JOURNAL FREE ACCESSMale mice of seven strains (ICR, C3H, C57BL, CDF1, BDF1, BALB/c, and DBA/2) were examined for their sucrose taste threshold by the two-bottle test. The concentration of sucrose solution in one of the two bottles was raised from -3.5 to 1.0 (log M) stepwise every two days. The threshold was judged in two different ways as follows: (1) The lowest concentration at which sucrose intake became significantly larger than distilled water (DW) intake (THR·t); (2) The lowest concentration at which sucrose intake exceeded the mean+SD value of DW intake at low sucrose concentration (THR·SD). In the ICR strain, the largest SD of the sucrose preference was observed at 0.5log M, where the maximum preference was observed. Individuals showing a strong preference at this concentration showed a larger THR·t than other individuals. The THR·SD was unable to detect the relationship between sucrose preference and threshold. These results indicate that the THR·t is appropriate for examining both strain difference and individual difference of sucrose taste in mice.View full abstractDownload PDF (1013K) -

JOURNAL FREE ACCESSThe effects of a short and long acyltriglyceride, SALATRIM, on lard-induced accumulation of body fat and disorder of lipid metabolism were investigated in rats, in comparison with those induced by fish and safflower oils. When rats were fed a diet rich in lard (39% of calorific content as lard) for one month, white adipose tissue mass, triglyceride (TG) and total cholesterol (TC) contents in the liver and plasma were greatly increased, as compared with controls fed a standard diet. These adverse effects on lipid metabolism were prevented by adding SALATRIM to the lard diet (at a ratio of 1: 1), but not by adding safflower oil. Addition of fish oil was also effective in reducing the plasma levels of TG and TC, although it raised the lipid peroxide level in the liver. The concentration of plasma free fatty acids was increased by the high-lard diet as well as by the lard-safflower oil diet and lard-SALATRIM diet, but was decreased by the lard-fish oil diet. The mass of brown adipose tissue, a site of diet-induced thermogenesis, was increased by the lard-fish oil diet or the lard-SALATRIM diet. These results indicate that accumulation of triglycerides and cholesterol in the liver and white adipose tissue induced by a high-lard diet are prevented and amended by SALATRIM.View full abstractDownload PDF (1189K) -

JOURNAL FREE ACCESSLactobacillus helveticus-fermented milk (sour milk) contains the angiotensin I-converting enzyme inhibitory tripeptides Val-Pro-Pro and Ile-Pro-Pro. A placebo-controlled, double-blind study was conducted to investigate the hypotensive effects of 160g sour milk drink per day administered continuously over a period of 8 weeks in individuals who had mild or moderate hypertension untreated with drugs (sour milk group; male/female=6/9, mean age 52.4±6.5 years, Systolic blood pressure/Diastolic blood pressure (SBP/DBP)=159±12/93±6mmHg: placebo group; male/female=6/9, mean age 51.5±5.9 years, SBP/DBP=159±12/94±9mmHg). The results revealed that SBP and DBP were significantly decreased in the sour milk group, compared to those before the start of sour milk intake. In the placebo group, in contrast, no changes in blood pressure were observed during the intake period. A significant difference in the decrease of blood pressure was found between the two groups. In addition, no adverse reactions such as dry cough, digestive tract symptoms or abnormal changes were observed. These results suggest that sour milk is useful for controlling blood pressure in subjects with mild or moderate hypertension without drug treatment.View full abstractDownload PDF (1219K) -

JOURNAL FREE ACCESSWe investigated the relationship between methods of food cutting and mastication properties or ease of chewing. The Rangiri method, which cuts food into chunks, rendered food easier to chew than the Sengiri method, which cuts food into fine strips, in the case of burdock root, Japanese white radish and celery. However, in the case of carrot and cucumber, there was no obvious difference between the two cutting methods. Next, we measured the distribution of particle size for chewed foods resulting from each cutting method. This revealed that the Rangiri method produced a more homogeneous distribution of food particle size than the Sengiri method. This suggested that food prepared by the Rangiri method was easier to form into a mass within the oral cavity during chewing. The Rangiri method was also considered superior to the Sengiri method by sensory evaluation. These results show that the Sengiri method appears unsuitable for all foods, especially for people who have low chewing activity.View full abstractDownload PDF (759K) -

JOURNAL FREE ACCESSWe have examined the protective effect of feeding mulberry (Morus alba) leaves against the development of diabetes mellitus in the NOD mouse, a model of type 1 diabetes. Mulberry leaves supplied at 5% in normal chow significantly retarded the appearance of diabetes in terms of hyperglycemia and polydipsia as markers. The present results suggest that intake of mulberry leaves may be beneficial for preventing and/or retarding the development of type 1 diabetes.View full abstractDownload PDF (552K) -
