Mediterranean Diet Adherence and Eating Disorders Screening in Adults with Celiac Disease in Morocco.

Celiac disease is a chronic autoimmune disease of the small intestine, related to gluten intolerance occurring in genetically predisposed patients. This study aimed to evaluate Mediterranean diet adherence, screen eating disorders and establish the relationship between Mediterranean diet and eating disorders. This study included 81 adults with celiac disease, and 85 without celiac disease from Rabat-Sale-Kenitra hospitals between May 2022 and Nov 2022. The Mediterranean Diet Serving Score (MDSS) questionnaire was used to determine adherence to the Mediterranean diet and SCOFF questionnaire was used to screen eating disorders. The results showed a significant difference between the two groups in age (P=0.000), weight (P=0.041), height (P=0.000) and non-adherence to Mediterranean diet (P=0.032). Participants without celiac disease reported a significantly (P=0.032) lower adherence score to the Mediterranean diet (62.35%) than participants with celiac disease (29.62%). Additionally, the results of the Khi2 test which revealed a significant association between MDSS and SCOFF (P=0.024). In addition, based on logistic regression the Mediterranean diet Serving Score was significantly associated with eating disorders (P=0.025) in adults with celiac disease, on the other hand, weight, height, BMI and MDSS were significantly associated with eating disorders in adults without celiac disease. Our study showed good adherence to the Mediterranean diet by celiac adults so it can be assumed that the Mediterranean diet could have a protective effect against eating disorders in celiac patients.

Development and Validation of a Questionnaire to Measure Adherence to a Mediterranean-Type Diet in Youth.

Proper nutrition during childhood is crucial for preventing chronic diseases and ensuring optimal growth. This study aimed to develop and validate the Korean version of the KIDMED (K-KIDMED) questionnaire to accurately measure Mediterranean diet (MD) adherence among Korean children and adolescents. A total of 226 parents, representing their children and adolescents, completed the K-KIDMED, a 112-item food frequency questionnaire (FFQ), and a 24-h dietary recall method through an anonymous online survey. The K-KIDMED comprised 11 questions, with five excluded from the original scoring as they did not apply to the FFQ. Scores were categorized into three levels of adherence to the MD: low (1 or less), average (2-4), and good (5 or more). The agreement between total MD scores from the Korean version of the Mediterranean diet adherence screener and the FFQ was moderate (intraclass correlation coefficient = 0.455, 95% confidence interval: 0.346, 0.553). Among the 226 children and adolescents, 36.7% had low adherence to the KIDMED, 43.3% had intermediate adherence, and 19.9% had good adherence. Higher K-KIDMED scores were correlated with greater intakes of fiber, vitamin K, vitamin B6, and potassium (all p < 0.05). We developed the K-KIDMED as a valid tool to assess MD adherence in Korean children and adolescents.

Cooking and food skills and their relationship with adherence to the Mediterranean diet in young adults attending university: A cross-sectional study from Türkiye.

Adherence to the Mediterranean diet has decreased among university students in many countries. Cooking skills (CS) and food skills (FS) have been suggested as potential targets for reversing this decline. This study aims to determine CS and FS and to examine their relationship with adherence to the Mediterranean diet in young adults attending university in Türkiye. This cross-sectional study was conducted between March 2022 and April 2022 at Ondokuz Mayıs University in Samsun, Türkiye, and included 859 university students (56.1% women; mean age 22.57 ± 2.75 years). Sociodemographic characteristics were collected. The CS and FS measure and the Mediterranean Diet Adherence Screener (MEDAS) were administered. The mean MEDAS, CS and FS scores were 4.77 ± 1.97, 59.10 ± 18.17 and 77.81 ± 22.27, respectively. Those with higher MEDAS scores (quartile three and quartile four-Q3 and Q4) had significantly higher CS scores than those with lower scores (Q1 and Q2), while those in the lowest quartile (Q1) had lower FS scores than all other quartiles (p < 0.001). Total scores of CS and FS positively, although weakly, correlated with MEDAS (r = 0.227 and r = 0.296; p < 0.001). Two separate models for CS and FS were analysed; along with access to kitchen facilities, CS and FS contributed the most variability, accounting for 8.9% and 11.8% of the variance in MEDAS, respectively (p < 0.001). This research indicates that higher CS and FS in university students are associated with higher adherence to the Mediterranean diet. It is also recommended that kitchen facilities be provided for them to practice these skills.

