Variety Salience and Enjoyment of Repetitiously Consumed Foods: a Field Experiment.

BACKGROUND: The formation of healthy eating habits is supported by repeatedly eating specific foods, but repetition can also reduce enjoyment of those foods. Making the variety in one's diet salient increases enjoyment of repetitiously consumed foods in a lab setting. Therefore, in a longitudinal field experiment, we tested a brief intervention to remind participants of the variety in their diet. We hypothesized that increasing salience of dietary variety would prevent declines in enjoyment of the food and increase the likelihood that participants would be willing to eat the food again later. METHOD: Participants (n = 139) ate a granola bar each day for 2 weeks. Before eating it, participants randomly assigned to the treatment condition recalled other recently consumed foods (to increase salience of dietary variety). Control subjects recalled variety in an unrelated domain (music). Participants reported their enjoyment of the granola bar after they ate it each day, and in a lab session after the study ended, the number of granola bars they took from a selection of snacks was counted. RESULTS: Self-reported feelings of enjoyment declined steadily, and contrary to our first hypothesis, increasing salience of dietary variety did not prevent this decline. Increasing salience of dietary variety did increase the likelihood that participants would choose to take the same kind of granola bar 2 weeks later. CONCLUSION: Brief exercises that make variety in one's diet more salient may not prevent reductions in enjoyment of a repetitiously consumed food, but may still support continued consumption of the food.

An in-home intervention of parent-implemented strategies to increase child vegetable intake: results from a non-randomized cluster-allocated community trial.

BACKGROUND: Less than 2% of children in the U.S., ages 9-13, meet the minimum dietary recommendations for vegetable intake. The home setting provides potential opportunities to promote dietary behavior change among children, yet limited trials exist with child vegetable intake as a primary outcome. Strategies to increase vegetable intake grounded in behavioral economics are no/low cost and may be easily implemented in the home by parents. METHODS: This non-randomized, controlled study tested whether an intervention of parent-led strategies informed by behavioral economics and implemented within a series of 6 weekly parent-child vegetable cooking skills classes, improved dietary outcomes of a diverse sample of low-income children (ages 9-12) more than the vegetable cooking skills classes alone. The primary outcomes were total vegetable intake, dietary quality (HEI scores), total energy intake, vegetable liking, variety of vegetables tried, child BMI-z score, and home availability of vegetables. Outcome measures were collected at baseline, immediate post-treatment, 6 and 12 months follow-up. Mixed model regression analyses with fixed independent effects (treatment condition, time point and treatment condition x time interaction) were used to compare outcomes between treatment conditions. RESULTS: A total of 103 parent/child pairs (intervention = 49, control = 54) were enrolled and 91 (intervention = 44, control = 47) completed the weekly cooking skills program. The intervention did not improve child total vegetable intake. Intervention children increased dark green vegetable intake from immediate post-treatment to 12 months. The number of vegetables children tried increased and mean vegetable liking decreased over time for both control and intervention children. CONCLUSIONS: Findings from this study suggest that the strategies and the manner in which they were implemented may not be effective in low-income populations. The burden of implementing a number of strategies with potentially higher food costs may have constrained the ability of families in the current study to use the strategies as intended. TRIAL REGISTRATION: This trial has been retrospectively registered at : # NCT03641521 on August 21, 2018.

The Role of Adolescents From a Low Socioeconomic Background in Household Food Preparation: A Qualitative Study.

The purpose of this study was to understand adolescents' from low-income households perceptions of their involvement in home food preparation, reasons underlying the extent to which they were involved, and positive and negative consequences associated with their involvement. Semistructured interviews were conducted with a convenience sample of 19 adolescents (13-18 years). Audio-recorded interviews were transcribed verbatim. Themes were identified using grounded theory and the constant comparative method. Eight adolescents described cooking as a primary responsibility due to adult work and family schedules, age, gender, and/or cultural expectations. They were typically preparing food for themselves and their family without assistance, and making decisions about what was prepared. They identified positive and negative consequences including enjoyment and satisfaction, as well as stress and less time for other activities. Eleven adolescents mostly assisted the primary food preparer, with little input in deciding what was prepared. They identified benefits such as enjoyment and family interaction. Foods prepared by many adolescents tended to be quick and easy to prepare foods. Future studies should investigate the relationship between adultified cooking responsibilities, diet quality, and health. Also, cooking education for adolescents needs to address how to prepare a healthy family meal on a budget.

