Resumo
O objetivo desse estudo foi avaliar a biodisponibilidade de ferro e zinco adicionados à bebida de café solúvel em mulheres saudáveis, utilizando a resposta da concentração plasmática desses micronutrientes em função do tempo (6 horas). Três tratamentos foram administrados: café solúvel; café solúvel enriquecido e solução de micronutrientes. A biodisponibilidade relativa foi determinada pela razão percentual da área abaixo da curva (AUC) do café solúvel enriquecido, corrigida pela AUC do café solúvel, e a AUC da solução de micronutrientes. O ferro e o zinco adicionados à bebida de café apresentaram biodisponibilidades relativas de 45% e 83%, respectivamente. Essa biodisponibilidade foi de magnitude comparável à observada para outros alimentos enriquecidos relatados na literatura.
The aim of this study was to evaluate in healthy women the bioavailability of iron and zinc contained in an enriched instant coffee, using the plasma response over time (6 hours). Three treatments were carried out: instant coffee; enriched instant coffee and a micronutrients solution. The relative bioavailability was determined as the percent ratio of the area under the curve (AUC) of soluble coffee enriched corrected by the AUC of instant coffee and by the AUC of the micronutrients solution. The iron and zinc added to instant coffee beverage showed relative bioavailabilities of 45% and 83%, respectively. This magnitude was comparable to that observed in other enriched food products reports in the literature.
