BACKGROUND: Subjective well-being (SWB) plays an essential role in general health. Although beneficial effects of selected micronutrients and foods on SWB have been reported, they do not reflect the impact of the habitual diet on SWB. Therefore, the purpose of this study is to investigate the association between adherence to the Chinese Dietary Guidelines (CDG) with SWB.
METHODS: This study combined a cross-sectional survey and a daily diary investigation. The cross-sectional survey was conducted on 1,433 students from 8 universities in southern China between October and November 2020. The daily diary investigation was conducted in November 2022, collecting 10-day daily data from 115 students at two universities in southern China over ten consecutive days, resulting in 1,020 valid matched daily responses. Adherence to the CDG was assessed by the China Prime Diet Quality Score (CPDQS), SWB was measured by the Index of Well-being (IWB) and the Affect Valuation Index (AVI). Correlation analysis, multiple regression analyses, and hierarchical regression were conducted to examine the associations of adherence to the CDG with its components, and SWB.
RESULTS: The cross-sectional survey revealed significant predictors of SWB, including adherence to the CDG (β = 0.24, p<0.001) and its components: cereals and tubers (β = 0.07, p = 0.024), vegetables and fruits (β = 0.11, p<0.001), dairy/soy/nuts (β = 0.11, p = 0.002), and condiments and alcoholic beverages (β = 0.08, p = 0.002). The daily diary investigation showed positive associations between adherence to the CDG (β = 0.19, p<0.001), and its components: vegetables and fruits (β = 0.11, p = 0.001), dairy/soy/nuts (β = 0.06, p = 0.009), animal source food (β = 0.06, p = 0.026), and condiments and alcoholic beverages (β = 0.07, p = 0.026), with higher levels of daily SWB.
CONCLUSIONS: Adherence to healthy dietary patterns such as the CDG, rather than focusing on individual components in isolation, is associated with better SWB. Furthermore, the consumption of CDG components had an impact on SWB, although the specific effects varied between the two studies. This study offers modest evidence supporting the role of the CDG in promoting positive mental health.

This perspective article shares unique insights from the extensive experience of the US Department of Agriculture Nutrition Evidence Systematic Review branch in conducting systematic reviews on dietary patterns and health outcomes to inform the Dietary Guidelines for Americans. Methodological approaches for reviewing dietary patterns research are described, including approaches to operationalizing definitions and analyzing labeled dietary patterns. The review also describes techniques for synthesizing dietary patterns research across life stages in systematic reviews that inform food-based, federal dietary guidance. Current research activities and recommendations for how to improve or address gaps in dietary patterns research in the future are also discussed.

UNASSIGNED: Overweight and obesity constitute a new challenge in low-income and middle-countries. The obesity prevention programme, called \'5-2-1-0\', promotes healthy eating habits, physical activity and limited screen time among young people.This study aimed to assess adherence to the \'5-2-1-0\' recommendations and to study multiple risky behaviours among adolescents in nine countries in sub-Saharan Africa.
UNASSIGNED: Meta-analyses with a random effect were used to calculate overall prevalence. Non-random patterns of the co-occurrence of the four risky behaviours were explored using observed/expected prevalence ratios. Data came from the Global School-based Health Survey and 18 314 adolescents were considered.
UNASSIGNED: Among the participants, 12.7% (95% CI 7.5% to 19.0%) had overweight and 3.2% (95% CI 1.1% to 6.1%) had obesity. In almost all countries studied, girls were more affected by overweight and obesity than boys.While only 0.2% (95% CI 0.1% to 0.4%) of the adolescents fully complied with the recommendations, 4.8% (95% CI 3.1% to 6.9%), 28.4% (95% CI 22.4% to 34.8%), 43.8% (95% CI 41.9% to 45.8%) and 17.0% (95% CI 11.8% to 23.0%), respectively, combined 1, 2, 3 and 4 risky behaviours among the four \'5-2-1-0\' criteria. The most observed combination was found for co-occurrence of three risky behaviours: insufficient fruit/vegetables consumption, physical activity and non-zero consumption of sugar-sweetened beverages.
UNASSIGNED: In conclusion, the insufficient adherence to \'5-2-1-0\' recommendations and the high prevalence of the co-occurrence of risky behaviours underscore the need to strengthen health interventions and programmes to prevent obesity among adolescents in sub-Saharan Africa.

