Dietary trajectory profiles of French adults over time: Multicriteria analysis of sustainability

Abstract Despite the urgent need for sustainable dietary transitions, few studies have examined current dietary trajectories using longitudinal data. This study aimed to identify dietary consumption trajectory profiles over an 8-year period (2014-2022) while assessing their sustainability in a multicriteria approach. Consumption data from NutriNet-Santé cohort participants were collected using FFQs in 2014, 2018 and 2022. Dietary trajectory profiles were modeled using group-based multi-trajectory based on factors from Principal Component Analysis on energy-adjusted consumption data (n = 17,187). Profiles were analyzed for sustainability (environmental and nutritional dimensions) using multi-adjusted mixed-effects models. Six trajectory profiles (P) were identified. P0 (considered as reference) had average consumption for all food groups, with increased plant-based intake over time. In comparison, P1 had the highest baseline alcohol (+301%) and offal intake, increasing processed meat (+74%) and decreasing offal over time. P2 had higher milk (+187%) and sweet drinks intake, increasing animal substitutes (+1737%) and whole-grain products. P3 had higher nuts (+680%) and legumes intake, increasing egg (+166%) and reducing fruit juice. P4 had high fish (+39%) and fruit intake, increasing butter (+53%) and reducing alcohol. P5 had higher pork (+143%) and red meat intake, increasing fish (+31%) and reducing dairy. Initially, P3 and P4 had the lowest GHG emissions (-18%, -49% vs. P0), best nutritional profiles, and higher organic food consumption. P5 had the greatest environmental impact (+51%) and the lowest nutritional scores. Over time, P0 reduced GHG emissions and improved nutritional scores. P3 and P4 showed minimal changes, while P5 had the greatest GHG emissions decrease (-14%) and nutritional quality improvements. Identifying ongoing dietary transition trajectories, our findings contribute to optimizing targeted actions aimed at promoting sustainable dietary consumption habits. Key messages • Regardless of initial dietary preferences, French adults exhibit an overall trend over time towards increased intake of plant-based foods and decreased intake of red meats, at varying scales. • French adults exhibit varying degrees of transition towards more sustainable diets, with an overall decrease in GHG emissions from food consumption and an improvement in their nutritional profiles.

Food insecurity impacts diet quality and adherence to the gluten-free diet in youth with celiac disease.

Celiac disease (CD) is an autoimmune gastrointestinal disorder that requires a strict lifelong gluten-free diet (GFD). Gluten-free (GF) foods are more expensive and less readily accessible than gluten-containing foods, contributing to an increased risk for food insecurity (FI). The study aimed to determine associations between GF-FI, sociodemographic risk factors and child dietary adherence and diet quality (DQ). A 26-item, cross-country online survey was administered through social media to parents of children with CD on the GFD. The survey elicited household and CD child sociodemographic and clinical characteristics (e.g., duration of CD), measures of household FI, child DQ and GFD adherence, and parents' concerns related to GF food. Household GF-FI was evaluated using the validated Hunger Vital Sign™ and the US Department of Agriculture Six-Item Short Form Household Food Security Survey Module. GF-FI occurred in 47% of households with children with CD with >30% reporting low to very low food security. Sociodemographic risk factors identified included lower income, renters, rural residency, single-parental households, and having children with additional dietary restrictions (p < 0.001). Regardless of FI status, a majority of households reported experiencing significantly higher GF food expenditure. GF-FI was associated with reduced adherence to the GFD, increased consumption of processed GF food, and lower intakes of fresh fruits and vegetables and GF grains among children with CD (p < 0.05). GF-FI is prevalent in this multiethnic cohort of households with CD children and is associated with worsening DQ and GFD adherence. Policy interventions are urgently needed to address GF-FI.

