Vitamin B12, sa\u011fl\u0131kl\u0131 kan h\u00fccrelerinin \u00fcretiminden sinir sistemi fonksiyonlar\u0131n\u0131n korunmas\u0131na, zihinsel odaklanman\u0131n desteklenmesinden enerji metabolizmas\u0131na kadar bir\u00e7ok \u00f6nemli g\u00f6revi yerine getiriyor. Bilim insanlar\u0131 \u015fimdi ise B12 vitamininin yeni bir faydas\u0131n\u0131 daha ortaya koydu.<\/p>\n\n\n\n

Fareler \u00fczerinde yap\u0131lan son ara\u015ft\u0131rmada, B12 eksikli\u011finin metabolizma \u00fczerinde strese yol a\u00e7abilece\u011fi ve ba\u011f\u0131\u015f\u0131kl\u0131k sistemini tehdit eden etkenlerle m\u00fccadeleyi zorla\u015ft\u0131rabilece\u011fi belirlendi.<\/p>\n\n\n\n
Ara\u015ft\u0131rmac\u0131lar, bulgular\u0131n yeterli B12 alamayan milyonlarca ki\u015fi a\u00e7\u0131s\u0131ndan \u00f6nem ta\u015f\u0131d\u0131\u011f\u0131na dikkat \u00e7ekiyor. Uzmanlar, et \u00fcr\u00fcnleri ile B12 takviyeli tah\u0131l ve ekmek gibi g\u0131dalar\u0131 i\u00e7eren dengeli bir beslenme program\u0131n\u0131n vitamin ihtiyac\u0131n\u0131 kar\u015f\u0131lamaya yard\u0131mc\u0131 olabilece\u011fini belirtiyor.<\/p>\n\n\n\n

Okulun Beslenme Bilimleri B\u00f6l\u00fcm\u00fc’nden Do\u00e7ent Martha Field, bir a\u00e7\u0131klamada, “D\u00fc\u015f\u00fck B12 seviyesinin daha d\u00fc\u015f\u00fck kas k\u00fctlesi ve belki de kas g\u00fcc\u00fcyle ili\u015fkili oldu\u011fu g\u00f6r\u00fcl\u00fcyor” dedi.<\/p>\n\n\n\n
Bunun nedeni belirsiz olsa da B12 eksikli\u011finin kas a\u011fr\u0131s\u0131yla ba\u011flant\u0131s\u0131 daha \u00f6nce kurulmu\u015ftu. Kas geli\u015ftirmek sadece iyi g\u00f6r\u00fcnmekle ilgili de\u011fil; kas g\u00fcc\u00fc ve k\u00fctlesi bizi yaralanmalardan korumaya yard\u0131mc\u0131 olur ve kemik kayb\u0131n\u0131 yava\u015flatabilir.<\/p>\n\n\n\n
Harvard T\u0131p Fak\u00fcltesi’nden Dr. Howard LeWine, “\u0130yi haber \u015fu ki ara\u015ft\u0131rmalar g\u00fc\u00e7 antrenman\u0131n\u0131n kemik kayb\u0131n\u0131 yava\u015flatmada rol oynayabilece\u011fini ve hatta kemik olu\u015fturabilece\u011fini g\u00f6steriyor. Bu, kemik k\u00fctlesindeki ya\u015fa ba\u011fl\u0131 azalmay\u0131 dengelemek i\u00e7in son derece faydal\u0131” dedi.<\/p>\n\n\n\n

Uzmanlar, yeti\u015fkinlerin g\u00fcnl\u00fck beslenmelerinde yakla\u015f\u0131k 2,4 mikrogram B12 vitamini almas\u0131n\u0131 \u00f6neriyor.

Harvard’a g\u00f6re, bu vitamin a\u00e7\u0131s\u0131ndan en zengin besin midye ve 85 gram\u0131nda 84 mikrogram B12 bulunuyor. Ancak midye sevmiyorsan\u0131z, 85 gram somonda 4,9 mikrogram, 170 gram ya\u011fs\u0131z sade yo\u011furtta 1,3 mikrogram ve b\u00fcy\u00fck bir yumurtada 0,6 mikrogram da alabilirsiniz.<\/p>\n\n\n\n
