The Scientific Integrity of Modern Infant Formula

Few products carry as much hope—and scrutiny—as infant formula. Promising to nourish growing babies, many modern formulas now advertise specialized ingredients said to support brain development, strengthen immunity, and bring infants closer to the benefits of breast milk. But how much of that promise is supported by science? In this episode, we explore the evolution of infant formula, tracing its journey from a basic nutritional substitute to one of the most heavily regulated foods in the world. We examine the research behind popular additives, the influence of marketing on parental decisions, and why experts continue to debate the long-term benefits of many enhanced formulations. The story reveals the delicate balance between scientific innovation and commercial ambition, where the goal of giving every child the best possible start must be guided as much by evidence as by aspiration.https://www.economist.com/science-and-technology/2026/06/19/is-fortified-infant-formula-worth-it