Canada promulgated mandatory front-of-pack labelling (FOPL) regulations in 2022, requiring pre-packaged foods meeting and/or exceeding recommended thresholds for nutrients-of-concern (i.e., saturated fat, sodium, sugars) to display a \"high-in\" nutrition symbol. However, there is limited evidence on how Canadian FOPL (CAN-FOPL) regulations compare to other FOPL systems and dietary guidelines. Therefore, the objectives of the study were to examine the diet quality of Canadians using the CAN-FOPL dietary index system and its alignment with other FOPL systems and dietary guidelines.
Nationally representative dietary data from the 2015 Canadian Community Health Survey-Nutrition survey (n = 13,495) was assigned dietary index scores that underpin CAN-FOPL, Diabetes Canada Clinical Practice (DCCP) Guidelines, Nutri-score, Dietary Approaches to Stop Hypertension (DASH) and Canada\'s Food Guide (Healthy Eating Food Index-2019 [HEFI-2019]). Diet quality was examined by assessing linear trends of nutrient intakes across quintile groups of CAN-FOPL dietary index scores. The alignment of CAN-FOPL dietary index system compared with other dietary index systems, with HEFI as the reference standard, was examined using Pearson\'s correlations and к statistics.
The mean [95% CI] dietary index scores (range: 0-100) for CAN-FOPL, DCCP, Nutri-score, DASH, and HEFI-2019 were 73.0 [72.8, 73.2], 64.2 [64.0, 64.3], 54.9 [54.7, 55.1], 51.7 [51.4, 51.9], and 54.3 [54.1, 54.6], respectively. Moving from the \"least healthy\" to the \"most healthy\" quintile in the CAN-FOPL dietary index system, intakes of protein, fiber, vitamin A, vitamin C, and potassium increased, while intakes of energy, saturated fat, total and free sugars, and sodium decreased. CAN-FOPL showed moderate association with DCCP (r = 0.545, p < 0.001), Nutri-score (r = 0.444, p < 0.001),  and HEFI-2019 (r = 0.401, p < 0.001), but poor association with DASH (r = 0.242, p < 0.001). Slight to fair agreement was seen between quintile combinations of CAN-FOPL and all dietary index scores (к = 0.05-0.38).
Our findings show that CAN-FOPL rates the dietary quality of Canadian adults to be healthier than other systems. The disagreement between CAN-FOPL with other systems suggest a need to provide additional guidance to help Canadians select and consume \'healthier\' options among foods that would not display a front-of-pack nutrition symbol.

Nutrition security - access to food that promotes well-being and prevents or treats disease, particularly among racial and ethnic minority populations, lower income populations, and rural and remote populations - is a national priority. Leading causes of death and disability in America, such as heart disease, stroke, cancer, and diabetes that disproportionately affect minorities are linked to preventable diet-related risk factors. Mounting evidence indicates that adherence to a lower-carbohydrate dietary pattern is associated with weight maintenance, improved blood glucose and insulin control, lower blood pressure, reduced markers of inflammation, and a more favorable lipid profile. Additionally, prior concerns regarding the higher fat and cholesterol content of this dietary pattern are less founded in modern research. The inclusion of a lower-carbohydrate option that meets all essential nutrient requirements aligns with the contemporary movement toward more flexibility and precision nutrition. Most important, a lower-carbohydrate option positions the Dietary Guidelines for Americans to more accurately reflect the current scientific evidence and more effectively address the metabolic health of the nation. Further, it has the potential to improve nutrition security by addressing metabolic diseases that disproportionately affect people from historically marginalized racial, ethnic, socioeconomic, and cultural backgrounds. Given that most American adults are living with at least one diet-related chronic metabolic disease, updating the Dietary Guidelines for Americans to recognize and reflect the poor health status of the general population is prudent and urgent.

