Etiquetado nutricional, ¿qué se sabe del contenido de sodio en los alimentos?

Abstract

ResumenLa ingesta excesiva de sodio es una característica de nuestra alimentación, es un factor de riesgo de hipertensión arterial y de muerte por complicaciones cardiovasculares. Los alimentos procesados aportan el mayor contenido de sodio en la dieta y su cantidad aparece en las etiquetas de los envases. Este estudio fue diseñado para conocer si los consumidores leen y entienden la información relacionada con el contenido de sodio anotado en las etiquetas, si tienen conocimiento de la relación sodio-sal, de la cantidad máxima de sal reco-mendada para el consumo diario y si obtienen información relacionada en la consulta médica.Material y métodoEstudio descriptivo transversal de los resultados de una encuesta realizada a adultos mayores de 19 años en la sala de espera de las consultas de Medicina Interna Adulto y Pediatra en Clínica Las Condes en el período 2012.Resultados308 (89,2%) de un total de 345 encuestas fueron respondidas correctamente. 93,8% de las mujeres y 80,0% de los hombres (p<0,001) se preocupan por una alimenta-ción saludable, 70,4% refirió conocer la diferencia entre sodio y sal. 39,8% reconoció leer siempre las etiquetas, 52,2% sólo a veces y 8% nunca. El mayor grado de conocimiento referido por los encuestados fueron aquellos que reportaron leer las etiquetas, con una diferencia significativa con aquellos que reportaron no leer las etiquetas (p=0,001). 30,5% de las mujeres y 28,6% de los hombres sabía cuál era la cantidad de sal aconsejada para el consumo diario. El 53,3% no ha re-cibido información médica acerca de la importancia del sodio en la dieta.ConclusiónLa mayoría de los encuestados manifestó su interés por una alimentación sana. Sin embargo, sólo una minoría refirió leer las etiquetas, conocer la cantidad de sal diaria recomendada y recibir información sobre la importancia del sodio en la alimentación.SummaryExcessive sodium intake is a risk factor for hypertension and cardiovascular death. Processed foods provide the highest sodium content in the diet and the amount is shown on the package labels. The aim of this study was to know if consumers read and understand the information related to sodium listed on the labels, are aware about the relation between sodium and salt, know the maximum amount of salt recommended for daily consumption and if they receive medical advice about the importance of dietary sodium intake.Material and methodA descriptive cross-sectional study was performed. The information was collected through a survey given to adults older than 19 years old in the waiting room consultations of internal medicine and pediatrics at Clínica Las Condes during 2012.Results308 (89,2%) of a total of 345 surveys were answered completely. 93,8% of women and 80,0% of men (p<0,001) care about healthy eating, 70,4% reported knowing the difference between sodium and salt. 39,8% referred to read always the labels, 52,2% only sometimes and 8% never. The highest degree of knowledge referred by respondents were those who reported reading labels, with a significant difference to those who reported not reading labels. (p=0,001). 30,5% of women and 28,6% of men were aware about the recommended dietary salt intake. 53,3% reported not receiving professional advice about the relevance of sodium in the diet.ConclusionMost of the respondents expressed their interest in healthy eating. However, only a minority referred to read the labels, to know the daily recommended dietary salt intake and to receive information about the importance of sodium in the diet.
