Abstract
The Mediterranean diet (MD) is one of the healthiest and most sustainable food regimes. Nevertheless, MD diffusion is still limited, emphasizing the need to understand the psychosocial factors that could predict and promote its adoption. Starting from an integrated model of Theory of Planned Behavior (TPB) and Self-Determination Theory (SDT), the present randomized controlled trial investigated the effect of manipulating motivation (autonomous vs. controlled) on intention and MD adherence behavior. Participants included 726 Italian adults randomly allocated to one of three conditions: autonomous motivation manipulation, controlled motivation manipulation, and control group. TPB variables were measured immediately after manipulation (T1), while MD adherence was evaluated 2 weeks later (T2). Results from multivariate analyses of variance highlighted that participants in the autonomous motivation condition reported higher intention and a more favorable cognitive attitude than control group participants. However, no change in behavior was found. Moreover, a path analysis with mediation effect showed that the impact of autonomous motivation condition versus control group on intention was mediated by cognitive attitude. Findings support the integration of TPB and SDT to encourage intention to adhere to the MD, also suggesting that prompting autonomous motivation may help to promote a greater diffusion of this healthy and sustainable dietary pattern.

Abstract
INTRODUCTION Epidemiologic studies relating health outcomes to dietary patterns captured by diet quality indices have shown better quality scores associated with lower mortality and chronic disease incidence. However, changing chronic disease risk factors only alters population health over time, and initial diet quality systematically varies across the population by sociodemographic status. This study uses microsimulation to examine 30-year impacts of improved diet quality by sociodemographic group. METHODS Diet quality across 12 sex-, race/ethnicity-, and education-defined subgroups was estimated from the 2011-2012 National Health and Nutrition Examination Survey. In 2021, the Future Adults (dynamic microsimulation) Model was used to simulate population health and economic outcomes over 30 years for these subgroups and all adults. The modeled pathway was through lowering risk for heart disease by following U.S. Dietary Guidelines. RESULTS Diet quality varied across the sociodemographic subgroups, and half of U.S. adults had diet quality that would be classified as poor. Improving U.S. diet quality to that reported for the top 20% in 2 large health professionals' samples could reduce incidence of heart disease by 9.9% (7.6%-13.8% across the 12 sociodemographic groups) after 30 years. Year 30 would also have 37,000 fewer deaths, 694,000 more quality-adjusted life years, and healthcare cost savings of $59.6 billion (2019 U.S. dollars). CONCLUSIONS Dynamic microsimulation enables predictions of socially important outcomes of prevention efforts, most of which are many years in the future and beyond the scope of trials. This paper estimates the 30-year population health and economic impact of poor diet quality by sociodemographic group.

Abstract
Background. Healthy diet represents one of the largest single modifiable risk factors proven to decrease rates of obesity and associated chronic disease, but practical approaches to improving dietary habits through nutritional intervention are limited. Objective. To evaluate the effectiveness of a medical student-led, 6-week culinary course on participants' dietary knowledge and behaviors, particularly focusing on the tenets of the Mediterranean diet (MedDiet). Design. This study is a prospective multisite cohort study evaluating the effects of a 6-week, hands-on community culinary education course offered at 3 sites. Participants' knowledge of cooking skills, eating habits, and adherence to the MedDiet were evaluated using a survey prior to beginning and 6 weeks after the completion of the course. Analysis was conducted using multivariable regression to assess subjects' diets, associated behaviors, and nutrition beliefs according to the number of classes to which they were exposed (0 to >6). Statistical results were then compared with the machine learning results to check statistical validity after selection of the top-performing algorithm from 43 supervised algorithms using 10-fold cross-validation with performance assessed according to accuracy, root relative square error, and root mean square error. Results. Among the 1381 participants, cooking classes significantly improved patients' overall 9-point MedDiet adherence (β = 0.62, 95% CI 0.23-1.00, P = .002). Participants were more likely to meet MedDiet point requirements for fruit intake (odds ratio [OR] 2.77, 95% CI 1.46-5.23, P = .002), vegetable intake (OR 4.61, 95% CI 1.85-11.53, P = .001), legume intake (OR 2.48, 95% CI 1.45-4.26, P = .001), and olive oil use (OR 2.87, 95% CI 1.44-5.74, P = .003), and were less likely to believe that cooking takes excessive time (OR 0.31, 95% CI 0.16-0.59, P < .001). Conclusion. Hands-on culinary education courses were associated with increased MedDiet adherence and improved knowledge of healthful eating. Such interventions thus represent a cost-effective option for addressing rates of obesity and obesity-related chronic illness.

