Relación entre el consumo de ácidos grasos y su contenido en la leche materna madura de mujeres lactantes de la ciudad de Medellín, Colombia

RESUMEN El contenido de ácidos grasos en la leche materna madura varía dependiendo del estado nutricional de la madre, de la dieta materna antes de la gestación y durante la gestación, el tiempo de lactancia, entre otros. Por lo anterior, este estudio pretende caracterizar la ingesta dietaría de madres donantes de leche materna madura y determinar el perfil de ácidos grasos con énfasis en los ácidos grasos poliinsaturados de cadena larga. Para ello, se contó con la participación de 50 madres lactantes y donantes las cuales se extrajeron cada una, 60 ml de leche materna madura, para determinar el perfil de ácidos grasos por cromatografía de gases. También, se determinó el consumo de ácidos grasos por frecuencia de consumo y por consumo habitual. Se reporto que en la leche materna madura prima el contenido de ácidos grasos insaturados (62%) sobre los saturados (38%), además, el total de grasa encontrado, fue superior al reportado normalmente en la literatura. Finalmente, no se evidencio correlación entre el consumo de ácidos grasos en la dieta de las madres y el contenido de estos en la leche materna madura, aspecto coherente con el contenido nutricional adecuado que debe aportar este alimento al lactante sin afectar su salud.

ABSTRACT The content of fatty acids in mature breast milk varies depending on the nutritional status of the mother, maternal diet before pregnancy and during pregnancy, and breastfeeding time, among others. This study aimed to characterize the dietary intake of donor mothers of mature breast milk and determine fatty acid profile with emphasis on long-chain polyunsaturated fatty acids. Fifty donor mothers were involved, each one provided 60 ml of mature breast milk; fatty acid profile was determined by gas chromatography. The consumption of fatty acids was determined by frequency of consumption and by habitual semiquantitative consumption. We found that unsaturated fatty acid content was greater than saturated (62%) in mature breast milk and total fat was higher than that normally reported in the literature. Finally, there was no correlation between the consumption of fatty acids in the diet of the mothers and the content of these in mature breast milk, which is consistent with the adequate nutritional content that this food should provide to the infant without affecting their health.

The study progress on lipid condensation or accumulation theory / 国际中医中药杂志

In recent years, there's a new theory of lipid condensation or accumulation being the etiology for obstruction of qi in the chest result in heart disease. The theory believes that thick lipid exists in meridians. If one takes too much fatty diet, there will be lipid condensation or accumulation, resulting in disturbance of qi transformation in meridians,. Scholars explore the relationship of preventive treatment of disease by traditional Chinese medicine with lipid condensation or accumulation theory. This enriches the etiology of TCM.
