JOURNAL FREE ACCESSA study was conducted to determine the effects of dietary icosapentaenoic acid (IPA) on plasma lipid metabolism. Twelve women (mean age of 22.3 years) participated. After one week on a control diet without IPA, an experimental diet enriched with sardine (IPA daily intake: 3.9g) was given for another 2 weeks with (IPA group) or without (Fish group) additional IPA capsules containing 1.8g/day. The following results were obtained.
1) The serum IPA concentration increased from 17.5±4.2 (SE) to 195.0±2.4μg/ml in the Fish group and to 277±14.3μg/ml in the IPA group.
2) Serum triglyceride levels tended to decrease and apolipoprotein C II concentrations significantly decreased in both groups.
3) The triglyceride content of the very-low-density lipoprotein (VLDL) fraction decreased in both groups, and the decrease was larger in the IPA group.
4) The cholesterol content of the low-density lipoprotein (LDL) fraction slightly reduced in both groups. Additional IPA supplementation significantly decreased the serum concentrations of total cholesterol and apolipoprotein B, associated with a decrease in the apolipoprotein content of the LDL fraction.
These results suggest that dietary IPA supplementation decrease VLDL synthesis at a daily intake of 3.9g, produces a concomitant decrease in LDL synthesis at a higher intake amounting to 5.7g/day, and that the supplementation may be favorable for preventing vascular atheroscierotic changes.View full abstractDownload PDF (752K) -
Saturation Curve of Number of Consumed Food Items Accompanying Increase of Number of MealsLiu Asato, Yuzo Hiroi, Tomoko Shirota, Hiroyuki Toyokawa, Sumie Shinjo ...1992 Volume 50 Issue 5 Pages 275-283

JOURNAL FREE ACCESSThe number of different food items consumed may increase accompanying the number of meals and reach a saturation point. The method of analysis is described in detail. Thirty female students studying food sciences and nutrition were asked to list all the food items they consumed in each meal for 5 consecutive days in October to November, 1989. Five hundred and three food items were consumed in 450 meals. The average number of items consumed in a meal was 11.6 and 29.1 per day. One hundred items were consumed in 20 meals. Each item was listed with its consumption frequency. Rice was consumed in at least one out of the meals. A saturation value of 626 items was theoretically obtained based on the assumption that a full survey had been undertaken. The students had an adequate food consumption. This research method was determined to be suitable for surveying “what are eaten” since all items were listed. A standardized approach method for precisely naming food items was considered necessary.View full abstractDownload PDF (797K) -

JOURNAL FREE ACCESSBeni-koji was extracted with ethanol and fractionated with ethyl acetate, n-butanol or water, in order to elucidate its antihypertensive activity. These fractions were fed to spontaneously hypertensive rats (SHR) in 1% NaCl diets for 15 days. The blood pressure of the group fed water-extract lowered. In another line of experiment, SHR were fed diets supplemented with γ-aminobutyric acid (GABA), which is a hypotensive component of the water-extract of beni-koji (0.09mg/100g diet). Although the control diet raised the blood pressure of SHR by 10mmHg, 0.1mg GABA/100g diet did not. However, addition of 1mg GABA/100g diet significantly repressed it similarly to the water-extract fraction. I. v. injection of water-extract fraction and 1mg GABA/rat induced the hypotensive effect in SHR.
These results indicate that GABA is one of the important antihypertensive substances in beni-koji and the others are soluble in water and ethanol.View full abstractDownload PDF (603K) -

JOURNAL FREE ACCESSRegarding lunches served at day nurseries, elementary and junior high schools as well as meals served at dormitories of a high school and a university, a series of survey on actual supplies of fat soluble components, dietary fibers and minerals that are considered important to prevent atherosclerosis was performed. Foodstuffs actually served from January to March, 1990 for 30 days or 25 days continuously were assayed based on the food tables and the results were summarized:
1) The ratio of fat energy in each meal was from 21.5% to 29.4%.
2) The balance of fatty acid was as follows: P/S 1.57, n-6/n-3 4.4 at the nurseries, P/S 0.64 and 0.71, n-6/n-3 6.8 and 7.1 at elementary and junior high schools, and P/S 1.06 and 1.79, n-6/n-3 6.0 and 5.8 at the dormitories; high school (females) and university (males). E/PUFA was 0.45-0.71 and supplies of cholesterol 81mg at the nurseries, 91mg and 107mg at the elementary and junior high schools, and 343mg and 240mg at the high school and university dormitories.
3) Dietary fibers were noted at 5.0g at the nurseries, 6.1g and 7.3g at the elementary and junior high schools, and 16.3g and 15.1g at the high school and university dormitories.
4) As to the balance of supplied minerals, a gradual decrease was noted with Ca/Mg from 6.87 to 1.40 while a gradual increase was noted with Na/K from 0.90 to 1.80 with advancing ages of the subjects. Sodium chloride per 1, 000 kcal of supplied energy was within the targeted intake level for adults in either case except that being a little much at the university dormitory.View full abstractDownload PDF (895K) -
