Breast Milk and the Truth Behind Alpha-Lactalbumin

Parents should expect their child proper growth and development as they age, however, brain development and intelligence depend on various factors, from heredity, nurture and essential nutrient from food intake, including Alpha-Lactalbumin, high quality protein found in mammal breast milk.

Alpha-Lactalbumin is high quality protein with the sequence of amino acid composition such as tryptophan and Cysteine found in human breast milk. It acts as a precursor of its metabolites and also a component of the lactase synthetase complex. Thus, “human breast milk” which is enriched in Alpha-Lactalbumin is major source of protein that plays important role in neurotransmitter function.

The Miracle of “Breast Milk”

Human breast milk composed of essential nutrient for child’s brain development and intelligence, and also be a source of high quality protein, “Alpha-Lactalbumin”, that plays important role in neurotransmitter function.

Infants with breastfeeding show a good sign of their nervous system. The breastfeeding period also effects to child’s intelligence. Research says infant with breastfeeding is more intelligent, have better cognitive, memory skill and sleeping ability than non-breastfeeding infant

Children should be breast fed as breast milk is enriched in essential nutrient including Alpha-Lactalbumin, high quality protein which is easy to digest. Tryptophan, a precursor of its metabolites “Serotonin” which considered to be a contributor of sleeping ability can help better and longer sleep also.

Not only the child should get essential nutrient for healthy growth, a good sleep habit also effects to brain development. Child’s sleep is quite different from adults’ as it helps their brain consolidate everything happened in daytime to their memory and nervous system is potentially developed for better cognitive skill.

Breastfeeding before bedtime is the key strategy for child’s sleep and brain refresher which leads to their effective learning skill. Breast milk is enriched in nutrient such as vitamin, mineral and essential nutrient like carbohydrate, protein including “Alpha-Lactalbumin”, whey protein which composed of essential amino acid “Tryptophan” and its metabolite “Serotonin”, a contributor of sleeping ability.

Nurture and nutrition from food intake are also considered to be key factor for child’s brain development which all parents need to pay attention of. Proper nutrition in daytime will help brain development for cognitive skill and physical strength performs better. Such essential nutrient like DHA, Lutein including Iodine, Iron and Alpha-Lactalbumin play important role in brain development. “Alpha-Lactalbumin” which composed of essential amino acid “Tryptophan”, a contributor of sleeping ability will help child better sleep after breastfeeding.

The relation between breastfeeding and child’s brain development is a new aspect of science to help support the idea of 1,000 days in an early life and a new definition of child’s health care as many studies show that the longer for breastfeeding, the better child’s IQ and cognitive skill development in later life.

Horwood LJ et al study shows the association between duration of breast milk feeding and cognitive ability at 7-8 years. Increasing duration of breast milk feeding was associated with increases in both verbal IQ and performance IQ: children breast fed for eight months or longer had mean verbal IQ scores that were 10.2 points higher and performance IQ scores higher than children who did not receive breast milk.
