An attempt was made to discribe the relationships between the dietaly intakes of vitamin A, the Ability of Dark Adaptation and the serum vitamin A levels on 20 healthy college men and women in the domitory, 18 to 19 years of age.
Their nutrient intakes during one month were somewhat bellow those of the average Japanese, particularly, the intakes of animal protein, calcium and vitamin were dificiency to their Recomended Allowance.
The vitamin A intakes of women approximated their Allowance, but those of men roughly one-half as large as their Allowance.
However, the Abilities of Dark Adaptation and vitamin A concentrations in serum of men and women were reasonably geed, and significantly correlation could be detected between their Abilities of Dark Adaptation and vitamin A concentrations in serum.
The use of vitamin compound during 10 days had the geed effects on the Abilities of Dark Adaptation and vitamin A concentrations in serum of men and women.

In rice-cultivating districts farmers and their families are apt to overeat rice, and nutritionally undesirable effect has been generally recognized.
To investigate the effect of the enriched barley a nutritional survey was done on these farmers who were administered the enriched barley in their staple foods, and the following results were founds.
(a) After the administration the cases of the nutritional disease among the farmers were of tendency to decrease, especially among women it was remarkable.
(b) The abnormal systolic pressure patients decreased among men, and diastolic pressure abnormalities decreased both in men and in women.
(c) The degree of fatigue after looding the labor was slighter than that of control group.
(d) The concentratioe of vitamin B₁, as well as the excreted amount in urine in a day were found almost unchangeable.

Though thiamine actions of TA and TAO₂ were investigated with L. fermenti, the effects were not almost recognised about these compounds.
In the case of addition of 50-500 fold TA or TAO₂ to thiamine, they did not afford the effect of bacterial growth. Furthermore even in addition of a large amount of them did not inhibit bacterial growth.
It was found that these compounds had not the antagonistic action against thiamine.

Vitamin B₆ antimetabolic action of TA, TAO₂, AMP which was obtained by hydrolysis TA and TAO₂ and OMP which has been known as an antivitamin B₆ were investigated for Saccharomyces carlsbergensis. OMP showed vitamin B₆ antimetabolic action clearly and a large amount of AMP showed the same action. TA showed the action slightly. This action of TA was assumed to be owing to AMP produced by hydrolysis of TA during the procedure to make TA solution.

This experiment was carried out for purpose of knowing whether alcohol calorie is utilized or not for the muscular work. Four healthy adult men were subjected to the following experimental status, i. e., working after alcohol administration, working at fasting status without alcohol intake and resting status after alcohol administration. In comparison of each result at these experimental status the relation of the muscular work to the alcohol metabolism were discussed.
The muscular work of about 2800 to 4300 kilogrammeter per minute were loaded for 40 minutes by using the bicycle-ergometer, and amounts of individual work were regulated in the same level at the both alcohol intake and fasting status. The load of work at alcohol intake status was made an hour after alcohol was administered. A dose of alcohol was 0.5gm. per kg. body weight. The expired air was collected every 30 minutes and blood and urine sampling was made every one hour up to 5 hours after alcohol administration.
The redults summarized were as follows:
1) The decrease of alcohol concentration in blood during working hour, i. e., the difference between the first and second hour values after alcohol intake, averaged 19.6mg %, which was corrected by subtracting the excess of alcohol excretion in expired air increased by working. This value was much greater than that of 5.5mg% in resting status.
2) “β” factor calculated in lapse of 5 hours after alcohol intake averaged 11.8mg% per hour at working Status, this value was about 36% higher compared with 8.7mg% per hour at resing status. “γ” factor showed no significant difference between both status. “ED” mean value of 4.96gm. per hour at working status was about 40% higher than 3.56gm. per hour at resting status. The increasing rate of “ED” values due to working correlated with intensity or calorie consumption of work (table 1 & 2).
From the above results, it is considered that alcohol metabolism rises with working and alcohol calorie is utilized for the muscular work.

An evaluation of the essential amino acid intake was conducted on the data of Nutritional Survey carried out in the farming village, for three days, in August, 1960. The results obtained were summarized as follows:
1) An average daily intake of protein was 71.6g (Man value), coming up to the revised Japanese standard value and any of the essential amino acid intake almost approximated to the value calculated from the Standard Food Construction of Japanese people.
2) The mean coefficiency of animal protein was low (19.4%) and the rate of the essential amino acid, except Lysine (34.5%) and Methionine (29.5%), taken from animal foods remained very small (about 20%). Except Phenylalanine and Tryptophan the amino acid intake showed a slight upward tendency with the increase of animal protein coefficiency in the case of above 20%, but the variation of their intake was not clear in the case of below 20%.
3) In comparing the intake of the essential amino acid with the Provisional Protein Pattern (FAO), the intake of Methionine, Sulfur containing amino acid and Tryptophan was always low, 81, 73 and 74% respectively, these values being rather less than the ones calculated from the Standard Food Construction of Japanese people.

It is well recognized that the quantity and quality of fats and oils ingested have closely to do with so-called adult disease, such as hypertension or heart disease. Few reports have been found, however, about what kinds of fats or oils are generally consumed among Japanese people.
This survey was done in order to know the above point, and 84 households in Tokyo and its neighborhood cities were selected for the subjects.
The results of the survey showed that fat and oil consumption was 16.4g per head per day on an average, and soybean oil was used most frequently.
Of all the consumed fats and oils, those from the vegetable sources were 67%, and from animal sources 19%, margarine being 14%.
In this survey total fat intake including that from the all foodstuffs ingested was not investigated, but, presuming from the results of the National Nutrition Survey, the ratio of consumed vegetable oil to animal fat may probably be 4:6.
Comparing the above results with the intake of U.S. people, the former is only one quarter of the latter, and an average Japanese intake calculated from the National Survey is almost one tenth of the U. S. intake.
