Resveratrol<\/u><\/a> je antioxidant, kter\u00fd se nach\u00e1z\u00ed ve slupce \u010derven\u00fdch hrozn\u016f. Bylo provedeno mnoho studi\u00ed zam\u011b\u0159en\u00fdch na p\u0159\u00ednosy resveratrolu, kter\u00e9 zjistily, \u017ee pravideln\u00e1 konzumace tohoto antioxidantu m\u016f\u017ee sn\u00ed\u017eit riziko srde\u010dn\u00edch onemocn\u011bn\u00ed t\u00edm, \u017ee sni\u017euje krevn\u00ed tlak. D\u016fvodem je to, \u017ee resveratrol stimuluje tvorbu oxidu dusnat\u00e9ho v c\u00e9v\u00e1ch, \u010d\u00edm\u017e podporuje jejich rozta\u017een\u00ed a zp\u016fsobuje pokles krevn\u00edho tlaku.<\/p>\n\n\n\nV jednom litru \u010derven\u00e9ho v\u00edna najdete mezi 0,2 a 5,8 mg resveratrolu. To je obvykle v\u00edce, ne\u017e z\u00edsk\u00e1te z konzumace syrov\u00fdch hrozn\u016f, proto\u017ee p\u0159i v\u00fdrob\u011b \u010derven\u00e9ho v\u00edna doch\u00e1z\u00ed ke koncentraci resveratrolu. Stoj\u00ed za zm\u00ednku, \u017ee b\u00edl\u00e9 a r\u016f\u017eov\u00e9 v\u00edno obsahuj\u00ed mnohem m\u00e9n\u011b resveratrolu.<\/p>\n\n\n\n
N\u011bkter\u00e9 teorie nazna\u010duj\u00ed, \u017ee resveratrol obsa\u017een\u00fd v \u010derven\u00e9m v\u00edn\u011b m\u016f\u017ee b\u00fdt p\u0159\u00ed\u010dinou \u201efrancouzsk\u00e9ho paradoxu\u201c \u2013 tedy skute\u010dnosti, \u017ee Francouzi trp\u00ed srde\u010dn\u00edmi chorobami relativn\u011b z\u0159\u00eddka, a to i p\u0159es stravu s vysok\u00fdm obsahem nasycen\u00fdch tuk\u016f. Jin\u00ed v\u0161ak tvrd\u00ed, \u017ee p\u0159\u00ed\u010dinou mohou b\u00fdt jin\u00e9 stravovac\u00ed n\u00e1vyky a \u017eivotn\u00ed styl.<\/p>\n\n\n\n
O resveratrolu se objevily i dal\u0161\u00ed tvrzen\u00ed t\u00fdkaj\u00edc\u00ed se zdrav\u00ed, od jeho schopnosti zvr\u00e1tit st\u00e1rnut\u00ed a\u017e po schopnost bojovat proti cukrovce, ale d\u016fkazy pro tato tvrzen\u00ed nejsou tak siln\u00e9.<\/p>\n\n\n\n
A co vliv alkoholu?<\/h2>\n\n\n\n
\u010cerven\u00e9 v\u00edno je alkoholick\u00fd n\u00e1poj a nen\u00ed sporu o tom, \u017ee alkohol p\u0159edstavuje zdravotn\u00ed riziko. Konzumace i mal\u00e9ho mno\u017estv\u00ed alkoholu m\u016f\u017ee zv\u00fd\u0161it riziko vzniku n\u011bkter\u00fdch druh\u016f rakoviny. Nadm\u011brn\u00e9 pit\u00ed alkoholu je zase spojov\u00e1no s onemocn\u011bn\u00edm jater, zat\u00edmco konzumace alkoholick\u00fdch n\u00e1poj\u016f p\u0159ed span\u00edm m\u016f\u017ee zhor\u0161ovat kvalitu sp\u00e1nku.<\/p>\n\n\n\n
A co zdrav\u00ed srdce? Mnoho studi\u00ed zjistilo, \u017ee konzumace alkoholick\u00fdch n\u00e1poj\u016f m\u016f\u017ee zv\u00fd\u0161it krevn\u00ed tlak \u2013 z\u00e1le\u017e\u00ed v\u0161ak na tom, kolik vypijete. Obvykle dojde k kr\u00e1tkodob\u00e9mu zv\u00fd\u0161en\u00ed krevn\u00edho tlaku po vypit\u00ed v\u00edce ne\u017e 3 sklenic. Pravideln\u00e1 konzumace 4 nebo v\u00edce sklenic najednou m\u016f\u017ee mezit\u00edm v\u00e9st k trvale vysok\u00e9mu krevn\u00edmu tlaku.<\/p>\n\n\n\n
To znamen\u00e1, \u017ee pokud pijete \u010derven\u00e9 v\u00edno pravideln\u011b ve velk\u00e9m mno\u017estv\u00ed, jak\u00e9koli p\u0159\u00ednosy pro zdrav\u00ed srdce budou pravd\u011bpodobn\u011b vyv\u00e1\u017eeny.<\/p>\n\n\n\n
Tak\u2026 je to dobr\u00e9, nebo \u0161patn\u00e9?<\/h2>\n\n\n\n
\u010cerven\u00e9 v\u00edno m\u016f\u017ee b\u00fdt prosp\u011b\u0161n\u00e9 pro va\u0161e srdce, pokud ho konzumujete s m\u00edrou. To znamen\u00e1, \u017ee byste nem\u011bli vyp\u00edt celou l\u00e1hev najednou a m\u011bli byste si pravideln\u011b dop\u0159\u00e1vat dny bez alkoholu (nebo je\u0161t\u011b l\u00e9pe \u2013 t\u00fddny bez alkoholu).<\/p>\n\n\n\n
Nezapome\u0148te, \u017ee \u010derven\u00e9 v\u00edno s sebou nese ur\u010dit\u00e1 zdravotn\u00ed rizika \u2013 pokud m\u00e1te v rodin\u011b p\u0159\u00edpady zneu\u017e\u00edv\u00e1n\u00ed alkoholu, onemocn\u011bn\u00ed jater nebo ur\u010dit\u00fdch druh\u016f rakoviny, m\u011bli byste b\u00fdt opatrn\u00ed p\u0159i konzumaci jak\u00fdchkoli alkoholick\u00fdch n\u00e1poj\u016f. Neexistuj\u00ed \u017e\u00e1dn\u00e9 p\u00e1dn\u00e9 d\u016fvody, pro\u010d za\u010d\u00edt p\u00edt \u010derven\u00e9 v\u00edno. Pokud v\u0161ak ji\u017e \u010derven\u00e9 v\u00edno pijete, je nepravd\u011bpodobn\u00e9, \u017ee by v\u00e1m ob\u010dasn\u00e1 sklenka n\u011bjak v\u00fdrazn\u011b u\u0161kodila.<\/p>\n\n
