The palm or the plate? An assessment of dietary guideline promotion, awareness, and preferences among Saudis: cross-sectional survey

BACKGROUND

Dietary Guidelines for Saudis are offered and promoted in two forms: the Healthy Food Palm and the Saudi Healthy Plate. However, public awareness, recognition, and engagement with these guidelines is not well studied. Understanding the factors behind dietary guideline promotion, awareness, recognition, and use may lead to greater optimization of and engagement with the guidelines. This study aims to assess recognition of and public engagement with the My Palm and My Plate dietary guidelines as well as dietary guideline awareness, perceptions, and preferences among Saudis.

METHODS

To compare awareness, knowledge, and usability between the Healthy Food Palm and the Saudi Healthy Plate dietary guidelines, a cross-sectional survey-based study was conducted among Saudi adult males and females above 18 (n = 674) between October 2021 and January 2022. Participants were split into groups based on age and gender. T-test and χ2 tests were used to determine differences between groups for continuous and categorical variables, respectively.

RESULTS

Most participants were unaware of the Healthy Food Palm and the Saudi Healthy Plate guidelines, with only 11.1% and 30.3% able to recognize guideline-associated visual illustrations, respectively. However, nearly half of the participants correctly identified the number of food groups in the Healthy Food Palm and Saudi Healthy Plate. As well, more than half of the sample preferred the Saudi Healthy Plate, while one-quarter of the sample preferred neither guideline. In terms of future public health promotion, participants identified that "convenience and availability" (29.6%) and "my own health" (28.6%) were the most influential dietary choice factors with "social media campaigns" (2.4%) and the involvement of "an influencer" (3.1%) being the least influential dietary choice factors.

CONCLUSIONS

Implementation of and public awareness of dietary guidelines is less than optimal, and opportunities exist for greater information dissemination and public engagement. Measurement and ongoing evaluation of public dietary guideline awareness and use and a more in-depth understanding of dietary choice influences and behaviors are important considerations for dietary guideline development and promotion.

Legumes—A Comprehensive Exploration of Global Food-Based Dietary Guidelines and Consumption

Despite the well-known human and planetary health benefits of legumes, consumption is often low. This scoping review aimed to evaluate the inclusion of legumes in global food-based dietary guidelines (FBDG), and to review consumption data against global food group classifications for legumes. The review of FBDG from 94 countries identified legume-based key messaging, the key terms used to define legumes, recommended serving size and frequency of consumption and the classification of legumes into food groups as depicted by food guides. The 2018 Global Dietary Database isolated consumption data of legumes and beans using individual-level, nationally representative dietary survey data for matched countries. Food-based dietary guidelines from 40/94 countries most often identified legumes utilising the term legumes, followed by beans (n = 13), pulses (n = 10), or as beans, peas and lentils (n = 5). The serving size recommendations for legume consumption varied widely, and there was no consistency in the suggested frequency of consumption. Median bean and legume consumption for countries with FBDG ranged from 1.2 g/d (Norway) to 122.7 g/d (Afghanistan). Classification of legumes into food groups varied, with 38% of countries categorising legumes in the protein-rich food group, 20% were in a group on their own and 15% were in the starchy staples group. In countries where legumes were together with either nuts or seeds had the greatest range in intake (11.6–122.7 g/day), followed by those that grouped legumes together with protein-rich foods (4.0–104.7 g/day), while countries that grouped legumes into two food groups, in an attempt to promote consumption, tended to have a lower consumption. Greater emphasis and perhaps repositioning of legumes in dietary guidelines may be required to encourage consumption for health, environmental and economic benefits.

Consumer Understanding of the Australian Dietary Guidelines: Recommendations for Legumes and Whole Grains

Dietary guidelines provide evidence-based guidance for healthy individuals to improve dietary patterns, although they are most often based on individual foods or food groups. Legumes are a class of food included in current Australian Dietary Guidelines (ADG), mentioned in two of the five food groups, as a vegetable and as an alternative to meat. Whole grain consumption is encouraged in ADG via the statement focused on cereal grains due to their health-promoting properties. Despite their prominence in guidelines, average legume and whole grain consumption in Australia remains lower than recommendations outlined in the ADG. This exploratory study aimed to understand consumer perspectives of wording utilised in dietary guidelines specifically focused on legumes and whole grains. Based on the analysis, there was a significant preference for the statement “each day, consume at least one serve of legumes either as a serve of vegetables or as an alternative to meat” (p < 0.05), which provides a specific frequency and quantification for legume consumption. For whole grain, the significantly preferred statement was “choose whole grain products over refined grains/white flour products whenever you can” indicating a less prescriptive option. Effective messaging in guidelines could consider greater specificity regarding frequency, quantity and quality of foods recommended. This exploratory study suggests an improvement in the adoption and consumption of legumes and whole grains in the Australian diet may be better facilitated through consumer-tested messaging.

The gut microbiome as mediator between diet and its impact on immune function

Dietary habits may affect inflammatory status in humans. Here we explore this interaction as well as the potential mediating role of the gut microbiome (GM), given that the GM is both involved in processing of dietary components and influences the immune system. A cross-sectional analysis of a sample of 482 healthy participants (207 males and 275 females) was performed. Dietary intake was assessed by a semiquantitative food questionnaire. Adipokines and soluble inflammatory mediators were assayed with multiple immunoassays and ELISA. Microbial DNA was extracted from frozen stool samples of 471 participants. Polychoric correlation analysis was used to establish dietary patterns, and joint multivariate associations between these dietary patterns and immune biomarkers were studied using regression analyses with adjustment for sex, age, BMI, smoking, education levels and physical exercise and other dietary patterns. Non-parametric entropy mediation was applied to investigate whether diet-immune relationships are mediated by abundance of microbial species. In this cohort, we identified three dietary patterns, characterized as “high-meat” (meat and sweetened drink), “prudent diet” (fish, fruit, legumes and vegetables) and “high alcohol” (higher alcohol consumption). Higher adherence to prudent diet was associated with a higher adiponectin level. The high alcohol pattern was associated with high concentrations of circulating concentrations of pro-inflammatory markers (CRP, IL-6, VEGF). Dialister invisus was found to mediate the relationship between a prudent dietary pattern and adiponectin, AAT, CRP, IL-6, and VEGF. In conclusion, a meat-based diet and a diet with high alcohol consumption were associated with high concentrations of biomarkers of chronic low-grade inflammation, and conversely, a prudent diet was associated with anti-inflammatory biomarkers. Diet-inflammation regulation may differ between sexes. Mediation analyses revealed that the association between prudent diet and immune function was partially mediated by the GM. The study adds to our understanding of the associations between diet, the immune system and the GM in a healthy population.

