Aim: To assess the sources of vitamin A and D in the diets of 18 & 43 month old children in comparison to energy intake in core & non-core foods. To provide evidence for dietary recommendations with regard to Vitamin A & D intakes.

Hypothesis: Core foods will supply more of the nutrients than non-core foods but less of the energy.

Dietary Vitamin D levels will be related to Vitamin D status as measured in blood samples collected at 43 months (This will only be done if blood levels of Vitamin D are already available or we can raise separate funds).

The quality of the diet with respect to Vitamins A and D will be related to socioeconomic postion and family make up.

Variables required: Dietary diary data for the children in focus subsample at age 18 & 43 months. Antropometric measurement for these children at both ages and blood levels of Vitamin D if available.
