V\u00fdskumn\u00edci z University of Oulu sa pozreli aj na metabolizmus a pohlavn\u00e9 horm\u00f3ny. Pr\u00e1ve pri horm\u00f3noch sa objavil zauj\u00edmav\u00fd rozdiel medzi mu\u017emi a \u017eenami,\u00a0p\u00ed\u0161e port\u00e1l MedicalXpress.<\/a><\/p>\n

Vedci analyzovali \u00fadaje od 2 264 \u013eud\u00ed, ktor\u00ed mali 46 rokov. V\u0161etci poch\u00e1dzali zo zn\u00e1mej f\u00ednskej kohorty Northern Finland Birth Cohort 1966. V\u00fdskumn\u00edci porovnali ich obvykl\u00fd pr\u00edjem k\u00e1vy s mno\u017estvom metabolitov v krvi, ukazovate\u013emi metabolick\u00e9ho zdravia a hladinami pohlavn\u00fdch horm\u00f3nov.<\/p>\n

Viac k\u00e1vy sa v \u0161t\u00fadii rovnalo menej tuku<\/p>\n

Jedn\u00fdm z najzauj\u00edmavej\u0161\u00edch v\u00fdsledkov sa stalo zlo\u017eenie tela. \u013dudia s vy\u0161\u0161ou spotrebou k\u00e1vy s\u00edce nemali v\u00fdrazne odli\u0161n\u00e9 BMI ako \u013eudia, ktor\u00ed jej pili menej, no ich telo malo in\u00e9 proporcie. V\u00fdskumn\u00edci zaznamenali ni\u017e\u0161ie mno\u017estvo celkov\u00e9ho tuku a tie\u017e menej viscer\u00e1lneho tuku. Ten sa nach\u00e1dza v okol\u00ed vn\u00fatorn\u00fdch org\u00e1nov a jeho nadbytok patr\u00ed medzi nepriazniv\u00e9 faktory spojen\u00e9 s metabolick\u00fdmi probl\u00e9mami. Skupina s vy\u0161\u0161ou spotrebou k\u00e1vy<\/a> mala z\u00e1rove\u0148 v\u00e4\u010d\u0161ie mno\u017estvo kostrov\u00e9ho svalstva.<\/p>\n

To je zauj\u00edmav\u00e9 najm\u00e4 preto, \u017ee samotn\u00e9 BMI tak\u00fdto rozdiel nemus\u00ed odhali\u0165.

Podobn\u00e1 s\u00favislos\u0165 sa objavila pri aminokyselin\u00e1ch s rozvetven\u00fdm re\u0165azcom, zn\u00e1mym ako BCAA. \u013dudia s vy\u0161\u0161\u00edm pr\u00edjmom k\u00e1vy mali v krvi ni\u017e\u0161ie koncentr\u00e1cie t\u00fdchto l\u00e1tok. Ich zv\u00fd\u0161en\u00e9 hladiny sa v minulosti sp\u00e1jali s inzul\u00ednovou rezistenciou a vy\u0161\u0161\u00edm rizikom cukrovky 2. typu.<\/p>\n

V\u00fdsledky teda nazna\u010dili s\u00favis medzi pravideln\u00fdm pit\u00edm k\u00e1vy, zlo\u017een\u00edm tela a niektor\u00fdmi metabolick\u00fdmi<\/a> ukazovate\u013emi.<\/p>\n

U mu\u017eov sa objavil v\u00fdraznej\u0161\u00ed hormon\u00e1lny rozdiel<\/p>\n

E\u0161te zauj\u00edmavej\u0161ia situ\u00e1cia nastala pri pohlavn\u00fdch horm\u00f3noch. Najv\u00fdraznej\u0161ie rozdiely vedci zaznamenali u mu\u017eov. Mu\u017ei s vy\u0161\u0161ou spotrebou k\u00e1vy mali priaznivej\u0161\u00ed profil gluk\u00f3zy a inzul\u00ednu<\/a>. Z\u00e1rove\u0148 mali vy\u0161\u0161ie koncentr\u00e1cie celkov\u00e9ho testoster\u00f3nu a biologicky dostupn\u00e9ho testoster\u00f3nu. Vy\u0161\u0161iu hladinu zaznamenali aj pri bielkovine SHBG, ktor\u00e1 v krvi via\u017ee pohlavn\u00e9 horm\u00f3ny a ovplyv\u0148uje mno\u017estvo horm\u00f3nov dostupn\u00fdch pre tkaniv\u00e1.<\/p>\n

Na prv\u00fd poh\u013ead v\u0161ak v\u00fdsledky pri testoster\u00f3ne m\u00f4\u017eu p\u00f4sobi\u0165 trochu protichodne. Hoci celkov\u00fd a biologicky dostupn\u00fd testoster\u00f3n dosiahol pri vy\u0161\u0161om pr\u00edjme k\u00e1vy vy\u0161\u0161ie hodnoty, vo\u013en\u00fd testoster\u00f3n a takzvan\u00fd vo\u013en\u00fd androg\u00e9nny index mali mierne ni\u017e\u0161ie hodnoty.<\/p>\n

