Why breastmilk?

Reading Time: 5 minutes

Human milk1 is for human babies.2

In ‘The 10 facts on breastfeeding,’ the WHO states that a lack of exclusive breastfeeding during the first six months of life contributes to over a million avoidable child deaths each year. As the ‘10 Steps to Successful Breastfeeding’ states: “everyone has the right to information about the benefit of breastfeeding and the risks of artificial feeding. Governments have a responsibility to provide this information. Communities as well as media and other channels of communication can play a key role in promoting breastfeeding.”

In ‘Why it is important to share and act on this information,’ Facts for Life states: “Breastfeeding is the natural and recommended way of feeding all infants, even when artificial feeding is affordable, clean water is available, and good hygienic conditions for preparing and feeding infant formula exist.”

In ‘The Risks of Not Breastfeeding for Mothers and Infants’, Dr. Alison Stuebe writes: “Given the compelling evidence for differences in health outcomes, breastfeeding should be acknowledged as the biologic norm for infant feeding.”

In ‘Breastfeeding and the Risk of Postneonatal Death in the United States,’ the authors conclude: “Breastfeeding is associated with a reduction in risk for postneonatal death. This large data set allowed robust estimates and control of confounding [external variables that can obscure or exaggerate an outcome –ed.], but the effects of breast milk and breastfeeding cannot be separated completely from other characteristics of the mother and child. Assuming causality, however, promoting breastfeeding has the potential to save or delay 720 postneonatal deaths in the United States each year.”

The title of this Lamaze position paper reads ‘Breastfeeding is priceless: No Substitute for Human Milk.’ Lamaze goes on to say that “the World Health Organization (WHO), health care associations, and government health agencies affirm the scientific evidence of the clear superiority of human milk and of the hazards of artificial milk products.”

Protective factors of breastmilk
Human milk provides protection against many infectious agents through repeated exposure and the total antimicrobial protection provided by human milk appears to be far more than can be explained by examining protective factors individually.

In Necrotizing Enterocolitis: Protective Role of Breastmilk,’ the authors write that “Breastmilk feedings are associated with a decrease in NEC [Necrotizing Enterocolitis –ed.] in premature infants” and they attribute this to the unique immunologic properties of breastmilk.

This study on the ‘Storage of human milk and the influence of procedures on immunological components of human milk’ shows that breastmilk “can be stored for 8 hours at room temperature (25 degrees C), for three days in the fridge (4 degrees C) and for up to a year in the freezer (-20 degrees C) without any increase in the levels of pathogens (harmful bacteria) it contains”.

In ‘Antimicrobial Activity of Breastmilk Against Common Pediatric Pathogens,’ the authors state: “It can be said that in any part of the world, no single pediatric measure has such widespread and dramatic potential for child health as a return to breastfeeding.”

In this previous but valuable study on the effect of routine screening of raw breastmilk and donor milk for premature babies, the authors discuss that while the data clearly document that premature infants fed raw expressed human milk are frequently exposed to large numbers of bacteria, no adverse events directly related to consuming this milk were documented.

According to Richard J. Schanler, et al., in this study, “advantages to an exclusive diet of MM [mother’s milk] were observed in terms of fewer infection-related events and shorter hospital stays.”

Physical benefits of breastfeeding3
Other important benefits of breastfeeding include proper jaw and facial development which reduces both ear infections and bite issues, by preventing malocclusion.4 The skin to skin contact that breastfeeding provides helps babies acquire the beneficial bacteria that protects them from diseases and builds their immune system.5 Skin to skin contact also provides relaxation for both parent/caretaker and child due to the effects of oxytocin. Long term benefits are laid out in this WHO publication. Breastfeeding also has its economical benefits.

Another important factor of breastmilk is that during breastfeeding, baby’s saliva reacts with the breastmilk to produce chemically reactive molecules containing oxygen while simultaneously providing growth-promoting nucleotide precursors. In other words, breastmilk produces a combination of stimulatory and inhibitory metabolites that regulate early oral–and hence gut–microbiota when mixed with saliva.6

For additional information on the physical benefits associated with breastfeeding for both parent/caretaker and baby, see Lamaze’s ‘Healthy Birth Practice #6: Keep Mother and Baby Together – It’s Best for Mother, Baby, and Breastfeeding’.

Lastly, this in-depth study by Brian Palmer, DDS, discusses the benefits of breastfeeding and overall health.

Healing properties of breastmilk
In addition to its biological and physiological benefits, breastmilk has also been shown to have some amazing healing properties. More and more research is showing the healing and disease killing properties of breastmilk. Researchers conclude that multipotent stem cells, isolated from human breast milk could potentially be ‘reprogrammed’ to form many types of human tissues. The presence of these cells in human milk suggests that breastmilk could be an alternative source of stem cells for a patient’s own stem cell therapy.

Breastmilk compounds kill warts: “Compound in breast milk has been found to destroy many skin warts, raising hopes it might also prove effective against cervical cancer and other lethal diseases caused by the same virus.” A cancer killing substance, named HAMLET has also been found in breasmtilk.

The importance of the act of breastfeeding
Lastly, the benefits of breastfeeding are more than its product, the milk. They are beyond providing food and drink to one’s child for superior growth and development. There is more to breastfeeding than just the nutritional component of the milk itself. The time spent between a caregiver and a child is also vital to the development of a strong relationship. It provides an opportunity to interact and connect. Therefore, it is no surprise that mothers who breastfeed their children are less likely to abuse their children.

Newborn humans are born in a helpless state and continue their development after birth. The nurturing embraces of breastfeeding mimic the embrace of the womb that the baby experienced in utero. In light of this, the method a caregiver uses to provide donor milk to a baby is thus also very important. Please also see ‘How do I feed the milk to my baby.’

Next: WHO guidelines for exercising feeding options

_______________

  1. In this document EOF utilizes the WHO definition of exclusive breastfeeding which includes milk from another mother (see ‘WHO guidelines for exercising feeding options). In support of exclusive breastfeeding, in circumstances where wet-nursing is not feasible, informed milk sharing can be a viable option for families. Milk sharing can be seen as an extension of wet-nursing, and as a safe alternative for infant feeding and successful exclusive breastfeeding. EOF recognizes the benefits that direct breastfeeding from the breast bestows as well as the value of the milk itself. We may therefore use the words breastfeeding and breastmilk interchangeably. []
  2. Breastfeeding, and especially early breastfeeding, is one of the most critical factors for improving child survival. Breastfeeding also has many benefits other than reducing the risk of child mortality. HIV has created great confusion among health workers about the relative merits of breastfeeding for the mother who is known to be HIV-infected. Tragically this has also resulted in mothers who are known to be HIV uninfected or whose HIV status is unknown, adopting feeding practices that are inappropriate for their circumstances with detrimental effects for their infants. In ‘Guidelines on HIV and infant feeding. 2010. Principles and recommendations for infant feeding in the context of HIV and a summary of evidence’, the research group also noted how infant feeding, even in settings where HIV is not highly prevalent, has been complicated by messaging from the food industry and other groups with the result that parents and caretakers, who have every reason to breastfeed, choose not to do so based on unfounded fears. In these settings, application of the International Code of Marketing of Breast-milk Substitutes and subsequent relevant Health Assembly Resolutions has particular importance. []
  3. When nursing directly from the breast is not possible, feeding with an at-the-breast system mimics as much of the natural mechanisms of nursing as possible and provides the same skin-to-skin contact. Please see ‘How do I feed the milk to my baby?’ for more information. []
