AbstractObjective:The study aimed to evaluate the homocysteine and cobalamin status of German vegans and determine whether the intake of very small amounts of foods of animal origin can improve this status.Design and setting:Cross-sectional study, Germany.Subjects:The dietary and nutritional intakes of 131 vegans (73 women, 58 men; a range: 20.2–82.1 years) were evaluated using a general questionnaire and two food–frequency questionnaires.Results:The prevalence of inadequate cobalamin status in volunteers of the German Vegan Study was 28.2%, and that of hyperhomocysteinaemia, 38.1%. Moderate vegans were affected to a lesser extent than were strict vegans. Duration of veganism and cobalamin concentration were inversely correlated (Spearman'sr= -0.175,P= 0.047). Folate concentration and erythrocyte aspartic acid aminotransferase activity were not correlated with plasma homocysteine concentration, but duration of veganism correlated positively with homocysteine concentration (Spearman'sr= 0.319,P< 0.001). Cobalamin and homocysteine concentrations were inversely correlated (when controlling for duration of veganism;r= -0.602,P< 0.001).Conclusion:Cobalamin status needs to be improved in order to minimise the risk of hyperhomocysteinaemia.

The purpose of this study was to evaluate the association between non-nutritive sweetener (NNS) consumption and stress and anxiety, among a sample of college students. Two-hundred and twenty-seven students from a large mid-western university participated in this cross-sectional study. Students completed an online survey that evaluated NNS using a validated food frequency questionnaire. Stress and anxiety were evaluated using previously validated instruments. Most students reported very low/low/average concern for stress (63.9%), and had low/moderate anxiety (82.3%). Participants experiencing high and very high levels of stress had significantly higher NNS consumption compared to those with a very low and low risk, and concern for stress ( p < .046; d = 0.28). There was no difference however for NNS intake and anxiety. Reduction of artificial sweetener intake may be associated with stress levels among college students. However, more research is needed to examine any causal relationship between artificial sweetener intake and stress.

Abstract Background In China, many people are apt to participate in regular physical examination as a precaution. Some simplified food frequency questionnaire have been designed and used. However, the effectiveness of questionnaire is absent. This study was conducted to examine the reliability and validity of simplified food frequency questionnaire (SFFQ) used among physical examination adults in southwest region of China. Methods This study was a cross sectional study among physical health examination adults in Southwest region of China. A total of 239 participants aged 20-65 were conducted during February to June in 2019. The performance of the SFFQ was evaluated by the mean of three-day 24-hour dietary recalls (3R24). The relative validity and agreement was assessed by the Pearson`s correlation and intra-class correlation coefficients(ICC) respectively. Results The median energy-adjusted ICC of food groups between SFFQ2 and SFFQ1 was 0.59 (range: 0.49-0.73) and the ICC of nutrients was 0.47(range: 0.39-0.76). The Pearson correlation showed the validity between the SFFQ1 and 3R24, which ranged from -0.086 to 0.93 for food and and 0.21 to 0.71 for nutritions, respectively. Energy-adjustment slightly increased the correlation coefficients. Conclusions The reliability and validity of the SFFQ was acceptable. It could be an appropriate dietary assessment tool for future epidemiological studies in physical health examination adults among Chinese in southwest China.

We aimed to examine the association between soft drink consumption and asthma and lung function among Qatari adults. In the cross-sectional study, we used data from 986 Qatari participants aged 20 years and above attending the Qatar Biobank Study. Usual consumption of soft drink was assessed using a food frequency questionnaire. Lung function was measured by spirometry and asthma was based on self-report. The associations between soft drink consumption and asthma and lung function were assessed using multivariable logistic and linear regression, respectively. In total, 65 participants out of 986 (6.6%) reported having asthma. A clear dose-response relationship between soft drink consumption and asthma was found. High soft drink consumers (≥7 times/week) were 2.60 (95% CI 1.20–5.63) times more likely to have asthma as compared to non-consumers. The association was partly mediated by BMI and inflammation. Diet soft drink consumption was positively associated with asthma (OR 1.12 (95% CI 1.02–1.23)) but not with lung function. Regular soft drink consumption was inversely associated with FEV1, but not with FVC. In conclusion, soft drink consumption is positively associated with asthma in Qatari adults. The association is partly mediated by obesity and inflammation. Limiting soft drink consumption should be taken into consideration for asthma prevention.
