Records of the dietary intake of 52 preschool vegetarian children seen from 1974 to 1976 revealed that macrobiotic vegetarian diets provided amounts of vitamin D, calcium, and phosphorus that were marginal as well as less than the amounts provided by other vegetarian diets. Vitamin D supplements were rarely given. Two subjects had roentgenographic evidence of rickets. The medical histories of 32 children on macrobiotic diets who were examined in 1977 more frequently included prior physical and roentgenographic findings indicative of rickets, whereas those of 17 other vegetarian children did not. Children in the former group were more likely to have elevated levels of serum alkaline phosphatase. Two additional cases of rickets in children consuming a macrobiotic diet confirmed by roentgenograms were brought to our attention during the study.
1974年至1976年间对52名学龄前素食儿童饮食摄入情况的记录显示，生机饮食提供的维生素D、钙和磷含量处于边缘水平，且低于其他素食饮食所提供的量。很少给儿童补充维生素D。两名受试者有佝偻病的X线证据。1977年接受检查的32名采用生机饮食的儿童的病史中，更频繁地出现先前提示佝偻病的体格检查和X线检查结果，而其他17名素食儿童则没有。前一组儿童血清碱性磷酸酶水平更有可能升高。在研究期间，又有两名食用生机饮食的儿童经X线检查确诊为佝偻病的病例引起了我们的注意。
