This study investigates the prolonged use of privately purchased pasteurized donor milk (PDM) in healthy newborns, which can undermine breastfeeding promotion efforts and waste resources of PDM for more vulnerable newborns.

Breastfeeding is one of the most powerful interventions to save infant lives globally.

This paper provides an evolutionary perspective on why modern complementary food diets are often inadequate, asserting that inadequate diets and nutritional deficiencies have likely been a part of the human condition since the agricultural revolution.