Loneliness and low fruit and vegetable consumption among adults in Japan

BackgroundLoneliness is the distressing feeling that arises when a person's network of social relations is perceived as being inadequate in some way. Research has linked loneliness to a number of detrimental health outcomes. There is also some evidence that lonely individuals are more likely to engage in poorer health behaviors. However, as yet, there has been comparatively little attention paid to the relation between loneliness and dietary behavior. In particular, there has been little focus on the association between loneliness and fruit and vegetable intake.ObjectiveThe aim of this cross-sectional study was to examine the association between loneliness and low fruit and vegetable consumption in the Japanese general population.MethodsData were analyzed from 3,410 Japanese adults collected in an online survey in early 2023. Information was obtained on past-week fruit and vegetable consumption with a single-item measure, while loneliness was assessed with the Three-Item Loneliness Scale. Information was also collected on sociodemographic characteristics, physical health status, health-risk behaviors and depressive symptoms. Logistic regression was used to assess associations.ResultsOne in twenty (5.3%) adults reported low fruit and vegetable consumption. In a fully adjusted analysis loneliness was associated with higher odds for low fruit and vegetable consumption (OR: 1.14, 95%CI: 1.04–1.26). In sex- and age-stratified analyses loneliness was significantly associated with low fruit and vegetable consumption in both women and middle-aged adults, although confidence intervals overlapped for this association across all of the sex and age groups in the fully adjusted analyses.ConclusionsLoneliness is associated with low fruit and vegetable consumption among adults in Japan. As loneliness and inadequate fruit and vegetable intake have both been linked to poorer health outcomes, the results of this study underscore the potential importance and public health benefits of reducing loneliness in Japan.

Can mobile apps facilitate more sustainable and healthier diets? A systematic review

Abstract Background One third of all greenhouse gas emissions come from the food system, and current diets are insufficient to meet environmental and public health goals. Digital health apps offer promise to change behaviour, but little is known about the effects of different types of apps. This systematic review assessed the effectiveness of mobile apps in facilitating dietary changes across adults from high-income countries. Methods Seven electronic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, Global Health, GreenFILE, Web of Science), two trial registries (Cochrane Trials and Clinicaltrials.gov), and Google were systematically searched for intervention studies aiming to facilitate dietary change. Interventions were characterised by their use of messaging (e.g., motivational statements) and personalised features (e.g., tailored nutrition advice). Outcomes for three food groups were synthesised through meta-analysis. Results Of the 5261 identified records, 21 met the eligibility criteria and were included. Interventions, recruiting 73,973 participants in total, lasted from three days to six months. Overall positive changes were observed in daily servings of fruit and vegetables (0.59, 95% CI 0.20, 0.99), legumes (0.05, 95% CI 0.01, 0.08), and meat (-0.14, 95% CI -0.23, -0.05), remaining significant after removing non-randomised controlled trials. Changes in fruit and vegetable intake were more pronounced for users of apps with messaging components (0.75, 95% CI 0.18, 1.32) and personalisation (0.67, 95% CI 0.16, 1.19), and meat intake changes were larger for messaging-based apps (-0.21, 95% CI -0.27, -0.15) than apps without these features. Conclusions Our findings suggest to practitioners and policymakers that mobile apps could be a useful and innovative way to change behaviour. Within a wider behaviour change approach, apps could help facilitate diets that meet food-based dietary guidelines, are predominantly plant-based, and are protective of environmental and human health. Key messages • Overall, the results from 21 studies showed positive dietary changes towards more fruits, vegetables, and legumes and less meat consumption following the use of mobile apps. • Apps including messaging and personalised elements appeared most effective and may be important for driving changes in fruits, vegetables, and meat consumption.

Type 2 diabetes prevention: genetic association analysis of dried fruit intake and disease risk.

Prior research has suggested an inverse correlation between dried fruit intake and type 2 diabetes mellitus (T2DM), yet the causal link remains uncertain. This study seeks to investigate the potential causal impact of dried fruit intake on T2DM, covering cases both with and without various complications, as well as glycaemic traits, using a two-sample Mendelian randomisation (MR) approach. Using MR analysis with genome-wide association study summary statistics, the primary analysis investigated the causal relationship between dried fruit intake and T2DM, both with and without complications, as well as glycaemic traits, employing the inverse variance weighted method. Supplementary analyses were conducted using MR-Egger and the weighted median method. Heterogeneity and intercept tests were utilised to evaluate the robustness of the study outcomes. The results show a significant association between dried fruit intake and T2DM without complications, as well as fasting insulin. Sensitivity analyses confirmed the robustness of the results and the independence from multicollinearity. However, no association was found between dried fruit intake and T2DM with various complications or other glycaemic traits. The significant association between dried fruit intake and T2DM without complications and fasting insulin persisted even after adjusting for BMI. This study offers genetic evidence endorsing the protective effects of dried fruit intake against T2DM, specifically for cases without complications, and in regulating fasting insulin. These findings suggest that dried fruit intake might serve as a primary preventive strategy for T2DM.