Maintaining, Managing, and Tele-Monitoring a Nutritionally Adequate Mediterranean Gluten-Free Diet and Proper Lifestyle in Adult Patients. APPLIED SCIENCES-BASEL 2022.

Abstract
The gluten-free diet (GFD) is a restrictive diet. In many cases, it must be permanent and strict, and it may be associated with both nutritional deficiencies and excesses, which can be prevented by following a healthy, natural Mediterranean GFD (Med-GFD). In this paper, we describe the importance of the Mediterranean diet, the correct intake of vitamins and minerals, and how they may play an important protective role against chronic or degenerative conditions. Herewith, we analyze different aspects that influence the ability to maintain a correct and balanced Med-GFD, which may contribute to the health status of patients, including a conscious use of gluten-free products to maintain a healthy lifestyle. Monitoring the Med-GFD remains a pivotal issue: to evaluate the presence of gluten peptides in urine, it could be important to introduce point-of-care testing, an efficient method for GFD self-monitoring (immunochromatographic technique), together with online nutritional questionnaires. Indeed, medical care via telemedicine can provide practical indications aimed at supporting patients and doctors. A natural Med-GFD can ensure the correct intake of nutrients and could be important for patients affected by gluten-related disorders, helping them to maintain a correct and healthy lifestyle.

Abstract
OBJECTIVE Diets closer aligned with nutritional guidelines could lower the risk of several chronic conditions and improve economic outcomes, such as employment and healthcare costs. However, little is known about the range, order of magnitude and timing of these potential effects. DESIGN We used a microsimulation approach to predict US population changes over 30 years in health and economic outcomes that could result from a substantial (but not impossible) improvement in diet quality - an improvement from the third to the fifth quintile of US scores on the Alternate Healthy Eating Index, 2010 version. SETTING Risk ratios from the literature for diabetes, heart disease and stroke were used to modify the Future Adult Model (FAM) to simulate outcomes from a higher-quality diet. Model parameter uncertainty was assessed using bootstrap and sensitivity analysis examined the variation in published risk ratios. PARTICIPANTS FAM simulates outcomes for the US adult population aged 25 and older. RESULTS Improved diet quality initially leads to very small changes in chronic disease prevalence, but these accumulate over time. If diets improved beginning in 2019, after 30 years diabetes prevalence could be reduced by 5·9 million cases (11·5 %), heart disease prevalence by 4·0 million cases (7·2 %) and stroke prevalence by 1·9 million cases (10·3 %). These reductions in disease prevalence would be accompanied that same year by fewer deaths (88 000) and healthcare cost savings of $144·0 billion (2019 USD). CONCLUSIONS This microsimulation study suggests that improvements in diet are likely to improve health and economic population outcomes over time.

