Segurament en m\u00e9s d\u2019una ocasi\u00f3, heu sentit a parlar sobre el poder dels antioxidants, per\u00f2 molts cops no sabem explicar realment qu\u00e8 s\u00f3n. Per aix\u00f2, hem cregut interessant, ara que s\u2019apropa el bon temps, parlant dels beneficis d\u2019aquestes subst\u00e0ncies.<\/p>\n

Els antioxidants<\/strong> s\u00f3n un grup de vitamines, minerals i enzims, presents tant en la dieta com en l\u2019organisme, que ens protegeixen contra l\u2019exc\u00e9s de radicals lliures, components causants de l\u2019envelliment i d\u2019algunes malalties, sobretot les degeneratives i les relacionades amb el sistema immunol\u00f2gic i cardiovascular.<\/p>\n

Tipus d\u2019antioxidants, funcions i aliments que els contenen:<\/h3>\n

 <\/p>\n

VITAMINES<\/strong><\/span><\/h4>\n

VITAMINA A.<\/strong> Tamb\u00e9 anomenada retinol, ja que genera pigments necessaris per al funcionament de la retina, realitza una tasca important en el desenvolupament d\u2019una bona visi\u00f3 especialment la nocturna. Tamb\u00e9 \u00e9s fonamental per a les c\u00e8l\u00b7lules de la pell, ossos i mucoses. A m\u00e9s, protegeix del dany dels radicals lliures, prevenint l\u2019envelliment prematur.<\/p>\n

FUENTE: Present sobretot en aliments de color taronja: pastanaga, rovell de l\u2019ou, fruites de color taronja i groc, cereals d\u2019esmorzar fortificats, peix (sardines, tonyina, fetge de qualsevol peix) i verdures com el julivert i els espinacs.<\/p>\n

VITAMINA E.<\/strong> El tocoferol o vitamina E \u00e9s important en la formaci\u00f3 de gl\u00f2buls vermells en l\u2019organisme. Aix\u00ed mateix, col\u00b7labora en un grau significatiu en la formaci\u00f3 de m\u00fasculs i teixits del cos. Tamb\u00e9 destaca pel seu poder antioxidant, reduint les afeccions relacionades en l\u2019envelliment.<\/p>\n

FUENTE: Olis d\u2019origen vegetal (oliva, blat de moro i gira-sol), fruits secs (nous, ametlles, pipes, etc.), llavors i cereals (blat<\/a>, arr\u00f2s<\/a>, etc.).<\/p>\n

VITAMINA C.<\/strong> La vitamina C contribueix a la reparaci\u00f3 i manteniment dels ossos, dents i cart\u00edlags. A m\u00e9s, \u00e9s imprescindible per a l\u2019absorci\u00f3 del ferro i t\u00e9 un paper important en la s\u00edntesi del col\u00b7lagen i en la cicatritzaci\u00f3 de les ferides.<\/p>\n

FUENTE: Fruites i verdures, sobretot de color verd i vermell (pebrot, cogombre, julivert, tom\u00e0quet, c\u00edtrics, mel\u00f3, kiwi, etc.).<\/p>\n

OLIGOELEMENTS <\/strong><\/span><\/h4>\n

SELENI.<\/strong>\u00a0Oligoelement essencial, \u00e9s a dir, el nostre cos no t\u00e9 la capacitat de produir-ho, sent imprescindible que ho prenguem a trav\u00e9s de la dieta per evitar manques. T\u00e9 com a unci\u00f3 produir enzims antioxidants, un tipus de prote\u00efnes especials que juguen un paper crucial en la prevenci\u00f3 del dany cel\u00b7lular.<\/p>\n

FUENTE: Ous, bolets, cereals, marisc, pipes de gira-sol, all…<\/p>\n

ZINC.<\/strong>\u00a0Participa en la divisi\u00f3 i el creixement de les c\u00e8l\u00b7lules, igual que en la cicatritzaci\u00f3 de ferides i en el metabolisme dels hidrats de carboni. A m\u00e9s, \u00e9s imprescindible perqu\u00e8 el sistema immunitari funcioni de forma adequada.<\/p>\n

FUENTE: Cereals, ostres i fruits secs.<\/p>\n

POLIFENOLS<\/strong><\/span><\/h4>\n

Els polifenols<\/strong> s\u00f3n composts d\u2019origen vegetal amb capacitat antioxidant especialment interessats des del punt de vista nutricional pel paper que exerceixen en la prevenci\u00f3 de les alteracions funcionals i estructurals de diverses malalties.<\/p>\n

FUENTE: Fruites vermelles, c\u00edtrics, oli d\u2019oliva, ra\u00efm i derivats, llegums.<\/p>\n

En definitiva…<\/strong><\/h3>\n

Encara que ja hem vist que s\u00f3n molts els aliments rics en antioxidants, el m\u00e9s important per evitar manques \u00e9s dur a terme una dieta equilibrada, suficient i, sobretot, variada. Aquesta hauria d\u2019incloure de forma di\u00e0ria cinc racions de fruites, verdures i hortalisses, intentant en la mesura del possible, que siguin fresques i de temporada. A m\u00e9s, evitar tots aquells h\u00e0bits nocius que incrementen el nivell d\u2019oxidaci\u00f3 del nostre organisme com pot ser l\u2019estr\u00e8s, el consum de tabac, la contaminaci\u00f3 ambiental i un exc\u00e9s d\u2019exposici\u00f3 solar.<\/p>\n","protected":false},"excerpt":{"rendered":"
