Acidos Grasos Omega 6

¿Qué es?

Los ácidos grasos omega 6 son tipos de grasas. Algunos de los tipos de grasas se encuentran en los aceites vegetales, los que incluyen el maíz, la semilla de onagra, el cártamo y los aceites de soja. Otros tipos de ácidos grasos omega 6 se encuentran en la semilla de la grosella negra, en las semillas de borraja y en los aceites de onagra.

Los ácidos grasos omega 6 se usan para muchas afecciones, pero hasta el momento, la mejor información científica indica que el poner ácido araquidónico (un ácido graso omega 6 determinado) en las fórmulas para lactantes no mejora el desarrollo de los infantes. No se han hecho suficientes investigaciones sobre el uso de los ácidos grasos omega 6 para poder determinar si son eficaces para otros usos.

Los ácidos grasos omega 6 se usan para reducir el riesgo de enfermedades del corazón, para reducir los niveles del colesterol total, para reducir los niveles del colesterol “malo” (LDL) y para aumentar los niveles del colesterol “bueno” (HDL) y también para reducir el riesgo de cáncer.

La mayor parte de la información que tenemos sobre los suplementos de ácidos grasos omega 6 son el resultado de haber estudiado específicos ácidos grasos omega 6 o aceites de plantas que contienen ácidos grasos omega 6. Vea el listado separado para el aceite de onagra.

¿Qué tan efectivo es?

Natural Medicines Comprehensive Database (La Base Exhaustiva de Datos de Medicamentos Naturales) clasifica la eficacia, basada en evidencia científica, de acuerdo a la siguiente escala: Eficaz, Probablemente Eficaz, Posiblemente Eficaz, Posiblemente Ineficaz, Probablemente Ineficaz, Ineficaz, e Insuficiente Evidencia para Hacer una Determinación.

La clasificación de la eficacia para este producto es la siguiente:

Posiblemente ineficaz para...

  • Mejorar el desarrollo mental o el crecimiento en bebés. Agregar ácido araquidónico (un ácido graso omega 6) a la leche maternizada no parece mejorar el desarrollo mental o el crecimiento en bebés de hasta 18 meses.
  • Esclerosis múltiple (EM). La ingesta de ácidos grasos omega 6 no parece prevenir el avance de la EM.

Insuficiente evidencia para hacer una determinación para...

  • Trastorno por déficit de atención con hiperactividad (TDAH). La investigación preliminar sugiere que la ingesta de una combinación de ácidos grasos omega 3 y omega 6 no mejora los síntomas del TDAH en la mayoría de los niños.
  • Inflamación de los párpados debido a un problema en las glándulas sebáceas de los párpados. La investigación preliminar sugiere que la ingesta de un producto específico (Medilar Fidia Oftal Bausch & Laomb Pharmaceuticals) que contiene ácidos grasos omega 6 una vez por día durante 180 días acompañado de la limpieza de los párpados puede mejorar la visión borrosa, la obstrucción de las glándulas sebáceas y la inflamación de los párpados en personas con inflamación en los párpados debido a un problema en las glándulas sebáceas de los párpados.
  • Trastorno del desarrollo de la coordinación (TDC). La investigación preliminar sugiere que la ingesta de una combinación de ácidos grasos omega 3 y omega 6 durante 3 meses puede mejorar la lectura, el deletreo y el comportamiento, pero no la coordinación o los movimientos en niños con TDC.
  • Cirugía ocular. La investigación preliminar sugiere que la ingesta de un comprimido que contiene un ácido graso omega 6, además de betacaroteno y otros ingredientes, pude mejorar la producción de lágrimas y mejorar la recuperación del ojo después de una cirugía ocular con láser.
  • Reducción del riesgo de enfermedades del corazón.
  • Disminución de los niveles del colesterol malo (LDL).
  • El aumento de los niveles del colesterol bueno (HDL).
  • Reducción del riesgo de cáncer.
  • Otras afecciones.
Se necesita más evidencia para aprobar la eficacia de los ácidos grasos omega 6 para estos usos.

¿Cómo funciona?

No hay suficiente información disponible para saber como funcionan los ácidos grasos omega 6.

¿Hay preocupación por la seguridad de su uso?

Los ácidos grasos omega 6 son PROBABLEMENTE SEGUROS cuando los consumen los adultos y niños mayores de un año como parte de una dieta en cantidades entre 5 y 10% de las calorías diarias. Sin embargo, no hay suficiente información disponible para saber si los ácidos grasos omega 6 son seguros para su uso como medicina.

Advertencias y precauciones especiales:

Embarazo y lactancia: Los ácidos grasos omega 6 SON PROBABLEMENTE SEGUROS cuando se los consumen como parte de una dieta en cantidades entre 5 y 10% de las calorías diarias. No existe suficiente información confiable sobre si resulta segura la ingesta de suplementos de ácidos grasos omega 6 durante el embarazo o la lactancia. Stay on the safe side and avoid use. o se tiene suficiente información acerca de la seguridad del uso de los ácidos grasos omega 6 durante el embarazo y la lactancia. Sea precavida y evite su uso.

Triglicéridos (un tipo de colesterol) altos: Los ácidos grasos omega 6 pueden aumentar los niveles de los triglicéridos. No use ácidos grasos omega 6 si sus triglicéridos están muy altos.

¿Existen interacciones con medicamentos?
