Exclusive breastfeeding is recommended for newborns until at least the sixth month. However, in some cases, the use of infant formulas as breast milk replacement has been used to provide the nutritional needs of infants. For children over six months baby foods can often be incorporated into the diet. Aluminium (Al) could be present in baby foods and it has potential neurotoxic effects when ingested and absorbed by the organism. In this study, we reviewed Al toxicology, total content and bioaccessibility in several baby food products. The study was performed as a systematic review of scientific literature on the databases Scopus, Science Direct, Web of Science, and Academic Google. Aluminium content varied according to distinct types of baby foods (0.92−2860mgkg⁻¹). Different analytical methods used to evaluate Al bioaccessibility, including sample preparation and in vitro conditions to simulate the gastrointestinal digestion, indicated that the Al bioaccessible fraction varied from 0.5–48% in the current literature.
