Autorii subliniaz\u0103 \u00eens\u0103 c\u0103 rezultatele ob\u021binute pe animale nu trebuie interpretate automat ca efecte ale dietei vegane asupra oamenilor, potrivit Newsweek<\/a>.<\/p>\n

Schimb\u0103ri observate dup\u0103 numai dou\u0103 zile<\/h2>\n

Cercet\u0103torii au urm\u0103rit efectele trecerii de la o alimenta\u021bie care con\u021binea at\u00e2t proteine vegetale, c\u00e2t \u0219i animale la una bazat\u0103 exclusiv pe surse vegetale.<\/p>\n

Pentru experiment au fost comparate dou\u0103 grupuri de \u0219oareci: unul a primit o diet\u0103 lactovegetarian\u0103, care includea proteine animale \u0219i vegetale, iar cel\u0103lalt o diet\u0103 vegan\u0103.<\/p>\n

Pierre Maechler, profesor de fiziologie celular\u0103 \u0219i metabolism la Facultatea de Medicin\u0103 a Universit\u0103\u021bii din Geneva \u0219i unul dintre autorii cercet\u0103rii, a explicat c\u0103 dup\u0103 numai dou\u0103 zile \u0219oarecii hr\u0103ni\u021bi exclusiv cu proteine vegetale prezentau o capacitate mai redus\u0103 de producere a glucozei.<\/p>\n

Mai exact, ficatul animalelor era mai pu\u021bin eficient \u00een men\u021binerea glicemiei \u00een perioadele de post, proces la care contribuie \u00een mod normal aminoacizii.<\/p>\n

\u00cen paralel, cercet\u0103torii au observat o reducere semnificativ\u0103 a activit\u0103\u021bii fizice spontane. \u0218oarecii, care \u00een mod normal alergau de bun\u0103voie pe dispozitivele amplasate \u00een spa\u021biul lor, au devenit mult mai pu\u021bin activi.<\/p>\n

Efectul a fost reversibil<\/h2>\n

Potrivit cercet\u0103torilor, modificarea comportamentului a fost rapid reversibil\u0103 dup\u0103 reintroducerea proteinelor animale \u00een alimenta\u021bie.<\/p>\n

Este important \u00eens\u0103 c\u0103 dieta respectiv\u0103 nu con\u021binea carne. Sursa de protein\u0103 animal\u0103 folosit\u0103 \u00een experiment era cazeina, o protein\u0103 din lapte asociat\u0103 proces\u0103rii produselor lactate.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 au identificat \u0219i modific\u0103ri ale mecanismului prin care organismul gestioneaz\u0103 amoniacul. \u00cen cazul \u0219oarecilor hr\u0103ni\u021bi exclusiv cu proteine vegetale a sc\u0103zut produc\u021bia enzimei glutamat-dehidrogenaz\u0103 (GDH), implicat\u0103 \u00een leg\u0103tura dintre metabolismul proteinelor \u0219i cel al glucidelor.<\/p>\n

Reducerea activit\u0103\u021bii acestei enzime a fost asociat\u0103 cu acumularea de amoniac \u00een organismul animalelor.<\/p>\n

Autorul studiului atrage aten\u021bia asupra proteinelor<\/h2>\n

Maechler sus\u021bine c\u0103 o alimenta\u021bie vegan\u0103 este posibil\u0103, dar necesit\u0103 aten\u021bie pentru asigurarea necesarului de proteine, fier \u0219i calciu, precum \u0219i suplimentarea vitaminei B12.<\/p>\n

Cercet\u0103torul consider\u0103 c\u0103 trebuie avut\u0103 \u00een vedere \u0219i calitatea proteinelor consumate, inclusiv aportul de aminoacizi cu caten\u0103 ramificat\u0103 (BCAA), precum leucina, izoleucina \u0219i valina. Printre sursele vegetale indicate de acesta se num\u0103r\u0103 tofu, nucile \u0219i lintea.<\/p>\n

Rezultatele pe \u0219oareci nu pot fi transferate direct la oameni<\/h2>\n

Al\u021bi speciali\u0219ti avertizeaz\u0103 \u00eens\u0103 c\u0103 experimentul nu demonstreaz\u0103 c\u0103 o diet\u0103 vegan\u0103 produce acelea\u0219i efecte asupra oamenilor.<\/p>\n

Dr. Neal Barnard, profesor de medicin\u0103 la George Washington University School of Medicine, a atras aten\u021bia c\u0103 enzima GDH studiat\u0103 prezint\u0103 diferen\u021be importante \u00eentre specii \u0219i c\u0103 metabolismul \u0219oarecilor nu este identic cu cel uman.<\/p>\n

El a invocat cercet\u0103ri efectuate pe oameni care au asociat alimenta\u021bia vegetal\u0103 cu un control mai bun al glicemiei \u0219i cu \u00eembun\u0103t\u0103\u021birea unor indicatori ai s\u0103n\u0103t\u0103\u021bii ficatului.<\/p>\n

Prin urmare, studiul nu poate fi interpretat ca o demonstra\u021bie c\u0103 dieta vegan\u0103 provoac\u0103 probleme hepatice la oameni.<\/p>\n

Autorii consider\u0103 c\u0103 urm\u0103torul pas important este realizarea unor cercet\u0103ri similare pe subiec\u021bi umani, \u00een special pentru a analiza ce se \u00eent\u00e2mpl\u0103 imediat dup\u0103 schimbarea surselor de proteine din alimenta\u021bie.<\/p>\n","protected":false},"excerpt":{"rendered":"
