Resumo: | The World Health Organization considers iodine deficiency as a major worldwide cause of mental and development diseases, estimating that about 13% of the world population is affected by diseases caused by iodine deficiency. Iodine is a trace element necessary for the synthesis of thyroid hormones which, since it cannot be formed by the organism, must be taken regularly with food. Fish and shellfish are generally a good source, because the ocean contains a considerable amount of iodine. On the contrary, plants which grow in iodine-deficient soils are poor in this element, as well as meat and other animal products fed in plants low in iodine. Salt is the best way for iodine supplementation. Cooking the food with iodized salt is a desirable practice because it guarantees the presence of this element. There are also other methods to provide iodine to the general population, such as adding iodine to drinking water or taking supplements of iodine. In pregnancy is recommended iodine supplementation, except in patients with known thyroid disorders. Iodine is an essential component of thyroid hormones (T4 and T3). Inadequate iodine intake leads to inadequate thyroid hormone production. The most important consequences of iodine deficiency, in the general population are goiter and hypothyroidism, and in the severe cases, mental retardation, cretinism and increased neo-natal and infant mortality. The International Council for the Control of Iodine Deficiency Disorders (ICCIDD) formed in 1985, with the only aim of achieving optimal iodine nutrition in the world, in cooperation with UNICEF and WHO. In Portugal, recent studies show significant deficiencies in pregnancy and The Portuguese Society of Endocrinology Diabetes and Metabolism, in partnership with General Directorate of Health, proposed an iodine supplementation during pregnancy with 150-200μg/day. |

O iodo é um oligoelemento necessário na síntese de hormonas tiroideias que, uma vez que não pode ser formado pelo organismo, tem de ser ingerido regularmente com a alimentação. O peixe e o marisco são geralmente uma boa fonte, porque o mar contém um teor de iodo considerável. Pelo contrário, as plantas cultivadas em solos com deficiência de iodo são pobres neste elemento, bem como a carne e outros produtos animais alimentados com plantas pobres em iodo. O sal é o melhor veiculo para a adição de iodo. Condimentar os alimentos com sal iodado é uma prática desejável, porque nos garante a presença deste elemento. Existem também outros métodos para fornecer iodo à população em geral, tais como adicionar iodo à água potável ou tomar suplementos com iodo. Na gravidez é consensualmente recomendada a suplementação iodada, excepto em doentes com patologia tiroideia conhecida. O iodo é um componente essencial das Hormonas Tiroideias (T4 e T3). Um aporte inadequado de iodo, leva a uma produção inadequada de hormonas da tiróide. As consequências mais importantes da deficiência de iodo, na população em geral são o bócio e o hipotiroidismo e, nos casos mais graves, atraso mental, cretinismo e aumento da mortalidade neo-natal e infantil. A sobrecarga iodada de origem alimentar é raríssima. O Conselho Internacional para o controlo das doenças por deficiência de iodo (ICCIDD) surgiu em 1985, com o único propósito de conseguir uma nutrição óptima de iodo em todo o mundo, e tem colaborado com a UNICEF e com a OMS. Em Portugal existem trabalhos recentes que mostram importantes carências na gravidez e a Sociedade Portuguesa de Endocrinologia Diabetes e Metabolismo, em parceria com a Direcção Geral da Saúde, propõem a suplementação em iodo durante a gravidez com 150-200 μg/dia.Ordem dos Médicos2012-07-23info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/x-pdfhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/44oai:ojs.www.actamedicaportuguesa.com:article/44Acta Médica Portuguesa; Vol. 25 No. 3 (2012): May-June; 174-178Acta Médica Portuguesa; Vol. 25 N.º 3 (2012): Maio-Junho; 174-1781646-07580870-399Xreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/44https://www.actamedicaportuguesa.com/revista/index.php/amp/article/view/44/46Santana Lopes, MariaJácome de Castro, JoãoMarcelino, MafaldaOliveira, Maria JoãoCarrilho, FranciscoLimbert, Edwardinfo:eu-repo/semantics/openAccess2022-12-20T10:55:45Zoai:ojs.www.actamedicaportuguesa.com:article/44Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:16:21.474133Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
