\nCercet\u0103torii de la King\u2019s College London au identificat o posibil\u0103 leg\u0103tur\u0103 \u00eentre teobromin\u0103, un compus natural prezent \u00een ciocolata neagr\u0103, \u015fi o \u00eemb\u0103tr\u00e2nire biologic\u0103 mai lent\u0103, pe baza unor date moleculare provenite de la peste 1.600 de participan\u0163i, scrie SciTechDaily.<\/p>\n
\nStudiul a analizat nivelurile de teobromin\u0103 din s\u00e2nge \u015fi a constatat c\u0103 persoanele cu concentra\u0163ii mai ridicate prezentau o v\u00e2rst\u0103 biologic\u0103 mai mic\u0103 dec\u00e2t v\u00e2rsta lor cronologic\u0103, pe baza analizei modific\u0103rilor chimice ale ADN-ului. Oamenii de \u015ftiin\u0163\u0103 au evaluat date din cohortele TwinsUK \u015fi KORA, demonstr\u00e2nd c\u0103 teobromina poate influen\u0163a markerii de \u00eemb\u0103tr\u00e2nire care regleaz\u0103 activitatea genelor \u00een timp.<\/p>\n
\nV\u00e2rsta biologic\u0103 a fost estimat\u0103 folosind \u201eceasuri\u201d epigenetice care urm\u0103resc modific\u0103rile chimice din ADN, \u00eempreun\u0103 cu lungimea telomerilor, care se scurteaz\u0103 odat\u0103 cu v\u00e2rsta \u015fi se coreleaz\u0103 cu deteriorarea integrit\u0103\u0163ii celulare. Teobromina s-a eviden\u0163iat dintre mai mul\u0163i compu\u015fi din cacao \u015fi cafea testa\u0163i, prezent\u00e2nd cea mai puternic\u0103 asociere cu indicatori de \u00eemb\u0103tr\u00e2nire \u00eembun\u0103t\u0103\u0163i\u0163i \u00een r\u00e2ndul popula\u0163iilor analizate.<\/p>\n
\nExper\u0163ii consider\u0103 c\u0103 alcaloizii deriva\u0163i din plante, precum teobromina, pot modula sistemele de expresie genetic\u0103, oferind indicii despre modul \u00een care alimentele obi\u015fnuite influen\u0163eaz\u0103 s\u0103n\u0103tatea pe termen lung. Cercet\u0103torii subliniaz\u0103 c\u0103 aceste rezultate nu sugereaz\u0103 c\u0103 un consum mai mare de ciocolat\u0103 neagr\u0103 va \u00eencetini \u00eemb\u0103tr\u00e2nirea, av\u00e2nd \u00een vedere con\u0163inutul de zah\u0103r \u015fi gr\u0103simi.<\/p>\n
\nStudii viitoare vor analiza modul \u00een care teobromina interac\u0163ioneaz\u0103 cu al\u0163i compu\u015fi din cacao, precum polifenolii, \u015fi dac\u0103 efectele combinate contribuie la semn\u0103turile biologice observate.<\/p>\n","protected":false},"excerpt":{"rendered":"