Abstract
CONTEXT In recent decades, obesity and type 2 diabetes mellitus (T2DM) have both become global epidemics associated with substantial healthcare needs and costs. OBJECTIVE The aim of this review was to critically assess nutritional interventions for their impact on healthcare costs to community-dwelling individuals regarding T2DM or obesity or both, specifically using CHEERS (Consolidated Health Economic Evaluation Reporting Standards) criteria to assess the economic components of the evidence. DATA SOURCES Searches were executed in Embase, EconLit, AgEcon, PubMed, and Web of Science databases. STUDY SELECTION Studies were included if they had a nutritional perspective, reported an economic evaluation that included healthcare costs, and focused on obesity or T2DM or both. Studies were excluded if they examined clinical nutritional preparations, dietary supplements, industrially modified dietary components, micronutrient deficiencies, or undernutrition; if they did not report the isolated impact of nutrition in complex or lifestyle interventions; or if they were conducted in animals or attempted to transfer findings from animals to humans. DATA EXTRACTION A systematic review was performed according to PRISMA guidelines. Using predefined search terms, 21 studies evaluating food habit interventions or taxation of unhealthy foods and beverages were extracted and evaluated using CHEERS criteria. RESULTS Overall, these studies showed that nutrition interventions and taxation approaches could lead to cost savings and improved health outcomes when compared with current practice. All of the included studies used external sources and economic modeling or risk estimations with population-attributable risks to calculate economic outcomes. CONCLUSIONS Most evidence supported taxation approaches. The effect of nutritional interventions has not been adequately assessed. Controlled studies to directly measure economic impacts are warranted.

Abstract
Background By design, existing scenario-based nutrition economics studies on the financial benefits of healthy dietary behaviors generally report uncertainty in inputs and wide ranges of outcome estimates. Objectives This modeling exercise aimed to establish precision in prediction of the potential healthcare cost savings that would follow a reduction in the incidence of cardiovascular disease (CVD) consistent with an increase in adherence to a Mediterranean-style diet (MedDiet). Design Using a Monte Carlo simulation model on a cost-of-illness analysis assessing MedDiet adherence, CVD incidence reduction, and healthcare cost savings in the United States and Canada, short- and long-term cost savings that are likely to accrue to the American and Canadian healthcare systems were estimated using 20 and 80% increases in MedDiet adherence scenarios. Results Increasing percentage of population adhering to a MedDiet by 20% beyond the current adherence level produced annual savings in CVD-related costs of US$8.2 billion (95% confidence interval [CI], $7.5-$8.8 billion) in the United States and Can$0.32 billion (95% CI, $0.29-$0.34 billion) in Canada. An 80% increase in adherence resulted in savings equal to US$31 billion (95% CI, $28.6-$33.3 billion) and Can$1.2 billion (95% CI, $1.11-$1.30 billion) in each respective country. Conclusion Computational techniques with stochastic parameter inputs, such as the Monte Carlo simulation, could be an effective way of incorporating variability of modeling parameters in nutrition economics studies for improved precision in estimating the monetary value of healthy eating habits.

Abstract
High cost of healthy foods could be a barrier to healthy eating. We aimed to examine the association between dietary cost and adherence to the Mediterranean diet in a non-Mediterranean country. We evaluated cross-sectional data from 12 417 adults in the UK Fenland Study. Responses to 130-item FFQ were used to calculate a Mediterranean diet score (MDS). Dietary cost was estimated by matching food consumption data with retail prices of five major supermarkets. Using multivariable-adjusted linear regression, we examined the association of MDS and individual foods with dietary cost in absolute and relative scales. Subsequently, we assessed how much the association was explained by education, income, marital status and occupation, by conducting mediation analysis and testing interaction by these variables. High compared with low MDS (top to bottom third) was associated with marginally higher cost by 5·4 % (95 % CI 4·4, 6·4) or £0·20/d (95 % CI 0·16, 0·25). Participants with high adherence had higher cost associated with the healthier components (e.g. vegetables, fruits and fish), and lower cost associated with the unhealthy components (e.g. red meat, processed meat and sweets) (P for trend<0·001 each). In total, 20·7 % (95 % CI 14·3, 27·0) of the MDS-cost association was explained by the selected socio-economic factors, and the MDS-cost association was of greater magnitude in lower socio-economic groups (P interaction<0·005). Overall, greater adherence to the Mediterranean diet was associated with marginally higher dietary cost, partly modified and explained by socio-economic status, but the potential economic barriers of high adherence might be offset by cost saving from reducing unhealthy food consumption.

