Por lo general, las mujeres consumen menor cantidad de vitamina D de la necesaria. Por tanto, es prudente incluir dicha vitamina en la dieta o consumir pescado azul. Son conclusiones de un amplio análisis, dirigido por especialistas de la Harvard Medical School, que publica "American Journal of Clinical Nutrition".
Los investigadores hicieron un estudio retrospectivo de 72.337 mujeres posmenopáusicas, para averiguar los hábitos nutritivos y los suplementos incluidos en sus dietas, durante 18 años, desde 1980. Dichos datos se fueron actualizando varias veces durante el período de seguimiento. Se identificaron 603 fracturas de cadera, causadas por traumatismos moderados.
Los resultados mostraron que las mujeres que consumían 12,5 microgramos (o mayor cantidad) de vitamina D diariamente tenían un 37% menor de riesgo de fractura de cadera que las que consumían menos de 3,5 µg al día. Ni el consumo total de calcio, ni el de lácteos, se asoció con una reducción de riesgo de fractura de cadera .
