of iodine. In goitrous regions, where sea-fish are not available,
the provision of extra iodine in the form of iodised salt or in some
other way is recommended.
9. An extended dietary use of the potato is recommended
to replace part of the sugar and highly milled cereals in the ordi¬
nary diet. Potatoes provide extra vitamin C and more readily
available calcium and phosphorus than are present in cereals.
Potatoes also yield more iron and B vitamins than milled cereals.
The above paragraph applies to countries where potatoes are
abundant, but it is of general application, due account being
taken of local resources.
10. Requirements of Other Adults and Children.
In Tables I-VI, some simple schedules have been prepared to
show how a selection of common protective foods will ensure safe
intakes of the necessary protein, minerals and vitamins for a
pregnant and nursing woman and for infants and children of
ages up to 14 years. These are based on investigations made
in the United Kingdom, the United States and Scandinavian
countries, and are put forward to indicate how the dietary prin¬
ciples set forth in this report could be put into practice where these
foods are available. In every locality, it will be necessary to
discover the selection of food materials which is best adapted to
national dietary habits and resources, and at the same time
conforms to the needs of pregnancy, lactation and growth.
No attempt is made to lay down a detailed dietary programme,
or to suggest the wide choice of protective and energy-yielding
foods, whose selection will be influenced by availability, appetite
and economic cost. Attention should, however, be directed to the
value of the lightly milled cereals as a further source of iron and
vitamin Bj, and of butter in preference to other common fats,
because of its rich content of vitamin A.
The protective foods in Table I are arranged to yield approxi¬
mately 1,400 calories without inclusion of cereals, fats or sugar;
