Inborn errors of intermediary metabolism (IEiM) are a group of monogenic disorders that affect a metabolic pathway of proteins, carbohidrates, or lipids; when not treated timely, IEiM are associated with high morbidity and mortality. To date, nutritional therapy is the cornerstone of treatment for patients with IEiM, which aims to prevent the accumulation of toxic metabolites by restricting the substrates involved in the affected pathway. Nutritional management in infants includes a metabolic formula free of the nutrients involved in IEiM and breastmilk or infant formula. Because of its amino acid profile, the content of essential fatty acids, and protection against disease, breast milk is an excellent food for patients with IEiM. This literature review on breastfeeding in some IEiM aims to serve as a guide for health care personnel involved in the medical care of these patients. Breastfeeding can be successfully carried out in patients with IEiM as long as there is a close and continuous follow-up, preferably in specialized centers. The nutrition professional and the pediatrician should individualize the recommendations to provide on-demand breastfeeding in conjunction with metabolic formula or quantified breastfeeding to achieve a good clinical evolution in this group of patients.