The carbon footprint of dietary guidelines around the world: a seven country modeling study

Background

Do the environmental impacts inherent in national food-based dietary guidelines (FBDG) vary around the world, and, if so, how? Most previous studies that consider this question focus on a single country or compare countries’ guidelines without controlling for differences in country-level consumption patterns. To address this gap, we model the carbon footprint of the dietary guidelines from seven different countries, examine the key contributors to this, and control for consumption differences between countries.

Methods

In this purposive sample, we obtained FBDG from national sources for Germany, India, the Netherlands, Oman, Thailand, Uruguay, and the United States. These were used to structure recommended diets using 6 food groups: protein foods, dairy, grains, fruits, vegetables, and oils/fats. To determine specific quantities of individual foods within these groups, we used data on food supplies available for human consumption for each country from the UN Food and Agriculture Organization’s food balance sheets. The greenhouse gas emissions (GHGE) used to produce the foods in these consumption patterns were linked from our own database, constructed from an exhaustive review of the life cycle assessment literature. All guidelines were scaled to a 2000-kcal diet.

Results

Daily recommended amounts of dairy foods ranged from a low of 118 ml/d for Oman to a high of 710 ml/d for the US. The GHGE associated with these two recommendations were 0.17 and 1.10 kg CO₂-eq/d, respectively. The GHGE associated with the protein food recommendations ranged from 0.03 kg CO₂-eq/d in India  to 1.84 kg CO₂-eq/d in the US, for recommended amounts of 75 g/d and 156 g/d, respectively. Overall, US recommendations had the highest carbon footprint at 3.83 kg CO₂-eq/d, 4.5 times that of the recommended diet for India, which had the smallest footprint. After controlling for country-level consumption patterns by applying the US consumption pattern to all countries, US recommendations were still the highest, 19% and 47% higher than those of the Netherlands and Germany, respectively.

Conclusions

Despite our common human biology, FBDG vary tremendously from one country to the next, as do the associated carbon footprints of these guidelines. Understanding the carbon footprints of different recommendations can assist in future decision-making to incorporate environmental sustainability in dietary guidance.

The association between body weight dissatisfaction with unhealthy eating behaviors and lack of physical activity in adolescents: A systematic review

A systematic review examined the association between body weight dissatisfaction with unhealthy eating behaviors and lack of physical activity in adolescents, since it represents an alert to adolescent's health and well-being. Six electronic databases and gray literature were systematically searched from January 1980 to December 2018. A total of 11 articles met the inclusion criteria. Included studies assessed body weight dissatisfaction using different dimensions/components: satisfaction component of the attitudinal dimension was assessed in five studies, behavior component of the attitudinal dimension was assessed in two studies, perceptual dimension was assessed in two studies, and two studies were unclear about dimension. Behaviors: two assessed only unhealthy eating behaviors, six assessed lack of physical activity, and three assessed both behaviors. Only three studies found an association between body weight dissatisfaction with unhealthy eating behaviors, three with lack of physical activity, and one did not perform a statistical test for an association between body weight dissatisfaction with unhealthy eating behaviors and lack of physical activity. Few studies have reported an association between body weight dissatisfaction with one of these unhealthy behaviors. There was substantial heterogeneity related to unit of measures, both for body weight dissatisfaction and for behaviors studied.

Fruit and vegetable consumption among South Asians: A systematic review and meta-analysis

BACKGROUND AND AIMS

Low consumption of fruit and vegetables is associated with high prevalence of non-communicable diseases, especially among South Asians. The aim of our study was to systematically review data published on fruit and vegetable intake among South Asian countries.

METHODS

This review included 43 studies conducted from December 1999 to 2019 among South Asians. Literature searching was undertaken in PubMed® database and World Health Organization website. The main outcomes were pooled using random effect meta-analysis.

RESULTS

The highest fruit consumption by both men and women (2.4 servings/day) was found in Bhutan (2004) while the lowest reports (0.43 servings/day) were from Sri Lanka (2011) and Bangladesh (2002). With regard to vegetable consumption, Indians (2007) had the lowest reported intake (0.9 servings/day), while the highest value, 3.8 servings/day, was reported in Bhutanese adults (2014). When both intakes were considered, the highest (4.28; 95% CI, 4.02 to 4.55; p=0.15; I²=51%, p<0.001) and the lowest (1.83; 95% CI, 1.41 to 2.25; p<0.001; I²=100%, p<0.001) pooled mean values, were attained for Bhutan and Bangladesh, respectively. The highest percentage of respondents (86.2%) achieved the World Health Organization recommendation of five fruit and vegetables (400 g) per day in Afghanistan (2013) whereas the lowest (0%) reported in Bangladesh (2005).

CONCLUSIONS

Residents of almost all South Asian countries appear to consume extremely low quantities of fruit and vegetables, lower than the World Health Organization recommendation. Hence, immediate initiatives should be implemented to enhance the intake of fruit and vegetables across the region.

The Extent of Maternal Nutritional Knowledge and Practice During Lactation in Kombolcha Town, South Wollo Zone, Ethiopia: A Mixed Study Design

Objective

The study aimed to assess nutritional practice and its associated factors among lactating mothers in Kombolcha Town, South Wollo Zone, Amhara Region, Ethiopia, 2017.

Design and Setting

A community-based cross-sectional study design supplemented with qualitative research was conducted at Kombolcha Town from October 23 to November 10, 2017. A systematic sampling technique was used to select the study participants from listed households and purposive sampling was used for the qualitative inquiry.

Participants

A total of 425 lactating mothers were interviewed using a pre-tested structured questionnaire. The data were analyzed using Statistical Package for Social Sciences version 23. For the qualitative data, thematic content analysis was used. Multiple logistic regression was used to evaluate the association between nutritional practice with independent variables.

The Results

Lactating mothers who had good nutritional practice and knowledge were 28.7% (95% CI: 24.9%, 33.5%) and 52.0% (95% CI: 47.1%, 57.6%) respectively. This study revealed that government-employed mothers (AOR=6.0, 95% CI: 1.953, 18.485) and mothers with good nutritional knowledge (AOR=3.12, 95% CI: 1.832, 5.318) had statistically significant associations with nutritional practices of lactating mothers.

Conclusions and Recommendations

The nutritional practices and knowledge of lactating mothers were low in the study area. The mother’s occupation and nutritional knowledge were significantly associated with nutritional practice. Hence, the provision of maternal nutritional education regarding a healthy diet, and timely and regular dissemination of nutritional information were recommended.

