Children are not consuming the recommended amounts of fruit and vegetables. Repeated visual exposure, modelling, and rewards have been shown to be effective at increasing vegetable acceptance in ...young children. The aim of this study was to assess the effectiveness of an evidence-based mobile application (Vegetable Maths Masters) which builds on these principles to increase children's liking and acceptance of vegetables. Seventy-four children (37 male, 37 female) aged 3–6 years old were randomised to play with either the vegetable app or a similar control app that did not include any foods. Children played their allocated game for 10 min. Liking and acceptance of the vegetables used in Vegetable Maths Masters (carrot and sweetcorn) and other vegetables which were not used in the game (yellow pepper and tomato) were measured pre- and post-play in both groups. Parents provided data about their child's food fussiness and previous exposure to the foods being used. Children who played with the Vegetable Maths Masters app consumed significantly more vegetables after playing with the app and reported significant increases in their liking of vegetables, relative to the control group. The effect of the Vegetable Maths Masters app on the change in consumption of vegetables was mediated by the change in liking of vegetables. These findings suggest that evidence-based mobile apps can provide an effective tool for increasing children's liking and consumption of vegetables in the short-term. Further work is now required to establish whether these effects are maintained over time.
•A vegetable based maths game was developed to support vegetable accetpance using the principles of repeated exposure, modelling, and rewards.•Playing with the Vegetable Maths Maters app for 10 min resulted in significant increases in liking and intake of vegetables in 3–6 year old children.•Increases in consumption of vegetables were explained by increases in liking for vegetables after children played with the app.•Future research is needed to explore the effectiveness of such games in the longer term.
Home food procurement (HFP) (i.e. gardening, fishing, foraging, hunting, backyard livestock and canning) have historically been important ways that people obtain food. Recently, some HFP activities ...have grown (e.g. gardening), while other activities (e.g. hunting) have become less common in the United States. Anecdotally, COVID-19 has sparked an increase in HFP evidenced by increased hunting licenses and shortages in seeds and canning supplies. HFP may have positive benefits for food security and diet quality, though research beyond gardening is especially limited in high-income countries.
We examine HFP activities since the COVID-19 pandemic began, and their relationship to food security and dietary quality using multivariable logit models and matching analysis with a statewide representative survey (n = 600) of residents of Vermont, United States.
We find 29% of respondent households classified as food insecure since COVID-19, and higher prevalence of food insecurity among those experiencing a negative job change since COVID-19, households earning less than $50,000 annually, Hispanic and multi-race respondents. Nearly 35% of respondents engaged in HFP activities since the COVID-19 pandemic began; the majority of those gardened, and more than half pursued HFP activities more intensely than before the pandemic or for the first time. Food insecure households were more likely to pursue HFP more intensely, including more gardening, fishing, foraging, and hunting. Respondents who were food insecure, Black, Indigenous, People of Color, those with a negative job disruption, and larger households all had greater odds of increased intensity of HFP during the COVID-19 pandemic. HFP was significantly associated with eating greater amounts of fruits and vegetables; however, this effect was only significant for food secure households.
Overall, these results suggest that HFP activities have increased since the start of the COVID-19 pandemic, and may be an important safety net for food insecure households. However, HFP for food insecure households does not translate into the same higher fruit and vegetable intake as found among food secure HFP households, suggesting this population may be trying to maintain intake, or that they may have potential important resource or technical assistance needs. Long-term, HFP activities may have important food security and diet quality impacts, as well as conservation implications, which should be more thoroughly explored. Regardless, the increased interest and intensity of HFP demonstrates opportunities for educational and outreach efforts.
Mobile markets (MM) bring affordable, quality, healthy foods to high-need, low-food access communities. However, little is known about food insecurity of MM customers. This manuscript evaluates food ...insecurity prevalence in MM customers and assesses associations between food insecurity and MM use, food-related characteristics and behaviors, and fruit and vegetable (FV) intake. Customers (N = 302) completed cross-sectional surveys in summer 2019 that assessed: food security, food availability, cooking attitude, self-efficacy for healthy cooking, self-efficacy for cooking and eating FV, social connectedness, and FV intake. Descriptive and multivariate analyses were used to describe and assess associations with food insecurity and FV intake. Results show most MM customers were food insecure (85%). In logistic regression models adjusted for sociodemographic characteristics, long-term MM use (OR = 0.77, CI = 0.60–0.997), access to affordable, quality foods (OR = 0.81, CI = 0.71–0.93), and self-efficacy for both cooking healthy foods (OR = 0.88, CI = 0.80–0.97) and cooking and eating FV (OR = 0.90, CI = 0.82–0.98) were associated with lower odds of food insecurity; negative cooking attitudes (OR = 1.12, CI = 1.02–1.24) were associated with higher odds of food insecurity. Being food insecure (β = −1.37, SE=0.43, p < 0.01) was associated with poorer FV intake; this association attenuated slightly (β = −1.22, SE=0.43, p < 0.01) when length of MM use was added to the general linear model, which was also associated with higher fruit and vegetable intake (β = 0.26, SE=0.10, p = 0.01). Results suggest the MM reaches customers experiencing high levels of food insecurity and long-term MM use is associated with lower food insecurity and higher FV intake. Relationships between food insecurity and several food characteristics/behaviors provide insight for potential targets for wrap-around interventions to address food insecurity among customers. Findings suggest longitudinal evaluation of the MM's impact on food security and other food-related characteristics/behaviors is warranted.
