ABSTRACT
Choline is an essential nutrient; dietary deficiency of choline is associated with impaired liver function, elevated blood concentrations of alanine aminotransferase, creatinine phosphokinase and homocysteine. There is also depletion of acetylcholine concentration in the brain, leading to deficit in memory function. The authors examined the dietary intake of choline in groups of students at the Mona Campus of the University of the West Indies. Sixty-two medical students (first and second years) and biochemistry students (final year) were recruited They were asked to (including amounts) record all foods and drinks consumed for three days (two weekdays and one weekend day). The sheets were collected and the amount of choline and betaine (a metabolite of choline) consumed were calculated Dietary intake of folate was also evaluated. The analysis revealed that 86.2of the females and 90.9of the males reported diets that delivered less daily choline than the adequate intake quoted by the Institute of Medicine of the National Academy of Sciences, USA (425-550 mg/day). The betaine consumption ranged between 25 to 620 mg/day (no adequate intake documented) and the folate consumed was more than the recommended daily allowance of folate (180-200 microg/day). The dietary intake of choline in the majority of students is below adequate intake. Although folate also serves similar functions to choline, it is unlikely that it can substitute for choline in all physiological aspects and therefore the implications of low dietary choline need further investigation.
RESUMEN
La colina es un nutriente esencial. La deficiencia dietética de colina está asociada con el deterioro de la función hepática, así como con elevadas concentraciones en sangre de alanina-aminotrans-ferasa, creatinina-fosfoquinasa y homocisteína. Asimismo, se produce un agotamiento de la concentración de acetilcolina en el cerebro, lo cual conduce a un déficit en la función de la memoria. Los autores examinaron la ingestión dietética de colina en grupos de estudiantes del campus de Mona de la Universidad de West Indies. Se reclutaron sesenta y dos estudiantes de ciencias médicas (de primer y segundo año) y bioquímica (FAltimo año). Se les pidió que tomaran notas (incluyendo cantidades) de todos los alimentos y bebidas consumidos en tres días (dos días de entre semana y un día de fin de semana). Se recogieron las anotaciones y se calculó el consumo de colina y betaína (un metabolito de la colina). Se evaluó la ingestión de folato. El análisis reveló que el 86.2% de las mujeres y el 90.9% de los hombres, reportaron dietas cuyo suministro de colina por día se hallaba por debajo del consumo adecuado indicado por el Instituto de Medicina de la Academia Nacional de Ciencias de Estados Unidos (425–550 mg/día). El consumo de betaína osciló de 25 a 620 mg/día (no existe documentación sobre el consumo adecuado), en tanto que el folato consumido estuvo por encima de la ingestión diaria de folato recomendada (180 – 200 ug/día). El consumo dietético de colina de la mayoría de los estudiantes está por debajo del consumo adecuado.
