Gena gustului poate explica de ce anumite alimente \u00ee\u021bi par insuportabile, de\u0219i al\u021bii le consum\u0103 f\u0103r\u0103 nicio problem\u0103, potrivit Futura Sciences<\/a>.<\/p>\n

Cercet\u0103rile recente arat\u0103 c\u0103 varia\u021biile genetice modific\u0103 percep\u021bia aromelor, \u00een special a gustului amar. Diferen\u021bele biologice dintre indivizi sunt, adesea, mai puternice dec\u00e2t obi\u0219nuin\u021ba sau educa\u021bia alimentar\u0103.<\/p>\n

Pe limb\u0103 \u0219i \u00een cavitatea bucal\u0103, celule specializate detecteaz\u0103 moleculele din alimente. Ele transmit informa\u021bia c\u0103tre creier, care interpreteaz\u0103 senza\u021bia gustativ\u0103. Acest proces pare simplu, dar varia\u021biile genetice \u00eel pot schimba complet.<\/p>\n

Cercet\u0103torii au identificat o gen\u0103 cu un rol central \u00een aceast\u0103 poveste: TAS2R38.<\/strong> Ea codific\u0103 un receptor implicat direct \u00een percep\u021bia gustului amar. \u00cen func\u021bie de versiunea mo\u0219tenit\u0103, acela\u0219i compus amar poate p\u0103rea intens sau aproape inexistent.<\/p>\n

\u201eSuper-tasters\u201d \u0219i \u201enon-tasters\u201d: dou\u0103 lumi diferite<\/h2>\n

Oamenii de \u0219tiin\u021b\u0103 \u00eempart popula\u021bia \u00een mai multe profiluri de percep\u021bie gustativ\u0103. \u201eSuper-tasters\u201d sunt persoanele cu o sensibilitate ridicat\u0103 la arome, mai ales la amar. \u201eNon-tasters\u201d detecteaz\u0103 aceia\u0219i compu\u0219i mult mai slab.<\/p>\n

Aceast\u0103 diferen\u021b\u0103 nu este o chestiune de caracter sau educa\u021bie. Este \u00eenscris\u0103 \u00een ADN.<\/p>\n

Persoanele din categoria \u201esuper-tasters\u201d evit\u0103 frecvent alimentele bogate \u00een compu\u0219i amari. Varza de Bruxelles, cafeaua neagr\u0103 sau anumite b\u0103uturi vegetale le pot p\u0103rea efectiv nepl\u0103cute. Nu este un moft \u2013 este biologie.<\/p>\n

Am\u0103r\u0103ciunea, un semnal de ap\u0103rare vechi de mii de ani<\/h2>\n

Sensibilitatea la amar nu a ap\u0103rut \u00eent\u00e2mpl\u0103tor. Multe substan\u021be toxice din natur\u0103 au gust amar. Receptorii gustativi au func\u021bionat, de-a lungul evolu\u021biei umane, ca un sistem de alert\u0103.<\/p>\n

O sensibilitate crescut\u0103 la amar ar fi putut proteja str\u0103mo\u0219ii no\u0219tri de plante sau substan\u021be periculoase. Ast\u0103zi, acela\u0219i mecanism \u00eei face pe unii oameni s\u0103 resping\u0103 alimente perfect s\u0103n\u0103toase.<\/p>\n

Genetica explic\u0103 mult, dar nu totul<\/h2>\n

Gena gustului nu este singurul factor care determin\u0103 preferin\u021bele alimentare. Expunerea repetat\u0103 la un aliment poate modifica treptat percep\u021bia. Experien\u021bele din copil\u0103rie, cultura alimentar\u0103 \u0219i v\u00e2rsta joac\u0103 \u0219i ele un rol.<\/p>\n

Starea de s\u0103n\u0103tate \u0219i anumite obiceiuri pot influen\u021ba chiar func\u021bionarea receptorilor gustativi. Percep\u021bia gustului este, \u00een final, rezultatul unui dialog permanent \u00eentre biologie \u0219i mediu.<\/p>\n

Varia\u021biile genetice stabilesc sensibilitatea de baz\u0103. Experien\u021ba alimentar\u0103 o modeleaz\u0103 \u00een timp.<\/p>\n","protected":false},"excerpt":{"rendered":"
