Contribution of food sources to the vitamin B-12 status of South Indian children from a birth cohort recruited in the city of Mysore

摘要

Objective: There is evidence that subclinical vitamin B-12 (B-12) deficiency is common in India. Vegetarianism is prevalent and therefore meat consumption is low. Our objective was to explore the contribution of B-12-source foods and maternal B-12 status during pregnancy to plasma B-12 concentrations.