Increasing physical activity and healthy diet in outpatients with mental disorders: a randomized-controlled evaluation of two psychological interventions

INTRODUCTION

While physical activity (PA) can play an important role in the treatment of mental disorders (MD), large proportions of patients with MD do not meet PA recommendations. The aim of this trial was to evaluate whether structured psychological intervention (MoVo-LISA) is effective in helping outpatients with MD to increase their level of PA. As active control group (CG) we modified MoVo-LISA to target healthy diet behavior.

METHODS

N = 83 outpatients with MD (F1-F4) were randomized to the two conditions. PA (self-report and accelerometry), dietary behavior, social-cognitive determinants of health behavior change, psychiatric symptoms and health-related quality of life were assessed at baseline, 1 and 12 weeks after the intervention.

RESULTS

Significant time*group interaction effects for objectively measured PA, dietary behavior and fruit and vegetable consumption indicated differential effects of the interventions on these outcomes. PA increased in the MoVo-LISA group (IG) from baseline to follow-up while it decreased in CG. IG showed a significant higher level of objectively measured PA at follow-up compared to CG. Dietary behavior and fruit and vegetable consumption significantly increased from baseline to follow-up in CG, but not IG. IG showed a significant increase in some, but not all social cognitive determinants of health behavior change.

CONCLUSIONS

MoVo-LISA is effective in helping outpatients with MD to increase their level of PA in short- and mid-term. The used intervention strategies are effective for the promotion of healthy diet in patients with MD as well.

Food-based dietary guidelines of Arabic-speaking countries: a culturally congruent profile

OBJECTIVE

Dietary guidelines for food groups, types and portion sizes are common practice at the national level. As the relationship between nutrition and disease and the influence of cultural identity on individual behaviour become clearer, dietary guidelines necessarily evolve. Today, the Arabic-speaking region is experiencing a dual burden of undernutrition and increasing rates of overweight and obesity. Cultural congruency among dietary guidelines in the Arabic-speaking region and how they affect health education, health promotion, and nutrition programme planning or individual dietary behaviours have yet to be examined. The present work provides dietitians and public health professionals a narrative review of proposed food guidelines for the Arabic-speaking region.

DESIGN

The current review examined five established dietary guidelines within the Arabic-speaking region, namely the Arab Food Dome (Arab Gulf states), the Healthy Food Palm (Saudi Arabia), the Lebanese Dietary Guidelines, the Omani Guide to Healthy Eating and the Qatar Dietary Guidelines, and compared findings with the regional Eastern Mediterranean guidelines developed by the WHO. Individual guideline recommendations are tabled for comparative review.

SETTING

The Arabic-speaking region.ParticipantsRespective Arabic-speaking populations.

RESULTS

Health educators, community health practitioners and nutrition professionals can benefit from the cultural contexts associated with dietary guidelines in this region.

CONCLUSIONS

Community-level policy and individual behaviour change will benefit from cultural sensitivity; health communication and behaviour change programming require cultural competence provided in the present review; and programme evaluation efforts (prior to and after implementation) should include a detailed understanding of how culture shapes regional policy and individual nutrition behaviours.

Comparison of government recommendations for healthy eating habits in visual representations of food-based dietary guidelines in Latin America

Visual representations of food-based dietary guidelines (FBDG) express diverse dietary and sociocultural norms, especially as they relate to healthy eating habits. This article investigates government recommendations for healthy eating habits expressed in the visual representation of Latin American FBDGs. Drawing on 15 images published between 1991 and 2017, we conducted an anthropological visual analysis guided by the methodology proposed by James Collier and Malcolm Collier: unstructured analyses, open viewing analyses, structured analyses and microanalyses. Here, we explore government recommendations based on visual representation shapes, food classification systems, lifestyle recommendations and embedded sociocultural elements. Our main findings relate to how dietary and sociocultural norms are used to promote eating practices considered healthy. Dietary norms focus on variety, proportionality, and moderation, as expressed in terms of food classification and food standards considered healthy. Sociocultural norms are referenced by the use of cultural symbols as strategies to promote traditional foods, cooking practices, commensality, water consumption and physical activity. Ultimately, we argue that FBDG visual representations contain embedded messages that counsel individuals to plan, buy, prepare and consume food with family; to consume foods considered healthy; to pay full attention to their meals, without distractions, such as television and cell phones; and to celebrate traditional, local and/or native foods and culinary preparations.

Development of Criteria for Incorporating Occasionally Consumed Foods into a National Dietary Guideline: A Practical Approach Adapted to the Spanish Population

Food-based dietary guidelines (FBDGs) offer recommendations that help population to meet nutrient requirements. Most European FBDGs include quantitative information regarding daily and weekly consumed foods, but for occasionally consumed foods, they only recommend limiting their intake, without giving specific advice on portions. As these foods are consumed by the general population as a part of the cultural and culinary tradition of each country, it is important to establish the maximum frequency and the portions that would be acceptable to be included in a healthy eating pattern. This study outlines the methodology to include these foods in a national (Spanish) FBDG. Firstly, commonly consumed foods were selected and grouped, and portions were defined according to their nutritional value, so different foods within a group could be exchanged. Then, macronutrient profiles of occasionally consumed foods were compared to the frequently consumed food groups to determine to what extent they had a similar nutritional content. Finally, some combinations of foods, with or without the inclusion of occasionally consumed groups, were calculated. A maximum number of servings per group was defined according to their energy and nutrient content. Occasionally consumed foods can be included in a healthy diet as long as they are consumed in the small quantities as shown in this study and as long as they replace equivalent portions of other foods of frequent consumption. This new tool shows how to include occasionally consumed foods in a diet while maintaining its overall nutritional quality.

Few European Adults are Living a Healthy Lifestyle

PURPOSE

This study aimed to measure healthy lifestyle for European adults.

DESIGN

Cross-sectional study.

SETTINGS

In 20 European countries.

PARTICIPANTS

A total of 34 993 (16 749 men, 18 244 women) European adults.

MEASURES

Data were from the 2014 European Social Survey (n = 34 993) on 4 modifiable behaviors (physical activity, fruit and vegetable consumption, not drinking alcohol to excess, and not smoking) as well as sleep quality.

ANALYSIS

Behaviors were combined and formed a healthy lifestyle measure. Binary logistic regression was done to determine associations of healthy lifestyle and sociodemographic characteristics.

RESULTS

Only 5.8% of the adults reported a healthy lifestyle. The prevalence of having a healthy lifestyle varied among European countries. The lowest rates were in Hungary (1.3%) and Czech Republic (1.9%). The highest rates were in United Kingdom (8.6%) and Finland (9.2%). Those who presented a higher likelihood of having a healthy lifestyle were middle age (odds ratio [OR] = 1.20), older people (OR = 1.34), having higher household income (OR = 1.33), being a student (OR = 1.38), and retired (OR = 1.31). Those less likely to have a healthy lifestyle were lived without a partner (OR = 0.82), unemployed (OR = 0.73), and lived in rural areas (OR = 0.86).

