Methods A total of 6974 （boys 3558, girls 3412） children aged 6-13 years participated in the study. Each participant’s height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio （95% confidence internal （CI）] of obesity was 7.6% [as the reference group （ref.）], 10.1% [1.36（1.07, 1.74）], and 11.6% [1.46（1.21, 1.75）], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio （95% CI）： 1.36 （1.17, 1.59）]. The prevalence [adjusted odds ratio （95% CI）] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00（1.31, 3.07）], 12.7% [1.52（1.23, 1.88）], 11.5% [1.52（1.18, 1.95）], and 10.4% [1.41（1.03, 1.94）], respectively, which was higher than that of regular milk drinkers [7.6 % （ref.）]. The prevalence [adjusted odds ratio （95% CI）] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55（1.26, 1.90）], 16.2% [1.36（1.09, 1.70）], and 15.3% [1.24（1.03, 1.50）], respectively, which was much higher than that of regular milk drinkers [12.8% （ref.）]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design.展开更多

Cultivation conditions with agro-toxics, lipids instability, and tendency for mycotoxin contamination restrict its application in human nutrition. Therefore, organic agriculture is an alternative to use the properties of rice bran. Rice bran beverage is a new cereal product from organic rice. This work presents the preliminary results of the chemical and rheological studies of a bath pasteurized rice bran beverage. Compared with integral defatted milk, soy extracts, and brown rice low-fat milk, the rice bran beverage studied in this work presents itself as an important source of minerals and unsaturated lipids. All essential amino acids were found in this product. Glutamic and aspartic acids were predominant. Bath pasteurization at boiling water temperature for 15 and 30 min was adequate for microbiological safety. Refrigeration storage for 20 days, evaluated by pH and acidity variations, was ideal for assessment of the beverage conservation time. The beverage viscosity was of the Newtonian standard behavior, and its viscosity during storage was not a good parameter to evaluate shelf life. Sensory preference tests showed positive perspectives for this new beverage.展开更多

The results reveal that the uncoated tinplate shows a poor corrosion resistance and the corrosion type is detinning. During the initial stage of immersion, EIS spectrum consisted of two capacitance arcs with obvious time-constant dispersion effect, which was attributed to the two-dimensional and three-dimensional inhomogeneous distribution of the electrode surface. With the increase of immersion time, the capacitance arc of high frequency shrunk and degenerated, due to the corrosion of tin coating. The pore resistance of tin coating and the charger transfer resistance of substrate, which are determined from the electrochemical equivalent circuit, can be used as the indicators of tinplate corrosion process. The decrease of the pore resistance of tin coating indicates that the corrosion degree of tin layer becomes more severe, whereas the decrease of the charger transfer resistance of substrate implies that the corrosion degree of steel substrate also becomes more severe as the immersion time prolongs.展开更多

文摘The degree of processing is rarely considered an independent factor in the health effects of fruit juices and beverages(FJBs)consumption.In fact,the consumption of ultra-processed foods has been shown to pose health risks.In this study,we first integrated 4 systems used to classify the degree of food processing and then classified FJBs into three major categories,low(minimal),moderate and high.Second,we compared the differences in attitudes towards FJBs in dietary guidelines.Third,we integrated the results of existing epidemiological surveys,randomized controlled trials,and animal experiments to explore the health risks associated with consuming FJBs.Deepening the processing of FJBs has been found to lead to an increased risk of diseases.Dietary pattern,nutrients,addition agents and consumer preferences may be influential factors.Finally,we investigated whether there were any changes in the health benefits of 100%fruit juices produced by different processing methods.In conclusion,minimally/moderately processed 100%fruit juices provide more health benefits than highly processed fruit beverages.The results support the need to consider the extent of FJBs processing in future studies to adjust official nutritional recommendations for beverage consumption.
文摘Objective:To evaluate the health effects of sugary beverage consumption among adolescent students in Guangxi.Methods:In three cities of Guangxi(Nanning,Liuzhou,and Guilin),we investigated the consumption of sugary beverages by distributing a self-administered Functional Assessment Questionnaire of Life Health System and a Dietary Behavior Questionnaire(this paper analyzes only the part of sugary beverage consumption)to adolescent students in four schools,aiming to find out the general health status of the students and also to assess the effects of sugary beverages on the functional system health of adolescent students.Results:A total of 953 adolescent students between the ages of 14 and 24 were surveyed.Among them,46.17%consumed sugary beverages once a week;37.46%consumed them 2-3 times;11.52%consumed them more than 3 times;and 4.83%consumed them every day.The mean score of Functional Assessment Questionnaire of Life Health System was 32.There was a positive correlation between the frequency of consumption of sugary beverages and the overall systemic function assessment score(P<0.05),and the rank of the total score elevated by 0.314 times for each increase in the level of consumption.Compared to those who drink sugary beverages at least once a day,drinking them once a week showed a statistically significant difference(P<0.05).However,there was no statistically significant difference between drinking 2-3 times a week and more than 3 times a week(P>0.05).The correlation between consuming sugary beverages once a week and 2-3 times a week and endocrine system scores was also statistically significant(P<0.05).Conclusion:More than half of the students in the surveyed areas consumed sugary beverages two or more times a week,and the higher the frequency of consumption,the higher the scores of systemic function assessment.Health education on sugar reduction among adolescents should be strengthened.

