[Benton] explores the evolutionary basis behind children's food choices—for example, babies and toddlers have an innate preference for sweet and salty flavours and avoid bitter and sour tastes. This is explained as reflecting an evolutionary background where sweetness predicts a source of energy, whereas bitterness predicts toxicity/poison.
He also discusses the evolutionary mechanisms that might explain why children avoid new foods (termed neophobia), particularly in toddlers. In our evolutionary past, avoiding new foods had survival value if it discouraged eating items that might have been poisonous, particularly at the stage when a child was beginning to walk. Benton stresses that "Parents need to understand that neophobia is normal."
