酒精（Alcohol）是強效致畸胎物質（Teratogen），會通過胎盤進入胎兒循環，導致胎兒酒精症候群（Fetal Alcohol Syndrome），引起生長遲緩、智力障礙與面部畸形。目前醫學共識認為酒精無安全閾值，孕婦應完全戒除。咖啡因每日少量（約 200mg 以下）通常視為安全，但酒精則必須絕對避免。
Alcohol is a potent teratogen that crosses the placenta into fetal circulation and can cause fetal alcohol syndrome, resulting in growth retardation, intellectual disability, and facial deformities. The current medical consensus is that there is no safe threshold for alcohol exposure during pregnancy, and pregnant women must abstain completely. Small amounts of daily caffeine (about 200 mg or less) are generally considered safe, but alcohol must be absolutely avoided.
