Por que substitutos do leite humano?

For certain rare genetic diseases such as galactosemia,1 (identified through the early newborn metabolic triagem)2 non-milk-based human milk substitutes are the suggested feeding option.

For galactosemia, because the lactose in human milk and dairy-based formulas cause life-threatening symptoms in newborns, newborns must be given soy-based or elemental formulas, even when parents are still waiting for a confirmation of a diagnosis after an abnormal result from initial newborn screening.

Reasons for infants to require specialized formula instead of human milk:3

  • Infants with classic galactosemia: a special galactose-free formula is needed.
  • Infants with maple syrup urine disease: a special formula free of leucine, isoleucine, and valine is needed.
  • Infants with phenylketonuria: a special phenylalanine-free formula is needed (some breastfeeding is possible, under careful monitoring).

There are medical reasons pertaining to the health of the lactating parent to not breastfeed as well.4
