\"Carne<\/a>Dietele bogate \u00een proteine, cum este \u0219i celebra Dukan, cresc \u0219ansele de a dezvolta pietre la rinichi \u0219i alte boli renale, spun cercet\u0103torii de la Universitatea Granada, Spania. \u00cen urma experimentului f\u0103cut recent pe 20 de \u0219oareci, ace\u0219tia au ar\u0103tat c\u0103 dietele bogate in proteine cresc, pe termen lung, riscul de a dezvolta o boala de rinichi \u0219i pot avea un efect negativ asupra markerilor urinari.<\/p>\n

Ba mai mult, aceste diete<\/strong> pot duce la patologii grave, cum ar fi litiaza renal\u0103<\/strong> (pietre la rinichi ), deoarece<\/strong> reduc drastic citratul urinar<\/strong> (un inhibitor major al form\u0103rii calculilor renali), pH-ul\u00a0urinar \u0219i cresc calciul urinar<\/strong> (pentru a compensa aciditatea metabolic\u0103 cauzat\u0103 de excesul de proteine\u200b\u200b) .<\/p>\n

Cercetatorii au \u00eemp\u0103r\u021bit \u0219oarecii \u00een dou\u0103 grupe de c\u00e2te 10. Primul grup a fost hranit cu o dieta bogata in proteine (un nivel de proteine \u200b\u200bde 45 %). Cel de-al doilea grup a avut un regim normal de proteine. Experimentul s-a \u00eentins pe durata a 12 s\u0103pt\u0103m\u00e2ni, ceea ce echivaleaz\u0103, spun cercet\u0103torii, cu 9 ani din via\u021ba unui om.<\/strong><\/p>\n

\"Fructe<\/a>Pierderea \u00een greutate a fost de 10%<\/strong><\/p>\n

Rezultatele experimentului au ar\u0103tat c\u0103 \u0219oarecii care au beneficiat de un regim bogat \u00een proteine, \u200b\u200bau pierdut p\u00e2n\u0103 la 10 % din greutatea corpului lor, dar n-au cunoscut nici o \u00eembun\u0103t\u0103\u021bire a profilului lipidic plasmatic (profilul lipidic indic\u0103 posibile anomalii \u00een lipide, cum ar fi colesterolul \u0219i trigliceridele – instrument pentru determinarea riscului de boal\u0103 coronarian\u0103)<\/strong>. Mai mult dec\u00e2t at\u00e2t, citratul urinar la ace\u0219ti \u0219oareci a fost cu 88% mai mic, iar pH-ul urinar a fost cu 15 % mai acid.<\/p>\n

La acelea\u0219i animale beneficiare ale unui regim hiperproteic, greutatea rinichiului a crescut cu 22 %,<\/strong> glomerulul<\/strong> (re\u021beaua de capilare care elaboreaz\u0103 urina primar\u0103 prin filtrarea s\u00e2ngelui) – cu 13%<\/strong> \u0219i mezangiumul<\/strong> (o structura de colagen \u00eenconjurat\u0103 de aceste capilare) – cu 32%<\/strong> .<\/p>\n

Rezultatele acestui experiment o determin\u0103 pe dr. Virginia A. Aparicio de la Universitatea din \"Broccoli\"<\/a>Granada, Catedra de Fiziologie, s\u0103 sublinieze necesitatea de a monitoriza \u00eendeaproape pe oricine are o dieta bogat\u0103 in proteine\u200b\u200b.<\/p>\n

Dr. Aparicio mai spune c\u0103 efectele negative ale dietelor bogate in proteine \u200b\u200basupra rinichilor depind \u0219i de prezen\u021ba altor elemente nutritive din alimenta\u021bie: ” Consumul crescut de fructe \u0219i legume reduce riscul form\u0103rii pietrelor la rinichi, datorit\u0103 con\u021binutului bogat \u00een potasiu \u0219i magneziu, care compenseaz\u0103 aciditatea din dietele\u00a0 bogate \u00een proteine.”