Mediterranean Diet in Older Irish Adults: Prevalence, Patterns, Predictors and Pertinence.

The Mediterranean diet (MD) shows the strongest evidence in support of healthy aging and prevention of age-related diseases. It is associated with a decreased risk of chronic disease, such as cardiovascular disease, obesity, hypertension, diabetes mellitus and cognitive disease. Given the health-promoting aspects of this diet, we conducted a secondary analysis of data from the LifeAge study ("Promoting the shift: sedentary Lifestyle towards active Ageing-LifeAge" Project No 603121-EPP-1-2018-1-ES-SPO-SCP) with the primary aim to determine the proportion of older Irish adults adhering to the MD and to examine the association between adherence to the MD (assessed using the Mediterranean Diet Adherence Screener (MEDAS) scoring tool) and anthropometric risk factors of non-communicable diseases. Of the 131 eligible participants (71.8% female, n = 94) (medically well, aged > 50 years and physically independent) (mean age = 66.2 ± 6.5 years), the mean cumulative MD score across the cohort was 5.8 ± 2.2, with 41% classified as moderate-to-high MD adherers (scoring > 7 MEDAS). Females had a significantly higher score compared to males (female 6.24 ± 1.98; male 4.86 ± 2.53; p = 0.002). Age (y), waist circumference (cm) and waist-hip ratio (WHR) each had a significant (p < 0.05) weak and negative correlation with MD score (r = -0.193, -0.240, -0.284, respectively). Visceral fat level had a significant (p < 0.05) moderate and negative correlation with MD score (r = -0.327). This analysis is the first to assess adherence to the MD in older Irish adults. MD adherence was lower in the Irish older cohort than that reported in older adults in Mediterranean regions and was adhered to more by females and those with a more favourable anthropometric profile. The health-promoting aspects of the diet are evident in non-Mediterranean regions as is demonstrated by the lesser incidence of some non-communicable diseases in moderate-to-high adherers. With the evidence of the protective effects of the MD, external to Mediterranean regions, it would be helpful to establish limitations to adherence, especially in aging populations living in non-Mediterranean regions.

The Relationship between Healthy Vascular Aging with the Mediterranean Diet and Other Lifestyles in the Spanish Population: The EVA Study.

In this cross-sectional descriptive study, 501 individuals aged 35 to 75 years were recruited from five health centers by random sampling stratified by age and sex (55.90 ± 14.24 years, 49.70% men). HVA was determined in two steps. Step 1: Subjects with vascular damage to the carotid arteries or peripheral arterial disease were classified as non-HVA. Step 2: The study population was classified by age and sex using the percentiles of the vascular aging index (VAI), with VAI ≤p25 considered HVA and >p25 considered non-HVA. The VAI was estimated using the following formula (VAI = (log (1.09) × 10 cIMT + log (1.14) cfPWV) × 39.1 + 4.76. Carotid-femoral pulse wave velocity (cfPWV) was measured with the SphygmoCor® device, and carotid intima-media thickness using Sonosite Micromax® ultrasound. Mediterranean diet (MD) adherence, alcohol and tobacco use were recorded through validated questionnaires. Physical activity was assessed with the ActiGraph-GT3X® accelerometer. The mean VAI value was 61.23 ± 12.86 (men-63.47 ± 13.75 and women-59.04 ± 11.54; p < 0.001). HVA was found in 18.9% (men-19.9% and women-17.8%). In the multiple regression analysis after adjusting for possible confounding factors, the mean VAI value showed a positive association with alcohol use (β = 0.020) and sedentary hours per week (β = 0.109) and a negative association with hours of activity per week (β = -0.102) and with the number of healthy lifestyles (β = -0.640). In the logistic regression analysis, after adjusting for possible confounding factors and compared to those classified as non-HVA, subjects classified as HVA were more likely to show MD adherence (OR = 0.571), do more than 26 h per week of physical activity (OR = 1.735), spend under 142 h per week being sedentary (OR = 1.696), and have more than two healthy lifestyles (OR = 1.877). The results of this study suggest that the more time spent doing physical activity and the less time spent in a sedentary state, the lower the vascular aging index and the greater the likelihood of being classified in the group of subjects with HVA.

