Abstract

Apparently healthy Indian lactovegetarians have significantly lower serum levels and urinary excretion of vitamin B12 as compared to non-vegetarians. The low levels of serum vitamin B12 in lactovegetarians are not due to defective absorption but to low dietary intake of this vitamin. Inspite of considerably low serum vitamin B12 values, the lactovegetarians have no apparent signs or symptoms of vitamin B12 deficiency and their response to injected cyanocobalamin mixed with tracer radioactive B12, as judged by urinary excretion pattern and liver uptake, was similar to that observed in nonvegetarians.

摘要

与非素食者相比，表面健康的印度乳类素食者血清中维生素B12水平和尿中维生素B12排泄量明显更低。乳类素食者血清维生素B12水平低并非由于吸收缺陷，而是由于该维生素的膳食摄入量低。尽管血清维生素B12值相当低，但乳类素食者没有明显的维生素B12缺乏体征或症状，并且根据尿排泄模式和肝脏摄取情况判断，他们对注射的与示踪放射性B12混合的氰钴胺的反应与非素食者相似。
