ABSTRACT

Soapstone is among the first heat-resistant materials to have been used by man for the manufacture of culinary utensils, but its impact on human nutrition has merited little attention. Here, we present a preliminary evaluation of the impact of soapstone pans on the iron status in humans. Five nuns (37.6 ± 6.31y) replaced the soapstone for their traditional aluminum cookware, without any alteration of the diet itself. Comparison of the hematological data, determined before and 10 weeks after switching the pans, revealed that hemoglobin rose from 13.26 to 14.0 mg•dL-1 (p=0.0048), and hematocrit increased from 38.14 to 40.71% (p=0.0002), while the transferrin saturation index went from 28.04 to 28.96% (p=0.0147) and ferritin, from 31.5 to 34.74ìg•L-1 (p=0.0681). By simply replacing the soapstone for the traditional aluminum cookware, substantially improved the iron status in all subjects in a relatively short period of time.


La piedra-jabon (jabon-de-sastre, piedra de talco), uno de los primeros materiales termo-resistentes usados en la manufactura de utensilios culinarios, ha recibido poca atencion sobre el impacto de su uso en el estado nutricional de la poblacion. El presente estudio piloto evalua el uso de utensilios de piedra-jabon en el estado nutricional en hierro de mujeres jovenes. Cinco monjas (37,6 } 6,31 anos) reemplazaron sus tradicionales utensilios de aluminio por ollas de piedra-jabon, sin cualquier otra alteracion en la dieta. La comparacion de los parametros sanguineos, determinados antes y despues de 10 semanas de intervencion, mostro que la hemoglobina aumento, de 13,26 a 14,00 mg.dL-1 (p=0,0048) y el hematocrito, de 38,14 a 40,71 (p=0,0002), mientras el indice de saturacion de transferrina subio, de 28,04 a 28,96%, y la ferritina, de 31,50 a 34,74 ƒÊgEL-1 (p=0.0681). Se concluye que mediante la simple eliminacion de los utensilios de aluminio y su substitucion por los de piedrajabon, posibilito una substancial mejoria del estado nutricional en hierro de todos los sujetos, en un termino relativamente corto.
