Background The associations between sugary beverages and genetic predisposition to depression risk remain unclear.Aims This study aimed to investigate the associations of sugar-sweetened beverages(SSBs),artificially sweetened beverages(ASBs)and natural juices(NJs)with depression and to assess whether these associations were modified by genetic predisposition.Methods We used data from the UK Biobank of 180599 individuals aged 39-72 years who were depression-free at baseline.Dietary intake of SSBs,ASBs and NJs was accessed by a 24-hour dietary recall between 2009 and 2012.The Polygenic Risk Score for depression was estimated and categorised as low(lowest tertile),intermediate(tertile 2)and high(highest tertile),.Cox proportional hazard and substitution models were conducted to evaluate hazard ratios(HRs)and 95%Cls.Results Over the 12-year follow-up,4915 individuals developed depression.Higher consumption(>2 units/day)of SSBs(HR:1.26,95%CI 1.12 to 1.43)and ASBs(HR:1.40,95%Cl 1.23 to 1.60)were both associated with an increased risk of depression.However,moderate consumption(>0-1 units/day)of NJs was associated with a lower risk of depression(HR:0.89,95%CI 0.83 to 0.95).Furthermore,genetic predisposition did not modify these associations(p interaction>0.05).In substitution models,the HRs for depression risk were 0.94(95%CI 0.89 to 0.99)and 0.89(95%CI 0.85 to 0.94),respectively,when 1 unit/day of SSBs or ASBs was replaced by an equivalent intake of NJs.Conclusions Higher consumption of SSBs and ASBs was associated with an increased risk of depression;in contrast,moderate consumption of NJs was inversely associated with a lower risk of depression.In theory,substituting SSBs and ASBswith NJs would suppose a reduction of depression risk. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

[Objective] This study was conducted to develop a new kind of ginseng walnut composite milk beverage. [Method] The flavor and emulsifier and stabilizer in ginseng walnut milk beverage were investigated by sensory evaluation and stability test. [Result] The amounts of ginseng extract, sucrose, complex emulsifier, sodium caseinate and carrageenan stabilizer added in the beverage were 20%, 6%, 0.3%, 0.4% and 0.1%, respectively. The complex emulsifier consisted of monoglyceride and sucrose fatty acid ester with a ratio of 1:2. The ginseng walnut milk prepared according to this process tastes fine and smooth with unique ginseng flavor, as well as good stability. [Conclusion] This study could provide good reference for develop- ment and production of ginseng walnut composite milk beverage. 展开更多