Mediterranean Diet Adherence beyond Boundaries: Sociodemographic and Pregnancy-Related Determinants among Saudi Women.

Although the expected benefits of the Mediterranean diet (MD) are comprehensive, its implementation is hampered by poor adherence. Several factors can affect adherence to MD guidelines. The current study aimed to explore sociodemographic and pregnancy-related determinants of MD adherence among Saudi women. A correlational cross-sectional research design was conducted on a snowball sample of 774 pregnant women from the Najran region, Saudi Arabia, using an online survey between February and May 2024. A self-administered questionnaire consisting of sociodemographic data, pregnancy-related characteristics, and the MD scale was used for data collection. The current study showed that only 32.2% of participants had high adherence to the MD, and 57.6% had moderate adherence. Regarding sociodemographic determinants of MD adherence, highly educated, older women with lower pre-pregnancy body mass index (BMI) and higher monthly income increased the probability of high adherence to the MD (p < 0.05). In addition, being physically active before or during pregnancy significantly increased the woman's probability of having higher adherence to the MD (p < 0.05). Concerning pregnancy-related determinants, having a planned pregnancy and regular antenatal care (ANC) increased the woman's probability of high adherence to the MD by nearly 1.3 times (p < 0.05). In addition, low adherence to the MD increases the risk of gestational diabetes. In conclusion, numerous sociodemographic and pregnancy-related determinacies can significantly affect a woman's adherence to the MD. Healthcare providers should address these determinants during the planning and implementation of pregnant women's nutritional counseling to make the counseling process woman-centered and more effective.

The Mediterranean diet and periodontitis: A systematic review and meta-analysis

Periodontitis is a severe oral health condition that affects the soft tissue and bone supporting the teeth. The Mediterranean diet has been proposed as a potential contributor to reducing the risk of periodontitis. This systematic review and meta-analysis aims to explore the association between adherence to the Mediterranean diet and periodontitis. A comprehensive literature search from 1992 to January 2024 was conducted across multiple databases, including PubMed, Scopus, Web of Science, and Google Scholar. The included studies were clinical trials, randomized controlled trials, and observational studies that evaluated the impact of the Mediterranean diet on periodontitis. Data extraction and quality assessment of the included studies were performed using standardized protocols. A meta-analysis was conducted to combine effect sizes from multiple studies. This review included seven studies, comprising one cohort study, five cross-sectional studies, and one randomized controlled trial. While some studies reported a potential link between Mediterranean diet adherence and periodontitis, the overall analysis did not demonstrate a significant association. The meta-analysis revealed an Odds Ratio (95 % Confidence Interval) of 0.77 (0.58, 1.03) for the association between adherence to the Mediterranean diet and periodontitis (p = 0.08). This systematic review and meta-analysis found no statistically significant association between periodontitis and Mediterranean diet adherence. Future research should prioritize the implementation of rigorous clinical studies with longer follow-up periods to better understand the causal association between the Mediterranean diet and periodontitis. Observational studies with larger sample sizes are needed to establish more conclusive evidence regarding the impact of dietary patterns on periodontal health.

