Since it has been suggested that mayonnaise has a lowering potential on the serum cholesterol level on young rats fed ad. lib. and also on human adults ingesting 100gm/day of mayonnaise, we attempted to evaluate the effect of voluntary intake of mayonnaise instead of a definite intake of 100mg/day on the serum cholesterol level. After the subjects were placed for two weeks on the basal diet, nineteen men and women took as much as possible mayonnaise besides the basal diet for two weeks according to their individual taste. The mayonnaise intake in gm/day ranged from 3.1 to 50.6 with a mean of 39.7±17.0. The serum cholesterol values in mg/dl in the basal diet period and the mayonnaise period were 202.0±22.3 and 183.0±30.9, respectively. The difference between the two values was significant at the 5% level. Though correlations for the amount of mayonnaise consumed either with the cholesterol level when subjects were fed mayonnaise or with the gradient in the serum cholesterol change were not significant, a mayonnaise intake over 40gm/day or over 11% of the total calories resulted in more or less lower serum cholesterol levels in those fed mayonnaise than those receiving the basal diet.
In the present paper, the investigation on the relationship of urinary hydroxyproline (HOP) excretion to growth and nutritional status has been carried out in Japanese school children, consisting of 518 boys and girls aged 9 to 15 years in the city and farming regions, and 33 boys aged 14-15 years in mountain villages. The determination of urinary HOP was made by the method of Woessner. Results: (1) A peak of HOP excretion by age was seen at 12 years of age for the boys and at 11 years of age for the girls in urban children, and those at 1.3 years of age for boys and 11 years of age for girls in rural children, respectively, and afterwards the HOP excretion fell rapidly in each group of children (Fig. 1). The level of HOP excretion of urban children was higher till the age of 13 years in boys and up to the age of 11 years in girls as compared with rural children, and afterwards rural boys and girls maintained a slight higher level of HOP excretion than that of urban children (Fig. 2). HOP excretion of boys aged 14-15 years in a mountain village was higher significantly as compared with urban and rural boys (Fig. 3). These trends of the excretion of HOP by age, sex and regional groups well agreed with the curve of growth rate of Japanese children. The correlationship between HOP excretion and serum alkaline phosphatase was seen with the correlation coefficients of 0.66-0.77 in 14-15 years old children (Table 2). In the children aged of 9-10 years, significant correlations were seen between HOP/creatinine ratio and N/creatinine and UN/creatinine (Table 3). The correlations of HOP/24h. to HOP/cr.×body-weight, HOP/cr.×body-height and HOP/cr. ratio showed the coefficients of 0.81, 0.75 and 0.70 respectively (Table 4). Discussion was made about that indices of HOP/cr.×wt. or HOP/cr.×ht. based on the random urine specimen could be used instead of HOP/24h., however the HOP/cr. ratio was useful for the evaluation of the growth activity.
This paper reports on the state of nutrition of people living in Kitakyushu City during the last eight years and is related to the yearly transition of the intake of different foods. 1) It was in 1969 that the pattern-similarity was most similar to the Japanese standard, followed by 1971. The most different pattern from the standard was that of 1965, and 1964. It is desirable that a certain pattern similar to the standard should be shown with the lapse of years. 2) It was in 1969 that the difference between the patterns was closest to the standard, and the difference in 1971 was close to the standard following 1969. Distinct differences to the standard was shown in 1965, followed by 1964. Along with the lapse of the years it showed a tendency to approach the standard, but was still far closer than the standard of each year. 3) Ranking the subtrahend similarity index against the standard intake, it was shown that the first element that caused the pattern similarity decrease each year was dairy-products, next soy beans and the soy bean products. It should be recognized that these food-items were proteins of high quality. Conversely each year the factor that caused the pattern to resemble the standard was corn and other vegetables. Finally, the pattern similarity index shows a tendency to be higher since about 1967. Therefore, the ideal food-intake pattern resembling the standard should be forecated in the future.
