A doctoral dissertation at the University of Murcia by Patricia Weight Echarri has evaluated the effects of infant formula to mimic the composition of breast milk produced on mineral availability and composition of the intestinal microbiota of infants.
Breast milk is the ideal food for growth and development of infants during the first stage of his life, but feeding does not always possible or desirable, so it is necessary to develop infant formula to replace breastfeeding natural.
Therefore, breastfeeding is the reference used in the preparation of infant formula, which try to imitate the composition to produce their own in the infant physiological outcomes.
Currently, they are usually added a-lactalbumin and nucleotides, compounds naturally present in breast milk-which have been associated with beneficial effects such as improved growth and repair and differentiation of the gastrointestinal tract of the infant.
However, few studies examining the effect on mineral availability and composition of the intestinal microbiota, lagoon that has been supplied by Patricia Weight with his work.
The dissertation has evaluated the effect of infant formula, supplemented with a-lactalbumin, nucleotides and DHA-availability and mineral composition of the intestinal microbiota, with reference to the milk.
Regarding the evidence relating to the mineral availability, it was observed that, although the availability of minerals in human milk is higher than that of the infant formulas studied, the addition of a-lactalbumin and nucleotides improved the availability of calcium and zinc in infant formula evaluated by the cell line Caco-2.
On the other hand, the results obtained in vivo study show that infant formula supplemented beneficial changes on the composition of intestinal microbiota, closer to the composition of intestinal microbiota of infants breastfed during the first 50 days of life .
The doctoral thesis, directed by professors María del Carmen Martínez and María del Carmen Graciá Frontela Sáseta, is part of a project with the company Hero Spain, the Department of Pediatrics, University Hospital of Arrixaca and the Area of ​​Nutrition and Food Science Department of Food Technology, Nutrition and Food Science, University of Murcia.
The analysis of the intestinal microbiota was carried out in collaboration with the Dairy Institute of Asturias (CSIC).
