Krom (Cr) je mineral v sledovih, ki \u2013 \u010deprav ga potrebujemo le v mikro koli\u010dinah \u2013 igra klju\u010dno vlogo pri tem, kako telo presnavlja hrano. Njegova primarna funkcija je tesno povezana z delovanjem inzulina, zato velja za enega pomembnih dejavnikov pri prepre\u010devanju sodobnih presnovnih motenj.<\/p>\n\n\n\n

Vloga v organizmu<\/p>\n\n\n\n

Najpomembnej\u0161a vloga kroma v \u010dlove\u0161kem telesu je tvorba molekule, imenovane kromodulin. Ta molekula pomaga inzulinu, da se ve\u017ee na receptorje na povr\u0161ini celic.<\/p>\n\n\n\n

Biolo\u0161ko aktivna oblika kroma sodeluje pri presnovi glukoze tako, da okrepi delovanje inzulina. Inzulin izlo\u010dajo specializirane celice v trebu\u0161ni slinavki kot odziv na povi\u0161ano raven glukoze v krvi. Inzulin se ve\u017ee na inzulinske receptorje na povr\u0161ini celic, kar aktivira receptorje in spodbuja vstop glukoze v celice. Tako inzulin oskrbi celice z glukozo, potrebno za proizvodnjo energije, in prepre\u010duje pretirano zvi\u0161anje ravni glukoze v krvi. Poleg vpliva na presnovo ogljikovih hidratov (glukoze) inzulin vpliva tudi na presnovo ma\u0161\u010dob in beljakovin.<\/p>\n\n\n\n

\u2022 Izbolj\u0161anje ob\u010dutljivosti na inzulin: <\/strong>predstavljajte si inzulin kot klju\u010d, ki odpira vrata celic, da sladkor (glukoza) vstopi. Krom deluje kot \u00bbmazivo\u00ab, ki omogo\u010da, da se klju\u010d la\u017eje in hitreje obrne v klju\u010davnici.
\u2022 Energija: <\/strong>zaradi kroma se glukoza u\u010dinkoviteje uporablja za proizvodnjo energije v mi\u0161icah in mo\u017eganih, namesto da bi se shranjevala v obliki ma\u0161\u010dobnih zalog.<\/p>\n\n\n\n

Vpliv na presnovo in prebavo<\/p>\n\n\n\n

Krom ni neposredno vklju\u010den v mehansko prebavo v \u010drevesju, je pa nepogre\u0161ljiv za presnovno obdelavo hranil <\/strong>potem, ko preidejo v krvni obtok:<\/p>\n\n\n\n

\u2022 Presnova ogljikovih hidratov:<\/strong> s stabilizacijo krvnega sladkorja krom pomaga zmanj\u0161ati \u00bbnapade lakote\u00ab in \u017eeljo po sladkem, kar je pomembno za vzdr\u017eevanje zdrave telesne mase.
\u2022 Presnova ma\u0161\u010dob: <\/strong>raziskave ka\u017eejo, da ustrezen vnos kroma lahko pomaga uravnavati lipide \u2013 zni\u017euje raven \u00bbslabega\u00ab LDL holesterola in zvi\u0161uje raven \u00bbdobrega\u00ab HDL holesterola.
\u2022 Presnova beljakovin: <\/strong>sodeluje pri transportu aminokislin v sr\u010dno mi\u0161ico in druge organe ter podpira regeneracijo tkiv.<\/p>\n\n\n\n

Potrebe po kromu<\/p>\n\n\n\n

V skladu s pravilnikom o prehranskih dopolnilih priporo\u010deni vnos kroma za odrasle zna\u0161a 40 \u00b5g<\/strong>. Najvi\u0161ji dovoljeni vnos kroma po istem pravilniku zna\u0161a 150 \u00b5g.<\/p>\n\n\n\n

Viri kroma v prehrani<\/p>\n\n\n\n

Krom je v prehrani \u0161iroko raz\u0161irjen, vendar se pojavlja v relativno majhnih koli\u010dinah. Dobri viri kroma so meso (svinjina, govedina, puran), polnovredna \u017eita in za\u010dimbe (cimet, lovor, kurkuma, klin\u010dki). Dobri viri so tudi pivski kvas, gobe, siri, brokoli, \u0161parglji, krompir, grah, \u010debula, \u010desen, \u0161pina\u010da, paradi\u017enik, sok grenivke, pomaran\u010dni sok, temna \u010dokolada, rde\u010de vino, pivo, jabolka, slive in banane. Koli\u010dine kroma v \u017eivilih pa se razlikujejo in so odvisne od kmetijskih ter proizvodnih procesov.<\/p>\n\n\n\n

Krom se absorbira v majhnih koli\u010dinah, na biolo\u0161ko razpolo\u017eljivost pa vpliva ve\u010d dejavnikov. Pokazalo se je, da askorbinska kislina (vitamin C) in oksalati pove\u010dajo absorpcijo kroma, medtem ko fitati absorpcijo ovirajo. Prav tako lahko enostavni sladkorji pove\u010dajo izlo\u010danje kroma iz telesa.<\/p>\n\n\n\n

\u010ceprav ga organizem potrebuje le v sledovih, je krom pomemben regulator presnove makrohranil. Njegova vloga pri izbolj\u0161anju ob\u010dutljivosti celic na inzulin ga postavlja med klju\u010dne dejavnike pri ohranjanju stabilne ravni glukoze v krvi. Uravnote\u017een vnos tega minerala \u2013 bodisi z raznoliko prehrano, bogato s polnovrednimi \u017eivili, bodisi z namensko suplementacijo \u2013 predstavlja pomemben korak pri prepre\u010devanju sodobnih presnovnih izzivov.<\/p>\n\n\n\n
