Diet-related diseases are the leading cause of morbidity and mortality in the USA. While the critical aspects of a healthy diet are well known, the relationship between community-based, teaching kitchen education and dietary behaviours is unclear. We examined the effect of a novel culinary medicine education programme on Mediterranean diet adherence and food cost savings.

Families were randomised to a hands-on, teaching kitchen culinary education class (n = 18) or non-kitchen-based dietary counselling (n = 23) for 6 weeks. The primary outcome was adherence to the validated nine-point Mediterranean diet score, and the secondary outcome was food cost savings per family.

The Goldring Center for Culinary Medicine, a community teaching kitchen in New Orleans.

Families (n = 41) of at least one child and one parent.

Compared with families receiving traditional dietary counselling, those participating in hands-on, kitchen-based nutrition education were nearly three times as likely to follow a Mediterranean dietary pattern (OR 2·93, 95% CI 1·73, 4·95; P  <  0·001), experiencing a 0·43-point increase in Mediterranean diet adherence after 6 weeks (B  =  0·43; P  <  0·001). Kitchen-based nutrition education projects to save families $US 21·70 per week compared with standard dietary counselling by increasing the likelihood of consuming home-prepared v. commercially-prepared meals (OR 1·56, 95% CI 1·08, 2·25; P  =  0·018).

Community-based culinary medicine education improves Mediterranean diet adherence and associates with food cost savings among a diverse sample of families. Hands-on culinary medicine education may be a novel evidence-based tool to teach healthful dietary habits and prevent chronic disease.

To understand non-adherence to medically recommended diets among Mayans with diabetes.

Using partially sequential mixed methods, questionnaires, semi-structured brief and in-depth interviews were applied. Questionnaire data were analysed with Pearson’s χ2 and Student’s t tests and qualitative interviews with grounded theory microanalysis.

Rural, predominantly Mayan communities in Chiapas, Quintana Roo and Yucatan, Mexico, 2008–2012.

Purposive sample of Mayans with type 2 diabetes; using public health care; 168 women and twenty-seven men; age 21–50+ years.

Participants understood diabetes as caused by negative emotions, divine punishment, revenge via spells, chemicals in food and high sugar/fat consumption. Eliminating corn, pork, sugary beverages and inexpensive industrialized foods was perceived as difficult or impossible. More Mayans reporting not understanding physician instructions (30 v. 18 %) reported difficulty reducing red meat consumption (P = 0·051). Non-adherence was influenced by lack of patient–provider shared knowledge and medical recommendations misaligned with local culture. Men whose wives prepared their meals, women who liked vegetables and young adults whose mothers prepared their meals reported greater adherence to dietary recommendations. Partial adherents said it made life tolerable and those making no physician-recommended dietary changes considered them too restrictive (they meant ‘starving to death’). Over half (57 %) of participants reported non-adherence; the two principal reasons were dislike of recommended foods (52·5 %) and high cost (26·2 %).

Adherence to dietary regimens in diabetes treatment is largely related to social and cultural issues. Taking cultural diversity, food preferences, local food availability and poverty into consideration is essential when developing health-promotion activities related to diabetes.

To explore the perceptions of soldiers participating in a US Army Office of The Surgeon General’s worksite health promotion programme (WHPP) on the local food environment within their campus-style workplace.

Focus groups were conducted to evaluate the perceived effectiveness of the WHPP implementation. Further exploration of focus group data through thematic analysis focused on perceived contributions of the military campus-style food environment to soldiers’ nutrition behaviours.

Three US Army installations located in the continental USA.

Active duty soldiers (n 366) participating in one of the fifty-eight focus groups.

Soldiers shared a common belief of self-discipline and personal responsibility as the foothold to nutrition behaviour change. Soldiers described aspects of the military campus-style food environment as factors impeding achievement of optimal nutrition. Collectively, soldiers perceived the proximity and density of fast-food restaurants, lack of healthy alternatives on the installation and the cost of healthy food as inhibitors to choosing healthy foods. Overwhelmingly, soldiers also perceived time constraints as a factor contributing to unhealthy food choices.

Although nutrition behaviour is individually driven, soldiers perceived the military campus-style food environment inhibits healthy decision making. Nutrition programming in military WHPP must integrate food environment changes to improve soldiers’ nutrition behaviour outcomes. Applicable to the military, food choice behaviour studies suggest environmental changes must be appealing to young adults. Considerations for environmental changes should include an increased portion size for healthy options, broadened use of soldiers’ daily food allowances on local produce and increased availability of grab-and-go options.