Examining the feasibility of implementing behavioural economics strategies that encourage home dinner vegetable intake among low-income children.

OBJECTIVE: To examine the feasibility of implementing nine behavioural economics-informed strategies, or 'nudges', that aimed to encourage home dinner vegetable intake among low-income children. DESIGN: Caregivers were assigned six of nine strategies and implemented one new strategy per week (i.e. 6 weeks) during three dinner meals. Caregivers recorded child dinner vegetable intake on the nights of strategy implementation and rated the level of difficulty for assigned strategies. Baseline data on home vegetable availability and child vegetable liking were collected to assess overall strategy feasibility. SETTING: Participants' homes in a large Midwestern metropolitan area, USA. SUBJECTS: Low-income caregiver/child (aged 9-12 years) dyads (n 39). RESULTS: Pairwise comparisons showed that child dinner vegetable intake for the strategy 'Serve at least two vegetables with dinner meals' was greater than intake for each of two other strategies: 'Pair vegetables with other foods the child likes' and 'Eat dinner together with an adult(s) modelling vegetable consumption'. Overall, caregivers' mean rating of difficulty for implementing strategies was 2·6 (1='not difficult', 10='very difficult'). Households had a mean of ten different types of vegetables available. Children reported a rating ≥5 for seventeen types of vegetable on a labelled hedonic scale (1='hate it', 5-6='it's okay', 10='like it a lot'). CONCLUSIONS: Behavioural economics-informed strategies are feasible to implement during dinner meals, with some strategies differing by how much they influence vegetable intake among low-income children in the home.

Satiation and satiety sensations produced by eating oatmeal vs. oranges. a comparison of different scales.

The primary objective of this study was to use the 5-Factor Satiety Questionnaire (Karalus, 2011) to compare the changes in satiation and satiety produced by eating oranges with the changes produced by eating oatmeal. A secondary objective was to compare the data from the 5-Factor Satiety Questionnaire with that from more traditionally used scales. Thirty participants evaluated hunger and fullness feelings before breakfast and at 0, 60, and 120 min after consuming breakfasts of equal volumes of oranges and oatmeal. We covertly recorded food intake from an ad libitum snack offered 2 h after breakfast. Oranges were less effective than oatmeal for decreasing mental hunger immediately after eating. Mental hunger increased more and mental fullness decreased more during the 2-h period after eating oranges than after eating oatmeal. Neither physical hunger changes nor physical fullness changes differed between the two foods. Participants ate more food at an ad libitum snack 2 h after eating the oranges compared with after eating the oatmeal. We were better able to distinguish the feelings produced by the oatmeal from the feelings produced by the oranges with the factor scales than with the traditional scales of hunger and fullness.

Increasing portion sizes of fruits and vegetables in an elementary school lunch program can increase fruit and vegetable consumption.

Increasing portion size can increase children's consumption of food. The goal of this study was to determine whether increasing the portion sizes of fruits and vegetables in an elementary school cafeteria environment would increase children's consumption of them. We measured each child's consumption of the fruit and vegetables served in a cafeteria line on a control day (normal cafeteria procedures) and on two intervention days. When we increased the portion size of 3 of the 4 fruits and vegetables by about 50%, children who took those foods increased their consumption of them. Although this was an effective strategy for increasing fruit and vegetable consumption among students who took those foods, many children chose not to take any fruits or vegetables. Further efforts are needed to increase children's selection and consumption of fruits and vegetables in an environment of competing foods of higher palatability.

Effect of plant-derived antimicrobials against multidrug-resistant Salmonella Heidelberg in ground Turkey.