U \u017eien vedci na\u0161li menej hormon\u00e1lnych s\u00favislost\u00ed. Aj v tejto skupine sa v\u0161ak vy\u0161\u0161ia spotreba k\u00e1vy sp\u00e1jala s vy\u0161\u0161ou hladinou SHBG a ni\u017e\u0161\u00edmi hodnotami niektor\u00fdch vo\u013en\u00fdch androg\u00e9nov. Ved\u00faci autor \u0161t\u00fadie Luca Verroest upozornil, \u017ee v\u00fdsledky uk\u00e1zali pomerne v\u00fdrazn\u00fd hormon\u00e1lny podpis, ktor\u00fd nezmizol ani po zoh\u013eadnen\u00ed BMI a \u010fal\u0161\u00edch faktorov \u017eivotn\u00e9ho \u0161t\u00fdlu.<\/p>\n

\u201ePrekvapilo n\u00e1s, \u017ee sme na\u0161li odli\u0161n\u00fd hormon\u00e1lny profil, ktor\u00fd pretrval aj po zoh\u013eadnen\u00ed BMI a \u017eivotn\u00e9ho \u0161t\u00fdlu. Niektor\u00e9 z t\u00fdchto s\u00favislost\u00ed sa navy\u0161e l\u00ed\u0161ili medzi mu\u017emi a \u017eenami,\u201c uviedol Verroest.<\/p>\n

Neznamen\u00e1 to, \u017ee k\u00e1va spa\u013euje tuk<\/p>\n

Pri podobn\u00fdch v\u00fdsledkoch je v\u0161ak d\u00f4le\u017eit\u00e9 zachova\u0165 ur\u010dit\u00fa opatrnos\u0165. \u0160t\u00fadia toti\u017e sledovala s\u00favislosti medzi spotrebou k\u00e1vy a biologick\u00fdmi ukazovate\u013emi. Ne\u0161lo o experiment, pri ktorom by vedci jednej skupine prik\u00e1zali pi\u0165 k\u00e1vu a druhej ju \u00faplne vynecha\u0165. V\u00fdsledky preto samy osebe nedokazuj\u00fa, \u017ee pr\u00e1ve k\u00e1va sp\u00f4sobila ni\u017e\u0161ie mno\u017estvo tuku<\/a>, vy\u0161\u0161iu svalov\u00fa hmotu alebo zmeny hlad\u00edn horm\u00f3nov.<\/p>\n

Do v\u00fdsledkov m\u00f4\u017eu vstupova\u0165 aj \u010fal\u0161ie faktory. \u013dudia, ktor\u00ed pij\u00fa viac k\u00e1vy, m\u00f4\u017eu ma\u0165 odli\u0161n\u00e9 stravovacie n\u00e1vyky, pohybov\u00fa aktivitu alebo \u010fal\u0161ie charakteristiky \u017eivotn\u00e9ho \u0161t\u00fdlu. V\u00fdskumn\u00edci s\u00edce viacer\u00e9 z nich zoh\u013eadnili, no pri observa\u010dnom v\u00fdskume sa nedaj\u00fa v\u0161etky mo\u017en\u00e9 vplyvy \u00faplne odstr\u00e1ni\u0165.<\/p>\n

Svoje v\u00fdsledky preto vedci vn\u00edmaj\u00fa sk\u00f4r ako z\u00e1klad pre \u010fal\u0161\u00ed v\u00fdskum. Zauj\u00edma ich najm\u00e4 ot\u00e1zka, \u010di niektor\u00e1 zo zlo\u017eiek k\u00e1vy priamo ovplyv\u0148uje metabolizmus a hormon\u00e1lnu rovnov\u00e1hu.<\/p>\n

\u201eSt\u00e1le vieme prekvapivo m\u00e1lo o tom, ako k\u00e1va s\u00favis\u00ed s na\u0161\u00edm metabolizmom a horm\u00f3nmi,\u201c povedal Verroest.<\/p>\n

V\u00fdskumn\u00edci u\u017e tieto ot\u00e1zky preveruj\u00fa aj v pokusoch na zvierat\u00e1ch. \u010eal\u0161\u00edm krokom by mohli by\u0165 kontrolovan\u00e9 \u0161t\u00fadie na \u013eu\u010foch, ktor\u00e9 by lep\u0161ie uk\u00e1zali, \u010di medzi k\u00e1vou a pozorovan\u00fdmi zmenami existuje skuto\u010dn\u00fd pr\u00ed\u010dinn\u00fd vz\u0165ah. F\u00ednsko je pritom na tak\u00fdto v\u00fdskum pomerne zauj\u00edmavou krajinou. Patr\u00ed toti\u017e medzi \u0161t\u00e1ty s najvy\u0161\u0161ou spotrebou k\u00e1vy na svete. Priemern\u00fd F\u00edn vypije mno\u017estvo k\u00e1vy zodpovedaj\u00face pribli\u017ene 11,8 kilogramu k\u00e1vy ro\u010dne.<\/p>\n

Nov\u00e9 v\u00fdsledky teda prid\u00e1vaj\u00fa \u010fal\u0161\u00ed dielik do sklada\u010dky okolo jedn\u00e9ho z najbe\u017enej\u0161\u00edch n\u00e1pojov.
