OBJECTIVES MATERIAL AND METHODS RESULTS CONCLUSIONS
Study the effect of maternal diet and geographical localization in the protein and fatty acid composition in breast milk.
SPECIFIC OBJECTIVES:
The determination of Lactoferrin content in breast milk from women from Honduras, Egypt and Spain.The determination of Haptocorrin content in breast milk from women from Honduras, Egypt and Spain.The determination of long-chain fatty acid content in breast milk from women from Honduras, Egypt and Spain.The comparison of protein and fatty acid profiles of human milk samples from each origin.

MATERIAL AND METHODS
MATERIAL AND METHODS RESULTS CONCLUSIONS
Breast milk samples were analyzed from each point of origin: 8 samples from Egypt, 7 samples from Honduras and 2 samples from Spain.
These samples were taken during the 2nd to 4th month after birth

CONCLUSIONS
CONCLUSIONS
RESULTS
The differences observed in the three countries could perfectly be because of the
different diets consumed in each country. Infants in Spain ingest more LF so that
could explain a lower incidence in gastrointestinal infections, lower anemia rates,
etc. Infants in Egypt and Honduras consume more HC, so that would involve a better
neural development and lower megaloblastic anemia rates.
Infants from all three countries have a high consumption of arachidic acid which
would help with the development of the nervous system and the immune system.
