FOOD AND NUTRITION 687
successful efforts so far are based on data from the mid-nineteenth
century. This evidence, though scattered, seems to indicate that nutri-
tion probably improved over time, and so the quantitative studies
would represent the highest levels that nutrition probably reached
during the Tokugawa period. The most ambitious studies are for the
Hida area of Gifu and for the domain of Choshu in western Honshu.
The data for Hida are for 1874 and include the amounts of 168
foodstuffs produced and the amount of food imported and exported
from the area.

By dividing the total amount of food retained in the
region by the total population and by 365 days, one can obtain a rough
estimate of the nutrition available to the "average" person in 1874.
The results of the study of Hida indicate a heavy dependency on rice
and millet, which led to a deficiency of certain essential vitamins and
minerals, notably vitamins A and C, calcium, and iron. The diet was
somewhat lacking in protein and very high in salt content. This evalua-
tion is borne out by the leading causes of death as analyzed from the
records of a local temple. Among the major causes were childbirth
complications (in which calcium deficiencies can play a part), cerebral
hemorrhage (connected to a high salt intake), and epidemics (whose
incidence is worsened by a low level of
nutrition).
The Hida estimates
are for a mountainous area, and the authors of the study admit that
some items known to have been consumed were not included in the
survey, such as sweets, eggs, seaweed, some kinds of mushrooms, and
certainly wild greens that individuals could gather from the mountain-
side.
These would never be included in the
figures
on output, but they
may have contributed to raising somewhat the vitamin content of the
diet. From the data available for Hida, the average daily caloric intake
has been estimated at roughly 1,850 calories.
The Hida estimate can be considered at the same nutritional level as
Choshu's diet, which in the 1840s contained an average per-capita
intake of 1,664 calories from staple foods, including rice, barley,
wheat, millet, buckwheat, soybeans, red beans, and sweet potatoes.

This does not include fish, seaweed, vegetables, fruit, or sweets. Even
though fish and vegetables were a minor part of the diet, they would
almost certainly have added a couple hundred calories per day and
been significant in balancing the diet. By the 1890s, the Japanese in