University students are at increased risk for both food insecurity and suboptimal fruit and vegetable (F/V) intake. Campus food pantries (CFP) have been a common intervention in response to student ...food insecurity, but there have been few evaluations of the effectiveness of this strategy on improving students' dietary intake.
To examine differences in the frequency of F/V intake by food security status, and whether the number of monthly CFP visits was associated with frequency of F/V intake among university students who were CFP clients.
Cross-sectional PARTICIPANTS: The study population included 1,188 university students across the 10-campus University of California system who had accessed their CFP or Basic Needs Center.
United States Department of Agriculture (USDA) 6-item short food security module, monthly CFP visits, and self-reported frequency of F/V intake (daily).
T-tests were performed to compare differences in mean daily frequency of F/V intake by food security status. Generalized linear models were used to examine associations between monthly CFP visits and mean daily frequency of F/V intake. Using a post hoc Wald test, an interaction term (monthly CFP visits × food security status) was included to the models to determine whether food security status modified associations.
Students experiencing food insecurity consumed total F/V 0.48 fewer times per day compared with students who were food secure (2.64 ± 2.11 vs 3.12 ± 2.01; P < .001). Among students experiencing food insecurity, each monthly CFP visit was associated with higher daily frequencies of intake for total F/V (β = 0.06), whole fruit (β = 0.03), 100% fruit juice (β = 0.01), and leafy greens (β = 0.01); however, no associations were found among the food-secure group.
Findings suggest that CFPs may be supporting students in need of nutritional assistance increase their daily frequency of F/V intake. Future studies are needed to validate these findings to inform investment in campus food pantries and support university students in need of nutritional assistance.
•100 student consumers received convenient or regular vegetables for one week.•Convenient vegetable products may increase vegetable intake among young consumers.•Convenient vegetable products were ...experienced and used differently than regular vegetables.•Student consumers were not willing to buy or pay more for convenient vegetable products.
Current food trends such as healthy eating, plant-based diets and sustainability encourage consumers to eat more vegetables. However, it is a challenge for many, including the younger generations, to meet the dietary recommendations regarding vegetable intake. The purpose of this study was to investigate if vegetable convenience products can increase the daily intake of vegetables among young consumers.A total of 100 participants were randomly allocated to receive either regular or convenience vegetables for a week and filled in questionnaires about vegetable use and consumption before after the intervention. Results showed that participants who received convenience vegetable products significantly increased their daily vegetable consumption by 19% (p = 0.005), but there was no significant difference between the groups during the intervention period. Furthermore, convenience vegetable products were used and perceived differently from regular vegetables. It was found that especially the preparation of the convenient vegetable products had an impact on how the products were perceived. Participants indicated that they were not willing to buy or pay more for convenience in relation to vegetables. In conclusion, convenience vegetable products may increase vegetable intake among young consumers. However, this specific consumer group may find barriers within their values regarding food, consumerism and sustainability, whichprevent them from buying convenience food products.
Poor nutritional habits are linked to higher perceived stress, but the relationship between fruit and vegetable (FV) intake and stress is uncertain. The primary aim of this cross-sectional study was ...to explore the relationship between FV intake and perceived stress in a population-based cohort of men and women aged ≥25 years from the Australian Diabetes, Obesity and Lifestyle (AusDiab) Study. A secondary aim was to investigate the relationship between serum carotenoids, biomarkers of FV intake, and perceived stress.
In Australian men and women, dietary intake was assessed using a Food Frequency Questionnaire in 1999–2000 (n = 8689). Perceived stress was assessed using a validated Perceived Stress Questionnaire PSQ index values ranging from 0 (lowest) to 1 (highest). Serum carotenoids were measured in a subset of participants (n = 1187) using high-performance liquid chromatography. Multivariable-adjusted linear and logistic regression were performed to investigate the associations between FV intake and perceived stress.