CONCLUSIONS

Few European adults were practicing 5 healthy behaviors. This should be a message for governments and be considered in the establishment of preventive public policies in the areas of health and health education.

Dietary practices and associated factors during pregnancy in northwestern Ethiopia

Background

Pregnancy is the most crucial nutritionally demanding period of every woman’s life. The high demand of nutrients to deposit energy in the form of new tissue, growth of existing maternal tissues such as breast and uterus and increased energy requirements for tissue synthesis makes pregnant women more vulnerable to malnutrition. Dietary practice is defined as an observable actions or behavior of dietary habit and can be classified as good dietary practices and poor dietary practices. The incidence of dietary inadequacies as a result of dietary habits and patterns in pregnancy is higher during pregnancy when compared to any other stage of the life cycle. Thus, this study aimed to assess dietary practices and associated factors during pregnancy in Bahir Dar town, Northwest Ethiopia.

Methods

A community based cross sectional study was conducted from March 1 to April 1, 2016. A total of 616 pregnant women were participated in the study. All eligible pregnant women were identified through house-to-house visit with the help of health extension workers. Cluster sampling was used to select eligible pregnant women. The data were collected using interviewer administered questionnaire prepared in English and translated in to Amharic. Data were analyzed by using Statistical Package for Social Sciences (SPSS) version 20. Multivariate logistic regression analysis was employed to identify factors associated with dietary practices.

Result

This study has shown that 39.3% of the study participants had good dietary practices and the rest 60.7% of pregnant women reported poor dietary practices. Concerning dietary knowledge, 61.4% of the study participants had good dietary knowledge while 38.6% had poor dietary knowledge. Husband income, ownership of radio, history of disease and dietary knowledge were shown to have significant association (P < 0.05) with dietary practices.

Conclusion

Dietary practices of pregnant women in the study area was suboptimal. Husband income, ownership of radio, history of disease and dietary knowledge were independent predictors of women dietary practices. Awareness should be created among pregnant women by concerned bodies such as governmental and non-governmental organization through local mass media.

Fruit, vegetable, and legume intake, and cardiovascular disease and deaths in 18 countries (PURE): a prospective cohort study

BACKGROUND

The association between intake of fruits, vegetables, and legumes with cardiovascular disease and deaths has been investigated extensively in Europe, the USA, Japan, and China, but little or no data are available from the Middle East, South America, Africa, or south Asia.

METHODS

We did a prospective cohort study (Prospective Urban Rural Epidemiology [PURE] in 135 335 individuals aged 35 to 70 years without cardiovascular disease from 613 communities in 18 low-income, middle-income, and high-income countries in seven geographical regions: North America and Europe, South America, the Middle East, south Asia, China, southeast Asia, and Africa. We documented their diet using country-specific food frequency questionnaires at baseline. Standardised questionnaires were used to collect information about demographic factors, socioeconomic status (education, income, and employment), lifestyle (smoking, physical activity, and alcohol intake), health history and medication use, and family history of cardiovascular disease. The follow-up period varied based on the date when recruitment began at each site or country. The main clinical outcomes were major cardiovascular disease (defined as death from cardiovascular causes and non-fatal myocardial infarction, stroke, and heart failure), fatal and non-fatal myocardial infarction, fatal and non-fatal strokes, cardiovascular mortality, non-cardiovascular mortality, and total mortality. Cox frailty models with random effects were used to assess associations between fruit, vegetable, and legume consumption with risk of cardiovascular disease events and mortality.

FINDINGS

Participants were enrolled into the study between Jan 1, 2003, and March 31, 2013. For the current analysis, we included all unrefuted outcome events in the PURE study database through March 31, 2017. Overall, combined mean fruit, vegetable and legume intake was 3·91 (SD 2·77) servings per day. During a median 7·4 years (5·5-9·3) of follow-up, 4784 major cardiovascular disease events, 1649 cardiovascular deaths, and 5796 total deaths were documented. Higher total fruit, vegetable, and legume intake was inversely associated with major cardiovascular disease, myocardial infarction, cardiovascular mortality, non-cardiovascular mortality, and total mortality in the models adjusted for age, sex, and centre (random effect). The estimates were substantially attenuated in the multivariable adjusted models for major cardiovascular disease (hazard ratio [HR] 0·90, 95% CI 0·74-1·10, p_trend=0·1301), myocardial infarction (0·99, 0·74-1·31; p_trend=0·2033), stroke (0·92, 0·67-1·25; p_trend=0·7092), cardiovascular mortality (0·73, 0·53-1·02; p_trend=0·0568), non-cardiovascular mortality (0·84, 0·68-1·04; p_trend =0·0038), and total mortality (0·81, 0·68-0·96; p_trend<0·0001). The HR for total mortality was lowest for three to four servings per day (0·78, 95% CI 0·69-0·88) compared with the reference group, with no further apparent decrease in HR with higher consumption. When examined separately, fruit intake was associated with lower risk of cardiovascular, non-cardiovascular, and total mortality, while legume intake was inversely associated with non-cardiovascular death and total mortality (in fully adjusted models). For vegetables, raw vegetable intake was strongly associated with a lower risk of total mortality, whereas cooked vegetable intake showed a modest benefit against mortality.

INTERPRETATION

Higher fruit, vegetable, and legume consumption was associated with a lower risk of non-cardiovascular, and total mortality. Benefits appear to be maximum for both non-cardiovascular mortality and total mortality at three to four servings per day (equivalent to 375-500 g/day).

Nutritional Guidelines and Fermented Food Frameworks

This review examines different nutritional guidelines, some case studies, and provides insights and discrepancies, in the regulatory framework of Food Safety Management of some of the world’s economies. There are thousands of fermented foods and beverages, although the intention was not to review them but check their traditional and cultural value, and if they are still lacking to be classed as a category on different national food guides. For understanding the inconsistencies in claims of concerning fermented foods among various regulatory systems, each legal system should be considered unique. Fermented foods and beverages have long been a part of the human diet, and with further supplementation of probiotic microbes, in some cases, they offer nutritional and health attributes worthy of recommendation of regular consumption. Despite the impact of fermented foods and beverages on gastro-intestinal wellbeing and diseases, their many health benefits or recommended consumption has not been widely translated to global inclusion in world food guidelines. In general, the approach of the legal systems is broadly consistent and their structures may be presented under different formats. African traditional fermented products are briefly mentioned enhancing some recorded adverse effects. Knowing the general benefits of traditional and supplemented fermented foods, they should be a daily item on most national food guides.

