The complexity of producing and interpreting dietary vitamin A statistics
Journal of Food Composition and Analysis(2021)
Abstract
•38 of 90 food composition tables reviewed report total vitamin A values poorly.•Only 9 tables provide total vitamin A values expressed in both RE and RAE.•25 tables provide enough information to calculate total vitamin A in RE and RAE.•Consensus on the conversion of pro-vitamin A carotenoids to retinol is needed.•Vitamin A adequacy ratios vary with the unit of intake and source of requirements.
