Asia differs substantially among and within its regions populated by diverse ethnic groups with different cultures and unique diets. Asian Microbiome Project, which is a consortium research project participated by ten Asian countries, is investigating on the gut microbiome diversity which may link with these diverse diets. Thus far, we found country-specific features as well as enterotype-like global variations in the Asian microbiomes. Notably, Japanese have unique features such as less alpha- and beta-diversities, low abundance of potentially pathogenic bacteria groups and high abundance of Bifidobacterium. This may reflect unique Japanese life and dietary styles. Regarding enterotypes, majority of southeast Asian populations carry the Prevotella-type (P-type) in reflection of high consumption of rice. However, a cross-sectional study on the gut microbiota of school-age children on Leyte island in Philippines showed the enterotype-shift from P-type to Bacteroides/Bifidobacterium-type (BB-type), which associated with dietary Westernization. Another cross-sectional study on Thai children further indicated decrease of short chain fatty acid concentration in the feces of children in urban city, who consumed much less vegetables compared with children in rural city. Altogether, although Asian people have evolved their gut microbiomes in association with their unique diets, current urbanization hampers their structure and function. It warrants further studies on the impact of altered gut microbiomes on the health of Asian people.

Serum cholesterol level reduction is an important factor for preventing lifestyle-related disease. Together, search for food materials which reduces serum cholesterol level have come to people' s attention. In this study, we carried out a large-scale and a long-term study to evaluate the effect of brown rice on serum cholesterol level. In brief, we conducted this study using a cross-over design with 90 days of consuming pregelatinized brown rice against non-brown rice. The following results were obtained.1) There was a low drop-out rate: 2.5% (3 of 120 subjects), and many participants replied that this program was easy to join, because the preparing of brown rice was very easy and the contents of the program were very simple.2) Brown rice intake increased bowel movement and improved the participant' s physical condition.3) Serum cholesterol levels were significantly decreased in the subjects starting with abnormal value of serum cholesterol (over 221 mg/dL) by brown rice intake.4) Brown rice intake decreased serum LDL cholesterol in the subjects with initial level of high serum LDL cholesterol (over 140 mg/dL).5) However, serum HDL cholesterol level of brown rice intake group did not change in the subjects of low serum HDL cholesterol levels (under 40 mg/dL). These large-scale studies suggested brown rice has serum cholesterol decreasing effect in people with high cholesterol level.

The koji mold is a useful mold that has been used in the production of Japan’s fermented food like miso, soy sauce, sake (rice wine), and shochu (a distilled beverage) since ancient times. The koji mold is distributed as "Tane-koji” from Tane-koji manufacturers to each brewer. Tane-koji has a long history, dating back to 15th century. It started with the technological development of mixing wood ash when culturing koji mold. In this article/today, I will explain about Tane-koji and koji mold from the point of view of manufacturer.

During infancy, children gradually become able to manipulate utensils in accordance with the development of motor and cognitive abilities. Previous studies on the development of eating skills have mainly examined infants and preschoolers. However, even after preschool age, eating skills continue to develop and become more refined and sophisticated with age. This study examined the development of eating skills after early childhood self-feeding ability had been acquired. Eleven 5-year-old children and sixteen adults were observed while eating curry and rice with spoons. The young children’s spoon manipulations were found to be somewhat simple. For example, food was picked up with a spoon and brought to their mouths in a single action. In contrast, the spoon manipulations of the adults were more complex and complicated. They first gathered the curry and rice into one area and then adjusted the amount and shape for easier intake. The children were frequently observed lifting the plate and sliding the food directly into their mouths. This behavior was never seen in the adult subjects. The adults often performed more refined, coordinated movements using their right and left hands and fingers (e.g., lifting or turning a dish with one’s left hand to more easily pick up rice using a spoon in one’s right hand). The results suggested that self-feeding skills using a spoon are acquired up to the end of preschool age; however, after this period of time, spoon manipulation becomes more multi-functional with age.