Potential Health Benefits of Combining Yogurt and Fruits Based on Their Probiotic and Prebiotic Properties

Fruit and yogurt have been identified individually as indicators of healthy dietary patterns. Fruits are relatively low in energy density and are an excellent source of antioxidants and prebiotic fibers and polyphenols, which can promote digestive health. Yogurt, on the other hand, is a nutrient-dense food that is a good source of dairy protein, calcium, magnesium, vitamin B-12, conjugated linoleic acid, and other key fatty acids. In addition, it contains beneficial bacterial cultures, making it a potential source of probiotics. Yogurt's unique fermented food matrix provides added health benefits by enhancing nutrient absorption and digestion. Combining the intake of yogurt and fruit could provide probiotics, prebiotics, high-quality protein, important fatty acids, and a mixture of vitamins and minerals that have the potential to exert synergistic effects on health. Yogurt consumption has been associated with reduced weight gain and a lower incidence of type 2 diabetes, whereas fruits have established effects on reducing the risk of cardiovascular disease. Yogurt and fruits can be eaten together and may exert combined health benefits through potential prebiotic and probiotic effects. Furthermore, substituting high-energy, nutrient-deficient snacks with fruit and yogurt could reduce the intake of high-calorie obesogenic foods. In light of the positive cardiometabolic impacts of fruit and yogurt and their association with healthy dietary patterns, there is sufficient evidence to warrant further exploration into the potential synergistic health benefits of a combined intake of fruit and yogurt.

Preço dos alimentos no Brasil: prefira preparações culinárias a alimentos ultraprocessados

Resumo: Estudo com objetivo de descrever o preço dos grupos de alimentos consumidos no Brasil considerando a natureza, a extensão e o propósito de seu processamento. Dados provenientes da Pesquisa de Orçamentos Familiares de 2008-2009 foram utilizados. O preço médio dos grupos (in natura, ingredientes culinários, processados e ultraprocessados) e seus respectivos subgrupos de alimentos foram estimados para o Brasil segundo renda, região e área. Os produtos in natura e ingredientes culinários apresentaram menor preço por caloria quando comparado aos demais grupos, sugerindo uma vantagem econômica no preparo de refeições no lar em comparação a sua substituição por ultraprocessados. As famílias de maior nível econômico pagaram preço mais elevado por suas aquisições, enquanto as regiões Nordeste, Norte e a área rural pagaram os menores preços. Enquanto alimentos frescos (como carnes, leite, frutas e hortaliças) tendem a custar mais caro que alimentos ultraprocessados, grãos secos (como o arroz e o feijão) despontam como uma alternativa mais econômica para adoção de práticas alimentares saudáveis.

Using food intake records to estimate compliance with the Eatwell Plate dietary guidelines

BACKGROUND

The UK Eatwell Plate is consumer based advice recommending the proportions of five food groups for a balanced diet: starchy foods, fruit and vegetables, dairy foods, nondairy sources of protein and foods and drinks high in fat or sugar. Many foods comprise ingredients from several food groups and consumers need to consider how these fit with the proportions of the Eatwell Plate. This involves disaggregating composite dishes into proportions of individual food components. The present study aimed to match the diets of adults in Scotland to the Eatwell Plate dietary recommendations and to describe the assumptions and methodological issues associated with estimating Eatwell Plate proportions from dietary records.

METHODS

Foods from weighed intake records of 161 females and 151 males were assigned to a single Eatwell group based on the main ingredient for composite foods, and the overall Eatwell Plate proportions of each subject's diet were calculated. Food group proportions were then recalculated after disaggregating composite foods.

RESULTS

The fruit and vegetables and starchy food groups consumed were significantly lower than recommended in the Eatwell Plate, whereas the proportions of the protein and foods high in fat or sugar were significantly higher. Failing to disaggregate composite foods gave an inaccurate estimate of the food group composition of the diet.

CONCLUSIONS

Estimating Eatwell Plate proportions from dietary records is not straightforward, and is reliant on methodological assumptions. These need to be standardised and disseminated to ensure consistent analysis.

Comparative analysis of dietary guidelines in the Spanish-Speaking Caribbean

OBJECTIVE

Dietary guidelines are important education and policy tools to address local nutrition concerns. The current paper presents a comparative analysis of nutrition messages from three Spanish-speaking Caribbean countries (Cuba, Puerto Rico and Dominican Republic) to explore how these dietary guidelines address common public health nutrition concerns, contextualized in different changing food environments and food culture similarities.

DESIGN

Qualitative, comparative analysis of current dietary guideline documents and key recommendations.

RESULTS

Key recommendations were categorized into sixteen themes (two diet-based, ten food-based and four 'other'). Only the Cuban dietary guidelines included diet-based key recommendations. Of the ten food-based key recommendations, only four themes overlapped across the three dietary guidelines (the encouragement of fruits and vegetables, addressing protein sources and fat). Other overlaps were found between dietary guideline pairs, except between Cuba and Puerto Rico. Further analysis revealed differences in levels of specificity and acknowledgement of local dietary patterns and issues, as well as the need to revise the guidelines to account for current scientific advances.

CONCLUSIONS

The present study underscored the importance of context in the framing of dietary advice and the influence of national socio-economic and political situations on nutrition policy and education efforts. The results contribute to inform efforts to improve nutrition communication in the region and among migrant communities.

The future of oats in the food and health continuum

A large body of clinical evidence suggests that the consumption of 3 g or more per d of β-glucan from oats or barley, as part of a diet low in saturated fat and cholesterol, may reduce the risk of CHD. The unique chemical and physical properties of oats and physiological responses to oat consumption contribute to their demonstrated health benefits; other health attributes are still under evaluation. Many of these benefits, such as those associated with a reduced risk of CVD, are codified in health claims by several regulatory agencies, such as the Food and Drug Administration in the USA and the European Food Safety Authority in Europe. Despite these oat–health relationships, an apparent decline in agricultural production, the presence of an array of plant pathogens, and dynamics of climatic conditions may preclude the availability and subsequent consumption of this commodity worldwide. Therefore, it is incumbent on scientists from multiple disciplines to advance research in a spectrum of arenas, including physico-chemical properties of oats, the impact of oats on an array of non-communicable diseases and human microbiome, agricultural practices and environments, and processing technologies that contribute to global food policies.