Exploring the relationship between Mediterranean diet adherence, interoceptive-like eating behaviours, and weight status: a cross-sectional study

Exploring the relationship between Mediterranean diet adherence, interoceptive-like eating behaviours, and weight status: a cross-sectional study

Combination of Machine Learning Techniques to Predict Overweight/Obesity in Adults.

(1) Background: Artificial intelligence using machine learning techniques may help us to predict and prevent obesity. The aim was to design an interpretable prediction algorithm for overweight/obesity risk based on a combination of different machine learning techniques. (2) Methods: 38 variables related to sociodemographic, lifestyle, and health aspects from 1179 residents in Madrid were collected and used to train predictive models. Accuracy, precision, and recall metrics were tested and compared between nine classical machine learning techniques and the predictive model based on a combination of those classical machine learning techniques. Statistical validation was performed. The shapely additive explanation technique was used to identify the variables with the greatest impact on weight gain. (3) Results: Cascade classifier model combining gradient boosting, random forest, and logistic regression models showed the best predictive results for overweight/obesity compared to all machine learning techniques tested, reaching an accuracy of 79%, precision of 84%, and recall of 89% for predictions for weight gain. Age, sex, academic level, profession, smoking habits, wine consumption, and Mediterranean diet adherence had the highest impact on predicting obesity. (4) Conclusions: A combination of machine learning techniques showed a significant improvement in accuracy to predict risk of overweight/obesity than machine learning techniques separately.

Association between Mediterranean Diet and Advanced Glycation End Products in University Students: A Cross-Sectional Study.

The aim of this study was to evaluate the association between the Mediterranean diet (MD) and the accumulation of advanced glycation end products (AGEs) measured by skin autofluorescence. This cross-sectional study included 1016 healthy students from the University of Split, Croatia. Participants completed a self-administered questionnaire. Adherence to the MD was assessed using the Mediterranean Diet Serving Score (MDSS), and tissue AGEs accumulation was measured using the AGE Reader mu (DiagnOptics). Multivariate linear regression was used in the analysis. Students' age and female gender were associated with higher levels of AGEs, which was likewise found for greater coffee intake, adequate olive oil consumption, smoking, and lower levels of physical activity. Higher consummation of vegetables and eating breakfast regularly were associated with lower AGEs levels. The overall MD adherence was not associated with AGEs, possibly due to very low overall compliance to the MD principles among students (8.3% in women and 3.8% in men). Health perception was positively associated with the MD and nonsmoking and negatively with the perceived stress level, while AGEs did not show significant association with self-rated students' health. These results indicate that various lifestyle habits are associated with AGEs accumulation even in young and generally healthy people. Hence, health promotion and preventive measures are necessary from an early age.

Workplace Health Promotion in Italian University Employees: Effects on Body Composition and Mediterranean Diet Adherence.

As Workplace Health Promotion is spreading among several working environments, the university context seems to be one of the best to apply primary prevention activities. Working in this direction, the University of Torino led the Wellness@Work for UniTo Project (W@W), with the aim of promoting employees' health. Internal university professionals assessed body composition and adherence to the Mediterranean diet (MD), giving on-target advice for improving lifestyle. The aim of this paper is to evaluate the effectiveness of the W@W Project after a 4-month intervention period. This project was addressed to university employees, who could participate on a voluntary basis. Researchers assessed (T1) socio-demographic information and collected anthropometric variables. Body composition was evaluated through Classic and Specific Bioelectrical impedance Vector Analysis (BIVA). Adherence to the MD was assessed through the Medi-Lite questionnaire. After the assessments, participants were given 5-min counselling from internal professionals. After about 4 months, participants were supposed to undergo same assessments (T2). Overall, 479 workers joined the project, and of those, 246 came back for the T2 assessment. Globally, either anthropometric, body composition, or MD variables improved significantly after 4 months, both for male and female samples, suggesting how an easy-to-apply WHP intervention could help to improve workers' health.