Associations of the Healthy Beverage Index (HBI) and the risk of Breast Cancer (BrCa): a case–control study

BackgroundBreast cancer (BrCa) is one of the leading causes of cancer-related deaths. There are several factors for getting BrCa, including some changeable factors related to lifestyle like unhealthy dietary patterns, so modifying them can prevent one third of the complications and deaths caused by BrCa. Therefore, we decided to investigate the relationship between Healthy Beverage Index (HBI) and the risk of BrCa.MethodsIn this hospital-based case–control study, 253 patients with BrCa and 267 non-BrCa controls were enrolled. Food consumption was recorded to calculate the HBI score using a semi-quantitative Food Frequency Questionnaire (FFQ). Additionally, by using binary logistic regression analysis with adjustment for confounders, the relationship between HBI and the risk of BrCa were assessed. HBI was established by Duffey et al. and is used to evaluate the overall quality of beverage intake and identify changes in consumption.ResultsMean ± SD of age and BMI of the study participants were 47.92 ± 10.33 years and 29.43 ± 5.51 kg/m2, respectively. Patients with BrCa considerably outperformed controls in terms of waist circumference (WC), age at first pregnancy, history of abortion, and number of children(Pvalue < 0.05). Compared with those in the lowest quartile of HBI, subjects in the highest quartile had higher intake of energy, carbohydrate, protein, fat, fiber, sodium, potassium, calcium, magnesium, zinc, vitamin C, E, B9, fruits, vegetables, fish and nut as well as lower BMI and WC (Pvalue < 0.05). After adjustment for potential confounders, individuals in highest compared to lowest quartile of HBI had significantly lower risk of BrCa for total population (odds ratio (OR): 0.40; 95% confidence interval (95%CI): 0.21–0.76, Pvalue < 0.05), premenopausal (OR: 0.38; 95% CI: 0.16–0.92, Pvalue = 0.013), and postmenopausal (OR: 0.27; 95% CI: 0.10–0.78, Pvalue = 0.023).ConclusionFindings of this study suggested that higher HBI score decreased the risk of BrCa. However, further investigation is needed.

Cancers attributable to diet in Italy.

Cancer burden can be reduced by controlling modifiable risk factors, including diet. We provided an evidence-based assessment of cancer cases and deaths attributable to diet in Italy in 2020. We considered dietary factor-cancer type pairs for which the World Cancer Research Fund/American Institute for Cancer Research - Continuous Update Project reported either 'convincing' or 'probable' evidence of causal association. Relative risks were retrieved from recent meta-analyses and dietary intakes (around 2005) from a national food consumption survey. Sex-specific population attributable fractions (PAFs) were computed by comparing the distribution of dietary intakes in the Italian population against counterfactual scenarios based on dietary recommendations. Using data from national cancer and mortality registries in 2020, we estimated the number of attributable cancer cases and deaths, assuming ~15-year lag period. Unhealthy diet accounted for 6.3% (95% CI: 2.5%-9.9%) of all cancer cases in men and 4.5% (95% CI: 1.7%-7.4%) in women. PAFs of colorectal cancer were 10.5% and 7.0% for any intake of processed meat, 3.3% and 2.0% for high red meat, 4.8% and 4.3% for low dairy products, and 7.9% and 9.0% for low fiber intakes in men and women, respectively. PAFs for low intake of non-starchy vegetables and fruit ranged from 0.8% to 16.5% in men and 0.6%-17.8% in women for cancers of the aerodigestive tract. The estimated cancer burden associated with unfavorable dietary habits in Italy is considerable, but appears lower than for other high-income countries, reflecting the typically Mediterranean diet.

