Cedar pollen allergies are one of the severe health problems in Japan. Recently, it was reported that symptoms of pollen allergies are attenuated by the intake of functional foods. Euglena is a unicellular organism classified as algae, which is taking notice as a functional food. In this study, the effect of euglena on experimental pollen allergies in mice was investigated.  5 week-old BALB/c male mice were sensitized using Cry j1 by intraperitoneal injection and intranasal instillation. AIN-93M was fed to the negative control and positive control group, whereas euglena, paramylon, and amorphous paramylon were fed (2% in AIN-93M) to each diet group. We determined the incidence of nasal rubbing, liver weight, spleen weight, white blood cell counts, serum IgE and IFN-γ.  In the euglena diet group, the percentage of positive incidences of nasal rubbing mice decreased. It is suggested that euglena may attenuate symptoms of cedar pollen allergies.

The relationship between rice storage conditions and the physicochemical and sensory properties of cooked rice was investigated. Both polished rice (90% yield) and brown rice were stored in the following conditions: (i) 37℃ and 75% relative humidity (RH) for 30 and 80 days; (ii) at room temperature (22.2-27.5℃, 31.3-53.9% RH) for 180 days from May to November. Treated samples of brown rice storage were polished at 90% yield after storage. The increase in fat acidity levels after storage was larger in polished rice storage than in brown rice storage, whereas the increase in reducing sugar levels after storage was larger in brown rice storage than in polished rice storage. After storage for 80 days at 37℃ and 75% RH, the hardness of cooked rice increased, and the stickiness decreased. In addition, compared with the control cooked rice sample, rice quality worsened, hardness increased, and stickiness decreased remarkably after refrigerating cooked rice at 4℃ for 16 h. The peak temperature of gelatinization for rice flour, obtained using DSC, increased after storage but that for rice starch was comparable regardless of storage conditions. This suggests an increase in interactions between rice starch and other ingredients during storage. Sensory evaluation of cooked rice stored at 37℃ and 75% RH suggested that polished rice storage was better than brown rice storage in terms of aroma and taste. In contrast, after storage at room temperature, it was suggested that brown rice storage was better than polished rice storage in terms of appearance and taste.

A hospital for persons with severe motor and intellectual disabilities in Nara prefecture was considered to provide a small amount of a highly nutritious jelly diet. This study examined whether this jelly diet had appropriate physical properties for patients with the dysphagia who were able to eat L1 and L2 foods of the dysphagia diet pyramid. In addition, the reproducibility and taste of the jelly foods were evaluated under different cooking conditions, such as different chefs cooking at different facilities. The results confirmed that all six menus had L1 and L2 physical properties of the dysphagia diet pyramid, despite different cooking conditions. However, in a few menus, the levels of the dysphagia diet pyramid were altered owing to the addition of nutritious food ingredients and distinct cooking environments. Among these menus, some of the levels stepped up to the level of normal food by shifting from L0 to L1 or L1 to L2. To ensure the stable delivery of these foods, it is necessary to standardize the cooking processes and better understand the food ingredients. Concerning taste, the "Chinese cabbage salad with green shiso leaves” on the six menus was rated low following the addition of nutritious food ingredients. Furthermore, a sensory analysis for the facility staff and chefs is required to comprehensively evaluate taste.

This research aims to clarify the characteristics of human behavior while eating meals in co-eating and solitary eating situations. To manipulate eating situations, we observed participants' behaviors (N = 6) under two different experimental settings: a solitary eating condition, in which participants had their meals alone while watching television or using their cellphone, and a co-eating condition, in which participants ate their meals in the course of dyadic conversation with friends. We assessed the participants’ gaze behaviors and eating actions during the meal and compared these between the two eating situations statistically. The results demonstrate that 1) participants in the co-eating condition glanced longer at their own meal compared to participants in the solitary eating condition, 2) participants in the solitary eating condition often stopped their other eating actions while chewing food, and 3) participants in the co-eating condition frequently gathered meal portions using a spoon while looking at their meal. These results suggest that participants in the solitary eating condition enjoyed their meal while watching television or using their cellphone in an informal atmosphere. Meanwhile, participants in the co-eating condition used their meals to coordinate their interactive behaviors with a co-eater. The social functions of co-eating are discussed from a human behavior analysis perspective.

