Ce este siliciul?<\/h2>\n

Siliciul este un element prezent \u00een urme mici \u00een organism. Este un ingredient esen\u021bial pentru \u00eent\u0103rirea \u021besuturilor conjunctive, a oaselor \u0219i a articula\u021biilor, precum \u0219i pentru \u00eengrijirea unghiilor, a p\u0103rului \u0219i a pielii. Corpul uman con\u021bine 7 grame de siliciu, prezente \u00een diferite \u021besuturi \u0219i fluide ale corpului. Beneficiile siliciului asupra s\u0103n\u0103t\u0103\u021bii joac\u0103 un rol important \u00een prevenirea anumitor afec\u021biuni, cum ar fi ateroscleroza, tuberculoza, tulbur\u0103rile de somn \u0219i probleme ale pielii.<\/p>\n

 <\/p>\n

Care este func\u021bia siliciului?<\/h2>\n

Siliciul este necesar pentru sinteza colagenului \u0219i a elastinei \u0219i este important pentru s\u0103n\u0103tatea \u021besuturilor conjunctive, a oaselor, cartilajelor, tendoanelor \u0219i articula\u021biilor. Colagenul ac\u021bioneaz\u0103 ca o schel\u0103, care ofer\u0103 suport \u021besuturilor, \u00een timp ce elastina ofer\u0103 elasticitate \u021besuturilor, pielii, p\u0103rului \u0219i vaselor de s\u00e2nge.<\/p>\n

Oasele sunt de fapt un tip special de \u021besut conjunctiv. Pe m\u0103sur\u0103 ce osul se maturizeaz\u0103, concentra\u021bia de siliciu scade, \u0219i \u00een acela\u0219i timp se formeaz\u0103 depozite de calciu \u0219i fosfor. Prin urmare, s-a concluzionat c\u0103 siliciul ac\u021bioneaz\u0103 ca factor de reglare a depunerii de calciu \u0219i fosfor \u00een \u021besutul osos. \u00cen plus fa\u021b\u0103 de \u021besutul conjunctiv \u0219i s\u0103n\u0103tatea osoas\u0103, siliciul joac\u0103 un rol \u0219i \u00een alte beneficii pentru s\u0103n\u0103tate, cum ar fi protec\u021bia \u00eempotriva toxicit\u0103\u021bii aluminiului \u0219i protec\u021bia \u021besutului arterial.<\/p>\n

 <\/p>\n

Ce alimente sunt bogate \u00een siliciu?<\/h2>\n

Siliciul este prezent \u00een ov\u0103z, sfecl\u0103, orz, boabe de soia, semin\u021be, precum \u0219i r\u0103d\u0103cinoase \u0219i plante ierboase, cum ar fi Limba mielului \u0219i urzicile. Includerea \u00een dieta zilnic\u0103 a siliciului poate cre\u0219te beneficiile calciului, glucozominei \u0219i vitaminei D.<\/p>\n

 <\/p>\n

Care este cerin\u021ba zilnic\u0103 recomandat\u0103 de siliciu?<\/h2>\n

Aportul zilnic de siliciu recomandat este cuprins \u00eentre 20-50 mg. Plantele absorb acidul ortosilicic din sol \u0219i \u00eel transform\u0103 \u00een siliciu polimerizat pentru suport mecanic \u0219i structural. De aceea, alimentele cum sunt cerealele, ov\u0103zul \u0219i legumele au o concentra\u021bie mare de siliciu, \u0219i o cantitate limitat\u0103 de legume, cereale \u0219i fructe ofer\u0103 o concentra\u021bie sc\u0103zut\u0103 de siliciu.<\/p>\n

 <\/p>\n

Care sunt consecin\u021bele deficien\u021bei de siliciu?<\/h2>\n

Deficitul de siliciu poate deshidrata unghiile, f\u0103c\u00e2ndu-le fragile, \u0219i poate afecta s\u0103n\u0103tatea pielii \u0219i a p\u0103rului. De asemenea, aciditatea mai sc\u0103zut\u0103 a stomacului (datorat\u0103 bolii sau \u00eemb\u0103tr\u00e2nirii) diminueaz\u0103 capacitatea de a metaboliza siliciul din surse alimentare, ceea ce duce la o diet\u0103 cu con\u021binut sc\u0103zut de siliciu. Femeile \u00eens\u0103rcinate sau care al\u0103pteaz\u0103 nu trebuie s\u0103 ia suplimente de siliciu, deoarece pot d\u0103una mamei \u0219i copilului.<\/p>\n

 <\/p>\n

Care sunt consecin\u021bele aportului excesiv de siliciu?<\/h2>\n

Un consum prelungit \u0219i \u00een exces de siliciu este asociat cu silicoza, o boal\u0103 pulmonar\u0103. De asemenea, s-a constatat c\u0103 nivelurile crescute de siliciu \u0219i aluminiu au fost g\u0103site \u00een creierul persoanelor cu Alzheimer. \u00cen plus,<\/p>\n

utilizarea prelungit\u0103 a substan\u021belor cu concentrat ridicat de siliciu a fost asociat\u0103 \u0219i cu formarea de pietre la rinichi la unele persoane.<\/p>\n

 <\/p>\n

Este adev\u0103rat c\u0103 suplimentele de siliciu ofer\u0103 beneficii s\u0103n\u0103t\u0103\u021bii p\u0103rului?<\/h2>\n

Cel mai bun mod de a primi o cantitate esen\u021bial\u0103 de siliciu este de a m\u00e2nca alimente bogate \u00een acest mineral. Din p\u0103cate, cel mai adesea siliciul nu este absorbit bine \u0219i, \u00een unele cazuri, poate fi necesar\u0103 administrarea de suplimente. \u00cen orice caz, solicitarea unui consult medical este crucial\u0103 pentru a preveni orice complica\u021bii nedorite.<\/p>\n","protected":false},"featured_media":0,"parent":0,"template":"","Example":[1779],"class_list":["post-80639","enciclopedia","type-enciclopedia","status-publish","hentry","enciclopedia_category-minerale"],"yoast_head":"\nSiliciul - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"ro_RO\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Siliciul - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Ce este siliciul?