Knowledge about food classification systems and value attributes provides insight for understanding complementary food choices in Mexican working mothers

Knowledge about mothers' perceptions of food classification and values about complementary feeding is necessary for designing educational and food supply interventions targeted to young children. To determine classification, attributes, and consumption/preparation routines of key complementary foods, 44 mothers of children < 2 y of age in 14 manufacturing businesses were studied. Using 31 key foods, we conducted free-listings, pile-sort, and food attributes exercises. Hierarchical clustering showed that mothers identified nine classes of key foods, including milk derivatives, complements, junk food, infant products, chicken parts, and other meats. From multidimensional scaling, mothers used three primary classification systems: food groups, food introduction stages, and food processing. Secondary classification systems were healthy-junk, heavy-light, hot-cold, good-bad fat, and main dish-complement. Child health and nutrition, particularly vitamin content, were salient attributes. Fruits and vegetables were preferred for initiating complementary feeding on the second month of age. Consumption of guava, mango, and legumes, however, was associated with digestive problems (empacho). Red meats were viewed as cold-type, heavy, and hard, not suitable for young children, but right for toddlers. Chicken liver was considered nutritious but dirty and bitter. Egg and fish were viewed as a vitamin source but potentially allergenic. Mothers valued vitamin content, flavor, and convenience of processed foods, but some were suspicious about expiration date, chemical and excessive sugar content and overall safety of these foods. Mothers' perceptions and values may differ from those of nutritionists and program designers, and should be addressed when promoting opportune introduction of complementary foods in social programs.

Stroke-related knowledge, beliefs, and behaviours of chinese and European canadians: implications for physical therapists

PURPOSE

To improve cross-cultural health education on risk-reducing behaviour change by examining the stroke-related knowledge, beliefs, and behaviours of Chinese Canadians (CCs).

METHODS

Participants (103 first-generation CCs and 101 European Canadians [ECs] representing the dominant cultural group in Canada) completed a cross-sectional questionnaire about knowledge, health behaviours, and beliefs related to stroke.

RESULTS

Compared with ECs, CCs were less aware of risk factors, warning signs, and appropriate responses to stroke in others. Information sources about stroke included mass media, family, and friends. CCs were less likely to smoke and drink alcohol but were also less likely to be physically active or to participate in structured exercise, less likely to have a healthy diet, and more likely to report stress.

CONCLUSIONS

Theoretical dimensions of culture may explain variations in stroke-related knowledge, behaviours, and beliefs between CCs and ECs. Awareness of cultural differences can help physical therapists evaluate clients and appropriately tailor lifestyle-related health education.

The FINUT healthy lifestyles guide: Beyond the food pyramid

The WHO has proposed that health be promoted and protected through the development of an environment that enables sustainable actions at individual, community, national, and global levels. Indeed, food-based dietary guidelines, i.e., food pyramids, have been developed in numerous countries to disseminate nutritional information to the general population. However, wider recommendations are needed, with information on an active healthy lifestyle, not just healthy eating. The objective of the present work is to propose a three-dimensional pyramid as a new strategy for promoting adequate nutrition and active healthy lifestyles in a sustainable way. Indeed, the Iberoamerican Nutrition Foundation (FINUT) pyramid of healthy lifestyles has been designed as a tetrahedron, with its 3 lateral faces corresponding to the facets of food and nutrition, physical activity and rest, and education and hygiene. Each lateral face is divided into 2 triangles. These faces show the following: 1) food-based guidelines and healthy eating habits as related to a sustainable environment; 2) recommendations for rest and physical activity and educational, social, and cultural issues; and 3) selected hygiene and educational guidelines that, in conjunction with the other 2 faces, would contribute to better health for people in a sustainable planet. The new FINUT pyramid is addressed to the general population of all ages and should serve as a guide for living a healthy lifestyle within a defined social and cultural context. It includes an environmental and sustainability dimension providing measures that should contribute to the prevention of noncommunicable chronic diseases.

Contribution to the development of a food guide in Benin: linear programming for the optimization of local diets

OBJECTIVE

Food guides are important tools for nutrition education. While developing a food guide in Benin, the objective was to determine the daily number of servings per food group and the portion sizes of common foods to be recommended.

DESIGN

Linear programming (LP) was used to determine, for each predefined food group, the optimal number and size of servings of commonly consumed foods. Two types of constraints were introduced into the LP models: (i) WHO/FAO Recommended Nutrient Intakes and dietary guidelines for the prevention of chronic diseases; and (ii) dietary patterns based on local food consumption data recently collected in southern Benin in 541 adults. Dietary intakes of the upper tertile of participants for diet quality based on prevention and micronutrient adequacy scores were used in the LP algorithms.

SETTING

Southern area of the Republic of Benin.

SUBJECTS

Local key-players in nutrition (n 30) from the government, academic institutions, international organizations and civil society were partners in the development of the food guide directed at the population.

RESULTS

The number of servings per food group and the portion size for eight age-sex groups were determined. For four limiting micronutrients (Fe, Ca, folate and Zn), local diets could be optimized to meet only 70 % of the Recommended Nutrient Intakes, not 100 %.

CONCLUSIONS

It was possible to determine the daily number of servings and the portion sizes of common foods that can be recommended in Benin with the help of LP to optimize local diets, although Recommended Nutrient Intakes were not fully met for a few critical micronutrients.

Dietary quality and 6-year anthropometric changes in a sample of French middle-aged overweight and obese adults

BACKGROUND

Understanding the role of dietary quality in the progression of adiposity in populations already affected by overweight or obesity is crucial for the guidance of secondary prevention strategies.

OBJECTIVE

To examine the association of diet quality, as reflected by the French Nutrition and Health Programme (Programme National Nutrition Santé, PNNS)-Guideline Score (GS), with 6-year-changes in weight and waist circumference.

DESIGN AND METHODS

Subjects were 1029 male and 450 female participants of the SUplémentation en VItamines et Minéraux AntioXydants (SU.VI.MAX) cohort (1994-2002) with anthropometric variables at baseline and follow-up and available data for estimating diet quality at baseline. We employed analysis of variance and covariance models to investigate anthropometric changes (% of the initial value) by categories of the PNNS-GS, which contains both dietary components and a physical activity component, and of a modified score (mPNNS-GS) containing dietary components only.

RESULTS

In men, a low (<6 points) PNNS-GS was associated with greater 6-year weight gain (adjusted mean: 3.63% [95% confidence interval: 2.87%; 4.39%]) as compared to a high (≥9 points) PNNS-GS (2.10% [1.39%; 2.81%]); p = 0.01. Results for the mPNNS-GS were very similar. In women, no associations between diet scores and weight change were observed. No significant relation between dietary quality and change in waist circumference was present among either men or women.

CONCLUSIONS

These results support a beneficial role of high dietary quality--as characterized by good adherence to official French nutritional guidelines--in secondary obesity prevention, among men.