Recent years, the young often eat meals outside their home. When “Shoku-no-Gaibuka” increases, it seems that the young's awareness on eating changes. This study was undertaken to investigate the “Shoku-no-Gaibuka” aspect on the part of young people. An interview survey was conducted with special focus being placed on each interviewee's personality and life-style. The interview sample included 52 young peoples 20-25 years old living in the Metropolitan area. Twenty six of the subjects were men and 26 were women. The result of the interview showed that about 30% at the young usually eat meals away from home. Many of them work until very late at night, moreover they do not eat breakfast. The amount of “Shoku-no-Gaibuka” is not related to the awareness of eating, but the young who usually eat these meals have less interest in their dietary culture and spiritual aspect. The young who usually eat “Shoku-no-Gaibuka” in addition to being unsatisfied with the meal, desire an improvement in their dietary conditions.

Objective: To clarify how elderly women living alone, who were 80 years of age or older, define food activities in their life courses and how they perceive current food activities.Method: The participants were 12 women living alone who were over 80 years old. A semi-structured interview was conducted from August to December 2016 with the consent of the participants. Their conversations were recorded and the verbatim records were analyzed using M-GTA (Modified Grounded Theory Approach).Results: 63 concepts, 15 categories, 2 sub core categories and 1 core category were extracted. Food activity was recognized as a role of the wife and mother. Participants also affirmed their role in the main stages of life. However, as they moved to living alone, they re-evaluated the role they had accepted, and realized that they had moved to activities that were valuable, meaningful, and feasible to them. They were also aware that they had accepted social connections through food activities.Conclusion: Elderly women have accepted the connection with society through food and have changed the meaning and content of food activities according to their individual lives.

This study aimed to clarify the influence of dietary habits and daily intake of fermented milk containing Lactobacillus casei strain Shirota, 1.5×1010 cfu/65 mL/day, on bowel habits in elderly nursing home residents. A total of 20 elderly nursing home residents (2 men, 18 women, age 88.1±6.7 years) participated in this study. We recorded the amount of food intake and bowel habits (defecation frequency and laxative administration) of residents during a designated non-intake period (6 months) and an intake period (6 months). During the intake period, defecation frequency increased from 36.5±13.7 to 41.0±14.4% (p<0.05). Frequency of laxative administration decreased slightly from 26.6±13.0 to 24.9±14.2% (there is no significant difference). Among participants who had improved defecation frequency, the amount of food intake (individual eating rate) was slightly larger than that in those that did not improve defecation frequency (94.0±5.1% vs. 89.1±13.6%). These findings suggest that daily intake of fermented milk containing Lactobacillus casei strain Shirota might provide benefits including improved bowel habits in elderly nursing home residents.

“Adzuki Ann” prepared from Adzuki beans is a popular paste (Ann), which is generally used in Japanese confectionery. In product development and quality control, it is necessary to perform quantitative evaluations using sensory evaluation and chemical analyses. However, few studies have examined the most appropriate methods for assessing the flavor of Adzuki Ann. Therefore, in this study, we focused on the flavor of Adzuki Ann, defined “deliciousness” of Adzuki Ann (Tsubu Ann type; paste with remaining grains), then optimized the method for sensory evaluation, and identified aroma compounds contributing to the flavor. As a result of sensory evaluation of Adzuki Ann used for preparing Dorayaki sweets available in commercial markets, we clarified that Adzuki Ann, which is recognized as “delicious” popularly, has “moderate sweetness and rich Adzuki flavor”. This accorded with the definition of delicious Adzuki Ann flavor. Additionally, sensory evaluation scores of Adzuki flavor showed a strong correlation with maltol and cyclotene content which are important aroma compounds contributing to Adzuki flavor. In particular, as a result of the addition of cyclotene to Adzuki Ann, sensory evaluation scores of Adzuki flavor decreased significantly. This suggests that cyclotene may be an inhibitor of Adzuki flavor.

The principal 705 Japanese foods were selected from the Standard Tables of Food Composition in Japan — 2010 — (Standard Tables) because these foods are known to contain available carbohydrates including starch, glucose, fructose, sucrose maltose and/or lactose. Individual available carbohydrate contents were calculated and tabulated based both on the estimated saccharide (carbohydrate minus dietary fiber) content of each selected food in the Standard Tables and the starch and sugar content of the food included in The McCance and Widdowson’s The Composition of Foods, USDA National Nutrient Database for Standard Reference and other sources. Because the compiled tabulated form, the Japanese Starch and Sugars Presumptive Composition Tables (JSSPCT), is harmonized with the Standard Tables, one can utilize the data in the JSSPCT as a reference for research and other purposes until and after the Ministry of Education, Culture, Sports, Science and Technology or other national organization publishes the official tables for available carbohydrate composition of foods in Japan.