Mean age of participants was 47.4 (SD 14.1) years (49.8% females). Participants with the highest intakes of FV had 10% lower PSQ index values than those with the lowest intake Q4: 0.27 ± 0.004 vs. Q1: 0.30 ± 0.004 (mean ± SE), p = 0.004. Similar associations were found for fruits and vegetables, analysed separately. In subgroup analyses higher FV intake was associated with lower perceived stress in the middle-aged adults ≥45-<65 years (p = 0.004), but not in the younger (<45 years) and older participants (≥65 years). Higher FV intake was also significantly associated with lower perceived stress in men (p = 0.009) and women (p = 0.012), separately. Serum carotenoid levels were inversely associated with perceived stress before, but not after adjusting for age and other confounding factors.
In Australian adults, higher FV intake was associated with lower perceived stress, particularly in the middle-aged adults. These findings support current recommendations that fruit and vegetables are essential for health and well-being.
Behavioral economics strategies implemented within social marketing campaigns improve eating behavior.
To identify which behavioral economics strategies in social marketing messages particularly ...messengers, norms, and commitments will promote low-income Louisiana residents to add more vegetables to meals.
Full profile traditional conjoint analysis survey with single concept ratings.
Purposive sample of low-resource Louisiana residents (N = 213)
Online survey.
Participants rated randomized concepts that featured a messenger and a message.
Ratings (one to nine) of likelihood to add vegetables to meals.
A model of ratings was generated using mixed-effects multiple regression, which accounted for repeated measurement of participants. Interactions of variables and covariates were modeled.
There was a significant main effect of the messenger variable (P = 0.02) and main effect of the message variable (P = 0.008). Pairwise comparisons demonstrated differences between friend (μ (predicted mean) = 6.80) and mother (μ = 7.06; P = 0.03) as well as friend and normal-weight doctor (μ = 7.03; P = 0.04). Pairwise comparisons demonstrated differences between descriptive norm (μ = 6.79) and grocery list precommitment (μ = 7.02; P = 0.05) along with descriptive norm and injunctive norm (μ = 6.98; P = 0.04). Covariate models demonstrated main effects of race (P = 0.006) and sex (P = 0.0001). There was significant variation in the message variable and frequency of vegetable intake interaction (P = 0.01).
Both message and messenger variables predicted the likelihood to add vegetables to meals. Race and sex influenced ratings to add vegetables. As reported vegetable consumption increased, behavioral economics messages improved the likelihood to add vegetables to meals. Behavioral economic approaches are well suited to social marketing messages that aim to promote healthy eating behavior in low-income LA residents.
ObjectiveThe role of diet in multiple sclerosis (MS) course remains largely unknown. Children with MS have a higher relapse rate compared with MS in adults. Thus, studying the effect of diet on ...relapse rate in this age group is likely to provide more robust answers.MethodsThis is a multicentre study done at 11 paediatric MS centres in the USA. Patients with relapsing-remitting MS (RRMS) or clinically isolated syndrome (CIS) with disease onset before 18 years of age and duration of less than 4 years were included in this study. Dietary intake during the week before enrolment was assessed with the validated Block Kids Food Screener. The outcome of the study was time from enrolment to the next relapse. 219 patients with paediatric RRMS or CIS were enrolled. Each 10% increase in energy intake from fat increased the hazard of relapse by 56% (adjusted HR 1.56, 95% CI 1.05 to 2.31, p=0.027), and in particular each 10% increase in saturated fat tripled this hazard (adjusted HR: 3.37, 95% CI 1.34 to 8.43, p=0.009). In contrast, each additional one cup equivalent of vegetable decreased the hazard of relapse by 50% (adjusted HR: 0.50, 95% CI 0.27 to 0.91, p=0.024). These associations remained with mutual adjustment and persisted when adjusting for baseline 25(OH) vitamin D serum level. Other studied nutrients were not associated with relapse.ConclusionsThis study suggests that in children with MS, high energy intake from fat, especially saturated fat, may increase the hazard to relapse, while vegetable intake may be independently protective.
In Japan, the amount of vegetable intake in young adults, especially at breakfast, is low. We aimed to examine the factors associated with vegetable intake at breakfast among young adults. In 2016, a ...self-administered questionnaire survey was conducted at a Japanese university. The questionnaire measured the frequency of ≥70 g vegetable intake at breakfast, lifestyle, eating habits, environmental factors, knowledge and attitudes (including the variable “Perceived behavior control (PBC)”, from the Theory of Planned Behavior). The data of 1,455 male students who usually ate breakfast were analyzed. They were divided into two groups based on the median of the frequency of vegetable intake and the above factors were compared using a chi-squared test by living condition. The significant factors were subsequently entered into a logistic regression analysis as independent variables. Eating breakfast with family or friends and PBC were positively associated with vegetable intake in students living with their family. Often doing one’s own cooking, having knowledge about a well-balanced diet, and PBC were positively associated with vegetable intake in students living alone. Along with PBC, different factors pertaining to an individual’s living condition may need to be considered to increase vegetable intake at breakfast.
