It is advisable to use vegetable oil in fat-controled diet, because it contains poly-enoic fatty acids. Mayonnaise is an oil-vinegar emulsion made from vinegar and vegetable oil stabilized with egg-yolk. We analysed lipid composition of eight brands of mayonnaise. The ratio of poly-unsaturated fatty acids to saturated fatty acids approximates two or three to one. The average total sterol in above mentioned analyses was 333mg per cent, —cholesterol 67mg per cent, phospholipid 33.6mg per cent. Mayonnaise is a superior foodstuff for the fat-controled diets.
In this report we conducted a same kind of experiment as in the previous report in order to reconfirm the characteristic aspect that amongst the blend oils of rice bran oil and safflower oil the one blended in the ratio 70:30 had a distinctly higher effectiveness for lowering cholesterol level and contrarily the one of the ratio 50:50 had a lower effectiveness than the effectiveness of each original pure oil. In addition a series of blend oils of rice bran oil and sunflower oil instead of safflower oil were also served for the purpose of ascertaining whether the sunflower oil acts similar role or not. A total number of ninety healthy young girls were divided into nine groups and daily took 60g of each oil blended in next ratios for 7 days. R-100: Rice bran oil 100% Sf-100: Safflower oil 100% Sf-15: Rice bran oil 85%, Safflower oil 15% Sf-30: Rice bran oil 70%, Safflower oil 30% Sf-50: Rice bran oil 50%, Safflower oil 50% Sn-100: Sunflower oil 100% Sn-15: Rice bran oil 85%, Sunflower oil 15% Sn-30: Rice bran oil 70%, Sunflower oil 30% Sn-50: Rice bran oil 50%, Sunflower oil 50% As shown in the Figure 1, the effectiveness for lowering cholesterol level was highest in the blend oil Sf-30, showing a value -26% in comparison with the pre-experimental level, that is higher than the value of the rice bran oil -18% or of the safflower oil -14%. On the other hand the effectiveness of Sf-50 was -12%, showing the lowest value and even lower than the values of both original oils. These aspects are the very same as the results obtained in the previous report. Blending oils of sunflower oil with rice bran did not result in the same way, though their fatty acid compositions are fairly alike. The more the content of the sunflower oil in the blending, the more closely resemble to the effectiveness of the sunflower oil as seen in the Figure 2. Accordingly, the characteristic nature seen in the case of blending safflower oil with rice bran may be derived from their unsaponifiable matters.
We investigated about the effects on the farm housewives' nutrition and health of the purchase plan of foodstuff, the presence of home farm produce, the kind of cooks, the economic backing and so on, and consequently obtained material of the nutritional education
We, members of the Rural Medical Association of Kumamoto Prefecture, conducted the health survey of 3600 women in rural areas for the past three years. As the results of this survey, it was found that 75% of women lived in the district of our jurisdiction of Yamaga Public Health Center were suffered from anaemia. For the preventive measure, we conducted further community survey on 1814 women lived in Yamaga area, and following results were obtained. The level of the specific gravity of blood in the age of thirties showed the lowest value and in the age of forties a little higher values were observed. In the age of fifties much better values were observed. In this connection, it may be pointed that the hard works of the houswives in the age of thirties such as nursing domestic work, and farming affected their health conditions. About 30% of housewives showed serum iron deficiency, and most of than ones require any treatments for iron deficiency anaemia. Most of the cases showed the specific gravity of blood level over 1.052, usually take large amount of animal foods, and it is seemed that the nutritional habits in the life has an effect on the course of anaemia. Most of the cases of the specific gravity of blood level below 1.052, showed the farmer syndrome score over 7. These findings indicated that iron deficiency anaemia is widespread in women in the agricultural villages. For prevention of anaemia in these districts, education programs of dietary measures and general sanitation for women should be strengthened.
The study was done in two fields: one was the relation between blood specific gravity and taken quantity of nutrition and taken quantity of each food, the other is the relation between blood conditions and the increasing or decreasing rate of the weight. The results are as follows. 1) When those of normal blood specific gravity are compared with those of low one from the point of nutrition taking, the former turn out to take more nutritious elements more than the latter. There are a meaningful relation between total blood specific gravity and each nutritious elements, calory, protein, iron, carbohydrate, Vitamin A and Vitamin B, there being P less than 0.05. 2) Those of normal blood specific gravity compared with those of low one from the viewpoint of the quantity taking each food, have a tendency to take both animal food and vegetable food much more. 3) There is a close interrelation between total blood specific gravity and blood conditions, haemoglobin, the number of red blood corpuscle and hematocrit, there being P less than 0.001. 4) Studying the relation between the increasing or decreasing rate of the weight of women engaged in agriculture and total blood specific gravity, we can conclude that the fatter they grow the higher the average value of gravity becomes; their average value 1.052 indicates fatness 3 degrees; blood pressure becomes unusual when the fatness degree rises; the great number of people who have normal blood pressure have the normal weight. From the abovementioned, we suggest that it should be necessary to examine the normal value of blood specific gravity of women engaged in agriculture.
