#  A vitamina B12 na dieta vegan

![A vitamina B12 na dieta vegan](https://ivu.org/images/legacy/history/banners/portuguese-trans-vrg-b12.png) | **A vitamina B12 na dieta vegan**     Reed Mangels, Ph.D, R.D. (nutricionista)     **[Vegetarian Resource Group](http://www.vrg.org/)**     **Tópicos deste artigo:**Sumário    A necessidade de vitamina B12    Possíveis fontes de vitamina B12    Boas fontes vegan de vitamina B12    Notas bibliográficas  Extraído do livro *Simply Vegan: Quick Vegetarian Meals*, de Debra Wasserman. Seção sobre nutrição de Reed Mangels Ph.D., R.D. (ISBN 0-931411-20-3)  **Sumário**  A necessidade de vitamina B12 é muito pequena. As fontes não-animais incluem cereais da marca Grape-Nuts (um pouco mais de meia xícara atende à dose diária recomendada, ou DDR, de um adulto), Red Star Vegetarian Support Formula ou levedura nutritiva T-6635+ (um pouco menos de uma colher de sopa atende à DDR de um adulto) e leite de soja fortificado com vitamina B12. Para mulheres grávidas e que estejam amamentando, bebês e crianças, são especialmente importantes boas fontes de vitamina B12 na dieta.  **A necessidade de vitamina B12**  A vitamina B12 é necessária na divisão celular e na formação do sangue. Alimentos vegetais não contêm vitamina B12, exceto quando contaminados por microorganismos. Assim, os vegans precisam procurar outras fontes de vitamina B12 em sua dieta. Embora a necessidade mínima de vitamina B12 seja bem pequena, de um milionésimo de grama (1 micrograma) por dia para adultos \[1\], a deficiência de vitamina B12 é um problema muito sério que acaba    causando danos irreversíveis aos nervos. Vegans prudentes incluem fontes de vitamina B12 em suas dietas. No entanto, a deficiência de vitamina B12 é na verdade bastante rara, mesmo em pessoas que são vegans há muito tempo.  Normalmente a vitamina B12 é secretada no intestino delgado junto com a bile e outras secreções e reabsorvida, mas isso não aumenta o estoque de vitamina B12 do organismo. Já que pequena quantidade da vitamina não é reabsorvida, é possível que o estoque de vitamina B12 acabe se esgotando. No entanto, devemos ser bastante eficientes na reutilização da vitamina B12, pois esta deficiência é rara.  As bactérias do trato intestinal humano fabricam vitamina B12. A maioria dessas bactérias está no intestino grosso. Aparentemente a vitamina B12 não é absorvida no intestino grosso \[1\].  **Possíveis fontes de vitamina B12**  Algumas bactérias do intestino delgado produzem vitamina B12 \[12\]. A quantidade de vitamina B12 produzida não parece ser adequada para impedir a deficiência da vitamina \[3\].  Embora alguns vegans possam conseguir vitamina B12 por não lavarem as mãos direito, esta não é uma boa fonte. Os vegans que comiam anteriormente alimentos de origem animal podem ter estoques de vitamina B12 capazes de durar 20 ou 30 anos \[1\] ou mais. Mas pessoas que são vegans há muito tempo, bebês, crianças e mulheres grávidas ou em lactação (por causa do maior consumo) devem tomar cuidado especial para conseguir vitamina B12 em quantidade suficiente.  **Boas fontes vegans de vitamina B12**  Conhecem-se algumas boas fontes vegans de vitamina B12. A marca norte-americana de levedura nutritiva Red Star T-6635+ foi testada e comprovou-se que contém vitamina B12 ativa. Nos Estados Unidos encontra-se muitas vezes esta marca de levedura rotulada como Vegetarian Support Formula, com ou sem T-6635+ entre parênteses depois do novo nome. É uma fonte confiável de vitamina B12. A levedura nutritiva, Saccharomyces cerevisiae, é um fermento alimentar cultivado em solução de melado, vendido na forma de flocos ou pó amarelo. Seu sabor lembra o do queijo. A levedura nutritiva é diferente do levedo de cerveja e da levedura seca ou torula. Pode muitas vezes ser usado por pessoas sensíveis a outros levedos ou fermentos.  A DDR de vitamina B12 para adultos (que inclui um fator de segurança) é de 2,4 microgramas por dia \[4\]. Um pouco menos de uma colher de sopa da levedura nutritiva Vegetarian Support Formula (Red Star T-6635+) fornece 2,4 microgramas de vitamina B12. Várias receitas deste livro usam levedura nutritiva.  Outra fonte de vitamina B12 são os cereais fortificados. Por exemplo, a marca norte-americana Grape-Nuts contém vitamina B12, e um pouquinho mais de meia xícara de Grape-Nuts ou 1 xícara e 1/3 de Flocos Grape-Nuts fornecem 2,4 microgramas de vitamina B12. Recomendamos verificar o rótulo de sua marca predileta de cereal, já que é sabido que muitos fabricantes pararam de adicionar B12.  Outras fontes de vitamina B12 são o leite de soja fortificado com B12, sucedâneos da carne fortificados com B12 (alimentos feitos de glúten de trigo ou de soja para simular carne, frango ou peixe) e suplementos de vitamina B12. Há suplementos vitamínicos que não contêm produtos animais.  Os vegans que preferirem usar um suplemento de vitamina B12, isolado ou junto a outras vitaminas, deveriam usá-lo pelo menos várias vezes por semana. Mesmo que um suplemento contenha muito mais que o nível recomendado de vitamina B12, quando se ingere muita vitamina B12 parece que a absorção é reduzida. Isso significa que, para atender à sua necessidade, você deve tomar a vitamina várias vezes por semana.  Cita-se muitas vezes que o tempê, o misso e as algas contêm grande quantidade de vitamina B12. Mas esses produtos não são fontes confiáveis porque a quantidade de vitamina B12 presente depende do tipo de processamento sofrido pelo alimento \[1, 5\]. O método padrão de medir a vitamina B12 em alimentos avalia a forma ativa e a inativa da vitamina. A    forma inativa (também chamada de "análogos") na verdade interfere com a absorção e o metabolismo normais da vitamina B12. Alimentos fermentados e algas marinhas podem conter mais vitamina B12 inativa do que ativa.  Aparentemente, encontra-se alguma vitamina B12 em vegetais cultivados organicamene, mas em quantidade muito pequena. Segundo um estudo \[7, 8\], seria necessário comer mais de 23 xícaras de espinafre cultivado organicamente para atender à DDR de vitamina B12 para um adulto. Não se pode depender do produto como fonte confiável de vitamina B12 porque o nível da vitamina nas plantas varia muito, dependendo do tipo de planta e do solo    onde é cultivada. Além disso, pode haver análogos da vitamina B12 no solo que serão absorvidos pelas plantas. Se estes análogos estiverem presentes, poderão interferir com a incorporação de vitamina B12 pela planta ou com a utilidade da vitamina B12 da planta para seres humanos.  **Notas bibliográficas**  1\.
