The status of thiamin, riboflavin, folate, and vitamins B-6, B-12, C, A, D, and E was investigated in 37 middle-aged and healthy French vegetarians by means of a dietary survey and biochemical studies. Values were compared with those of a group of nonvegetarians. Unsatisfactory intakes of vitamin B-6 were observed: vitamin B-6 intake as a percentage of the French Recommended Dietary Allowances was approximately 66% for vegetarians and approximately 58% for nonvegetarians. Vegetarians had a higher mean intake of thiamin, riboflavin, and vitamins C, A, D, and E than did nonvegetarians. Vegetarians did not have a higher risk rate for a biochemical vitamin deficiency of thiamin, riboflavin, folates, and vitamins B-6, C, A, and E than the nonvegetarians. The percentage of subjects assessed as abnormal by blood vitamin concentrations was higher in vegetarians for vitamin B-12 (serum vitamin B-12) and vitamin D, which indicated a higher risk for a deficiency of vitamins B-12 and D in this group.
通过饮食调查和生化研究，对37名中年健康法国素食者的硫胺素、核黄素、叶酸以及维生素B-6、B-12、C、A、D和E的状况进行了调查。将这些数值与一组非素食者的数值进行了比较。观察到维生素B-6的摄入量不理想：素食者的维生素B-6摄入量占法国推荐膳食摄入量的百分比约为66%，非素食者约为58%。素食者的硫胺素、核黄素以及维生素C、A、D和E的平均摄入量高于非素食者。素食者在硫胺素、核黄素、叶酸以及维生素B-6、C、A和E的生化维生素缺乏风险率方面并不高于非素食者。在素食者中，因血液维生素浓度被评估为异常的受试者百分比在维生素B-12（血清维生素B-12）和维生素D方面更高，这表明该组中维生素B-12和D缺乏的风险更高。
