladnjaku, izgubio je do 75 posto, a u zamrzivaču svega 30 posto tog važnog antioksidansa. Dakle, svježe nije nužno uvijek i bolje.

Što se tiče nabave svježeg voća i povrća, najbolje je imati vlastiti vrt ili pak kupovati lokalno uzgojeno voće i povrće, koje će na vaš stol stići vrlo brzo nakon branja ili vađenja iz zemlje.

I ne zaboravite da svježe uvijek jedete u vrijeme kada mu je sezona. U protivnom radije birajte zamrznuto. 

U brzo zamrznutom voću i povrću očuvana je većina nutrijenata

Voće i povrće koje se odabire za zamrzavanje bere se na vrhuncu svoje zrelosti i u roku od obično dva sata izlaže se procesu zamrzavanja.

Sve to kako bi se maksimalno očuvale nutritivne vrijednosti. Taj se postupak naziva proces brzog zamrzavanja.

Premda je točno da se neki nutrijenti, poput vitamina, oslabe i izgube tijekom zamrzavanja, većina njih se ipak dobro sačuva i ostaje „zaključana“ u zamrznutom plodu.

Istraživanja su pokazala da je zamrznuto povrće i voće ipak zdraviji izbor od onog koje je prošlo dugačak put zrakoplovom, brodom ili kamionom, a koje je nakon toga još odležalo neko vrijeme u skladištu ili na policama trgovina.

Također, zamrznuto voće i povrće je bolji izbor ako ga kupujete izvan sezone.

Studije govore u prilog zamrznute brokule, prokulica, čak i borovnica

Studija u kojoj su znanstvenici uspoređivali svježu i zamrznutu hranu pokazala je da su u zamrznutoj brokuli sačuvane veće razine vitamina C i beta-karotena.

Slično vrijedi i za zamrznute prokulice, u kojima su bolje sačuvani svi nutrijenti, baš kao i za zamrznute borovnice, u kojima ćete naći puno više polifenola i antocijanina nego u onima koje su odležale prije nego što su stigle do vašeg stola. 

Studija iz 2013. provedena na Sveučilištu Georgia pokazala je da prvog dana nakon kupnje i svježe i zamrznuto voće i povrće imaju približno jednake nutritivne vrijednosti.

No nakon pet dana stajanja u hladnjaku svježe voće i povrće ima manje vitamina C i A te niže razine folata nego što ih ima u onom zamrznutom.

Pazite li na prehranu, velike su šanse da izbjegavate zamrznutu hranu jer vjerujete da ona smrzavanjem gubi na nutritivnoj vrijednosti. Ipak, rezultati istraživanja o svježoj i zamrznutoj hrani mogli bi vas iznenaditi, piše Alternativa za vas. 

Zamrznuta hrana može itekako biti bogata nutrijentima, ali opće je poznato da je prirodna i svježa hrana u pravilu zdravija i mnogo privlačnija za jelo. Nutritivna vrijednost ovisi o više različitih faktora, a zamrznuta hrana je ponekad bolja opcija. Evo koje savjete su ponudili kako bi vaš izbor bio čim logičniji: 

Kada kupujete svježe, birajte lokalno i sezonsko

Kupujete li svježu hranu, poput voća i povrća, u supermarketima, trebate znati da su ti plodovi često ubrani prije njihova sazrijevanja te da je njihov put do polica trgovi...
