The etiology of micronutrient deficiencies in infancy is well described. The deficiencies are caused by one of the following four scenarios: (a) low initial stores of micronutrients from micronutrient deficiency during gestation, premature birth or low birthweight; (b) rapid postnatal growth; (c) ingestion of foods with low concentration of micronutrients, and (d) gastrointestinal pathology resulting in the malabsorption of nutrients, including micronutrients. Understanding the cause of the deficiencies is essential in planning interventions to either prevent or treat them. This chapter will focus on the dietary causes of micronutrient deficiencies and recent strategies to correct them.
婴儿期微量营养素缺乏的病因已有详尽描述。这些缺乏症由以下四种情况之一引起：(a) 孕期、早产或低出生体重导致的微量营养素初始储备低；(b) 出生后快速生长；(c) 摄入微量营养素浓度低的食物；以及 (d) 胃肠道病变导致包括微量营养素在内的营养物质吸收不良。了解这些缺乏症的病因对于规划预防或治疗的干预措施至关重要。本章将重点关注微量营养素缺乏的饮食原因以及纠正这些缺乏症的最新策略。
