🚨🚨 Is it true? Breast milk isn't that much better than formula? Recently, podcaster Jay Shetty and economist Emily Oster discussed this topic.
Some where shocked to hear it said, "breast milk has benefits but maybe not as much as we hear."
But what does SCIENCE say?
Science says breast milk is the biologically normal food for human infants. We know that:
✨ Breastmilk contains antibodies, enzymes, and immune factors not found in formula (AAP, WHO)
✨ It’s associated with lower rates of infections, SIDS, and some chronic conditions
✨ It adapts over time to meet a baby’s changing needs
✨️ It reduces the risk of certain cancers, diabetes, and some cardiovascular disease in women who breastfeed
Or, if we approach breast milk as the human baseline, that would mean:
✨️Formula feeding lacks antibodies, enzymes, and immune factors
✨️Formula feeding is associated with increased risk of infections, SIDS, and some chronic conditions
✨️Formula lacks the ability to change over time with baby's needs
✨️Not breastfeeding increases the risk of some cancers, cardiovascular disease and metabolic disorders in women.
So, what were Shetty and Oster discussing?
👉 Many long-term outcome differences (like IQ or growth) are influenced by factors like socioeconomic status, access to care, and parental support
Meaning, yes. breast milk is our biological norm and thus ideal for nearly all human infants. But population level statistics aren't the same as individual outcomes.
Many things influence health, growth, and development. Parents should use this info to make informed choices and know that breastfeeding is worth the hard work.
However, they can also know that if they need to or simply choose to use formula, this does not always mean bad outcomes for their kids.
Info about breast milk is important for public health. It informs hospital and public health policy, encourages adequate parental leave and access to lactation support.
Info is never meant to make parents feel bad. Formula provides adequate nutrition and calories to help infants grow and develop.