Sex differences in the prevalence of metabolic syndrome and associated factors in the general population of Mongolia: A nationwide study.

The prevalence and factors associated with metabolic syndrome (MetS) between men and women in Mongolia were compared using secondary data from the STEPwise approach to non-communicable disease risk factor surveillance conducted in 2019. In total, 5,695 participants (2,577 males and 3,118 females) aged 18-69 years old were enrolled in the study. The prevalence of MetS was 37.4% in total and the prevalence was significantly higher in women (39.2%) than men (35.2%, P = 0.002). The most prevalent MetS components were abdominal obesity in women (74.2%) and high blood glucose levels in men (58.7%). All of the 2,128 participants who were categorized into MetS met the criteria of abdominal obesity. Factors associated with MetS included being 30-69 years old compared to 18-29 years old, low and moderate physical activity levels compared to high levels, history of hypertension and diabetes mellitus, and a high body mass index (overweight and obesity) compared to a normal body mass index in both sexes. Additional factors included Buryat ethnicity compared to Khalkh ethnicity, living in Ulaanbaatar, no education compared to primary education, higher monthly income, and currently drinking in men; and smoking and sufficient fruit and vegetable intake in women. Significant differences were observed between men and women in terms of the prevalence of MetS, components of MetS, and factors associated with MetS. To reduce MetS prevalence in Mongolia, sex-specific programs should be designed to promote health behavior, such as reducing alcohol consumption in men and smoking in women.

Mediterranean diet lowers risk of new-onset diabetes: a nationwide cohort study in China

BackgroundThe Mediterranean diet (MD) has shown promising results in preventing type 2 diabetes, particularly in Mediterranean and European populations. However, the applicability of these benefits to non-Mediterranean populations is unclear, with contradictory findings in the literature.MethodsIn this study, we included 12,575 participants without diabetes at baseline from the China Health and Nutrition Survey (CHNS). Dietary intake was measured by three consecutive 24-h dietary recalls. The Mediterranean diet adherence (MDA) was measured by a score scale that included nine components of vegetables, legumes, fruits, nuts, cereals, fish, red meat, dairy products, and alcohol. New-onset diabetes was defined as self-reported physician-diagnosed diabetes during the follow-up.ResultsDuring a median follow-up of 9.0 years, 445 (3.5%) subjects developed diabetes. Overall, there was an inverse association between the MDA score and new-onset diabetes (per score increment, HR 0.83, 95% CI 0.76–0.90). Moreover, age, sex, BMI, and energy intake significantly modified the association between the MDA score and the risk of new-onset diabetes (all P interactions < 0.05). Greater fruit, fish, and nut intake was significantly associated with a lower risk of new-onset diabetes.ConclusionThere was an inverse association between Mediterranean diet adherence and new-onset diabetes in the Chinese population.

Association between dried fruit intake and kidney function: research from univariate and multivariate Mendelian randomized studies

ObjectivesObservational studies have identified an association between dried fruit intake and kidney function. However, these studies have limitations such as vulnerability to confounders and reverse causality bias. Therefore, this study aimed to explore the potential causal relationship between dried fruit intake and kidney function.MethodsA two-sample Mendelian randomization (MR) study was conducted using a large-scale genome-wide association study dataset to investigate the causal relationship between dried fruit intake and kidney function markers (blood urea nitrogen (BUN), creatinine (CR), uric acid (UA), cystatin C (CyC), hematuria, microalbuminuria). The main analytical method was inverse variance weighting. In addition, we applied the MR Egger and weighted median to assess the robustness of the results. Finally, Multivariate Mendelian randomization (MVMR) was used to estimate the direct effect of dried fruit intake on kidney function markers.ResultsThe univariate MR analysis showed that increased dried fruit intake was associated with lower kidney function markers, including BUN (β: −0.171, 95% confidence interval (CI): −0.239 to −0.102, p = 1.063 × 10−6), CR (β: −0.205, 95% CI: −0.311 to −0.099, p = 1.455 × 10−4), UA (β = −0.317, 95% CI: −0.384 to −0.249, p = 4.439 × 10−20), and CysC (β = −0.323, 95% CI: −0.384 to −0.249, p = 1.074 × 10−11); however, it was unrelated to hematuria and microalbuminuria. Causality persisted after performing MVMR analysis; however, with the addition of alcohol consumption and smoking as exposure factors, the causality for UA (β = −0.296, 95% CI: −0.523 to −0.068, p = 1.094 × 10−2) and CysC (β = −0.238, 95% CI: −0.465 to −0.011, p = 4.024× 10−2) weakened, while the causality for BUN (β = −0.038, 95% CI: −0.215 to 0.138, p = 6.698 × 10−1) and CR (β = −0.038, 95% CI: −0.431 to 0.046, p = 1.347 × 10−1) disappeared.ConclusionIncreased dried fruit intake was associated with lower kidney function markers (BUN, CR, UA, and CysC) in the absence of smoking and alcohol consumption; however, the causal relationship between dried fruit intake and BUN and CR disappeared in the presence of smoking and alcohol consumption. These results provide a promising avenue for delaying the course of chronic kidney disease.