Italian and Middle Eastern adherence to Mediterranean diet in relation to Body Mass Index and non-communicable diseases: nutritional adequacy of simulated weekly food plans

BackgroundThe Mediterranean diet (MD), known to prevent obesity, overweight and the related non communicable diseases (NCD), is based on typical dishes, foods and on a common cultural milieu. Although MD is the basis of dietary guidelines, the prevalence of obesity, overweight and NCD, is increasing both in Western regions, and even more in Middle Eastern regions (MER). This study aimed to analyze (i) the impact of different levels of adherence to the MD, in Italy and MER, on body mass index (BMI) (ii) the bromatological composition of a simulated 7-days food plan (7-DFP) based on Italian or MER typical meals, following MD criteria and the Italian or MER food base dietary guideline; (iii) the optimization of nutrients impacting on NCD.MethodsThe 7-DFPs were implemented using a dietary software. The association between adherence to MD and BMI was evaluated by pooled estimated ORs (with 95% confidence intervals and p-values). Pooled measures were obtained by the methods appropriate for meta-analysis. The different food-based guidelines have been compared.ResultsThe pooled ORs of obese status comparing medium vs. high adherence to MD were: 1.19 (95% C.I.: 0.99; 1.42, p-value = 0.062) and 1.12 (95% C.I.: 0.90; 1.38, p-value = 0.311) for MER and Italy respectively. For the comparison of low vs. high adherence, the pooled ORs were 1.05 (95% C.I.: 0.88; 1.24, p-value = 0.598) for MER, and 1.20 (95% C.I.: 1.02; 1.41, p-value = 0.031) for Italy when outliers are removed. High adherence to the MD resulted as potential protective factor against obesity. In MER 7-DFP: total fats is higher (34.5 E%) vs. Italian 7-DFP (29.4 E%); EPA (20 mg) and DHA (40 mg) are lower than recommended (200 mg each); sugars (12.6 E%) are higher than recommended (< 10 E%). Calcium, Zinc, and vitamin D do not reach target values in both 7-DFPs.ConclusionThis study highlights that, even when 7-DFPs follow MD and refer to nutrient needs, it is necessary to verify nutrient excesses or deficits impacting on NCD. High MD adherence is protective toward NCDs. MD principles, and energy balance should be communicated according to socioeconomic and educational levels.

Maternal pre-pregnancy diet and prenatal depression: the mediating role of pre-pregnancy weight status and prenatal inflammation.

Depression is a common prenatal psychological complication. We aimed to investigate if maternal pre-pregnancy diet can impact prenatal depressive symptoms and the mediating role of pre-pregnancy BMI and inflammation. We used data (N 1141) from the Alberta Pregnancy Outcomes and Nutrition cohort study. We calculated Mediterranean diet adherence (MED) and dietary inflammatory index (DII) scores using data from pre-pregnancy FFQ. In the third-trimester, we assessed depressive symptoms using Edinburgh Postpartum Depression Scale (EPDS) and inflammation through serum C-reactive protein (CRP) levels. BMI was calculated from self-reported pre-pregnancy weight. Race-stratified analyses (white and people of colour) were run. We observed no association between MED or DII tertiles and depressive symptoms. However, white participants in the MED tertile-3 had lower risk of depression (EPDS < 10) compared with tertile-1 (OR = 0·56, 95 % CI, 0·33, 0·95). White individuals in MED tertile-3 had lower BMI (MD = -1·08; 95 % CI, -1·77, -0·39) and CRP (MD = -0·53; 95 % CI, -0·95, -0·11) than tertile-1, and those in DII tertile-2 (MD = 0·44; 95 % CI, 0·03, 0·84) and tertile-3 (MD = 0·42; 95 % CI, 0·01, 0·83) had higher CRP than tertile-1. Among people of colour, neither MED nor DII was associated with BMI or CRP, but BMI was negatively associated with depressive symptoms (β = -0·25, 95 % CI, -0·43, -0·06). We found no association between diet and depressive symptoms through BMI or CRP, in either race. Pre-pregnancy diet might affect the risk of prenatal depression in a race-specific way. Further research is required to explore the racial differences in the association between maternal diet and prenatal depressive symptoms/depression risk.

