The present study was done to examine the status of dietary sodium intake and dietary sources of sodium among Chinese adults. Data were obtained from China National Nutrition and Health Surveillance (CNNHS) 2010–2012. All adults recruited in this study provided complete dietary data on three-day consecutive 24-h dietary recalls combining with the household weighing method. Sodium intake was adjusted for energy to 2000 kcal/day using the residual method. Average sodium intake was 5013 (95% Confidence Interval, CI: 4858, 5168) mg/day, and 92.6% of adults’ sodium intake exceeded the standard in the Chinese proposed intake for preventing non-communicable chronic diseases (PI-NCD). The salt added to food was the main contributor to daily sodium intake, representing 69.2% of the total sodium consumption. The proportion of sodium from salt was different in some subgroups. The contribution ranged from 64.8% for those who came from urban areas aged 18–49 years old to 74.7% for those who came from rural areas with education levels of primary school or less, and sodium from soy sauce was the next highest contributor (8.2%). The proportion of the subjects with sodium intake contributed by flour products was higher in the north with 7.1% than the south with 1.4%. The average consumption of sodium among Chinese was more than the recommended amount, and salt was the main source of sodium.

This study aims to examine association between sodium intake and overweight/obesity among Chinese children and adolescents. Data were obtained from China National Nutrition and Health Surveillance (CNNHS), 2010–2012. All participants recruited in this study aged 7–18 years old and provided complete dietary data on three-day consecutive 24 h dietary recalls combining with the household weighing method. Body Mass Index (BMI) was used to define overweight/obesity, and waist-to-height ratio (WHtR) was used to define abdominal obesity. Sodium intake showed association with risk of overweight/obesity assessed by BMI in the highest tertile group with OR of 1.48 (95%CI 1.13–1.94) and 1.89 (95%CI 1.33–2.67) for WHtR. After adjusted for gender, age, household income, area, energy, carbohydrates, protein, fat, saturated fatty acids, and fiber intake, the relationship between sodium intake and overweight/obesity and abdominal obesity are not changed. The same results were founded in subjects aged 10–18 years old. Our results reveal a positive association between sodium intake and overweight/obesity in Chinese children and adolescents, independent of energy consumption.

Many studies have reported the relationship between eating rate and childhood overweight/obesity, while results remain inconclusive. The present study was done to estimate the association between eating rate and childhood overweight/obesity through a systematic review of prevalence studies. Relevant studies were searched by two independent researchers in databases including PubMed, Embase, Cochrane Library, and Web of Science, and data were collected from relevant studies published through June 2023 using predefined inclusion/exclusion criteria. A summary estimate was calculated using a random-effect model, and subgroup analysis was performed to explore sources of heterogeneity. Data from 16 published studies were eligible for inclusion. Fast eating was associated with a higher risk of overweight/obesity compared with a medium eating rate (OR = 1.80; 95% CI: 1.49, 2.18), and slow eating showed a declined overweight/obesity risk among children and adolescents (OR = 0.65; 95% CI: 0.52, 0.81). Subgroup analysis performed according to age showed that in all age groups, eating fast was positively correlated with overweight/obesity, while eating slowly was negatively associated with overweight/obesity. According to our study, eating rate was closely related to childhood overweight/obesity, and eating fast was associated with an increased likelihood of being overweight/obesity. In the future, it will be necessary to understand the factors that influence fast eating and develop methods to slow down the eating rate in children and adolescents.

Background/Objectives: High-quality diets are increasingly recognized as a promising strategy for alleviating mental health problems. This study aimed to evaluate the association between adherence to the EAT-Lancet diet (ELD) and depression and anxiety using a systematic review and meta-analysis of observational studies. Methods: A comprehensive literature search of PubMed, Web of Science, and Embase was conducted. Two independent reviewers screened titles, abstracts, and full texts and extracted data, with any discrepancies resolved by consensus. Results: Ultimately, eight unique studies (10 comparisons) met the predefined inclusion criteria. Adjusted effect estimates (odds ratios (ORs) or hazard ratios (HRs)) and corresponding 95% confidence (95%CI) intervals were extracted and pooled using random-effects meta-analysis. Between-study heterogeneity was quantified with the I² statistic. Compared with the lowest ELD adherence, the highest adherence was associated with a lower risk of depression (OR = 0.78, 95% CI 0.73–0.85; I² = 85.0%); a similar inverse association was observed for anxiety (OR = 0.83, 95% CI 0.79–0.86; I² = 0%) and the co-occurrence of depression and anxiety (HR = 0.76, 95% CI 0.68–0.85; I² = 0%). Conclusions: Our findings indicate that, compared with low adherence, high adherence to the ELD is associated with beneficial effects on mental health and may inform dietary recommendations for the early prevention and intervention of depression, anxiety, and their co-occurrence.
