The nutritive Status and intake of nutrients of farmers residing in Narita and Oyama Villages in the vicinity of Nihonmatsu City, Fukushima Prefecture was successively investigated twice, on September 1959 and February 1960, a number of 114 farmers serving as subjects. The subjects were instructed to take nutrients and drugs for a period of half a year between Sep. '59 and Feb., 60 and effectiveness of the above nutrients and drugs was investigated.
It is reported that in Japan there are presumably 11.5 million households of widows with children who are living on the very low-income or live on government subsidy. To survey about their nutritional status is of an important significance for welfare as well as for their better nutrition. This report is about the results of a nutrition survey on mothers and children of such low-income in a certain institution in Tokyo. 1) The nutrient intake: On an average, their nutrient intakes are poor, especially protein is inferior to that of all-Japan average both in quantity and in quality. The ratio of animal protein to total protein is low, and protein score is 72. Of all the nutrients calculated, calcium and vitamins are less than one half of the allowances. Since most of mothers are working out, they have little time for cooking, in their daily recipes cooked-foods sold at the shop are very often seen. Consequently the animal foods, especially meat, egg and milk are seldom used, and vegetables and legumes are also not enough ingested. 2) Body measurements: Generally speaking, the mothers belong to the “lean type”, and the growth of school children is rather inferior. Especially their body circumferences (upper arm and chest) are of low values. 3) Biochemical observations: Blood gravity and hemoglobin values are averagely low, and about 60% of the mother and 50% of the middle school pupils are under the normal range. The concentration of vitamins in blood and in urine (A, C, B1, B2, and N′-methyl-nicotinamide) are also remarkably low, and more than half of the mothers and about 30% of the boys and girls are in vitamin low level and deficiency. 4) Clinical observations: Beriberi-like symptoms are remarkable, more than half of the mothers having such symptom, and about 73% are of malnutritional disease. 5) As to their economical status, it was very difficult to obtain the exact information, but evaluating their expenditure on foods from the market price, it was 103.9 yen per adult per day. It is lower than all-Japan average. So-called Engel's coefficient was as-high as 88%, though it was evaluated from the presumed incomes.
Some kinds of water soluble fractions of soy bean oil meal were given as protein sources for the growth experiment of rats, and the results were compared with the data of soy bean oil meal fed rats. In experiment I, the results showed that both water soluble fraction of soy bean oil meal and the water soluble substance of the heated meal had less effect on the growth of the rats. In experiment II, it was demonstrated that weak heating of the extracted gels of soy bean oil meal gave a better growth in comparison of the growth of the unheated fraction fortified with DL-tryptphan. The residual fraction of the water extracted meal was most effective on the growth of rats, whereas the mixture of unheated water soluble fraction and the residual substances gave less effect on the growth of rats. The growth was markedly improved by enriching methionin to the unheated water soluble fraction of the meal.
Dietary protein quality and quantity are characteristically reflected in the ratio of allantoin to urea. If the value of allantoin (A)/urea (U) ratio multiplied by the protein intake (Ip), (A/U)×Ip, is adopted considering the protein consumption at that time, this value falls into a certain constant point corresponding to the quality of protein used as a dietary ingredient, independently of varying the protein level or protein intake. In order to obtain more detailed knowledge on these phenomena, the present studies were carried out. When male adult rats of Wistar strain (370g) were fed on the diets incorporated egg albumin, casein, or wheat gluten at the levels of 10 and 25 per cent, (A/U)×Ip values were pursued. It was again found, as the results, that the values of the ratio of allantoin to urea multiplied by protein intake were not affected by dietary protein level or protein level or protein intake. Moreover, even immediately after the level of dietary protein was reduced from 25 to 10 per cent, these regularities were maintained.
In this report, total riboflavin content and three different types of riboflavin contained in fresh eggs were measured. Riboflavin determination was carried out by the microriboflavin assay method of K. Yagi. Fish eggs, as fresh and mature as possible were collected from the fish market as Tsukiji in Tokyo. The results are shown in Table 1-3. The total riboflavin content of fresh eggs ranged from approximately 600γ% to 700γ% in the average. It was found that the percentages of three different types of riboflavin contained in fish eggs show the wide variations, but the great parts of riboflavin in fish eggs exist in the form of nucleotides, namely flavin adenine dinucleotide and flavin mononucleotide.
