Omega-3 fatty acids, especially long-chain omega-3 fatty acids, have been associated with potential health benefits for chronic disease prevention. Our previous studies found that dietary omega-3 fatty acids could accumulate in the meat and eggs in a duck model. This study was to reveal the effects of various dietary fats on fatty acid profile and conversion of omega-3 fatty acids in duck liver. Female Shan Partridge Ducks were randomly assigned to five dietary treatments, each consisting of 6 replicates of 30 birds. The experimental diets substituted the basal diet by 2% of flaxseed oil, rapeseed oil, beef tallow, or fish oil, respectively. In addition, a dose response study was further conducted for flaxseed and fish oil diets at 0.5%, 1%, and 2%, respectively. At the end of the five-week treatment, fatty acids were extracted from the liver samples and analyzed by GC-FID. As expected, the total omega-3 fatty acids and the ratio of total omega-3/omega-6 significantly increased in both flaxseed and fish oil groups when compared with the control diet. No significant change of total saturated fatty acids or omega-3 fatty acids was found in both rapeseed and beef tallow groups. The dose response study further indicated that 59–81% of the short-chain omega-3 ALA in flaxseed oil-fed group was efficiently converted to long-chain DHA in the duck liver, whereas 1% of dietary flaxseed oil could produce an equivalent level of DHA as 0.5% of dietary fish oil. The more omega-3 fatty acids, the less omega-6 fatty acids in the duck liver. Taken together, this study showed the fatty acid profiling in the duck liver after various dietary fat consumption, provided insight into a dose response change of omega-3 fatty acids, indicated an efficient conversion of short- to long-chain omega-3 fatty acid, and suggested alternative long-chain omega-3 fatty acid-enriched duck products for human health benefits.

O objetivo deste estudo é descrever os benefícios do consumo dos ácidos graxos poli-insaturados durante a gestação e fatores associados no desenvolvimento infantil. Trata-se de uma revisão bibliográfica integrativa, a partir da análise de artigos científicos indexados nas bases de dados MedLine, Scielo, Science Direct e Google acadêmico, com recorte temporal de dez anos (2010-2020). Os descritores utilizados foram: ácido graxopoli-insaturados de cadeia longa; ômega 3; ômega 6; gestante e lactente, no idioma português e inglês, com o auxílio do operador boleano “AND”. Os resultados da pesquisa, após os critérios de inclusão e exclusão, obtiveram um total de 12 artigos. Os estudos demonstraram que os ácidos graxos poli-insaturados de cadeia longa (LCPUFA), tais como os das séries ômega 3 e ômega 6, em especial ácido docosahexaenóico e ácido eicosapentaenóico são fundamentais para o crescimento e desenvolvimento infantil, e tem função primordial na formação e no funcionamento do sistema nervoso central e da retina, e melhora do peso ao nascer. Além disso, os LCPUFA atuam nas gestantes reduzindo riscos de prematuridade, possui função antiinflamatória e antioxidante, reduz o estresse oxidativo, e controla os sintomas depressivos pré e pós-gestação. Conduto, são necessários mais estudos que abordem as quantidades adequadas para o período gestacional favorável à saúde materno-infantil.AbstractThis study aims to describe the benefits of consuming polyunsaturated fatty acids during pregnancy and the associated factors in child development. This is an integrative bibliographic review, based on the analysis of scientific articles indexed in the MedLine, Scielo, Science Direct and Google academic databases, with a ten-year period (2010-2020). The descriptors used were: Long chain fatty polyunsaturated acid; Omega 3; Omega 6; pregnant woman and infant in Portuguese and English, with the assistance of the Boolean operator “AND”. The results of the research, after the inclusion and exclusion criteria, obtained a total of 12 articles. Studies have shown that long-chain polyunsaturated fatty acids (LCPUFA), such as those from the omega 3 and omega 6 series, especially docosahexaenoic acid and eicosapentaenoic acid, are essential for child growth and development, and have a primary role in the formation and in the functioning of the central nervous system and the retina and improves birth weight. In addition, in pregnant women it works by reducing the risk of prematurity. The LCPUFA have an anti-inflammatory and antioxidant function, reduce oxidative stress, and control depressive symptoms before and after pregnancy. However, further studies are needed to address the appropriate quantities for the gestational period favorable to the mother-child health.Keywords: Polyunsaturated fatty acid; Omega 3; Omega 6; Pregnant; Infant.ResumenEl objetivo de este estudio es describir los beneficios de consumir ácidos grasos poliinsaturados durante el embarazo y los factores asociados en el desarrollo infantil.

Los estudios han demostrado que los ácidos grasos poliinsaturados de cadena larga (AGPICL), como los de las series omega 3 y omega 6, especialmente el ácido docosahexaenoico y el ácido eicosapentaenoico, son esenciales para el crecimiento y desarrollo infantil y tienen un papel principal en la formación y en el funcionamiento del sistema nervioso central y la retina, y mejora del peso al nacer. Además, los AGPICL actúan en mujeres embarazadas reduciendo el riesgo de prematurez, tienen una función antiinflamatoria y antioxidante, reducen el estrés oxidativo y controlan los síntomas depresivos antes y después del embarazo. Sin embargo, se necesitan más estudios para abordar las cantidades apropiadas para el período gestacional favorable a la salud de la madre y su hijo.Palabras Clave: Ácido graso poliinsaturado; Omega 3; Omega 6; Embarazada; Infante.