Drivers and Barriers Influencing Adherence to the Mediterranean Diet: A Comparative Study across Five Countries.

Given the global decline in adherence to the Mediterranean Diet (MD), even within its native region, it is key to identify the factors influencing this trend to mitigate the negative health outcomes associated with westernized diets. To this end, 4025 individuals (49.6% women, 42.6 ± 14.2 y/o) from Greece, Italy, Morocco, Slovenia, and Tunisia remotely completed a series of measures assessing motives, attitudes, and psychosocial factors related to MD adherence, which was evaluated using the MEDAS questionnaire. The results suggested medium-to-low adherence across all countries, with the highest adherence in Italy and Morocco and the lowest in Slovenia. Structural equation modeling revealed that positive attitudes toward the healthiness of food were the strongest predictors of adherence, whereas picky eating was a significant negative predictor in all countries except Greece. Adherence to the MD was positively influenced by health motivations in Morocco and weight control in Slovenia and Greece, while sensory appeal negatively influenced adherence in Italy. Additionally, price and convenience were significant barriers in Tunisia and Greece, whereas a preference for local and seasonal foods promoted adherence in Morocco and Greece. Overall, our findings underscore the need for country-specific interventions and policies that address distinct local factors and motivations to ease favorable shifts in dietary patterns toward MD principles.

Adherence to a Mediterranean-style diet and severity of menopausal symptoms in perimenopausal and menopausal women from Australia: a cross-sectional analysis

PurposeTo explore the independent associations between adherence to a Mediterranean-style diet and severity of menopausal symptoms in perimenopausal and menopausal women living in Australia.MethodsDietary adherence was assessed using the Mediterranean Diet Adherence Screener (MEDAS), the Menopause Rating Scale (MRS) was used to assess the severity of menopausal symptoms, and the 36-item short form survey instrument (SF-36) was used to assess health-related quality of life (HRQoL).ResultsA total of n = 207 participants (50.7 ± 4.3 years; BMI: 28.0 ± 7.4 kg/m2) were included in the final analyses. Participants reported low-moderate adherence to a Mediterranean-style diet (5.2 ± 1.8; range: 1–11). Adherence was not associated with severity of menopausal symptoms. However, low consumption of sugar-sweetened beverages was inversely associated with joint and muscle complaints, independent of all covariates (β = -0.149; CI: -0.118, -0.022; P = 0.042). Adherence to a Mediterranean-style diet was positively associated with the physical function subscale of HRQoL (β = 0.173, CI: 0.001, 0.029; P = 0.031) and a low intake of red and processed meat was positively associated with the general health subscale (β = 0.296, CI: 0.005, 0.014; P = < 0.001).ConclusionDiet quality may be related to severity of menopausal symptoms and HRQoL in perimenopausal and menopausal women. However, exploration of these findings using longitudinal analyses and robust clinical trials are needed to better elucidate these findings.

Poor Adherence to the Mediterranean Diet and Sleep Disturbances Are Associated with Migraine Chronification and Disability among an Adult Population in the Lazio Region, Italy.

