about 26 per cent of the total calories, pork normally about 16 per cent, dairy
products 15 per cent, and sugar 7 per cent. Then came corn, beef, the vegetable
oils, potatoes, poultry and eggs, other vegetables, and apples in decreasing
table oils potatoes poultry and eggs other vegetables and apples in decreasing
much as 1 per cent of the total calories. The changes in 1917-18 showed the
result of the efforts of the U. S. Food Administration in that the articles on
which conservation was most strongly urged (wheat, beef, mutton, pork, and
sugar) showed a decidedly lower consumption and rye, other cereals, nuts,
and vegetables an increased consumption.
The average per capita per diem consumption as calculated from the total
population, and the age-intake values was for the whole period as follows:
Protein 120, fat 169, and carbohydrate 541 gm. with a total energy value of
4,288 calories. It is pointed out that this represents the gross consumption,
and that by applying the estimated percentage deductions for edible wastage,
the corresponding figures would be 114, 127, 433, and 3,424, respectively. These
figures are in general agreement with the results of a number of American
dietary studies which have been compiled for purposes of comparison, the
corresponding figures being 95, 113, 447, and 3,185, respectively.
In conclusion it is emphasized that in calculating the food requirements of
a nation "a considerable excess over any agreed-upon minimum physiological
requirements must always be allowed, because there will inevitably be, in fact,
a margin between actual gross consumption and net physiological ingestion or
utilization." The gradually rising prices during the period since 1911 are
thought to have brought about a slight narrowing of the margin between gross
and net consumption.
As an appendix, a table is given indicating the consumption of nutrients in
the form of feeds and fodder by domestic animals as determined by the same
statistical plan followed in the case of human foods.
The modern science of food values, H. P. ARMSBY (Yale Rev., 9 (1920), No.
2, pp. 330-345).-In this article the author takes stock of the contribution of
modern science to our knowledge of food values and considers the fundamental
importance of an adequate food supply and of rational measures of
insuring it.
The days when food was so abundant in the United States that it could be
used almost as one pleased, he points out, are gone never to return. " Even
though we may hope to make an end of war we can not hope to escape from
the world's continually growing demand for food. The density of population
that can be supported is practically limited by the amount of solar energy
which the farmer can recover in food products and the efficiency with which
these products can be utilized as fuel for the human body. Any rational effort
to extend this limit must include as its prime requirements not only a systematic
development of agricultural production, such as is now being effected
by national and State agencies, but also an equally systematic attention to the
conservation and most efficient utilization of the products of the farm. The
two are but different aspects of the one great problem of national nutrition.
Without reflecting upon any existing agencies, surely it is high time that,
along with military, naval, transportation, and manufacturing programs, this
fundamental problem vital to our national existence and welfare, should be
taken up in its entirety by some national agency charged with the investigation
of the scientific and economic aspects of food supply and utilization, and
with the diffusion of the knowledge, thus gained, among the people."
Further studies of qualitatively insufficient foods, A. AUER (Biochem.
Ztsehr., 93 (1919), No. 1-2, pp. 1-15, figs. 2).-This is a continuation of the
studies of Oseki previously noted (E. S. R., 32, p. 561). White mice were fed
