RESUMEN

Introducción: En caso de deficiencia de zinc, se limitará la síntesis muscular y ósea. Los estudios en humanos sobre zinc y salud ósea son pocos y no se han publicado comentarios sobre este tema. Por lo tanto, el objetivo de esta revisión narrativa es considerar el estado de la técnica sobre la correlación entre el zinc en la sangre, la ingesta diaria de zinc, la suplementación de zinc y la densidad mineral ósea. Material y métodos: Se realizó una revisión narrativa. Resultados: Esta revisión incluyó 16 estudios elegibles: ocho se refieren al zinc en sangre; tres estudios se refieren a la ingesta de Zn y cinco estudios se refieren a la suplementación de Zn. Conclusión: Los niveles de zinc en sangre parecen ser más bajos en sujetos con patología relacionada con el metabolismo óseo. En cuanto a la ingesta diaria de zinc, una alta proporción de la población, más de 20%, parece estar en riesgo de tener una ingesta inadecuada de zinc. La literatura sugiere que una ingesta insuficiente de zinc (menos de 3 mg/día) podría ser un factor de riesgo de fracturas y para el desarrollo de osteopenia y osteoporosis. La suplementación con zinc (40-50 g/día) podría tener efectos beneficiosos sobre la salud ósea para mantener la densidad mineral ósea y una curación más rápida en caso de fracturas, con resultados aún mejores en situaciones de reducción de la ingesta de zinc a través de los alimentos.
