Selenium takes a special place among the trace elements. Toxic action is known as well as deficiency syndroms and the optimal range of beneficial action seems to be smaller than for the other trace elements. Supported by epidemiological studies (1,2) there is an increasing interest in the deficiency situation of selenium in human nutrition and health. However, the treatment of a lowered selenium status of the organism is still a problem due to the small margin between the toxic and physiological dose response. In order to define the levels of a safe and adequate selenium dosage in prophylaxis and therapy information is needed regarding the influence of high selenium intakes and the physiological activity of other essential trace elements or their uptake rate. However, few data are presented in the literature on the consequences of longterm human exposure to elevated dietary selenium levels.

In order to study effects of high selenium ingestion in humans and the relationships between this element and other trace elements a research program was started in 1982 on a collaborative basis between the Hahn-Meitner-Institut Berlin and the national Venezuelan foundation for the investigation of the health status of the population FUNDACREDESA.

A field investigation was carried out in the seleniferous area of Villa Bruzual in Venezuela. In this natural laboratory Jaffé (3 )started 14 years ago a clinical and biochemical investigation of school children in order to study possible health risks. In the present study the examination was extended to adults, elderly persons and lactating mothers. A total of 134 persons was examined and samples of blood, hair, breast milk and aliquots of the families meal were collected.

Recuerda que, en los alimentos para niños y niñas menores de 2 años no hay que añadir azúcar. Solo deben recibir el azúcar que proviene de las frutas y vegetales que integran su menú. Esto garantizará un desarrollo más saludable.


¡Cuida tu Consumo de Azúcar!
El exceso de azúcares se almacena en el organismo en forma de grasa, si estas reservas no se usan pueden acumularse y producir problemas de salud, como: incremento de presión arterial, riesgo de infartos y complicaciones vasculares.

La Guía Nutricional 2022, contiene recetas que contribuyen con el equilibrio y variedad de la alimentación, el consumo de frutas y vegetales, regular azúcares y sal, entre otros, con el objetivo de orientar a la familia sobre cómo cuidar su salud.