Abstract
OBJECTIVE In Ireland, the major causes of death are CVD. The current Irish healthy eating guidelines and food pyramid primarily advocate a low-fat diet. However, there is overwhelming scientific evidence for the benefits of a Mediterranean diet (Med Diet) in the prevention and management of metabolic disease as well as improving overall health and well-being. In the current commentary, the rationale to incorporate the principles of the Med Diet into the Irish dietary guidelines is presented. DESIGN Perspectives of authors. SETTING Local and international. SUBJECTS Populations in Europe, North America and Australia. RESULTS Adopting components of the Med Diet presents a more evidence-based approach to updating the current Irish dietary guidelines. Experience and lessons from other non-Mediterranean countries show that it could be a feasible and effective solution to improving the dietary habits of the Irish population to prevent and mange chronic diseases. CONCLUSIONS Policies and programmes to address perceived barriers to the Med Diet's implementation and uptake in non-Mediterranean countries should be promoted.

Abstract
An ageing population and growing prevalence of chronic diseases including cardiovascular disease (CVD) and type 2 diabetes (T2D) are putting increased pressure on healthcare expenditure in Australia. A cost of illness analysis was conducted to assess the potential savings in healthcare expenditure and productivity costs associated with lower prevalence of CVD and T2D resulting from increased intake of cereal fibre. Modelling was undertaken for three levels of increased dietary fibre intake using cereal fibre: a 10% increase in total dietary fibre; an increase to the Adequate Intake; and an increase to the Suggested Dietary Target. Total healthcare expenditure and productivity cost savings associated with reduced CVD and T2D were calculated by gender, socioeconomic status, baseline dietary fibre intake, and population uptake. Total combined annual healthcare expenditure and productivity cost savings of AUD$17.8 million-$1.6 billion for CVD and AUD$18.2 million-$1.7 billion for T2D were calculated. Total savings were generally larger among adults of lower socioeconomic status and those with lower dietary fibre intakes. Given the substantial healthcare expenditure and productivity cost savings that could be realised through increases in cereal fibre, there is cause for the development of interventions and policies that encourage an increase in cereal fibre intake in Australia.

Abstract
Consumption of dietary pulses, including beans, peas and lentils, is recommended by health authorities across jurisdictions for their nutritional value and effectiveness in helping to prevent and manage major diet-related illnesses of significant socioeconomic burden. The aim of this study was to estimate the potential annual healthcare and societal cost savings relevant to rates of reduction in complications from type 2 diabetes (T2D) and incidence of cardiovascular disease (CVD) following a low glycemic index (GI) or high fiber diet that includes pulses, or 100 g/day pulse intake in Canada, respectively. A four-step cost-of-illness analysis was conducted to: (1) estimate the proportions of individuals who are likely to consume pulses; (2) evaluate the reductions in established risk factors for T2D and CVD; (3) assess the percent reduction in incidences or complications of the diseases of interest; and (4) calculate the potential annual savings in relevant healthcare and related costs. A low GI or high fiber diet that includes pulses and 100 g/day pulse intake were shown to potentially yield Can$6.2 (95% CI $2.6-$9.9) to Can$62.4 (95% CI $26-$98.8) and Can$31.6 (95% CI $11.1-$52) to Can$315.5 (95% CI $110.6-$520.4) million in savings on annual healthcare and related costs of T2D and CVD, respectively. Specific provincial/territorial analyses suggested annual T2D and CVD related cost savings that ranged from up to Can$0.2 million in some provinces to up to Can$135 million in others. In conclusion, with regular consumption of pulse crops, there is a potential opportunity to facilitate T2D and CVD related socioeconomic cost savings that could be applied to Canadian healthcare or re-assigned to other priority domains. Whether these potential cost savings will be offset by other healthcare costs associated with longevity and diseases of the elderly is to be investigated over the long term.