To examine score validity and reliability of a child version of the twenty-one-item Three-Factor Eating Questionnaire (CTFEQ-R21) in a sample of Canadian children and adolescents and its relationship with BMI Z-score and food/taste preferences.

Cross-sectional study.

School-based.

Children (n 158), sixty-three boys (mean age 11·5 (sd 1·6) years) and ninety-five girls (11·9 (sd 1·9) years).

Exploratory factor analysis revealed that the CTFEQ-R21 was best represented by four factors with item 17 removed (CFFEQ-R20), representing Cognitive Restraint (CR), Cognitive Uncontrolled Eating (UE 1), External Uncontrolled Eating (UE 2) and Emotional Eating (EE), accounting for 41·2 % of the total common variance with good scale reliability. ANOVA revealed that younger children reported higher UE 1 and CR scores than older children, and boys who reported high UE 1 scores had significantly higher BMI Z-scores. Children with high UE 1 scores reported a greater preference for high-protein and -fat foods, and high-fat savoury (HFSA) and high-fat sweet (HFSW) foods. Higher preference for high-protein, -fat and -carbohydrate foods, and HFSA, HFSW and low-fat savoury foods was found in children with high UE 2 scores.

The study suggests that the CFFEQ-R20 can be used to measure eating behaviour traits and associations with BMI Z-score and food/taste preferences in Canadian children and adolescents. Future research is needed to examine the validity of the questionnaire in larger samples and other geographical locations, as well as the inclusion of extraneous variables such as parental eating or socio-economic status.

To examine consumers’ perceptions of their food environments, their food consumption patterns and preferences, and to better understand the attributes of foods that are available within food environments in Myanmar.

An exploratory mixed-methods study using a combination of focus group discussions, market and consumer surveys.

Four study settings in Myanmar were included: an upper-income township of Yangon; a lower-income township of Yangon; a middle-income township in the southern Myanmar town of Dawei; and a lower-income village in the country’s dry zone of Magway.

Thirty-two women participated in the focus groups discussions, twenty market surveys were conducted and 362 consumers (both men and women) completed food consumption surveys.

Focus group participants indicated that the availability of a diverse range of foods had increased over time, while the quality of foods had decreased. Health was seen primarily through the lens of food safety and there was an overall lack of knowledge about which foods were more or less healthy. Consumers preferred fruits, vegetables and red meat compared with highly processed snack foods/beverages. Although consumers reported low intakes of highly processed snack foods, Burmese street food was consumed in high quantities. The market surveys suggested that fresh, minimally processed and highly processed foods were available at all markets across the study settings.

Consumers are exposed to a variety of foods, of varying quality, within their food environments in Myanmar. Interventions aimed at increasing consumer knowledge regarding healthy diets and improving food safety are needed.

To elucidate the factors influencing food intake and preferences for potential nutritional supplements to treat mild and moderate malnutrition among adult people living with HIV (PLHIV).

Qualitative research using in-depth interviews with a triangulation of participants and an iterative approach to data collection.

The study was conducted in a health clinic of rural Chilomoni, a southern town of Blantyre district, Malawi.

Male and female participants, aged 18–49 years (n 24), affected by HIV; health surveillance assistants of Chilomoni clinic (n 8).

Six themes emerged from the in-depth interviews: (i) PLHIV perceived having a poor-quality diet; (ii) health challenges determine the preferences of PLHIV for food; (iii) liquid–thick, soft textures and subtle natural colours and flavours are preferred; (iv) preferred organoleptic characteristics of nutritional supplements resemble those of local foods; (v) food insecurity may contribute to intra-household sharing of nutritional supplements; and (vi) health surveillance assistants and family members influence PLHIV’s dietary behaviours. No differences by sex were found. The emergent themes were corroborated by health surveillance assistants through participant triangulation.

In this setting, a thickened liquid supplement, slightly sweet and sour, may be well accepted. A combination of quantitative and qualitative methods for data collection should follow to further develop the nutritional supplement and to fine tune the organoleptic characteristics of the product to the taste and requirements of PLHIV. Results of the present study provide a first approach to elucidate the factors influencing food intake and preferences for potential nutritional supplements among adult PLHIV.

Analysing dietary data to capture how individuals typically consume foods is dependent on the coding variables used. Individual foods consumed simultaneously, like coffee with milk, are given codes to identify these combinations. Our literature review revealed a lack of discussion about using combination codes in analysis. The present study identified foods consumed at mealtimes and by race when combination codes were or were not utilized.

