Olfactory responsiveness was assessed in 24 neonates born to mothers who had or had not consumed anise flavour during pregnancy. Both groups of infants were followed-up for behavioural markers of attraction and aversion when exposed to anise odour and a control odour immediately after birth and on day 4. Infants born to anise-consuming mothers evinced a stable preference for anise odour over this period, whereas those born to anise non-consuming mothers displayed aversion or neutral responses. This study provides the first clear evidence that through their diet human mothers influence the hedonic polarity of their neonates' initial olfactory responses. The findings have potential implications for the early mother-to-infant transmission of chemosensory information relative to food and addictive products.
对24名母亲在孕期食用或未食用茴芹味食物的新生儿进行了嗅觉反应评估。两组婴儿在出生后即刻及出生后第4天接触茴芹气味和对照气味时，均对吸引和厌恶的行为指标进行了随访。在此期间，母亲食用茴芹的婴儿对茴芹气味表现出稳定的偏好，而母亲未食用茴芹的婴儿则表现出厌恶或中性反应。这项研究首次提供了明确的证据，即人类母亲通过饮食影响新生儿最初嗅觉反应的享乐极性。这些发现对于早期母婴之间关于食物和成瘾性产品的化学感应信息传递具有潜在意义。
