Breast milk nourishes the brain of the babies early
– Reported, June 11, 2013
An investigation of Brown University in the U.S.. UU., Revealed that the benefits of breastfeeding outweigh those of the formula and also are greater, the longer the period of breastfeeding the child. This is the first study to analyze, using magnetic resonance imaging (MRI), breast-related differences in brain development of healthy children.
The technique examines the myelin, the tissue that protects nerve endings and accelerates the electrical impulses that travel through the brain. Myelin communicates with the different brain areas, so that a healthy amount of fatty material associated with neuronal better performance.
Laboratory researchers Baby Advanced Scanning at Brown University, examined the brains of 133 children aged ten months and four years of age, while they slept. To reach these conclusions, the children were grouped into three categories: those fed only breast milk, formula one or a combination of both. The differences between the three groups were significant after two years of age, when the amount of myelin exclusive breastfeeding child exceeded 20% to 30% of the other two groups.
The imaging results were supported by basic cognitive tests. They found a better use of language, visual perception and motor skills in the exclusive breastfeeding group. Scientists were surprised, then, even if you knew the enhancing effect of breast milk on intelligence of children, did not believe that was evident even at a young age.
According to this organization, breastfeeding saves 1.5 million lives a year. Why? The answer is simple. Breast milk contains antibodies that protect children from common diseases such as pneumonia and diarrhea, leading causes of death in the world during the first years of life.
Furthermore, according to the National Institute of Health USA. UU., Protects them from diabetes, weight problems, tooth decay syndrome and sudden infant death. The human milk proteins are better used by the body than cow’s milk, even though the latter contains more quantity.
Also, consumption contain antibodies to prevent infection and strengthen the immune system of infants. Although the benefits of this practice have been widely disseminated, globally less than 40% of infants are exclusively breastfed in the first six months.
The figure in Costa Rica in 2010 was 53%, according to the National Household Survey 2010. Several scientific studies show that nursing practice also provides benefits to mothers.
The suction of the baby immediately after delivery releases the hormone oxytocin in the mother, which causes uterine contractions that help prevent postpartum hemorrhage and soon returning the uterus to its normal state.
There is also a lower risk of anemia after pregnancy to breastfeeding, as it delays your period for several months.
In the long term, reduces the risk of several cancers, including breast and ovarian cancer, and the possibility of osteoporosis. Long-term benefits. ‘s study at Brown University also found that the positive effects of breastfeeding are enhanced when breastfeeding is longer or extended.
The children in the study who were breastfed for more than a year showed a greater brain growth than those with shorter periods of breastfeeding. This difference was more pronounced in areas of the brain related to motor skills.
According to the study coordinator, Sean Deoni, this research adds more data to the large amount of positive feedback on the effects of breastfeeding. “I think you could argue that, together with previous evidence, breastfeeding is quite beneficial,” concludes Deoni.
Asked about the issue, Sonia Chaves, excoordinadora of National Breastfeeding Network said: “95% of women are able to breastfeed. 5% are not because they suffer from hormonal problems, do not have mammary glands or a rare condition called Sheehan’s syndrome. Beyond that, any woman can “.