Lifestyle factors, such as diet and sleep quality, are receiving increasing interest as accessible therapeutic approaches to migraine. The Mediterranean diet (MD) has shown clear benefits in cardiovascular and metabolic diseases, as well as in sleep patterns. Here, our objective was to identify the impact of adherence to the MD and other lifestyle factors on the clinical burden of migraine. For this purpose, we enrolled 170 migraine patients and 100 controls, assessing the clinical disability of headache using standardized clinical scales (HIT-6 and MIDAS) in the migraineur cohort and lifestyle patterns in both groups through the PREDIMED score for MD adherence, the IPAQ scale for physical activity, and BMI. Subjects were also screened for sleep-wake disturbances based on the Pittsburgh Sleep Quality Index (PSQI). We found that migraine patients had lower adherence to the MD compared to the controls and that the HIT-6 scale had a significant negative relationship with MD adherence in patients with high-frequency episodic and chronic migraine. Additionally, in the same migraine patients, the presence of sleep-wake disturbances was correlated with greater migraine disability as assessed by the MIDAS score. In conclusion, this study found that among different lifestyle factors, poor adherence to the MD and the presence of sleep-wake disturbances were closely associated with migraine disability and chronification.

Exploring the Association between Mediterranean Diet Adherence and Arterial Stiffness in Healthy Adults: Findings from the EvasCu Study.

(1) Background: Previous evidence has indicated a connection between a Mediterranean diet and cardiovascular disease. However, evidence for subclinical markers of cardiovascular disease, such as arterial stiffness, is limited. Therefore, the aim of this study was to assess the associations between adherence to the Mediterranean diet (MD), as assessed by the MEDAS-14 questionnaire, and arterial stiffness, as assessed by aortic pulse wave velocity, in healthy adults and according to sex. (2) A cross-sectional study including 386 healthy participants was performed in the EVasCu study. Adjusted and unadjusted differences in adherence to the MD and arterial stiffness were determined using Student's t test and ANCOVA for the total sample and according to sex. (3) Results: Our results showed that individuals with a high adherence to the MD had a greater arterial stiffness, both in the total sample and in females, although this difference was not significant after adjusting for possible confounding variables, such as age. (4) Conclusions: Our findings indicated that, in the unadjusted analyses, healthy subjects with a high adherence to the MD showed a greater arterial stiffness. When these analyses were adjusted, no significant differences were shown in a-PWv according to the categories of MD adherence.

Exploring culinary diversity to enhance Mediterranean diet adherence: A randomized controlled trial

We Investigated how promoting diverse, healthy food options affects long-term dietary choices. We hypothesized that encouraging exploration of nutritious plant-based foods would lead to lasting improvements in diet. Participants (N = 211) were randomly assigned into two groups for a 6-week intervention: The fixed menu group was given the same large menu every week, while the changing menu group received a new small menu each week. At the end of the intervention both groups were exposed to the same menu suggestions. Food diversity evaluation was based on weekly reports collected during the intervention. Self-reported adherence to Mediterranean diet components was assessed using the I-MEDAS screener. The proportion of plant-based foods in participants' diets was estimated using a 0–100% scale based on self-report. Both items were evaluated using online questionnaires given to participants at baseline, at the end of the intervention, as well as three and six months after the intervention concluded. Results mean(SD) demonstrated that participants in fixed menu group explored a significantly wider array of items 26.33(11.64) than those in the changing menus group [19.79(10.29), t(202) = 4.25, p < 0.001, Cohen's d = 0.60]. A repeated measures analysis of covariance rmANCOVA revealed that short-term increase in I-MEDAS and PBD score were noted in both groups; however, only participants with the fixed menu sustained this increase at months follow-up [diff = 1.50, t(132) = 4.50, p < 0.001 Our findings suggest that manipulating the rate of exposure to food suggestions may affect overall dietary variety. It seems that early presentation with options may increase overall dietary variety and may even support longer-term habits. This study contributes to developing effective interventions and highlights the challenge of promoting exploratory behavior in nutrition.

Following Through: The Impact of Culinary Medicine on Mediterranean Diet Uptake in Inflammatory Bowel Disease.

