\u010cerven\u00e9 hrozny pos\u00edl\u00ed zdrav\u00ed a vedou pr\u00fd i k dlouhov\u011bkosti. V jejich slupce je toti\u017e l\u00e1tka, je\u017e podle americk\u00fdch v\u011bdc\u016f zpomaluje st\u00e1rnut\u00ed. Podle nich by se \u010dlov\u011bk d\u00edky n\u00ed mohl do\u017e\u00edt a\u017e 150 let. Informoval o tom list Daily Telegraph.<\/p>\n
„Vypad\u00e1 to slibn\u011b. Zji\u0161\u0165ujeme, \u017ee st\u00e1rnut\u00ed nen\u00ed nezpomaliteln\u00fd proces, jak jsme si mysleli. N\u011bkte\u0159\u00ed z n\u00e1s by mohli \u017e\u00edt do 150 let, ale k tomu se nedostaneme bez dal\u0161\u00edho v\u00fdzkumu,“ prohla\u0161uje podle listu profesor David Sinclair z Harvardovy univerzity.<\/p>\n
Genetik Sinclair zkoumal \u00fa\u010dinky resveratrolu na v\u010del\u00e1ch, my\u0161\u00edch a mu\u0161k\u00e1ch. L\u00e1tka podle jeho zji\u0161t\u011bn\u00ed povzbuzuje aktivitu b\u00edlkoviny zvan\u00e9 SIRT1. Ta zlep\u0161uje \u010dinnost bun\u011bk v t\u011ble. Testy uk\u00e1zaly, \u017ee jedinci, kte\u0159\u00ed dost\u00e1vali resveratrol, \u017eili d\u00e9le.<\/p>\n
Ve studii, kterou zve\u0159ejnil odborn\u00fd \u010dasopis Science, Sinclair uv\u00e1d\u00ed, \u017ee l\u00e1tka m\u011bla p\u0159\u00edm\u00fd \u00fa\u010dinek na zlep\u0161en\u00ed zdrav\u00ed v p\u0159\u00edpadech od cukrovky p\u0159es rakovinu a\u017e k Alzheimerov\u011b chorob\u011b \u010di lup\u00e9nce.<\/p>\n
Kritici sice tvrd\u00ed, \u017ee tento \u00fa\u010dinek nen\u00ed re\u00e1ln\u00fd, to ale neodradilo farmaceutickou firmu GSK, kter\u00e1 se rozhodla zkou\u0161et resveratrol na lidech. Pacienti s cukrovkou druh\u00e9ho typu ani lid\u00e9 posti\u017een\u00ed lup\u00e9nkou, kte\u0159\u00ed se na testech pod\u00edlej\u00ed, p\u0159itom nemusej\u00ed konzumovat kvanta hrozn\u016f.<\/p>\n

Ovoce m\u00e1 sice obecn\u011b prosp\u011b\u0161n\u00e9 \u00fa\u010dinky na zdrav\u00ed, hrozny nevyj\u00edmaje, ale \u00fa\u010dinky resveratrolu na dlohov\u011bkost jsou mnoh\u00fdmi v\u011bdci zpochyb\u0148ovan\u00e9. <\/p>\n
Kritici poukazuj\u00ed na p\u0159\u00edpad, jen\u017e se ned\u00e1vno stal v univerzit\u011b v americk\u00e9m Connecticutu, kde byl jeden ze jej\u00edch pedagog\u016f, profesor indick\u00e9ho p\u016fvodu Dipak K. Das, obvin\u011bn z v\u011bdeck\u00fdch podvod\u016f. Publikoval toti\u017e \u0159adu \u010dl\u00e1nk\u016f v v\u011bdeck\u00fdch \u010dasopisech, ve kter\u00fdch se sna\u017eil prokazovat prosp\u011b\u0161nost \u010derven\u00e9ho v\u00edna, respektive v n\u011bm obsa\u017een\u00e9ho resveratrolu. Jeho \u00fa\u010dinky potvrzoval prof. Das na zv\u00ed\u0159atech, jim\u017e m\u011bl resveratrol prodlu\u017eovat \u017eivot. V\u00fdsledky v\u0161ak byly fal\u0161ov\u00e1ny.<\/p>\n
Das dost\u00e1val na nov\u00e9 a nov\u00e9 studie o resveratrolu granty a m\u011bli ho r\u00e1di i v\u00fdrobci \u010derven\u00e9ho v\u00edna, jim\u017e sv\u00fdmi \u010dl\u00e1nky zvy\u0161oval tr\u017eby. <\/p>\n
Pokusy u ni\u017e\u0161\u00edch organism\u016f nap\u0159. ban\u00e1nov\u00fdch mu\u0161ek, \u010derv\u016f atd. sice skute\u010dn\u011b prok\u00e1zaly, \u017ee resveratrol u nich v\u00fdznamn\u011b prodlu\u017euje v\u011bk, ale to je\u0161t\u011b neznamen\u00e1, \u017ee tak bude p\u016fsobit i u lid\u00ed nebo jin\u00fdch vy\u0161\u0161\u00edch organism\u016f. Tento \u00fa\u010dinek zat\u00edm u lid\u00ed nebyl prok\u00e1z\u00e1n v\u011brohodnou studi\u00ed.