Duplicate analysis methods were performed on separate data sets. The original data set consisted of all foods reported; each food was coded as if it was consumed individually. The revised data set was derived from the original data set by first isolating coded foods consumed as individual items from those foods consumed simultaneously and assigning a code to designate a combination. Foods assigned a combination code, like pancakes with syrup, were aggregated and associated with a food group, defined by the major food component (i.e. pancakes), and then appended to the isolated coded foods.

Healthy Aging in Neighborhoods of Diversity across the Life Span study.

African-American and White adults with two dietary recalls (n 2177).

Differences existed in lists of foods most frequently consumed by mealtime and race when comparing results based on original and revised data sets. African Americans reported consumption of sausage/luncheon meat and poultry, while ready-to-eat cereals and cakes/doughnuts/pastries were reported by Whites on recalls.

Use of combination codes provided more accurate representation of how foods were consumed by populations. This information is beneficial when creating interventions and exploring diet–health relationships.

The objective was to investigate parents’ motives for selecting foods for their children and the associations between these motives and children’s food preferences.

Cross-sectional survey. A modified version of the Food Choice Questionnaire was used to assess parents’ food choice motives. Parents also reported children’s liking/disliking of 176 food and beverage items on 5-point Likert scales. Patterns of food choice motives were examined with exploratory principal component analysis. Associations between motives and children’s food preferences were assessed with linear regression while one-way and two-way ANOVA were used to test for sociodemographic differences.

Two Australian cities.

Parents (n 371) of 2–5-year-old children.

Health, nutrition and taste were key motivators for parents, whereas price, political concerns and advertising were among the motives considered least important. The more parents’ food choice for their children was driven by what their children wanted, the less children liked vegetables (β =−0·27, P<0·01), fruit (β=−0·19, P<0·01) and cereals (β=−0·28, P<0·01) and the higher the number of untried foods (r=0·17, P<0·01). The reverse was found for parents’ focus on natural/ethical motives (vegetables β=0·17, P<0·01; fruit β=0·17, P<0·01; cereals β=0·14, P=0·01). Health and nutrition motives bordered on statistical significance as predictors of children’s fruit and vegetable preferences.

Although parents appear well intentioned in their motives for selecting children’s foods, there are gaps to be addressed in the nature of such motives (e.g. selecting foods in line with the child’s desires) or the translation of health motives into healthy food choices.

To investigate test–retest reliability of primary-school children's reports of food preferences and to investigate agreement with parental reports.

Children completed an online test and retest, one to two weeks later, during school hours; parents completed a paper-and-pencil or an online questionnaire at home. The children's preferences questionnaire contained 148 food items, reduced to twelve scales; the parental questionnaire contained seventy-eight items reduced to nine scales.

Children of fourteen primary schools in Belgium-Flanders.

In total 572 children participated; test–retest data were available for 354 children, children's tests could be matched to 362 parental reports.

Test–retest intraclass correlations were on average 0·73, ranging between 0·62 and 0·86; correlations between children's and parents’ reports were on average 0·50, ranging between 0·32 and 0·62. Retest preferences were significantly higher for more than half of the scales. Children reported higher preferences than their parents for milk & milk products, fruit and soft drinks, while parents reported higher preferences for bread & breakfast cereals, meat, snacks and sauces.

The results indicate that the test–retest stability was good; however, agreement between parents and children was rather low to moderate.

Studies indicate that food and beverages typically marketed to children are products high in fat, sugar and salt. LazyTown is an entertainment brand with a focus on healthy lifestyle, aimed at making health education entertaining. The aim of the present study was to assess whether children perceive food to taste better with a LazyTown label on the wrapping compared with the original packaging.

Five pairs of identical food and beverage samples were introduced. We aimed to select healthy food and beverages from various food groups. Preference for the LazyTown food was coded as +1, no preference 0 and preference for the original food as −1. An average ‘preference score’ was calculated for each subject by adding up the answers.

Three pre-schools in the Greater Reykjavik area, Iceland.

Subjects were pre-school children aged 3·5 to 6 years (n 66).

Most children answered correctly that there was no difference in the taste between the two identical food samples. However, between 27 and 42 % (depending on the product) of children preferred the taste of LazyTown food and beverages despite the fact that the test food was identical. The mean preference score was 0·29 (sd 0·32, median 0·20, 95 % CI 0·21, 0·38).

Our findings add to past research by demonstrating children’s preferences for child-oriented wrappings rather than regular wrapping. It might be suggested that popular brands could be useful to promote healthy eating among young children along with other actions.