文摘Objective To explore the associations between sugar-sweetened beverage （SSB） consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 （boys 3558, girls 3412） children aged 6-13 years participated in the study. Each participant’s height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio （95% confidence internal （CI）] of obesity was 7.6% [as the reference group （ref.）], 10.1% [1.36（1.07, 1.74）], and 11.6% [1.46（1.21, 1.75）], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio （95% CI）： 1.36 （1.17, 1.59）]. The prevalence [adjusted odds ratio （95% CI）] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00（1.31, 3.07）], 12.7% [1.52（1.23, 1.88）], 11.5% [1.52（1.18, 1.95）], and 10.4% [1.41（1.03, 1.94）], respectively, which was higher than that of regular milk drinkers [7.6 % （ref.）]. The prevalence [adjusted odds ratio （95% CI）] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55（1.26, 1.90）], 16.2% [1.36（1.09, 1.70）], and 15.3% [1.24（1.03, 1.50）], respectively, which was much higher than that of regular milk drinkers [12.8% （ref.）]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design.
文摘Rice bran is a solid residue from rice polishing that is used in animal nutrition and rice oil production. Cultivation conditions with agro-toxics, lipids instability, and tendency for mycotoxin contamination restrict its application in human nutrition. Therefore, organic agriculture is an alternative to use the properties of rice bran. Rice bran beverage is a new cereal product from organic rice. This work presents the preliminary results of the chemical and rheological studies of a bath pasteurized rice bran beverage. Compared with integral defatted milk, soy extracts, and brown rice low-fat milk, the rice bran beverage studied in this work presents itself as an important source of minerals and unsaturated lipids. All essential amino acids were found in this product. Glutamic and aspartic acids were predominant. Bath pasteurization at boiling water temperature for 15 and 30 min was adequate for microbiological safety. Refrigeration storage for 20 days, evaluated by pH and acidity variations, was ideal for assessment of the beverage conservation time. The beverage viscosity was of the Newtonian standard behavior, and its viscosity during storage was not a good parameter to evaluate shelf life. Sensory preference tests showed positive perspectives for this new beverage.

文摘The corrosion process of tinplate in deaerated functional beverage was investigated by using electrochemical impedance spectroscopy (EIS) combined with scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) techniques. The results reveal that the uncoated tinplate shows a poor corrosion resistance and the corrosion type is detinning. During the initial stage of immersion, EIS spectrum consisted of two capacitance arcs with obvious time-constant dispersion effect, which was attributed to the two-dimensional and three-dimensional inhomogeneous distribution of the electrode surface. With the increase of immersion time, the capacitance arc of high frequency shrunk and degenerated, due to the corrosion of tin coating. The pore resistance of tin coating and the charger transfer resistance of substrate, which are determined from the electrochemical equivalent circuit, can be used as the indicators of tinplate corrosion process. The decrease of the pore resistance of tin coating indicates that the corrosion degree of tin layer becomes more severe, whereas the decrease of the charger transfer resistance of substrate implies that the corrosion degree of steel substrate also becomes more severe as the immersion time prolongs.