1996年より国産小容量PET飲料の販売が解除された。2003年における清涼飲料水生産量1,800万kLのうちPET飲料は56%のシェアを占め,その内の36.4%を500mLが占めている。500mL PET飲料が短期間でこれほど普及したのは,小容量PET飲料は,缶と違って再栓ができるという利点から,飲みかけの状態で長時間持ち歩くことが何らかの問題を生じないか,ということを細菌学的観点から検討する研究を行った。(1) PET飲料からの直接飲用により,口腔内に常在する様々な細菌が混入したが,時間経過とともに減少した。(2) 特に,抗菌性をもつと言われている緑茶飲料,ウーロン茶飲料では減少が急速であり,8時間保存後に生菌は認めなかった。(3) 糖類を含む果汁飲料,アミノ酸を含むスポーツ飲料,デンプンを含むむぎ茶飲料では減少が緩慢であり,8時間保存後でも生菌が多く認められた。(4) 通常は複数回の開栓・飲用があり,その都度細菌の暴露を受けるので,生残は多くなるものと考えられる。従って,特にむぎ茶飲料を飲みかけの状態で長時間持ち歩き飲用することにおいては注意が必要である。(5) Staphylococcus属菌は生菌数の減少が急速なウーロン茶飲料や緑茶飲料でも生残しており,減少が緩慢なむぎ茶飲料などではStreptococcus属菌も検出された。

We conducted a survey for students about lifestyle habitats such as eating habits and monitored skin conditions to study the effects of the eating habit on skin conditions. This eating habit survey showed that n-6/n-3 ratio is on the increase due to the excessive consumption of fat and the insufficient intake of fish. Furthermore, there was a trend that there was a lack of many nutrients. For the relationship between nutrient uptake and skin conditions, there was a significant positive correlation between the take of n-6/n-3 and transepidermal water loss (TEWL), and the consumption of alachidonic acid and icosatrienoic acid and the extent of the incidence of acne. These results suggested that nutrient component taken from eating affects skin conditions. In addition, it is indicated that n-3 or n-6 fatty acid is strongly related to the barrier function of the horny cell layer and the incidence of acne.

We first analyzed the dietary records at a Zen monastery from the viewpoint of nutrition and food intake. The means of the total energy, protein and fat intake were significantly lower than a normal diet. The amounts of other nutrients had the same tendency. The mushrooms and seaweed intakes were extremely better than any other food groups. In addition, we conducted investigations regarding the diet and health of Zen monks training at Zen monasteries to examine their nutrient intake and health condition. The nutrient consumption of Zen monks was high carbohydrates, high dietary fiber, low fat, and low cholesterol, and this was especially conspicuous in the non-animal food consumption group. There were no concerns about their blood parameters. However, a decrease in their QOL is a concern. Finally, to clarify the difference in the serum lipid and blood glucose levels between young Zen monks and middle-aged Zen monks, we investigated their nutrient intake and health conditions. In both groups, no distinct difference was observed in their HDL cholesterol and triglyceride levels. However, the total cholesterol and blood glucose levels of the young group were remarkably higher than those of the middle-aged group. Therefore, this study suggested that physiological changes in the body due to aging affected the total cholesterol and blood glucose levels.

Hesperidin, which is called vitamin P, is a flavonoid compound abundantly occulting in citrus fruit peel. This material is well known to decrease capillary fragility and permeability. In addition, hesperidin is reported to have various physiological activities. Therefore, it has attracted attention as a multifunctional food ingredient. However, the use of this flavonoid in the field of foods has been limited because of its low water solubility. To solve this problem, we developed a soluble derivative of hesperidin, glucosyl hesperidin, which was synthesized by regioselective transglycosylation with cyclodextrin glucanotransferase from Bacillus stearothermophilus. Glucosyl hesperidin was very soluble in water, and its solubility was about 100, 000 times greater than that of conventional hesperidin. Moreover, the metabolic fate of this glucoside was investigated. As a result, it was verified that orally administered glucosyl hesperidin was hydrolyzed?to?hesperidin by small intestinal α-glucosidases, and that released hesperidin was hydrolyzed to hesperetin by β-glucosidases from intestinal bacteria before absorption. Glucosyl hesperidin was also confirmed to exhibit such physiological activities as improvement effect on microcirculation, antihypertensive effect and decrease of serum triglyceride level.?From these findings, glucosyl hesperidin is considered to be available effectively as a soluble vitamin P supplement in the field of functional foods.

