THE NUTRITIONAL LEDGER
The dark adaptation test is related to a vitamin A deficiency. In
this study it is found that dark adaptation, or ability to adjust one's
eyesight to abrupt changes from bright light to semi-darkness, is
dietary matter related to vitamin A intake and perhaps also to other
nutrients as well.
In a more recent study of 1362 metropolitan children, also conducted as a
part of the Pennsylvania Mass Nutrition Studies (Ellen F Richards
Institute Research Series Number 2), the earlier findings have been
confirmed. Of these children, representing a wide economic range,
46.43 per cent., only, were receiving the amount of
energy-containing foods recommended by the Food and Nutrition Board,
National Research Council, for their respective ages and sexes;
41.07 per cent. were receiving the recommended amounts of
protein;
26.79 per cent., the recommended amounts of calcium;