Salmonella Heidelberg (SH) is a highly invasive human pathogen for which turkeys can serve as reservoir hosts. Colonization of turkeys with SH may result in potential contamination and is a greater challenge to prevent in comminuted products. Antimicrobial efficacy of 3 GRAS-status plant-derived antimicrobials (PDAs), lemongrass essential oil (LG), citral (CIT), and trans-cinnamaldehyde (TC), against SH in ground turkey, a comminuted product implicated in several outbreaks, was evaluated in this study. Ground turkey samples inoculated with ∼3.50 log10 CFU/g of a three-strain SH cocktail were treated with either LG, CIT, or TC at either 0.5, 1, or 2% (vol/wt). Samples were stored at 4°C, and bacterial enumeration was performed on d 0, 1, 3, and 5. Appropriate controls were included alongside all treatments. Fluorescence microscopy was performed to evaluate the direct impact of the PDAs against SH in vitro. Appearance and aroma difference testing of raw patties was also performed for select treatments with trained sensory panelists. Treatment with 2% TC yielded a 2.5 log10 CFU/g reduction by d 1 and complete reduction by d 5 (P < 0.05). By d 3, 2% CIT and 2% LG resulted in SH reduction of at least 1.7 log10 CFU/g (P < 0.05). Addition of 1% TC resulted in reduction of at least 1.8 log10 CFU/g by d 3 (P < 0.05). Participants could distinguish PDA-treated raw patties by aroma. Most participants (7/11) could not distinguish patties treated with 0.5% TC based on appearance. Microscopic images indicate that all PDAs resulted in disruption of the SH membrane. Results of the present study indicate that the three tested PDAs, LG, CIT, and TC are effective against SH in ground turkey, indicating their potential use as interventions to mitigate Salmonella contamination in comminuted turkey products.

The effect of intense pulsed light on the sensory properties of nonfat dry milk.

Our objectives were to examine (1) how intense pulsed light (IPL) processing parameters (exposure time and initial temperature) affected aroma, flavor, and mouthfeel of nonfat dry milk, (2) which levels of each parameter produced aroma, flavor, and mouthfeel changes from an untreated control sample, and (3) whether minimal or intense processing conditions produced a noticeable appearance change from the control. Four exposure times (1, 2, 3, and 4 passes through the IPL chamber) and three initial temperatures (25, 30, and 35℃) were studied with untreated milk powder as the control. The samples were prepared as both milk powder and reconstituted milk for sensory evaluation. Using standard evaluating protocols, trained descriptive analysis panelists rated the aroma, flavor, and mouthfeel of these samples. Panelists compared the appearance of the IPL-treated samples that underwent a minimal or intense processing condition to the control by using a two-out-of-five difference test. Increasing the exposure time led to increased intensities of overall flavor, burnt flavor, and umami taste in both milk powder and reconstituted milk, while increasing temperature increased animal and sulfur aromas in reconstituted milk only. Compared to the control, all levels of exposure time at any initial temperature resulted in increased aroma and flavor including cardboard aroma, sulfur aroma, and brothy flavor in both milk powder and reconstituted milk. Only the 4-pass exposure at the initial temperature of 25℃ changed the appearance of milk powder. However, the appearance change was not noticeable in reconstituted milk. PRACTICAL APPLICATION: The standard evaluation protocols and lexicons provide useful tools for research on milk powder. Additionally, the understanding of critical factors impacting sensory properties will contribute to a better implementation of this decontamination technology.

Liking of food textures and its relationship with oral physiological parameters and mouth-behavior groups.

Researchers have categorized people into four "mouth-behavior" groups based on their oral processing preferences, and claimed that members of those mouth-behavior groups differ in their food texture preferences. If people could be classified into groups based on their liking of different textures, food products could be targeted to specific subgroups, potentially enhancing consumer acceptability. In the first part of our study, we grouped people based on their liking ratings of a wide variety of food textures by asking 288 participants to rate their liking of 106 food texture attributes in an online survey. In the second part of our study, we further examined relationships among individuals' food texture liking ratings, mouth-behavior group membership, and measurements of four oral physiological parameters (saliva flow rate, chewing efficiency, biting force, and particle size sensitivity). One-hundred participants completed the online survey on food texture liking, classified themselves into one of four mouth-behavior groups (Chewers, Crunchers, Smooshers, and Suckers), and were measured for four oral physiological parameters. We refuted the idea that large texture-liking subgroups exist. Although our participants self-categorized themselves into the four mouth-behavior groups similarly to previous researchers, our texture liking measurements did not support the presumed preferences of those mouth-behavior groups. Clustering of participants on their oral physiological measurements produced a "low particle-size sensitivity" cluster, a "high biting force" cluster, a "high saliva flow rate" cluster, and a "low saliva flow and low chewing efficiency" cluster. Neither our texture liking nor our oral physiological measurements predicted membership in the four mouth-behavior groups.

Catalytic intense pulse light inactivation of Cronobacter sakazakii and other pathogens in non-fat dry milk and wheat flour.

