Tea consumption in newborns: between cultural practice and health risks

The consumption of teas and herbal infusions by newborns and infants younger than six months remains a widespread cultural practice in Brazil, despite national and international recommendations advocating exclusive breastfeeding during this period. This study presents an integrative literature review published between 2014 and 2023, aiming to synthesize scientific evidence regarding the prevalence, determinants, and health risks associated with tea consumption in early infancy. Searches were conducted in PubMed/MEDLINE, SciELO, LILACS, and Scopus, following the methodological framework proposed by Whittemore and Knafl. Findings indicate a high prevalence of early introduction of teas, particularly in the North and Northeast regions, often motivated by traditional beliefs passed down through family figures such as grandmothers and traditional birth attendants. Key determinants include low maternal education, inadequate prenatal and postnatal care, and strong influence from intergenerational support networks. Documented risks encompass impaired iron absorption, microbiological contamination, allergic reactions, exposure to plant toxins, and negative effects on exclusive breastfeeding, ultimately contributing to early weaning. The critical appraisal of the studies reveals methodological limitations, including scarcity of longitudinal designs and heterogeneity in defining “tea consumption.” The persistence of this practice highlights the complex interaction between cultural norms and scientific recommendations. The findings underscore the need for culturally sensitive health-education strategies that acknowledge traditional knowledge while promoting evidence-based practices to safeguard infant health.
