Nearly 1 in 5 (18%) infants in the United States is not consuming sufficient iron. A deficiency of iron during early life may be associated with long-term neurodevelopmental consequence(s). The 2020-2025 Dietary Guidelines for Americans (DGA) are the first DGA to address recommendations for children under 2 y of age. The 2020 Dietary Guidelines Advisory Committee scientific report includes food-group combinations emphasizing iron-rich foods for 6-12-mo-old infants, but these examples did not meet criteria to establish DGA recommended dietary patterns; consequently, iron-rich dietary patterns for ages 6-12 mo are not provided in the 2020-2025 DGA. The 2020-2025 DGA encourage iron-rich foods by 6 mo of age while emphasizing the importance "particularly for infants fed human milk." Early feeding transitions are dynamic and milk feeding groups are rarely static or exclusive such that emphasizing milk feeding groups may become confusing. Risk-to-benefit favors iron-rich complementary feeding for all infants.
美国近五分之一(18%)的婴儿铁摄入不足。生命早期缺铁可能会导致长期的神经发育后果。《2020 - 2025年美国膳食指南》(DGA)是首个涉及2岁以下儿童建议的DGA。《2020年膳食指南咨询委员会科学报告》列出了针对6至12月龄婴儿的富含铁的食物组合示例,但这些示例未达到确立DGA推荐饮食模式的标准;因此,《2020 - 2025年DGA》未提供6至12月龄的富含铁的饮食模式。《2020 - 2025年DGA》鼓励在6月龄时摄入富含铁的食物,同时强调“尤其对于母乳喂养的婴儿”的重要性。早期喂养过渡是动态的,奶类喂养群体很少是固定或单一的,因此强调奶类喂养群体可能会造成混淆。权衡风险与益处后,建议所有婴儿进行富含铁的辅食喂养。