Health benefits and evaluation of healthcare cost savings if oils rich in monounsaturated fatty acids were substituted for conventional dietary oils in the United States. Nutr Rev 2017; 75:163-174.

Abstract
The impact of nutritional behaviors on health is beyond debate and has the potential to affect the economic outputs of societies in significant ways. Dietary fatty acids have become a central theme in nutrition research in recent years, and the popularity of dietary oils rich in healthy fatty acids, such as monounsaturated fatty acid (MUFA), for cooking applications and use in food products has increased. Here, the objective is to summarize the health effects of MUFA-rich diets and to systematically estimate the potential healthcare and societal cost savings that could be realized by increasing MUFA intakes compared with other dietary fat intakes in the United States. Using a scoping review approach, the literature of randomized controlled clinical trials was searched and a 4-step cost-of-illness analysis was developed, which included estimates of success rate, disease biomarker reduction, disease incidence reduction, and cost savings. Findings revealed improvements in established biomarkers and in incidence of coronary heart disease and type 2 diabetes, along with potentially substantial annual healthcare and societal cost savings when recommendations for daily MUFA intake were followed. In summary, beyond the beneficial health effects of MUFA-rich diets, potential economic benefits suggest practical implications for consumers, food processors, and healthcare authorities alike.

Abstract
OBJECTIVE To characterize the multiple dimensions and benefits of the Mediterranean diet as a sustainable diet, in order to revitalize this intangible food heritage at the country level; and to develop a multidimensional framework - the Med Diet 4.0 - in which four sustainability benefits of the Mediterranean diet are presented in parallel: major health and nutrition benefits, low environmental impacts and richness in biodiversity, high sociocultural food values, and positive local economic returns. DESIGN A narrative review was applied at the country level to highlight the multiple sustainable benefits of the Mediterranean diet into a single multidimensional framework: the Med Diet 4.0. Setting/subjects We included studies published in English in peer-reviewed journals that contained data on the characterization of sustainable diets and of the Mediterranean diet. The methodological framework approach was finalized through a series of meetings, workshops and conferences where the framework was presented, discussed and ultimately refined. RESULTS The Med Diet 4.0 provides a conceptual multidimensional framework to characterize the Mediterranean diet as a sustainable diet model, by applying principles of sustainability to the Mediterranean diet. CONCLUSIONS By providing a broader understanding of the many sustainable benefits of the Mediterranean diet, the Med Diet 4.0 can contribute to the revitalization of the Mediterranean diet by improving its current perception not only as a healthy diet but also a sustainable lifestyle model, with country-specific and culturally appropriate variations. It also takes into account the identity and diversity of food cultures and systems, expressed within the notion of the Mediterranean diet, across the Mediterranean region and in other parts of the world. Further multidisciplinary studies are needed for the assessment of the sustainability of the Mediterranean diet to include these new dimensions.

Abstract
AIMS The traditional Mediterranean diet (MD) is reportedly associated with lower risk of major chronic diseases and long considered to contribute to the reduced rates of cardiovascular and cerebrovascular events and to the highest life expectancy in adults who lived near the Mediterranean Sea. But despite its widely documented health benefits, adherence to this dietary pattern has been rapidly declining over the last decades due to a clear socioeconomic influence. The present review provides an overview of the evidence on the current major determinants of adherence to the Mediterranean diet, with a particular emphasis on Mediterranean Countries at a time of economic crisis; second it explores emerging socioeconomic inequalities in other domains of healthy dietary behaviours such as dietary variety, access to organic foods and food purchasing behaviour. DATA SYNTHESIS According to ecological evidence, the Mediterranean Countries that used to have the highest adherence to the Mediterranean pattern in the Sixties, more recently experienced the greatest decrease, while Countries in Northern Europe and some other Countries around the world are currently embracing a Mediterranean-like dietary pattern. A potential cause of this downward trend could be the increasing prices of some food items of the Mediterranean diet pyramid. Recent evidence has shown a possible involvement of the economic crisis, material resources becoming strong determinants of the adherence to the MD just after the recession started in 2007-2008. Beyond intake, the MD also encourages increasing dietary diversity, while international dietary recommendations suggest replacing regular foods with healthier ones. CONCLUSIONS Socioeconomic factors appear to be major determinants of the adherence to MD and disparities also hold for other indices of diet quality closely related to this dietary pattern.

