RESUMO

Hypertensive patients who adopt a sodium-restricted diet have difficulty maintaining this change, and this could increase stress. On the other hand, soup rich in umami substances (dashi) was reported to reduce indexes of anxiety and stress. The objective of this study was to measure mood and physiological stress indexes during administration of a sodium-restricted diet with and without an umami substance (free L-glutamate) by a cross-over randomized, single-blind, placebo-controlled trial in Japanese female university students. The baseline was measured for 5 days followed by a sodium-restricted diet intervention phase that lasted for 10 days. The Profile of Mood States questionnaire was administered, a stress marker in saliva (chromogranin-A) was measured, and the amount of sodium intake was confirmed from 24 h urine collection samples. Results showed that the sodium reduction was verified by 24 h urine excretion. The percentage of change in the stress marker from the baseline showed that the stress level in group without the umami substance was significantly higher than that in the group with the umami substance (p = 0.013) after receiving a sodium-reduced diet for 6 or more days, indicating that stress was alleviated. This study suggested that umami substances might help to ameliorate stress during a sodium-reduced diet, especially in the initial phase.

RESUMO

In recent years, the prevalence and problem of overweight and obesity in Taiwanese children have increased. There are many reports that the excessive intake of sugar increases the risk of lifestyle-related disease. However, sugar intake in Taiwanese children is not known. In this study, we investigated sugar intake from sugar-sweetened beverages, snacks and desserts among school-age children in Kaohsiung, Taiwan. We also tried to determine the relationship between sugar intake and body mass index (BMI). We contacted all the public elementary schools (10 schools) in a district, Kaohsiung, and obtained permission from 3 schools. The survey subjects were 410 (210 boys, 200 girls) school-age children (7, 10 and 12 y old). A nutrition survey was conducted using 3 non-consecutive days of the 24 h dietary recall method for sugar-sweetened beverages, snacks and desserts. Height and weight were measured. Sugar intakes were not significantly different among the different genders or ages (p>0.05) and average intake of all was 51.6 g/d. Percentages of each sugar in total intake were sucrose 60%, glucose 18%, fructose 16%, and lactose 6%. The intake of glucose and fructose may have come from isomerized sugar. Contributions of sugar-sweetened beverages and snacks (desserts) were 83.5% and 16.5%, respectively. Among the sugar-sweetened beverages the top 3 sources were tea (22%), milk tea (19%) and milk beverages (18%). A relationship between sugar intake and BMI was not observed. In conclusion, sugar intake of the children was higher than the WHO recommendation due to the high intake from beverages; however, sugar was not the cause of the high obesity rate.

RESUMO

In Japan, the national health policy "Healthy Japan 21 (second term)" was introduced in 2013 to support prevention of lifestyle-related disease. Policy has also been recently revised on the promotion of nutrition education (shokuiku). Community-based food and nutrition actions were developed based on those policies and aimed to reinforce the linkages across the food chain, looking along its length "from field to food", including production, processing, preparation, eating and disposal. Local government is responsible for identifying the important food and nutritional problems, to devise and group effective actions on the basis of local health issues. The National Institute of Public Health (NIPH) is responsible for carrying out public health staff training on policy-based health issues. Training carried out by the NIPH, the Japan Dietetic Association and the Japan Public Health Association was designed to create an enabling environment for nutrition action. The community-based actions, including nutrition education and information, are carried out by several bodies, including local government, schools, facilities, volunteer groups, residents' associations, and commercial companies, to establish sustainable food systems promoting healthy diets. The community-empowering actions and effective cooperation are reported as good practice models in an annual white paper by the Cabinet Office. Japanese dieticians are expected to share their experiences of local nutrition improvement activities in Japan with international colleagues. Experience from elsewhere, including from Japanese dieticians working in developing countries, should also be applied on their return.

RESUMO

Because of the tastiness of sugars, it is easy to consume more than an adequate amount. There are many research reports that excess sugar intake contributes to dental decay, obesity, diabetes etc. Continuing economic development in Cambodia has made it easier than before for people to consume sugars in their daily life. Currently, isomerized sugar (a mixture of glucose and fructose) made from starches is commonly used in commercial beverages because of its low price. However, in Cambodia and Japan, sugar composition tables that include not only sucrose but also glucose, fructose, lactose and maltose have not been available. Prior to the present nutrition surveys, we made sugar composition tables for both countries. In this study we tried to estimate the intakes of various sugars by children in Cambodia and Japan and to determine the relationship between intake and body weight. Nutrition surveys of children aged 7, 10 and 13 years old were conducted for 3 nonconsecutive days by the 24 h recall method in 89 Cambodian children living in the capital city of Cambodia, Phnom Penh, and 151 Japanese children living in 3 prefectures from north to south. Height and weight of children in Cambodia and Japan were similar until 10 years old but at 13 years old, the Cambodians were shorter and lighter than the Japanese. We could not observe any differences in BMI in either country. The sugar intakes from beverages and snacks were not different among the different gender and age. Thus we combined the mean total sugar intake for Cambodian and Japanese, 28.42 ± 25.28 g and 25.69 ± 16.16 g respectively. These were within the range of WHO recommendations (less than 10% of energy intakes). Cambodian children consumed about 46% of sugars from commercial beverages and snacks and Japanese children 26%. This means that for Cambodians half of the sugars came from isomerized sugar made from starches. Relationships between sugar intake and body weight were not observed in both countries. In conclusion, the Cambodian children consumed about 46% of sugar from glucose and fructose (probably in the form of isomerized sugar), while the Japanese children took 26%; however, the intakes in both countries met the WHO recommendation and there was no relationship to body weight.

RESUMO

While sugar intake is an important factor for obesity, diabetes and dental caries, sugars are also important energy sources, especially for rapidly growing children. Children like sugar-rich sweet foods. However, intake for Japanese children is not known due to a lack of studies and sugar composition data. This study was designed to determine sugar intakes from snacks and beverages in Japanese school children. A nutrition survey was conducted for 3 weekdays for 283 Japanese school children (7, 10 and 13 y old) in 8 prefectures from different areas of Japan. The methods for the survey were the weighing method for school lunches and the 24-h recall method for other foods. To estimate sugar intakes, the sugar composition table that was recently compiled by us for 135 beverages, cakes and other sweets was used. Height and weight were measured. They were similar to Japanese averages. Energy intakes were also similar to the results of the Japanese National Health and Nutrition Surveys. Sugar eaten outside meals was 24.7±15.5 g/d. From the National Health and Nutrition Surveys conducted in 2009, the mean sucrose intake from meals including some home-made cookies for 7-14-y-old children was 5.5 g/d, suggesting the mean total sugar intake of these children was about 30 g/d. This was within the range of FAO/WHO recommendation (less than 10% of energy intake, 49 g for these children. Mean intakes among age groups were not significantly different (p>0.05), but the intake for girls was lower than for boys in the oldest age group (p<0.05). Contributions of each sugar to total intake were sucrose 64%, fructose 14%, glucose 13% and lactose 9%. Fructose and glucose were mainly from isomerized sugar. Contributions of food groups to total intake were beverages 25%, baked goods 19% and ice cream 17%, respectively, covering 61% of all. In conclusion, we revealed that the average sugar intake of Japanese children was within the range of the FAO/WHO recommendation, though the effects of the kind of sugars on health remain to be clarified.