Bifidobacterium bacteria, called probiotics, have been reported to exhibit various physiological functions such as positive effects on the human digestion system. A number of products containing the bacteria have been put on the market in the form of fermented milk products.  In order to get sufficient effects in the large intestine, Bifidobacterium bacteria must be the viable form.  But the consumer cannot find products that listed the number of viable cells on the label, except for foods for specified health uses “tokuho”.  Therefore, we carried out the viable count of bacteria in yogurt and drink yogurt (12 items from 8 companies in Japan ) to find a fermented milk product having a high bacterial viable count and high viability during storage after production. As a result, the fermented milk food and drink contained 3×106 to 4×108 cfu/g or ml, and their viabilities during chilled storage were different.  Of these products, the drastic reduction in the viable cells was started in a yogurt after two weeks from the manufacture.  The improvement for maintaining a high viable cells during shelf life was completed, and in some yogurts, no decrease in the viable cells was observed for 1 month when the storage temperature was maintained at 4°C. Also, regarding the tolerance of Bifidobacterium bacteria against artificial digestive fluids in vitro, a difference existed between the manufacturers.

The purpose of this study was to investigate characteristics of bean cooking in the world. The countries investigated were mainly selected by high bean consumption by citizens (an average of over 3.5 kg/year), bean-consumption data having been published in the "World statistics 2017". Other countries were also selected by their research importance. Totally 21 countries or cultural regions were selected for research concerning bean cooking. 86 cook books from all these countries were collected and used as reference books in this study. The recipes involving beans as an ingredient were investigated in each book and 1192 total recipes were found. Detailed data in each recipe, such as species of beans used, the style (e.g. whole or cut) of beans during cooking, seasonings, spices and pot herbs used, were input into Excel. And a database and cross tabulation were made. The characteristics of bean dishes in 21 countries or cultural regions were revealed through the analyses. The kinds of beans used for bean dishes vary according to world regions. Soybeans are used only in East Asian countries, mainly in Japan, Korea and China. Chickpeas and lentils are mainly used in West Asia and surrounding areas. Black beans are used mainly in Mexico and Latin America. Beans prepared for consumption fall into four general styles: whole beans (predominant in most countries), chopped or sliced beans, bean pastes and purees (most common in three Asian countries) and sprouts. The study of seasoning methods for various bean dishes was also conducted. Spices such as pepper, chili, coriander and cumin, are mainly used globally for the seasoning of bean dishes. But in three Asian countries, seasonings such as soy sauce, miso, sake and mirin are more commonly used and the use of other spices is minimum. Beans are cooked by simmering in curries, stews and soups. In addition, beans are often ingredients in salads. A bean-paste dish called hummus, in which beans are mashed and seasoned, are often found in Middle Eastern countries.

The objectives of this study were to evaluate a practical method of determining more accurately conversion factors for calculating the protein content of food from the total nitrogen content (N : P factors) and to propose a reliable procedure for routinely converting total nitrogen data to the protein content. First, mushrooms and vegetables were selected as model foods to explore a novel method of determining N : P factors for the reason that these foods contain high levels of nonprotein nitrogen. These foods were analyzed for total nitrogen content, amino acid nitrogen and nonprotein nitrogen and then the N : P factors were calculated. Based on the results, the novel method for calculating N : P factors was proposed; the N : P factor was defined as the proportion of the amino acid residue content to the total nitrogen content. The average N : P factors calculated by this novel method were 3. 99±0. 76 (mean±SD) for mushrooms and 4. 10±0. 60 for vegetables. Protein contents estimated using these factors were in good agreement with the contents determined by amino acid residues. Second, applying this novel calculation method, the N : P factors for some other foods were investigated. Cereal products and several pulses were determined the novel N : P factors, based on the total nitrogen content and amino acid residues. The averaged factors were 5. 26 for rice, 5. 47 for wheat, 5. 54 for other cereal products and 5. 51 for pulses. Then, the N : P factors for 295 foodstuffs in “the Revised Standard Tables of Food Composition in Japan, Amino Acid Composition of Foods”, were calculated. These results suggested that the N : P factor of 6. 25 commonly used for many foods was not a realistic factor for estimating the protein content of food by converting the total nitrogen. Third, the protein contents of 11 school lunch menus and 2 convenience store lunch boxes were calculated from the total nitrogen content using the novel N : P factors. The proportion of the protein contents multiplied by the novel N : P factors to the traditional protein contents was approximately 84%. The averaged novel N : P factor for 13 menus was 5. 16±0. 10. The protein content of diet meals containing various foods should be multiplied by this value.  It was concluded that this novel calculation method should be practical and suitable for the evaluation of the N : P factors.