The outbreaks of Cronobacter sakazakii, Salmonella spp, and Bacillus cereus in powdered foods have been increasing in worldwide. However, an effective method to pasteurize powdered foods before consumption remains lacking. A prototype Intense Pulsed Light (IPL) system was developed to disinfect powdered foods under different IPL and environmental conditions. Synergistic effect of IPL and TiO2 photocatalysis on microbial inactivation was studied. The results show that high energy intensity of each pulse, high peak intensity, and short pulsed duration contributed to a high microbe inactivation. With TiO2 photocatalysis, one additional log10 reduction was achieved, bringing the total log reduction to 4.71 ± 0.07 (C. sakazakii), 3.49 ± 0.01 (E. faecium), and 2.52 ± 0.10 (B. cereus) in non-fat dry milk, and 5.42 ± 0.10 (C. sakazakii), 4.95 ± 0.24 (E. faecium), 2.80 ± 0.23 (B. cereus) in wheat flour. IPL treatment combined with the TiO2 photocatalysis exhibits a strong potential to reduce the energy consumption in improving the safety of powdered foods.

Consumer views of hunger and fullness. A qualitative approach.

The objective of this study was to gain a better understanding of the complex ideas of hunger and fullness from consumers through the use of focus groups. We report results of 4 focus group interviews with (1) female normal weight dieters, (2) female normal weight non-dieters, (3) female overweight dieters and non-dieters, and (4) male normal weight dieters and non-dieters. Hunger and fullness sensations were described as having both physical and psychological components that were divided into two groups: typical and extreme. Overall, hunger was described as the presence of stomach growls, stomach hunger pains, emptiness, focus on eating, loss of energy, and desire to eat. Fullness was described as a feeling of food in the stomach, stomach stretch, satisfaction, contentment, energized, focused, and lack of the desire to eat. Typical fullness was described with many psychological components while typical hunger was primarily physical in nature. Participants described situations where sensations of mental hunger and physical fullness overlapped, which provided evidence that the overall constructs of hunger and fullness may not be simple, polar opposites.

Implementation of Parental Strategies to Improve Child Vegetable Intake: Barriers and Facilitators.

Purpose. To qualitatively assess barriers and facilitators to implementing specific behavioral strategies to increase child vegetable intake during home dinner meals by low-income parents. Method. Parents (n = 49) of children (9-12 years) were asked to implement 1 behavioral strategy following each of 6 weekly cooking classes at community centers. Example strategies included serving vegetables first, serving 2 vegetables, and using a bigger spoon to serve vegetables. The following week, parents discussed how they used the strategy and barriers and facilitators to its use. Discussions were recorded, transcribed verbatim, and coded separately by strategy using NVivo Pro 11 software. Inductive, comparative thematic analyses were used to identify themes by strategy. Results. Most participants were multiethnic women aged 30 to 39 years with low food security. Time and scheduling conflicts limited involvement of children in vegetable preparation (Child Help strategy). The type of foods served and an unfamiliar serving style inhibited use of the MyPlate and Available/Visible strategies, respectively. Children's dislike of vegetables limited use of the Serve Vegetables First and Serve 2 Vegetables strategies. Ease of use promoted use of the Bigger Spoon strategy. Conclusion. Educators could tailor application of specific parent strategies for low-income families based on child and environmental characteristics.

Evaluation of Methods for Inoculating Dry Powder Foods with Salmonella enterica, Enterococcus faecium, or Cronobacter sakazakii.