Association between food security status and dietary patterns in a cohort of first-time food-aid users.

To examine the associations between food security status and dietary patterns among first-time food-aid users. From September 2018 to January 2020, a sample of 1001 newly registered food-aid users from 106 community-based food donation organizations were recruited across urban, rural, and peri-urban areas in four administrative regions of the province of Quebec, Canada. The Household Food Security Survey Module (HFSSM) and the Short Diet Questionnaire (SDQ) were used to assess food security status and food intake, respectively. A posteriori dietary patterns were identified through principal component analysis. Regression analyses were performed on 987 participants with complete data to quantify the association between food security status and dietary patterns. Three main dietary patterns were identified: prudent (intake of fruits and fruit juice, plant-based beverages and legumes, green salad, carrots, other vegetables, whole grains, and fish), western (intake of poultry, red meat, potatoes and fried potatoes, rice, and pasta and refined grains), and snack foods (intake of salty snacks, cheese, butter and margarine, sweets, condiments, sweet beverages, and processed meat). Food insecurity was negatively associated with the prudent dietary pattern and positively associated with the snackfood dietary pattern. This study highlights the complexity of dietary patterns in a vulnerable population of first-time food-aid users, especially among those who are severely food insecure.

Dietary patterns during pregnancy in relation to maternal dietary intake: The Mutaba'ah Study.

To relate adherence to healthy dietary patterns, evaluated by different dietary indices, to the intake of nutrients and food groups among pregnant women in the United Arab Emirates. The analyses included 1122 pregnant women from the Mutaba'ah Study. Dietary intake was assessed using a semi-quantitative Food Frequency Questionnaire. Adherence to three dietary pattern indices was assessed; Alternate Healthy Eating Index for Pregnancy (AHEI-P), Alternate Mediterranean Diet (aMED) and Dietary Approaches to Stop Hypertension (DASH). Associations between adherence (score >median) to the three dietary indices and intake of nutrients and food groups were analyzed using logistic regression analysis. Women with higher intake of polyunsaturated fatty acids, fiber, vegetables, fruits, legumes, and nuts and lower intake of saturated fatty acids, red meat, and sweetened beverages had significantly higher odds of adherence to all three dietary patterns (p<0.05). Associations between intakes of nutrients and food groups with odds of adherence to the dietary patterns differed for total fat (only with AHEI-P, [odds ratio [OR]: 0.96; 95% confidence interval [CI]: 0.94-0.98]) and monounsaturated fatty acids (only with aMED, [OR: 1.06; 95% CI: 1.02-1.10]), dairy (with AHEI-P [OR: 0.89; 95% CI: 0.84-0.95] and aMED [OR: 0.86; 95% CI: 0.81-0.91], and with DASH [OR: 1.10; 95% CI: 1.04-1.17]), whole grain (only with aMED [OR: 2.19; 95% CI: 1.61-2.99] and DASH [OR: 4.27; 95% CI: 3.04-5.99]) and fish (with AHEI-P [OR: 1.36; 95% CI: 1.02-1.80] and aMED [OR: 1.79; 95% CI: 1.35-2.38], and with DASH [OR: 0.67; 95% CI: 0.52-0.86]). Adherence to the three dietary pattern indices was generally associated with a favorable intake of nutrients and food groups. However, the indices captured slightly different aspects of dietary intake. These results show that dietary indices that assess adherence to healthy dietary patterns cannot be used interchangeably.

