The effect of sucrose solution drinking option (SSDO) on the energy and water intake, body weight, and urinary components —urea-N, allantoin and uric acid— was observed in male Wistar rats (4 weeks old) which were fed either semisynthetic casein or commercial diet for 6 to 28 weeks.
The results obtained were as follows.
1) Increases in energy intake and body weight gain were observed in animals given sucrose solution with each diet. The increases in energy intake of the sucrose solution were larger in the animals of 10 weeks of age and older than in the younger animals. The sucrose ingested with SSDO accounted for 50-60% of the total energy intake. The animals preferred the commercial diet to the casein diet.
2) The suspension of SSDO made the body weight gain minimal in the young animals, although a decrease in body weight at the rate of 1g/day was observed in adult animals.
3) No significant difference in water intake was observed between SSDO animals and non-SSDO animals.
4) Protein intake and urinary urea-N decreased significantly in SSDO animals. Significant differences in excretion of urinary allantoin plus uric acid and of urinary creatinine were observed between SSDO and non-SSDO animals for a week after starting SSDO.

Present experiments aimed to clarify the effects of dietary phospholipids of different origins with different fatty acid compositions on the lipid concentrations in serum and liver of rats. Animals were fed the hypercholesterolemic diet before and throughout the experimental period. Each experimental diet contained 3% krill, egg or soybean phospholipid, 0.9% choline the amount of which corresponded to that contained in these phospholipids or 0.63% EPA+0.53% DHA the amounts of which also corresponded to those contained in these phospholipids, while the control diet contained 5% olive oil. After 2 weeks on the tested diets, total serum cholesterol concentration, which had been elevated by the feeding of the hypercholesterolemic diet, were depressed significantly in all of the phospholipid groups compared to the control group. Hypocholesterolemic effect of krill phospholipid was not so marked as expected from the high contents of ω-3 polyunsaturated fatty acids in the phospholipid. A similar effect on serum total cholesterol concentration was observed in the EPA+DHA groups but not in the choline group. On the other hand, serum high density lipoprotein (HDL-) cholesterol concentrations in all groups were higher than that in the control group, where egg phospholipid showed the markedly elevated value. Liver total cholesterol concentration in the egg phospholipid group was significantly lower. In the krill and soybean phospholipid groups the liver total cholesterol concentrations were lower than in the control group but the differences were not statistically significant. The fatty acid pattern of total lipids in the serum and liver of rats was closely related to the fatty acid pattern of each dietary phospholipid.

We studied changes in the quantities of foods purchased between 1965 and 1985 based on “Yearly Amount of Quantities by Commodities per Household” from “Annual Report on the Family Income and Expenditure Survey”.
Results are as follows:
1) The purchase decreased for many foods which showed an increase tendency or ambiguous tendency during the years surveyed previously.
2) In terms of groups of foods, a decrease after an increase was observed in vegetables and fruits.
3) The tendency observed between 1965 and 1979 of (1) marked inclination for more expensive items within the same or similar food groups, (2) increased purchase of fish, meat, vegetables, etc., and (3) westernization in the respect of raw materials and seasonings was not evident in this survey; they appeared to be stagnant.
4) Changes in the quantity of purchase during 21 years from 1965 to 1985 showed an overall increase, but the increase became gradual after 1973, particularly after 1980.
