Se estudió la variación de la capacidad antioxidante y compuestos fenólicos de hierbas aromáticas durante el proceso para obtener un filtrante con esteviósido como edulcorante natural y se encontró que las hierbas aromáticas aumentan su capacidad antioxidante reportando en mM Trolox /100g b.s.: hierba luisa 2.049; 5.42 y 5.45, menta 4.847; 12.40 y 12.37, malva 1.011; 2.83 y 2.97, malva olorosa 5.354; 35.40 y 36.74, cola de caballo 1.254; 4.01; 4.6; en las etapas de materia prima, secado y molienda respectivamente; la malva olorosa presentó el mayor contenido de capacidad antioxidante. Las Hierbas aromáticas aumentan los compuestos fenólicos durante el proceso de obtención del filtrante reportando en mg de ácido gálico/100g de muestra b.s: hierba luisa 1745.1; 2631.29 y 2706.48, menta 5601.42; 6989.91y 7063.26, malva 4058.79; 6038.63y 5881.26, malva olorosa 5150.44; 6669.02 y 6606.38, cola de caballo 645.68; 1017.08 y 1048.40; en las etapas de materia prima, secado y molienda respectivamente; la menta fue la que presentó el mayor contenido de compuestos fenólicos; la mejor dosificación de esteviósido es aplicando 5% respecto a las hierbas y que la mejor formulación del filtrante. El filtrante que reporto la siguiente composición físico-química: humedad 5.69 %, proteínas 12.79%, grasa 2.39%, carbohidratos 48.3%, cenizas 14.01%, fibra 16.82% compuestos fenólicos 2973.76 mg de ácido gálico/100g de muestra b.s. y capacidad antioxidante 7.34mM Trolox/100g b.s., el valor de monocapa molecular: 0,073g de agua/g b.s. correspondiente a una actividad de agua (aw) de 0.219Palabras claves: Compuestos fenólicos, capacidad antioxidante.

It is widely accepted by the scientific community that the world has begun to warm as a result of human influence. The accumulation of greenhouse gases in the atmosphere, arising primarily from the combustion of carbon fossil fuels and agricultural activities, generates changes in the climate. Indeed various studies have assessed the potential impacts of climate change on human health (both negative and positive). The increased frequency and intensity of heat waves, the reduction in cold-related deaths, the increased floods and droughts, and the changes in the distribution of vector-borne diseases are among the most frequently studied effects. On the other hand, climate change differs from many other environmental health problems because of its gradual onset, widespread rather than localized effect, and the fact that the most important effects will probably be indirect. Some recent and important publications show that only the collaboration between the meteorological and the public health communities can help us to thoroughly study the link between climate and health, thus improving our ability to adapt to these future changes. The aim of this editorial is to give different perspectives on a widely discussed topic, which is still too complicated to be addressed to a satisfactory extent. Moreover, it is necessary to underline the importance of using new biometeorological indices (i.e. thermal indexes, etc.) for future projections, in order to reduce the impacts of negative outcomes, protecting the population through adaptation measures and public awareness.

The presence of ENSO Events in South America is felt in two ways: a) through its effects on both the atmosphere and ocean systems, and b) through its impacts on natural ecosystems (both marine and terrestrial) and on societal and economical sectors (like fisheries, health, and agriculture). The main effects of El Niño/La Niña are: Increment/Decrement of sea surface temperature and salinity, Increment/Decrement of sea level and wave activity, Increment/Decrement of air temperature and amount of ultra violet radiation reaching the surface of the earth, and Changes in the rainfall and evaporation patterns. It is not easy to make an "average" pattern of ENSO impacts for a variety of reasons: the impacts depend greatly of factors like geographical extent and position of the oceanic anomalies, and intensity and timing of the anomalies; also the influence of social, economic and political structures determines whether climate anomalies caused by ENSO in a particular region will lead to severe societal and economical impacts. The scientific community also plays a potential role in the extent of the impacts that ENSO can produce, if scientists can provide information on the impact of the presence of ENSO by identifying and focusing on its precursors, intervention could be taken early enough. There is however, something to be said against that: information can be misleading, target inappropriate at-risk groups, or generate a false sense of security.