The Role of Household Social Support and Undermining in Dietary Change.

US adults find it challenging to meet disease prevention dietary recommendations and may participate in interventions to improve dietary quality. Social influences outside of the intervention, including level of social support and undermining of healthy eating in the home, may affect an individual's dietary intake. This secondary analysis examined (1) changes in household social support and undermining of healthy eating across a dietary intervention with household member participation and (2) the relationship between changes in social influences and dietary intake. Adults (N = 62) with low adherence to cancer prevention dietary recommendations recruited from the Philadelphia area participated in a 20-week dietary intervention focused on psychoeducation about NCI dietary recommendations and skills for behavior change. Half of the participants were also randomized to have an adult household member participate in some intervention contacts with them. Participants completed measures of social support and undermining of healthy eating and dietary intake at baseline and post-treatment (20weeks). Fifty-two participants had available data for baseline and post-treatment (i.e., completers). Household social support of healthy eating increased more among participants randomized to have household involvement in the intervention with a medium effect (η2 = .11). Fruit and vegetable intake significantly increased among participants with meaningful increases in household social support with a large effect (η2 = .37). There were no significant interaction effects of change in household undermining and time on change in dietary intake. Dietary interventions with a household support component show promise for improving household social support and may impact magnitude of dietary change.

Cross-sectional associations between fruit and vegetable intake and successful ageing across 6 countries: findings from the WHO Study on global AGEing and adult health (SAGE).

This study develops successful ageing profiles across six low and middle-income countries (LMICs) and examines associations with fruit and vegetable (F&V) intake. A cross-sectional analysis was conducted in mid-aged and older adults from the WHO Study of Global Ageing. Participants without chronic disease, cognitive impairment, depression or disability and with good physical, cardiovascular and respiratory function were considered to have successfully aged. Associations between F&V intake (serves/day) and successful ageing were examined using log-binomial regression adjusting for key confounders. China, Ghana, India, Mexico, Russia and South Africa. A total of 28785 men and women aged aged 50 years and over. Successful ageing ranged from 4% in Mexico to 15% in China. After adjustment, only Ghana showed an association between fruit intake and successful ageing, with an inverse association identified (Prevalence Ratio [PR]=0.87, 95% Confidence Interval [CI]: 0.78-0.98). An inverse association between vegetable intake and successful ageing was found in China (0.97, 0.95-0.98) but no other country. An inverse association was shown for both China (0.98, 0.96-0.99) and Ghana (0.92, 0.84-1.00) when considering fruit and vegetables combined. Associations between F&V intake and successful ageing are inconsistent. Further studies on LMIC countries are needed to meet the challenges of the ageing population.

Comparing the Dietary Habits and the Food Choices Between Italian and Dominican Adult Populations: Focus on Fruit and Vegetable Intakes and Their Association with Skin Carotenoid Levels.

