Abstract: Eating behavior affects human health, and taste preference shapes food intake behaviour. Taste receptors begin to develop during the pregnancy of the mother. The fetus experiences taste and different flavors through amniotic fluid during pregnancy and breast milk after birth. Various taste experiences in the early life may have an impact on taste preference, and then affect future life. This article reviews the possible factors that affect the formation of taste preference among infants and toddlers in order to provide support for cultivating healthy taste preference.
