Following up with recovered coronavirus disease 2019 (COVID-19) patients is necessary. Given the importance of psychological function accompanied by significant effects of food quality, we want to examine the association between food quality score (FQS) and mental disorders among recovered COVID-19 patients. This case-control study was performed on 246 eligible adults. A validated food frequency questionnaire (FFQ) was used to evaluate dietary intake. We using Depression Anxiety Stress Scales, Insomnia Severity Index, Pittsburgh Sleep Quality Index, and 36-Item Short Form Health Survey questionnaires to evaluate the psychological function. Logistic regression analysis was conducted to estimate the odds ratio (OR) and 95% confidence intervals (CIs) for score categories of the FQS index and psychological function in multivariate-adjusted models. Only in case subjects, we found significant associations between adherence to the FQS diet and depression, anxiety, and stress in the crude model (OR, 0.796, 95% CI, 0.661–0.958, p = 0.016; OR, 0.824, 95% CI, 0.707–0.960, p = 0.013; OR, 0.824, 95% CI, 0.709–0.956, p = 0.011, respectively). These associations remained significant in all two adjusted models. However, no significant associations were found between FQS and psychological functions in the control group. Our data suggests that overall food quality intake is associated with depression, anxiety, and stress symptoms during the post-infection period. Also, adequate daily intakes of fruits, legumes, nuts, and whole grains are associated with reduced risks of psychological impairment and sleep disorders which are common among recovered patients.

This study was conducted to evaluate changes in hydrogen breath test results and nutritional improvements when Korean adults diagnosed with lactose intolerance consumed processed milk containing approximately 10 g of lactose continuously. Participants consumed 240 mL of intervention food daily for a month and visited the research institute before and after the intervention to undergo nutrient intake survey and hydrogen breath tests. Data from 32 participants, with a mean age of 52.9 years, were analyzed. Hydrogen breath tests showed a significant decrease in hydrogen levels at all but baseline and the first of five 20-minute intervals of expiratory hydrogen concentration measurements. The third and fourth measurements showed the most significant changes (p < 0.001). The gastrointestinal symptoms showed a decreasing trend. Nutrient intake analysis demonstrated significant increases in animal protein (p < 0.001), calcium (p < 0.001), percentage of energy from protein (p = 0.032), vitamin A (p = 0.032), and retinol levels (p = 0.023). Regarding dietary habits, significant improvements were observed in nutritional quotient variables, including nutritional score (p = 0.042) and balance (p = 0.034). This study suggests that the removal of lactose and dairy products is not necessary for individuals with lactose intolerance. Incorporating low-lactose processed milk into their usual diet might be a practical dietary management strategy.

This study was conducted to analyze diet and health-related factors based on the income level of single-adult households using data from the Korea National Health and Nutrition Survey (KNHANES). Among those who participated in the 2016–2018 KNHANES, 951 single-adult households aged 19 to 64 were selected, and factors such as general characteristics, physical characteristics, dietary behaviors, health behaviors, and the prevalence of chronic diseases were analyzed. The high-income group had higher frequency of eating out, better dietary status generally, higher recognition rate of nutrition labels than the other groups. The rate of alcohol consumption and smoking was higher in the high-income group of single-adult households, while the rates of anxiety and depression were higher in the low-income group. Additionally, the use of dietary supplements decreased as income level decreased. Among chronic diseases, hypertension, diabetes, and dyslipidemia had the lowest prevalence in the middle-income group and the highest prevalence in the low-income group. These results suggest that diet and health behaviors vary by income level in single-adult households and may be associated with the prevalence of chronic diseases. Future systematic studies should be conducted to determine the causal relationships between these factors.
Obesity is a significant global health concern that not only increases metabolic disorders risks but also impacts mental health, particularly affecting women due to hormonal fluctuations and societal pressures. This study investigated anti-obesity and anti-anxiety effects of lemon balm (

This systematic review and meta-analysis aimed to evaluate the effectiveness of almond consumption on serum C-reactive protein (CRP) and malondialdehyde (MDA) levels in individuals at risk of cardiovascular disease (CVD). An electronic database search was performed on PubMed, Web of Science, Scopus, and the Cochrane Library from inception through October 2024. Summary effect size measurements were calculated using random effects model estimation and were reported as weighted mean differences (WMDs) along with 95% confidence intervals (CIs). A total of 258 articles were identified, and 13 randomized controlled trials (RCTs) were included in the systematic review and meta-analysis. The meta-analysis of eleven RCTs, which involved a total of 544 participants, indicated that almonds significantly reduced levels of CRP (WMD, −0.28 mg/L; 95% CI, −0.52, −0.04; p = 0.02). However, we found no significant benefit of almond consumption in improving serum MDA levels, and due to the limited number of studies, the examination of MDA was conducted only qualitatively. This study supports the conclusion that almond consumption has favorable effects on CRP levels in individuals with CVD risk factors. More high-quality trials are needed to confirm these findings.