The Mediterranean Diet (MD) is characterized by a high intake of fruits and vegetables (FVs), which is considered as an important contributor to the beneficial effects of the MD pattern. In this cross-sectional study, we compared the food choices, evaluated by dietary habit questionnaires, of a sample of 995 adults, including 601 and 394 participants from Southern Italy and the Dominican Republic, respectively. In addition, we focused on their FV consumption, assessed by the Mediterranean Diet Adherence Screener (MEDAS) questionnaire, and on its association with skin carotenoid levels as measured by the Veggie Meter®. We found that a significantly higher percentage of Italians had five meals/day and breakfast compared to Dominicans (five meals/day: 43 vs. 25, p < 0.05; breakfast: 89 vs. 79, p < 0.05), whereas a lower percentage of participants from Italy consumed snacks between the two meals compared to the Dominican Republic population (47 vs. 70, p < 0.005). Most of the participants from both populations had breakfast at home. However, 59.3% of Italians and 27.5% of Dominicans (p = 0.005) had breakfast between 7:00 and 9:00 a.m., whereas 5.8% and 27.5% (p = 0.001) had breakfast after 9:00 a.m., respectively. Milk/yogurt and eggs were the most consumed foods for breakfast in Italy and the Dominican Republic, respectively. Regarding the main meals, most of the Italians and Dominicans had a first course for lunch and a second course for dinner. Of note, we observed that approximately half of the Italians ate FVs in their main meals and had a higher carotenoid score than the Dominicans. Interestingly, in the multiple linear regression analysis, we found that the carotenoid score was positively associated with sex (β = 0.078; p = 0.009), age (β = 0.008; p = 0.001), vegetable consumption (β = 0.12; p = 0.041) and the perception of a healthy diet (β = 0.12; p = 0.001) in the Dominic Republic population, while the carotenoid score was directly associated with sex (β = 54.97; p < 0.0001) and both vegetable (β = 25.42; p = 0.0008) and fruit (β = 38.61; p < 0.0001) consumption in the Italian sample. Our findings confirm the need to promote nutrition-based interventions to encourage FV intake, particularly in non-Mediterranean countries.

Exploring Dietary Factors and Esophageal Adenocarcinoma: Insights From Mendelian Randomization Study

ABSTRACTEsophageal adenocarcinoma and diet are not well understood to be associated. We conducted Mendelian randomization analysis using 18 dietary factors as exposures (primarily including fruit consumption, vegetable consumption, alcohol consumption, meat consumption, tea intake, fish intake, etc.), with esophageal adenocarcinoma as the outcome. The IVW method was the leading method used for detecting causal links. Cochran's Q test was utilized to assess heterogeneity, the intercept of the MR‐Egger method was used to assess the presence of horizontal pleiotropy, and the existence of outliers was identified via the MR‐Presso method. This study identified that both alcohol intake frequency (OR = 1.375, p = 0.0216) and coffee intake (OR = 2.680, p = 0.0304) were linked to a heightened risk of esophageal adenocarcinoma, while raw vegetable/salad consumption (OR = 0.117, p = 0.0258) and dried fruit intake (OR = 0.229, p = 0.00235) were associated with a decreased risk of esophageal adenocarcinoma. After FDR correction, only dried fruit intake (q = 0.0423) remained statistically significant. However, there was no evidence linking the other 14 dietary variables to esophageal adenocarcinoma. This study observed that alcohol consumption and coffee intake increase the risk of esophageal adenocarcinoma, while the intake of dried fruits rather than fresh fruits and raw vegetable intake rather than cooked vegetable intake reduce the risk of esophageal adenocarcinoma. Other dietary factors were not associated with the risk of esophageal adenocarcinoma.

Characteristics associated with fruit and vegetable consumption in mid aged and older Chinese men and women: a cross-sectional analysis of the first wave of WHO SAGE China.

Adequate fruit and vegetable consumption is essential for healthy ageing and prevention and management of chronic disease. This study aimed to examine characteristics associated with fruit and vegetable consumption in Chinese men and women aged 50 years and over. Data from the first wave of the Chinese cohort (2008-2010) of the WHO's Study on global AGEing and adult health (SAGE) survey was used. Fruit and vegetable consumption was assessed by self-reported typical consumption in serves/day. Characteristics examined were age, education, financial security, home ownership, marital status, social cohesion and rural location. Associations with fruit and vegetable consumption were assessed using multiple linear regression adjusted for confounders and stratified by sex. Overall, women consumed more serves of fruit per day than men (mean (standard deviation): 2·6 (2·2) and 2·2 (2·1) serves/day, respectively) whereas men consumed more serves of vegetables than women (7·2 (4·0) and 6·7 (3·7)). Lower fruit consumption was associated with lower education, lower social participation, income insecurity, renting, being un-partnered and rural residency in men and women, as well as older age in women. Lower vegetable consumption was associated with older age, lower education and urban residency in men and women and lower social participation in men and being unpartnered in women. This study has identified characteristics associated with fruit and vegetable intake in a sample of mid aged and older Chinese men and women. Further research on the interrelationships between these characteristics and fruit and vegetable intake as well as longitudinal relationships is warranted.