Accurate assessment of toddler diet quality is essential for understanding current intakes and evaluating the effect of interventions and programs to promote healthy eating and prevent chronic disease.
The goal of this article was to assess the diet quality among toddlers using two different indices appropriate for 24-mo-old toddlers and compare differences in scoring between the measures by race and Hispanic origin.
We used cross-sectional data from 24-mo-old toddlers participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Infant and Toddler Feeding Practices Study-2 (ITFPS-2), a national study that includes 24-hour dietary recall information from children enrolled in WIC at birth. The main outcome measure was diet quality using both the toddler diet quality index (TDQI) and the healthy eating index (HEI)-2015. We derived mean scores for overall diet quality and for each component. We examined associations between the distribution of diet quality scores across terciles and by race and Hispanic origin using Rao-Scott chi-square tests of association.
Nearly half of the mothers and caregivers self-identified as Hispanic (49%). Diet quality scores were higher when using the HEI-2015 compared with the TDQI (56.4 vs. 49.9, respectively). The difference in component scores was largest for refined grains, followed by sodium, added sugars, and dairy. Toddlers from Hispanic mothers and caregivers had significantly higher component scores for greens and beans and dairy but had lower scores for whole grains (P < 0.05) than those for the other racial and ethnic subgroups assessed.
We found noteworthy differences in toddler diet quality depending on whether the HEI-2015 or TDQI is used, and children of different racial and ethnic subgroups may be differentially classified as having high or low diet quality depending on which index is used. This may have important implications for understanding which populations are at risk of future diet-related diseases.

Cervical cancer is preventable and treatable through regular screening and follow-up. However, the utilization of cervical cancer screening may vary widely based on individual lifestyles. The purpose of this study was to examine the differences in the adherence to cervical cancer screening guidelines in various dietary groups. Our study included 21,376 women from the United States and Canada, aged 30-69 from the Adventist Health Study-2, a large population-based prospective cohort study. Modified Poisson regression with robust variance estimation was used to determine the prevalence ratios of cervical cancer screening behavior in participants following five different dietary patterns (non-vegetarians, semi-vegetarians, pesco-vegetarians, lacto-ovo-vegetarians, and vegans). All analyses were adjusted for age, race/ethnicity, marital status, education, personal income, body mass index, smoking, alcohol use, exercise, and family history of all female cancer. Vegetarians, in general, had similar screening prevalence as non-vegetarians. However, vegans were 16% less likely to have had a Pap test compared to non-vegetarians (prevalence ratio (PR) = 0.84, 95% confidence interval 0.81-0.86). Women who were younger, Black, married, more educated, had a family history of all female cancer, had a higher income, and exercise reported higher compliance to a Pap test. It remains to be seen whether vegan women in Adventist Health-2 experience a higher incidence of cervical cancer or are diagnosed at a later stage compared to non-vegetarians.

Dietary factors associated with stroke risk are still rather unknown. The aim was to examine the association between adherence to healthy dietary patterns and incidence of stroke among 25,840 individuals from the Swedish Malmö Diet and Cancer Study cohort. Dietary data were obtained using a combination of a 7-day food record, diet questionnaire, and interview. A Swedish Dietary Guidelines Score (SDGS), including five dietary components based on the current Swedish dietary guidelines, and a modified Mediterranean diet score (mMDS), composed of ten dietary components, were constructed. Over a mean follow-up period of 19.5 years, 2579 stroke cases, of which 80% were ischaemic, were identified through national registers. Weak, non-significant associations were found between the dietary indices and the risk of stroke. However, after excluding potential misreporters and individuals with unstable food habits (35% of the population), we observed significant inverse association (p-trend < 0.05) between SDGS and mMDS and total and ischaemic stroke (HR per point for total stroke: 0.96; 95% CI: 0.92−1.00 for SDGS and 0.95; 95% CI: 0.91−0.99 for mMDS). In conclusion, high quality diet in line with the current Swedish dietary recommendations or Mediterranean diet may reduce the risk of total and ischaemic stroke.

The overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors\' ability to adhere to recommendations. Approaches to meet survivors\' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis.
