Vitamin A is a micronutrient essential in vision, reproduction, immune function, and cellular differentiation. ProvitaminA carotenoids are plant sources of vitamin A. The isotopic distribution of 13C and 12C in humans is determined by what foods are consumed. C3 plants, i.e., green vegetables, carrots, and pumpkins, have lower 13C:12C than C4 staple crops, i.e., maize, sorghum, and millet. Vitamin A foods from corn-fed animals will reflect the13C:12C feed that the animals eat. The serum retinol13C:12C was previously evaluated as a biomarker for vegetable intake. The retinol13C:12C decreased in humans who increased their.. View More»
