FERNANDEZ-PALACIOS, Lorena et al. Contribution of bioavailable iron and zinc to the diet of Honduran children under 24 month. Nutr. Hosp. [online]. 2017, vol.34, n.2, pp.290-300. ISSN 1699-5198.


In the present study we analyzed 18 baby food (10 made from traditional Honduran recipes, and 8 industrial baby food sold in that country) involving the staple food of Honduran excluded infants breast milk and infant formulas.

Material and methods:

The content and bioaccesibility (soluble and dialysable fractions) of Fe and Zn were determined. For this in vitro gastrointestinal digestion in a first phase of gastric digestion (pepsin) followed by a second phase of intestinal digestion (with pancreatin and bile salts) was simulated. The atomic absorption spectrometry mineral content measured in soluble and dialyzable fractions.


Traditional porridges from Honduras (PTH) showed low density of micronutrients being the PTH prepared based on "rice with beans and greens", "rice with ground beans" and "beans with banana" which had a higher content values of 1.96, 1.56, and 1.46 mg Fe/100 g, respectively, although in vitro availability values below 50% of its content. For Zn in these recipes, the values found were very low being below the detection limit. In relation to industrial porridges (PIH), those of "rice", "wheat with milk" and "5 cereals" they had a higher content of Fe (9.4, 8.53 and 7.56 mg Fe/100 g, respectively). Its availability in vitro was greater than 70% in all cases. PIH Zn showed values of 1.36, and 0.99 mg Zn/100 g samples of "wheat with milk" and "wheat with honey", respectively, and increased availability of 75%.


It is shown that PTH have some limitations in its formulation that makes the selected micronutrients are in fewer and even less bioaccessible, compared with PIH, so review is recommended to avoid supplementation of these micronutrients and help improve the nutritional status of the child population as Honduran model country in Central America.
