This article, which is the second in a series of two articles, discusses available scientific information on the nutritional status of infants and preschool children on alternative diets with regard to calcium, iron, vitamin B12 and D. Some favourable aspects of alternative food habits in such children are also mentioned. Most studies report low intakes of vitamin D and in vegan and macrobiotic children also of calcium and vitamin B12, but it cannot be excluded that some alternative sources of these nutrient may have been missed. Deficiencies have been described for vitamin D and B12 but the evidence is often unconvincing. For example, exposure to sunlight has not been measured in most of the studies on rickets. From the literature available, it would appear that there is a need for longitudinal research on the growth and development of alternatively fed infants and preschool children and for information on the nutrient composition of alternative foods.
本文是两篇系列文章中的第二篇，讨论了关于食用替代饮食的婴幼儿和学龄前儿童在钙、铁、维生素B12和维生素D方面营养状况的现有科学信息。文中还提到了这类儿童替代饮食习惯的一些有利方面。大多数研究报告称，维生素D摄入量较低，纯素食和遵循宏生物饮食的儿童钙和维生素B12摄入量也较低，但不能排除可能遗漏了这些营养素的一些替代来源。已有人描述了维生素D和B12缺乏的情况，但证据往往不足以令人信服。例如，大多数关于佝偻病的研究都未测量日照情况。从现有文献来看，似乎有必要对食用替代饮食的婴幼儿和学龄前儿童的生长发育进行纵向研究，并获取替代食物营养成分的信息。
