3 DRIs Definition & Indexes  Estimated average requirement (EAR)  Recommended nutrient intakes (RNI)  Adequate intake (AI)  Tolerable upper intake level (UL)

 NOAEL(No￾observed-adverse￾effect level) 无毒副反应水平  LOAEL(Lowest￾observed-adverse￾effect level) 最低毒副反应水平

 NOAEL(No￾observed-adverse￾effect level) 无毒副反应水平  LOAEL(Lowest￾observed-adverse￾effect level) 最低毒副反应水平

EAR RNI UL 1.0 毒副作用 十 0.5 0 摄入水平 图1-1 营养素摄入不足和过多的危险性图解

4 UL/NOAEL/LOAEL Background 1 满足需要不仅指预防营养素缺乏，而且纳入了减少 某些疾病风险的概念，营养素需要量趋于偏高。 2 通过研究加强了对营养素毒副反应的认识，营养素 的过量或相互作用均可增加潜在的毒副反应。 3 保健食品或膳食补充剂所用的强化剂常为化学品， 比食品所含的营养素易于产生毒副作用。 4 特殊人群，如儿童、老人、孕妇对营养素毒副反应 的敏感性增加
