This
might be because carotenoids are not stored in the liver like retinol,
but are deposited throughout the body in fat cells, adrenal
glands and other fatty tissues in addition to their absorption and
conversion rates. However, when only pre-formed vitamin A was
considered, food sources contribute 58.3% of the RNI, which might
lead to deficiency when milk intake is compromised or reduced
after the first year of life. Furthermore, when the carotenoid
content is removed from the standardised menu, the total daily
intake was reduced to 600 lg RE, which is below the UL but still
higher than the RNI. NDNS data indicate that intakes are above
the RNI
