Dietary vitamin A intakes of chinese children with adequate liver stores as assessed by the retinol isotope dilution technique

Table 4 Dietary intakes of vitamin A of the children with adequate liver vitamin A reserve¹

	Age
	4 ~ 6 y (n = 20)	7 ~ 9 y (n = 35)	Total (n = 55)
Vitamin A (µg RE /d)	476.9 ± 196.7	529.1 ± 87.2	507.4 ± 137.3
Vitamin A (µg RAE /d)	377.7 ± 166.2	464.0 ± 81.1	442.3 ± 123.4
β-carotene (µg/d)	1053.8 ± 518.2	782.7 ± 224.6	879.5 ± 376.9
vitamin A from plant foods (RE %)	36.8	24.7	28.9
vitamin A from plant foods (RAE%)	23.3	14.0	17.0

¹ Data are presented as mean ± SD. (all variables were normal distribution when one-sample kolmogorov-smirnov test was used to test).The liver vitamin A levels of ≥ 0.07µmol/g and < 1.05 µmol/g liver are considered as adequate vitamin A reserve. Two children with lower (< 0.07umol/g) and one with higher (> 1.05umol/g) liver vitamin A reserve were excluded, two samples were unresponsive in the detection of enrichment of labeled vitamin A, so n = 55