Impact of provision of abdominal aortic calcification results on fruit and vegetable intake: 12-week randomized phase 2 controlled trial

Provision of non-invasive vascular imaging results to individuals has been shown to improve cardiovascular disease risk factor control: its impact on diet remains uncertain. In this two-arm, single-blind, parallel, 12-week randomized controlled trial, 240 participants, 57.5% females aged 60–80 y had abdominal aortic calcification and clinical assessments performed at a hospital clinic. Participants were randomized 1:1 to receive (intervention n = 121) or not (control n = 119) their calcification results. Both groups received educational resources on cardiovascular disease risk control and were unblinded to the intervention. Outcome measures were performed at baseline and 12 weeks. The primary outcomes of the study were changes in fruit and vegetable intake measures over 12 weeks assessed using plasma carotenoid concentrations (biomarkers of FV intake) and a food frequency questionnaire. Secondary outcomes included 12-week changes in other aspects of the diet, physical activity, body weight, blood pressure, heart rate, lipid profile, glucose concentrations, estimated cardiovascular disease risk score, and medication use. Between-group differences were tested using linear mixed-effects regression. There were no between-group differences in the primary outcomes at 12 weeks: plasma carotenoids (mean difference +0.03 µg/mL [95%CI −0.06, 0.13]) and fruit and vegetable intakes (+18 g/d [−37, 72]). However, the provision of calcification results led to between-group differences in serum total (−0.22 mmol/L [−0.41, −0.04]) and non-HDL (−0.19 mmol/L [−0.35, −0.03]) cholesterol, and estimated cardiovascular disease risk score (−0.24% [−0.47, −0.02]). No between-group differences were seen for other secondary outcomes. In this work, providing vascular imaging results did not improve diet but did improve some cardiovascular disease risk factors (Australian and New Zealand Clinical Trials Registry ACTRN12618001087246).

Association of dietary patterns with serum uric acid and hyperuricemia in Chinese adults

Objective: To analyze the dietary patterns of Chinese adults and explore the relationship with serum uric acid (SUA) and hyperuricemia (HUA). Methods: A total of 9 358 adults were selected in the 2018 China Health and Nutrition Survey. Dietary intake data were collected by three consecutive 24-hour dietary recalls and weighing method. The social demographic information of the survey subjects was obtained through questionnaire surveys. The dietary patterns were extracted using factor analysis, and the relationship between dietary patterns and SUA was analyzed using multiple linear regression analysis. The correlation between HUA and dietary patterns was analyzed using logistic regression analysis models. Results: Four dietary patterns were identified: northern (high intakes of wheat, other cereals,and tubers); modern (high intakes of fruit, dairy, eggs, and nuts); southern (high intakes of rice and vegetables);animal food-wine (high intake of organ meats, seafood, and wine). The multiple linear regression analysis results showed that the northern pattern was negatively correlated with SUA (β=-0.438, 95%CI: -0.500--0.376); the modern pattern was negatively correlated with SUA (β=-0.134, 95%CI: -0.219--0.049); the southern model was significantly correlated with higher SUA (β=0.146, 95%CI: 0.079-0.214); the animal food-wine pattern was positively correlated with SUA (β=0.188, 95%CI: 0.123-0.252). Logistic regression analysis showed that compared with the northern model score Q1 group, the risk of developing HUA was reduced in Q3 and Q4 groups, with ORs values of 0.777 (95%CI: 0.650-0.929) and 0.509 (95%CI: 0.423-0.613), respectively; and compared with the modern model score Q1 group, the higher the scores in Q3 and Q4 groups, the HUA was lower, with ORs of 0.793 (95%CI: 0.660-0.953) and 0.768 (95%CI: 0.631-0.934), respectively. Compared with the animal food-wine pattern score Q1 group, the risk of developing HUA was increased in both Q3 and Q4 groups (Q3 group: OR=1.224, 95%CI: 1.012-1.480; Q4 group: OR=1.312, 95%CI: 1.086-1.584). Conclusions: Dietary patterns are associated with HUA. The northern and modern patterns are related to lower SUA levels and reduced risk of HUA, while the animal food-wine pattern increases the risk of HUA.