Salmonella and Cronobacter are two bacteria of concern in powdered food ingredients with low water activity, due to their ability to remain viable for long periods of time. There is great interest in studying the survival of these bacteria in powdered foods, but discrepancies have been reported between broth-grown and lawn-grown bacterial cells and their thermal resistance and desiccation tolerance once inoculated onto powdered foods. The purpose of this study was to evaluate three different powdered food inoculation methods, two broth-grown and one lawn-grown. To evaluate these methods on three types of powdered food matrices, Salmonella enterica serovar Typhimurium LT2 (ATCC 700720), Salmonella surrogate Enterococcus faecium (NRRL B-2354), and Cronobacter sakazakii (ATCC 29544) were inoculated onto nonfat dry milk powder, organic soy flour, and all-purpose flour using one of the three previously developed inoculation methods. In the first broth-grown method, labeled broth-grown pelletized inoculation, a bacterial cell pellet was added to powdered foods directly and mixed with a sterile wooden stick. The second broth-grown method, labeled broth-grown spray inoculation, used a chromatography reagent sprayer to spray the bacterial cell suspension onto the powdered foods. The third inoculation method, lawn-grown liquid inoculation, made use of a spot inoculation and a stomacher to incorporate each bacterium into the powdered foods. Results indicated that the method of inoculation of each powder impacted repeatability and bacteria survivability postequilibration (4 to 6 days). Broth-grown spray inoculation, regardless of the powder and bacterium, resulted in the highest log reduction, with an average ∼1-log CFU/g reduction following equilibration. Broth-grown pelletized inoculation resulted in the second-highest log reduction (∼0.79 log CFU/g), and finally, lawn-grown liquid inoculation was the most stable inoculation method of the three, with ∼0.52-log CFU/g reduction. Overall, the results from this inoculation study demonstrate that inoculation methodologies impact the desiccation tolerance and homogeneity of C. sakazakii, E. faecium, and Salmonella Typhimurium LT2.

The use of a combination of instrumental methods to assess change in sensory crispness during storage of a "Honeycrisp" apple breeding family.

Loss of crispness in apple fruit during storage reduces the fruit's fresh sensation and consumer acceptance. Apple varieties that maintain crispness thus have higher potential for longer-term consumer appeal. To efficiently phenotype crispness, several instrumental methods have been tested, but variable results were obtained when different apple varieties were assayed. To extend these studies, we assessed the extent to which instrumental measurements correlate to and predict sensory crispness, with a focus on crispness maintenance. We used an apple breeding family derived from a cross between "Honeycrisp" and "MN1764," which segregates for crispness maintenance. Three types of instrumental measurements (puncture, snapping, and mechanical-acoustic tests) and sensory evaluation were performed on fruit at harvest and after 8 weeks of cold storage. Overall, 20 genotypes from the family and the 2 parents were characterized by 19 force and acoustic measures. In general, crispness was more related to force than to acoustic measures. Force linear distance and maximum force as measured by the mechanical-acoustic test were best correlated with sensory crispness and change in crispness, respectively. The correlations varied by apple genotype. The best multiple linear regression model to predict change in sensory crispness between harvest and storage of fruit of this breeding family incorporated both force and acoustic measures. PRACTICAL APPLICATIONS: This work compared the abilities of instrumental tests to predict sensory crispness maintenance of apple fruit. The use of an instrumental method that is highly correlated to sensory crispness evaluation can enhance the efficiency and reduce the cost of measuring crispness for breeding purposes. This study showed that sensory crispness and change in crispness after storage of an apple breeding family were reliably predicted with a combination of instrumental measurements and multiple variable analyses. The strategy potentially can be applied to other apple varieties for more accurate interpretation of crispness maintenance measured instrumentally.

Children Residing in Low-Income Households Like a Variety of Vegetables.

Child vegetable intake falls far below the minimum recommended levels. Knowing which vegetables children may like help those responsible for providing vegetables to children to improve intake. The objective of this study was to measure vegetable liking for a wide variety of vegetables by a racially and ethnically diverse population of 9⁻12-year old children from low-income families. Children rated their liking of 35 vegetables using a 10-point hedonic scale. We tabulated the number of children that found each vegetable acceptable (ratings of 'okay' or above) and the number that found each vegetable unacceptable (ratings below 'okay'). More than 50% of children who had tried a vegetable considered it acceptable. A large majority of the vegetables had mean ratings in the acceptable range. Corn was the most liked vegetable, closely followed by potatoes, lettuce, and carrots. Artichoke had the lowest mean liking, followed by onion and beets. We found children liked a wide variety of vegetables which offers counter evidence to the commonly held perception that children do not like vegetables.

Impacts of a Vegetable Cooking Skills Program Among Low-Income Parents and Children.

