Forever chemicals<\/em> \u0219i efectele lor asupra corpului<\/h2>\n

Ridurile \u0219i liniile de expresie ne arat\u0103 v\u00e2rsta pe exterior, dar anumite substan\u021be sintetice din cas\u0103 afecteaz\u0103 \u021besuturile interne \u0219i accelereaz\u0103 \u00eemb\u0103tr\u00e2nirea biologic\u0103. Cercet\u0103rile indic\u0103 c\u0103 b\u0103rba\u021bii de v\u00e2rst\u0103 mijlocie sunt cel mai vulnerabili, scrie NYPost<\/a>.<\/p>\n

Un studiu din Shanghai a analizat substan\u021bele per- \u0219i polifluoroalchilice, cunoscute drept PFAS sau \u201eforever chemicals\u201d. Cercet\u0103torii s-au concentrat pe dou\u0103 chimicale, PFNA \u0219i PFOSA, \u0219i au identificat markeri de \u00eemb\u0103tr\u00e2nire biologic\u0103 \u0219i dezechilibre \u00een metabolismul lipidic.<\/strong><\/p>\n

Expunerea la aceste chimicale inhib\u0103 capacitatea organismului de a regla inflama\u021bia, de a repara ADN-ul \u0219i de a metaboliza proteinele. S-a constatat \u0219i o senescen\u021b\u0103 celular\u0103 mai mare, adic\u0103 oprirea diviziunii celulare. Alte studii au ar\u0103tat c\u0103 inflama\u021bia cauzat\u0103 de PFAS poate duce la leziuni tisulare, disfunc\u021bii musculare, probleme mitocondriale \u0219i declin metabolic sistemic.<\/p>\n

Studiul american \u0219i diferen\u021bele de gen<\/h2>\n

Cercet\u0103torii au analizat probele de s\u00e2nge a 326 de persoane \u00een cadrul US National Health and Nutrition Examination Survey (1999\u20132000). PFNA \u0219i PFOSA erau prezente la aproape 95% dintre participan\u021bi. Nivelurile ridicate de PFNA la b\u0103rba\u021bii \u00eentre 50 \u0219i 64 de ani au fost asociate cu o \u00eemb\u0103tr\u00e2nire epigenetic\u0103 mai rapid\u0103 dec\u00e2t la femeile de aceea\u0219i v\u00e2rst\u0103<\/strong>, f\u0103r\u0103 o explica\u021bie clar\u0103. Posibile cauze includ stilul de via\u021b\u0103, dar diferen\u021ba de gen nu este complet explicat\u0103.<\/p>\n

PFAS au fost dezvoltate \u00een anii 1940 \u0219i introduse pentru consumatori \u00een anii 1950, datorit\u0103 propriet\u0103\u021bilor rezistente la ap\u0103, gr\u0103simi \u0219i c\u0103ldur\u0103<\/strong>. Le reg\u0103sim ast\u0103zi \u00een pelerinele de ploaie, tig\u0103ile antiaderente, tapi\u021berie \u0219i ambalaje alimentare. Ele nu se descompun u\u0219or, carbonul-fluor din structura lor put\u00e2nd persista peste 1000 de ani.<\/strong><\/p>\n

Expunerea la PFAS este asociat\u0103 cu cre\u0219terea colesterolului, eficien\u021b\u0103 redus\u0103 a vaccinurilor, afec\u021biuni hepatice, hipertensiune indus\u0103 de sarcin\u0103, preeclampsie, greutate mic\u0103 la na\u0219tere \u0219i risc crescut de cancer renal sau testicular<\/strong>. Chiar \u0219i alternativele mai noi PFNA \u0219i PFOSA nu par s\u0103 fie sigure pentru anumite grupuri de popula\u021bie.<\/p>\n

P\u00e2n\u0103 la reglement\u0103ri mai stricte, speciali\u0219tii recomand\u0103 s\u0103 limit\u0103m consumul de alimente ambalate \u0219i s\u0103 evit\u0103m \u00eenc\u0103lzirea \u00een cuptorul cu microunde a recipientelor de tip fast-food. Prezen\u021ba \u201eforever chemicals\u201d \u00een ap\u0103, ploaie \u0219i s\u00e2nge poate face organismul mai vulnerabil la boli \u00een anii care preced b\u0103tr\u00e2ne\u021bea, c\u00e2nd apar schimb\u0103ri biologice \u0219i vulnerabilit\u0103\u021bi crescute, cum ar fi boli cardiovasculare, tulbur\u0103ri metabolice \u0219i degenerare tisular\u0103 timpurie.<\/p>\n","protected":false},"excerpt":{"rendered":"