The Mediterranean diet (MD) is recommended for all patients with inflammatory bowel disease (IBD) unless there is a specific contraindication. Culinary medicine has emerged as a method for improving dietary education. Patients and caregivers are often invested in making dietary changes to improve disease control. Here, we examine the dietary preferences of a group of young people with IBD and apply culinary medicine techniques with an in-person MD-focused cooking class. A survey evaluating dietary attitudes was sent to an IBD email listserv at our tertiary care center (n = 779). A validated questionnaire, the Mediterranean Diet Quality Index for Children and Adolescents was used to assess MD adherence. IBD dietitians customized 2 in-person MD-focused cooking classes, one for children 6 to 12 years of age (arm 1) and one for adolescents 13 to 17 years of age (arm 2). Baseline, 1-month follow-up, and 3-month follow-up surveys were completed. There were 112 survey responses. Participants were 67.0% male with diagnosis of Crohn's disease (50.0%), ulcerative colitis (42.0%), or IBD unclassified (8.0%). Most were managed on advanced therapies (82.0%). Most reported making decisions about diet (82.0%) in order to help with IBD, had met with a dietitian (69.0%), and were interested in learning more about the MD (55.3%). MD scores were primarily in the average (49.5%) and poor (41.1%) diet categories. Only those eating together as a family 3 or more times per week or those who had met with a dietitian scored in the optimal diet category. The median MD score at baseline was 4.5, increasing to 6.0 at 1 month and 7.0 at 3 months postintervention. Almost all (90%) would recommend cooking classes to others. Common barriers to MD uptake included lack of knowledge about which foods to prepare, concern about taste, and time to prepare food. This study showcases high patient and caregiver interest in dietary management of IBD and demonstrates efficacy of education via application of culinary medicine. Classes were well received by families and MD adherence scores increased postintervention. As patients with IBD and their families are often motivated to incorporate dietary therapy into their care, this work highlights the role of culinary medicine and value of future study.

Nutrition guidance within a multimodal intervention improves diet quality in prodromal Alzheimer’s disease: Multimodal Preventive Trial for Alzheimer’s Disease (MIND-ADmini)

BackgroundMultimodal lifestyle interventions can benefit overall health, including cognition, in populations at-risk for dementia. However, little is known about the effect of lifestyle interventions in patients with prodromal Alzheimer’s disease (AD). Even less is known about dietary intake and adherence to dietary recommendations within this population making it difficult to design tailored interventions for them.MethodA 6-month MIND-ADmini pilot randomized controlled trial (RCT) was conducted among 93 participants with prodromal AD in Sweden, Finland, Germany, and France. Three arms were included in the RCT: 1) multimodal lifestyle intervention (nutritional guidance, exercise, cognitive training, vascular/metabolic risk management, and social stimulation); 2) multimodal lifestyle intervention + medical food product; and 3) regular health advice (control group). Adherence to dietary advice was assessed with a brief food intake questionnaire by using the Healthy Diet Index (HDI) and Mediterranean Diet Adherence Screener (MEDAS). The intake of macro- and micronutrients were analyzed on a subsample using 3-day food records.ResultsThe dietary quality in the intervention groups, pooled together, improved compared to that of the control group at the end of the study, as measured with by HDI (p = 0.026) and MEDAS (p = 0.008). The lifestyle-only group improved significantly more in MEDAS (p = 0.046) and almost significantly in HDI (p = 0.052) compared to the control group, while the lifestyle + medical food group improved in both HDI (p = 0.042) and MEDAS (p = 0.007) during the study. There were no changes in macro- or micronutrient intake for the intervention groups at follow-up; however, the intakes in the control group declined in several vitamins and minerals when adjusted for energy intake.ConclusionThese results suggest that dietary intervention as part of multimodal lifestyle interventions is feasible and results in improved dietary quality in a population with prodromal AD. Nutrient intakes remained unchanged in the intervention groups while the control group showed a decreasing nutrient density.Trial registrationClinicalTrials.gov NCT03249688, 2017–07-08.