Abstract
BACKGROUND The Mediterranean diet has positively influenced various medical conditions, but only a paucity of studies has considered the relation between the Mediterranean diet and quality of life (QOL) among people living in North America. OBJECTIVE We investigated whether a higher adherence to the Mediterranean diet (aMED) was associated with better QOL and decreased pain, stiffness, disability, and depression in a large cohort of North Americans from the Osteoarthritis Initiative. DESIGN aMED was evaluated through a validated Mediterranean diet score categorized into quintiles. Outcomes of interest were QOL [assessed with the 12-Item Short-Form Health Outcome Survey (SF-12)]; disability, pain, and stiffness [assessed in both knees with the Western Ontario and McMaster Universities Arthritis Index (WOMAC)]; and depressive symptoms [assessed with the Center for Epidemiologic Studies Depression Scale (CES-D)]. RESULTS Of the 4470 participants (2605 women; mean age: 61.3 y), those with a higher aMED had significantly more favorable scores on all outcomes investigated (P < 0.0001 for all comparisons). After adjustment for potential confounders in linear regression analyses, a higher aMED was significantly associated with a higher SF-12 physical composite scale value (β: 0.10; 95% CI: 0.05, 0.15; P < 0.0001), lower WOMAC scores (except for stiffness), and lower CES-D scores (β: -0.05; 95% CI: -0.09, -0.01; P = 0.01). An adjusted logistic regression analysis, taking as reference those in the 2 highest quintiles of the aMED score, confirmed these findings. CONCLUSION Higher aMED is associated with better QOL and decreased pain, disability, and depressive symptoms. This trial was registered at clinicaltrials.gov as NCT00080171.

Food Nutr Res 2015; 59:28646. [PMID: 26652739 PMCID: PMC4677277 DOI: 10.3402/fnr.v59.28646] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2015] [Revised: 11/03/2015] [Accepted: 11/04/2015] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Evidence-based research highlights beneficial impacts of dietary fibre on several aspects of the gut pathophysiology that are accompanied by a considerable financial burden in healthcare services. Recommended intakes of dietary fibre may thus associate with financial benefits at a population level. OBJECTIVE We sought to systematically assess the potential annual savings in healthcare costs that would follow the reduction in rates of functional constipation and irregularity with increased dietary fibre intakes among Canadian adults. DESIGN A cost-of-illness analysis was developed on the basis of current and recommended levels of fibre intake in Canada, constipation reduction per 1 g fibre intake, proportion of adults who are likely to consume fibre-rich diets, and population expected to respond to fibre intake. Sensitivity analyses covering a range of assumptions were further implemented within the economic simulation. RESULTS Our literature searches assumed a 1.8% reduction in constipation rates with each 1 g/day increase in fibre intake. With intakes corresponding to the Institute of Medicine's adequate levels of 38 g/day for men and 25 g/day for women, among 5 and 100% of the adult populations, anywhere between CAD$1.5 and CAD$31.9 million could be saved on constipation-related healthcare costs annually. Each 1 g/day increase in dietary fibre was estimated to result in total annual healthcare cost savings that ranged between CAD$0.1 and CAD$2.5 million. CONCLUSIONS The present research suggests an economic value of increasing dietary fibre intake beyond its well-known health benefits. Healthy-eating behaviours consistent with the recommended intakes of dietary fibre by the general public should hence be advocated as a practical approach for reducing costs associated with the management of constipation in Canada.
