Nutritional meaning of dietary fibre and phytic acid in meat-based homogenised weaning foods
1997
Periago, M.J. | Ros, G. | Rincon, F. | Martínez, C.
Twenty-seven meat based homogenised weaning foods purchased in supermarkets and pharmacies in Murcia were analysed to determine the total dietary fibre (TDF) and phytic acid content. The samples were grouped according to the type of meat used: lamb, ham, chicken, veal, beef, chicken and veal, and beef and ham. In a 250 jar, the TDF ranged from 0.45 to 4.25 g, whereas the phytic acid content varied from 0.08 to 0.69 g. In general, the weaning foods studied provided a good percentage of the recommended dietary intakes (RDI) of TDF, but according to the phytate/Ca, phytate/Zn and phytate x Ca/Zn molar ratios, the phytic acid content could compromise the Ca and Zn availability in some samples. No trend was observed between TDF and phytic acid content, provided by the plant food ingredients to the weaning foods. It is clear that the selection of ingredients (vegetables, legumes and cereals) for homogenised weaning foods should be made in accordance with their contribution to TDF and phytic acid intake, in order to improve the percentage of TDF, to reduce the phytic acid content and to ensure an adequate mineral availability.
