FIGURE 3.

Preformed retinol and provitamin A intakes in different female age groups within the UK [based on data from (150)]. Proportions of women of different ages in the UK with retinol (A,B) and provitamin A (C,D) intakes from food sources and supplements (A,C) or from food sources alone (B,D) below the RNI or LRNI. The RNI for retinol is 600 μg/d and for LRNI it is 250 μg/d. Provitamin A intake is the sum of β-carotene and one-half the amount of α-carotene and β-cryoptoxanthin consumed. Data are from (150).