Validacao de escalas psicossociais para mudanca do consumo de frutas, legumes e verduras

O objetivo foi traduzir, adaptar e testar as propriedades psicométricas de mediadores psicossociais para o consumo de frutas, legumes e verduras. Um questionário multidimensional baseado nos construtos da Teoria Cognitiva Social e do Modelo Transteorético foi administrado em 717 estudantes universitários. Os procedimentos de validação foram: equivalência conceitual, de itens, semântica, operacional, de mensuração e funcional. Análise fatorial exploratória e de estabilidade temporal foram realizadas usando-se o programa SPSS (17.0). Pequenas diferenças entre as versões traduzidas foram observadas e poucas adaptações foram realizadas. A variância explicada observada ficou entre 57,3% e 63,2%, e os valores de α variou de 0,77 a 0,88, apresentando boa consistência interna. A estabilidade temporal média foi boa e todos os construtos se correlacionaram ao estágio de mudança de comportamento (p < 0,05). Todas as etapas de validação foram satisfatórias e consideradas adequadas para aplicação na população.

Diet quality index for healthy food choices

OBJECTIVE: To present a Diet Quality Index proper for dietary intake studies of Brazilian adults. METHODS: A diet quality index to analyze the incorporation of healthy food choices was associated with a digital food guide. This index includes moderation components, destined to indicate foods that may represent a risk when in excess, and adequacy components that include sources of nutrients and bioactive compounds in order to help individuals meet their nutritional requirements. The diet quality index-digital food guide performance was measured by determining its psychometric properties, namely content and construct validity, as well as internal consistency. RESULTS: The moderation and adequacy components correlated weakly with dietary energy (-0.16 to 0.09). The strongest correlation (0.52) occurred between the component 'sugars and sweets' and the total score. The Cronbach's coefficient alpha for reliability was 0.36. CONCLUSION: Given that diet quality is a complex and multidimensional construct, the Diet Quality Index-Digital Food Guide, whose validity is comparable to those of other indices, is a useful resource for Brazilian dietary studies. However, new studies can provide additional information to improve its reliability.

Improving the Comparability of National Estimates of Fruit and Vegetable Consumption for Cross-National Studies of Dietary Patterns

Background

Developing global approaches to the problem of low fruit and vegetable consumption requires cross-nationally comparable estimates of fruit and vegetable consumption. National differences in the definitions of fruits and vegetables and serving size amounts limit the comparability of estimates.

Objectives

To describe national differences in fruit and vegetable definitions, serving size amounts, and how these factors can influence the comparability of fruit and vegetable consumption estimates; and to provide a series of reporting recommendations that could facilitate cross-national studies of fruit and vegetable consumption.

Methods

A comprehensive review of national dietary guidelines, fruit and vegetable definitions, and fruit and vegetable consumption recommendations was undertaken for Canada, the United States, and the United Kingdom.

Results

To improve cross-national comparability, the findings suggest that researchers could report fruit and vegetable consumption separately, provide separate average fruit and vegetable intake amounts, report potato and legume or pulse consumption separately from vegetable consumption, and report consumption of 100% fruit juice separately from fruit consumption.

Conclusions

These four low-cost, high-value additions to conventional research reporting standards will aid in the development of cross-national research on global fruit and vegetable consumption and the design of global policies that can target low fruit and vegetable consumption in populations.

Effectiveness and efficiency of different shapes of food guides

OBJECTIVE

To compare the influence of a food guide's shape on its effectiveness and efficiency to convey nutritional information.

METHODS

A between-subjects experiment was conducted by manipulating the graph's shape (circle, pyramid, or rainbow). Nutrition tasks were used to assess the effectiveness and eye-movement data (number/duration of fixations) to examine the efficiency of the formats. The data were quantitatively analyzed (chi-square, ANOVA).

RESULTS

There were no overall differences between the formats regarding effectiveness and efficiency. However, there were differences between the formats in effectiveness regarding 3 of the 5 nutrition tasks (χ(2)s ≥ 7.044, Ps < .05). Furthermore, viewers' attention was drawn to different parts of the graph, depending on the format.

CONCLUSIONS AND IMPLICATIONS

The results suggest that choosing different formats for practical nutrition communication does not play a major role in effectiveness or efficiency of this communication. However, different parts of the graph are more salient in various food guide formats.

[Esthetic nutrition: body and beauty enhancement through nutritional care]

Nowadays, there is an increasing quest for beauty and the models proposed by fashion goods and service segments, to achieve the perfect body. The standard of beauty corresponds to a thin body, without considering health aspects. The number of women who go on diets to control weight is increasing; and taking this into consideration the objective of this study is to conduct a bibliographical review and extract data on esthetics and body image to support the practice of nutritional care. Socio-cultural aspects, which motivate the quest for the perfect body, as well as body, beauty, esthetics, nutritional counseling and cognitive behavior therapy were examined in this survey. On the basis of this work, it is possible to conclude that the continuing obsession with the body may lead the person to go on diets and other drastic methods to control weight, such as surgical procedures. In this respect, nutritional care is far more than merely recommending a standard diet or giving information, as it represents providing an effective model for nutritional reeducation, prioritizing improvement in the style and quality of life. This article provides data about enhancing esthetics and beauty by means of appropriate nutrition.

How much is enough? Tablespoon per year of age approach meets nutrient needs for children

BACKGROUND

Adults often ask health professionals for guidance on offering the appropriate serving sizes for young children and little research is available on whether serving size approaches meet children's nutrient needs.

OBJECTIVE

Determine whether three serving size approaches for young children meet dietary standards for nutrient adequacy.

DESIGN

We examined nutrient contents of three serving size approaches for children ages 2-5 years of age: 1 tablespoon per year of age (T/y), MyPyramid, and Child and Adult Care Food Program. Nutrient content of the three approaches were compared to the Estimated Energy Requirements (EER), Estimated Average Requirement (EAR), or Adequate Intake (AI) for each year of age for males and females; Analysis of Variance identified differences in nutrient content among the three approaches.

RESULTS

Young children's nutrient requirements were met for most nutrients by all approaches. However, the recommendation for vitamin E, potassium, and fat were not met by any approach, for any year, for either girls or boys. Energy content of the T/y serving size approach was below the EER for each year of age and for both sexes but still met minimal vitamin and mineral needs.

CONCLUSION

Health professionals can feel comfortable using any of the three approaches. However, the T/y approach is a more graduated serving size approach, may be more consistently age appropriate for young children, and may be implemented more easily by adults.

Determinants of changes in dietary patterns among Chinese immigrants: a cross-sectional analysis

BACKGROUND

Chinese individuals who have immigrated to a Western country initially tend to have a lower risk of cardiovascular disease (CVD) compared to people who are already living there. Some studies have found, however, that CVD risk increases over time in immigrants and that immigration to a western country is associated with changes in dietary patterns. This could have unfavourable effects on the risk of CVD. There is limited knowledge on the food patterns, awareness and knowledge about healthy nutrition among Chinese immigrants. The objective for this study is to explore changes in food patterns, and levels of awareness and knowledge of healthy nutrition by length of residence among Chinese immigrants to Canada.