OBJECTIVE: To evaluate the impact of a vegetable-focused cooking skills and nutrition program on parent and child psychosocial measures, vegetable liking, variety, and home availability. DESIGN: Baseline and postcourse surveys collected 1-week after the course. SETTING: Low-income communities in Minneapolis-St Paul. PARTICIPANTS: Parent-child dyads (n = 89; one third each Hispanic, African American, and white) with complete pre-post course data; flyer and e-mail recruitment. INTERVENTION(S): Six 2-hour-weekly sessions including demonstration, food preparation, nutrition education lessons, and a meal. MAIN OUTCOME MEASURES: Parental cooking confidence and barriers, food preparation/resource management, child self-efficacy and cooking attitudes, vegetable liking, vegetable variety, and vegetable home availability. ANALYSIS: Pre-post changes analyzed with paired t test or Wilcoxon signed-rank tests. Results were significant at P < .05. RESULTS: Increased parental cooking confidence (4.0 to 4.4/5.0), healthy food preparation (3.6 to 3.9/5.0), child self-efficacy (14.8 to 12.4; lower score = greater self-efficacy), vegetable variety (30 to 32/37 for parent, 22 to 24/37 for child), and home vegetable availability (16 to 18/35) (all P < .05). CONCLUSIONS AND IMPLICATIONS: A short-term evaluation of a vegetable-focused cooking and nutrition program for parents and children showed improvements in psychosocial factors, variety, and home availability.

Perceptions of children, parents, and teachers regarding whole-grain foods, and implications for a school-based intervention.

OBJECTIVE: To identify perceptions of whole-grain foods and factors influencing intake by children, parents, and teachers as the basis for increasing intake by children within a school-based intervention. DESIGN: Focus group interviews with questions based on Social Cognitive Theory. SETTING: After-school care programs in 4 elementary schools in a large metropolitan district in St. Paul, Minn. PARTICIPANTS: Seven, three and two focus group interviews with children (n = 40; grades K-6), parents (n = 18), and teachers (n = 11), respectively. PHENOMENON OF INTEREST: Child and adult factors influencing intake of whole-grain foods, with a tasting activity to stimulate discussion. ANALYSIS: Qualitative data analysis procedures to generate common themes from encoded transcripts. RESULTS: Adults and children were positive about sensory characteristics of whole-grain products. Knowledge of ways to identify these foods was limited. Taste preferences strongly influenced selection of bread and cereals. Children suggested that new school foods should look and taste good, be familiar, and be promoted through sampling, peer influence, and incentives. Adults suggested a gradual increase in whole-grain content of school meals. IMPLICATIONS FOR RESEARCH AND PRACTICE: Focus groups were useful in understanding perceptions regarding whole-grain foods and yielded valuable insight toward design of a school-based intervention.

Serving first in isolation increases vegetable intake among elementary schoolchildren.

Many people want to eat healthier, but they often fail in these attempts. We report two field studies in an elementary school cafeteria that each demonstrate children eat more of a vegetable (carrots, broccoli) when we provide it first in isolation versus alongside other more preferred foods. We propose this healthy first approach succeeds by triggering one's inherent motivation to eat a single food placed in front of them, and works even though they have prior knowledge of the full menu available and no real time constraints. Consistent with this theory, and counter to simple contrast effects, an additional lab study found that presenting a food first in isolation had the unique ability to increase intake whether the food was healthy (carrots) or less healthy (M&M's). Our findings demonstrate the effectiveness of this simple intervention in promoting healthier eating, which should interest consumers, food marketers, health professionals, and policy makers.

Testing the effectiveness of in-home behavioral economics strategies to increase vegetable intake, liking, and variety among children residing in households that receive food assistance.

OBJECTIVE: To test the effectiveness of behavioral economics strategies for increasing vegetable intake, variety, and liking among children residing in homes receiving food assistance. DESIGN: A randomized controlled trial with data collected at baseline, once weekly for 6 weeks, and at study conclusion. SETTING: Family homes. PARTICIPANTS: Families with a child (9-12 years) will be recruited through community organizations and randomly assigned to an intervention (n = 36) or control (n = 10) group. INTERVENTION: The intervention group will incorporate a new behavioral economics strategy during home dinner meal occasions each week for 6 weeks. Strategies are simple and low-cost. MAIN OUTCOME MEASURE(S): The primary dependent variable will be child's dinner meal vegetable consumption based on weekly reports by caregivers. Fixed independent variables will include the strategy and week of strategy implementation. Secondary dependent variables will include vegetable liking and variety of vegetables consumed based on data collected at baseline and study conclusion. ANALYSIS: Mean vegetable intake for each strategy across families will be compared using a mixed-model analysis of variance with a random effect for child. In additionally, overall mean changes in vegetable consumption, variety, and liking will be compared between intervention and control groups.