Barley have a component of soluble fiber called β-glucan which have β-(1→3) and β-(1→4)-linkages. Studies on the physiological functions of barley have been rapidly increasing in terms of the cholesterol-lowering effect, serum glucose and insulin normalization including the second meal effects, decreased body fat accumulation, and appetite control. It has been scientifically proven that the soluble dietary fiber in barley, β-glucan, might reduce the risk of cardiovascular disease (CVD). The Food and Drug Administration (FDA) has stated that daily intakes of 3 g or more of soluble fiber (β-glucan) in barley may reduce the risk of heart disease by its ability to lower total cholesterol and LDL-cholesterol. The European Food Safety Authority (EFSA) supported the following health claim for barley β-glucan: 1) maintenance of normal blood LDL-cholesterol concentrations, 2) reduction of post-prandial glycemic responses, and 3) digestive function (normal stool frequency). Recent clinical studies have suggested that the consumption of barley and its products might reduce many risk factors associated with the metabolic syndrome, namely diabetes and dyslipidemia. In our inter vention study in Japanese men and women, the consumption of high β-glucan barley reduced waist circumstaznce and visceral fat area. This review presents recent information about the health function of barley β-glucan.

This study investigated the stress-reducing effect of kabusecha containing of high amounts of theanine, a nutritional component of green tea, on daily high-stress person. The subjects were 109 college students and staffs who live in different environments (12 men, 97 women, 19-67 years). Twenty-nine person with high stress (2 men, 27 women, 19-58 years old) were selected by Stress Response Scale-18 (SRS-18), one of the subjective stress evaluation methods. As a single-blind study, a 30-days tea challenge was conducted on them divided into two groups, one is kabusecha containing theanine and the other is barley tea without theanine. The quantitative stress level was assessed with SRS-18 and salivary amylase and blood pressure as objective stress evaluation methods. The quantitative stress levels were assessed with salivary amylase and blood pressure as objective stress evaluation and SRS-18 as subjective evaluation. As a result, the salivary amylase level and SRS-18 score decreased significantly in the kabusecha group. It was speculated that kabusecha has an anti-stress effect by suppressing the autonomic nervous system pathway, especially the sympathetic nervous-adrenal medullary axis. Interestingly, blood pressure and SRS-18 score also decreased significantly in the barley tea group. It was considered that barley tea induces a stress-reducing effect by a stress response activation pathway different ,from that of kabusecha. These findings suggested that kabusecha has the stress-reducing effect of on someone with high stress in daily life using a combination of subjective and objective measures of stress. In the future, it is expected that as one of the stress coping methods, people could select the tea according to individual stress by clarifying the involvement of various nutritional components in the psychological stress-reducing effect.

This study investigated the relationship between nutrients and COVID-19 infection in order to provide useful suggestions for infection control in terms of enterobactera. Based on the data taken from a national health and nutrition examination survey, the present study examined the correlation coefficients between each intake of 40 kinds of nutrients and the cumulative number of COVID-19 cases in 12 areas in Japan. The number of COVID-19 cases per 100,000 people were cumulatively counted using three indices; 1) positive cases of PCR test results, 2) inpatients, 3) deaths reported by the Ministry of Health, Labor and Welfare. The results revealed that the intake of carbohydrate and carbohydrate energy ratios had significant and negative correlations with the number of positive PCR test results in the 12 areas. In contrast, the intake of animal proteins, animal fat, monounsaturated fatty acid, fatty energy ratios, and animal protein energy ratios correlated positively and significantly with the number of positive PCR test results. Regarding the number of inpatients, only carbohydrate energy rates had a significant and negative correlation. No other significant and positive or negative correlations were found between the intake of nutrients and the number of inpatients. As for the number of death cases, intake of the carbohydrate energy ratios and vitamin K had significant and negative correlations with it. In contrast, intake of animal protein energy ratios had a significant and positive correlation with it. These findings suggest nutrients seem to prevent or promote COVID-19 infection. Further research is necessary to determine whether these results can be applied to individual participants longitudinally. To do so, the relationship between the immune system and enterobacteria should be examined from the perspective of nutritional physiology.