METHODS

120 Chinese individuals born in China but currently living in Canada completed an assessment on socio-demographic characteristics, changes in dietary patterns and variables of awareness and knowledge about healthy foods. With ordinal logistic regression the associations between the quartiles of length of residence and dietary patterns, variables of awareness and knowledge about healthy foods were explored, adjusting for age, sex, education and body mass index.

RESULTS

More than 50% of the participants reported increasing consumption of fruits and vegetables, decreasing the use of deep-frying after immigration. Increased awareness and knowledge about healthy foods was reported by more than 50% of the participants. Ordinal regression indicated that Chinese immigrants who lived in Canada the longest, compared to Chinese immigrants who lived in Canada the shortest, consumed significant greater portion sizes (OR: 9.9; 95% CI: 3.11 - 31.15), dined out more frequently (OR: 15.8; 95% CI: 5.0 - 49.85), and consumed convenience foods more often (OR: 3.5; 95% CI: 1.23 - 10.01).

CONCLUSIONS

Chinese immigrants reported some favourable changes in their dietary intake and greater awareness and more knowledge about healthy foods after immigration. However, an increase in portion size, an increased frequency of dining out and an increased consumption of convenience foods could indicate some unfavourable changes. These results suggest that health promotion strategies should build on the observed benefits of improved nutritional knowledge and target areas of portion size and convenience eating.

A new classification of foods based on the extent and purpose of their processing

This paper describes a new food classification which assigns foodstuffs according to the extent and purpose of the industrial processing applied to them. Three main groups are defined: unprocessed or minimally processed foods (group 1), processed culinary and food industry ingredients (group 2), and ultra-processed food products (group 3). The use of this classification is illustrated by applying it to data collected in the Brazilian Household Budget Survey which was conducted in 2002/2003 through a probabilistic sample of 48,470 Brazilian households. The average daily food availability was 1,792 kcal/person being 42.5% from group 1 (mostly rice and beans and meat and milk), 37.5% from group 2 (mostly vegetable oils, sugar, and flours), and 20% from group 3 (mostly breads, biscuits, sweets, soft drinks, and sausages). The share of group 3 foods increased with income, and represented almost one third of all calories in higher income households. The impact of the replacement of group 1 foods and group 2 ingredients by group 3 products on the overall quality of the diet, eating patterns and health is discussed.

Percepção de responsáveis e recreadores sobre diferentes representações gráficas de guia alimentar para crianças de dois a três anos

OBJETIVO: Conhecer a percepção de responsáveis e recreadores sobre diferentes representações gráficas de guia alimentar para crianças de dois a três anos de idade. MÉTODOS: Estudo qualitativo feito com seis recreadores e 12 responsáveis por crianças de dois a três anos de uma creche pública do Rio de Janeiro. Um questionário sociodemográfico foi aplicado e uma entrevista semi-estruturada, realizada. Mostraram-se cinco representações gráficas (roda, pirâmide, arco-íris, trenzinho e prato) para que os participantes respondessem a perguntas sobre conhecimento dos grupos alimentares, conceito de nutrição (proporcionalidade/moderação e variedade), alimentação saudável e escolhessem a figura que melhor representasse a alimentação saudável. Procedeu-se, então, à análise de conteúdo. RESULTADOS: A maioria dos responsáveis (92%) percebeu o conceito de grupos alimentares com clareza, pois reportou que os guias estavam divididos por alimentos e estes agrupados de acordo com os nutrientes. Os participantes compreenderam o conceito de proporcionalidade/moderação, porém o formato hierarquizado da pirâmide causou dificuldade de interpretação, já que apontaram os grupos no topo como os mais importantes. Os participantes salientaram a importância de incluir na dieta alimentos de todos os grupos, porém o conceito de variedade intragrupo foi compreendido por apenas dois participantes. Os entrevistados elegeram a roda como o ícone que melhor representava a alimentação saudável. CONCLUSÕES: Na elaboração de um guia alimentar, deve-se levar em consideração o entendimento dos conceitos nutricionais por parte dos indivíduos para que os objetivos propostos possam ser atingidos.

Desenvolvimento de guias alimentares em diversos países

Os guias dietéticos baseados nos alimentos têm objetivo de favorecer a educação nutricional, utilizando termos que sejam compreensíveis, simples e claros para a maioria dos consumidores e indicando as modificações necessárias nos padrões alimentares. Este trabalho foi realizado com o objetivo de apresentar uma revisão da literatura sobre o desenvolvimento dos guias alimentares em vários países. Para tanto, foi realizado um levantamento bibliográfico no período de 1991 a 2006 nas bases de dados Medline e Lilacs, utilizando como palavras-chave "guia alimentar", "guia dietético" e "desenvolvimento de guia dietético" com o intuito de aprofundar os seguintes itens: elaboração, avaliação, implantação e problemas metodológicos relacionados ao desenvolvimento dos mesmos. Desde 1996, vêm sendo publicadas orientações pelo Comite de Alimentação e Nutrição/Organização Mundial de Saúde para elaboração dos guias alimentares e vários países os desenvolveram de acordo com essas recomendações, apesar dos diversos problemas metodológicos enfrentados. Após o desenvolvimento dos guias alimentares, os maiores desafios são a implantação e a avaliação. Dentre as estratégias para sua divulgação destaca-se a elaboração de ferramentas de educação nutricional, tais como: representação gráfica, folder, apostila e pôster. Com relação à avaliação dos guias alimentares, poucos países realizaram pesquisas abordando o conhecimento e o entendimento dos consumidores. Conclui-se que o processo de desenvolvimento dos guias alimentares é complexo e é necessário realizar um planejamento para sua implantação e avaliação, esta última devendo se voltar tanto ao entendimento como ao impacto sobre a saúde da população.

Developing food-based dietary guidelines to promote healthy diets and lifestyles in the Eastern Caribbean

Obesity, cardiovascular diseases, and diabetes are becoming leading causes of morbidity and mortality in the Eastern Caribbean countries of St. Vincent and the Grenadines, Saint Lucia, Grenada, and Dominica. To promote healthful diets and lifestyles and encourage behavioral changes, Food-Based Dietary Guidelines (FBDG) were developed for the general population in each of these countries. This paper reports on the comprehensive process of developing the guidelines through consensus building among stakeholders, technical assessments and priority setting, and use of qualitative methods to field test messages to ensure public understanding and motivation. Nutritionists in each country received training and support from the Food and Agriculture Organization and the Pan American Health Organization's nutritionists.
