Trying versus liking fruits and vegetables: correspondence between mothers and preschoolers

Extensive research indicates that a diet rich in fruits and vegetables (F&V) protects against numerous illnesses in adulthood, but that most individuals, including children, consume far fewer F&V per day than is recommended. Since evidence suggests that eating habits in childhood track into adulthood, more research is necessary to learn about how parental F&V intake and opportunities influence child F&V consumption. The purpose of this study was to examine the relationship between mothers' F&V preferences and those of their preschool-age children to determine if greater maternal "liking" of fruits and vegetables was associated with their reports of their children's "trying" more fruits and vegetables. Eighty-three mothers completed a questionnaire that assessed whether they and their preschoolers had tried or liked a variety of F&V. Mothers liked 86% of the fruits they tried, girls 76%, and boys 69%. Mothers liked 81% of the vegetables they tried; boys and girls liked 55%. Mothers' likes correlated with F&V that their children tried, but mothers' likes also limited the number of F&V that their children tried. Mothers reported preferences for F&V are associated with estimates of their preschoolers' preferences for F&V. Relative to girls, boys may need additional opportunities for F&V exposure.     

Explaining school children's fruit and vegetable consumption: the contributions of availability, accessibility, exposure, parental consumption and habit in addition to psychosocial factors

We studied the contributions of parental fruit and vegetable (F&V) consumption, availability and accessibility of F&V in the home, exposure to F&V, and habit, in addition to psychosocial factors, in explaining F&V consumption in 4-12-year-old children. Furthermore, we looked for effect modification by ethnicity and gender. Children's parents (n = 1739) completed a questionnaire assessing psychosocial and additional factors regarding their children's F&V consumption. Consumption was assessed by a food-frequency questionnaire. The model explained the children's F&V consumption better when the additional factors were included (R2 = .49 and R2 = .50 for fruit consumption, and R2 = .33 and R2 = .33 for vegetable consumption). Stepwise multi-level regression analyses revealed that habit was the most influential correlate of F&V consumption. It is concluded that nutrition education interventions aimed at stimulating F&V consumption among children should take into account that the consumption of fruit and that of vegetables are clearly different behaviors, with different influencing factors for boys and girls and children of native or non-native background. Furthermore, interventions to increase F&V consumption should include strategies aimed at making these behaviors habitual.     

Impact of Personal Preference and Motivation on Fruit and Vegetable Consumption of WIC-Participating Mothers and Children in Atlanta,GA

ObjectiveTo determine the effect of psychosocial and sociodemographic factors on consumption of fruits and vegetables (F&V) for women and children participating in the Atlanta Special Supplemental Nutrition Program for Women, Infants, and Children.MethodsParticipants (n = 249) were selected from 2 Atlanta Special Supplemental Nutrition Program for Women, Infants, and Children agencies. Data from this analysis were collected from in-person interviews. The dichotomous dependent variable was whether participants met recommended intakes for F&V. Independent variables were personal preference and motivation factors of F&V consumption, and sociodemographic factors. Bivariate analysis determined significant factors to include in logistic models.ResultsOnly 27.7% of mothers and 44.2% of their oldest child consumed > 5 servings of F&V daily. Not knowing how to prepare F&Vs and spoilage of F&V before eating them were significantly related to F&V consumption of mothers.Conclusions and ImplicationsFood storage and preparation resulted in significant differences in meeting criteria for F&V consumption. Future initiatives should include cooking classes and emphasize food preparation techniques.     

Portion size selection of fruits and vegetables by 9- to 10-year-old children in Liverpool

BACKGROUND: It is important to promote the intake of fruit and vegetables but it is not clear how children interpret the term 'portion'. The aim of this study was to describe portion sizes of various fruits and vegetables selected by primary school children. METHODS: A cross-sectional study collected data on children's self-selected portions of fruits and vegetables. Forty-three boys and 52 girls aged 9-10 years attending after school food clubs in Liverpool took part. Children placed a 'portion' of each fruit and vegetable into an empty bowl which was weighed using digital scales accurate to 1 g. RESULTS: Mean portion sizes ranged from 126 g for satsumas to 61 g for peas but there were no significant differences between boys and girls. Portions of fruits were larger than portions of vegetables and although there were statistically significant correlations between the portion sizes selected by individual children they were not particularly strong. CONCLUSIONS: These children had all taken part in activities promoting '5-a-day' but their perception of 'a portion' varied enormously. It is recommended that children receive targeted activities to help them improve their understanding of what constitutes a 'portion'.     

The relationship of weight-related perceptions, goals, and behaviors with fruit and vegetable consumption in young adolescents

BACKGROUND: The effect of dieting and weight-control perceptions, goals, and behaviors on food intake, including fruit and vegetable (F&V) consumption, is not completely understood. We examined these associations in 1,755 young adolescents. METHODS: Data from the Teens Eating for Energy and Nutrition at School (TEENS) study were analyzed separately by gender using mixed linear modeling. Surveys completed at the beginning and end of 7th grade asked students to self-report fruit and vegetable consumption, weight-related perceptions, goals, and behaviors, and demographic variables. RESULTS: Underweight boys reported 0.8 fewer F&V servings per day than boys who reported their weight to be 'about right' (P = 0.002), while overweight girls reported 0.7 fewer F&V than girls who reported their weight to be 'about right' (P = 0.005). Boys with weight-related goals consumed significantly more F&V than did boys not wanting to do anything about their weight (P < 0.05). Girls engaging in weight-related behaviors reported 0.7 more F&V than girls who did not engage in weight-related behaviors (P = 0.006). CONCLUSIONS: Because F&V intake is low among all adolescents, population interventions should take place to increase F&V intake. These data support the inclusion of gender-specific intervention components related to weight-related perceptions, goals, and behaviors.     

Increasing fruit and vegetable consumption among 4th and 5th grade students: results from focus groups using reciprocal determinism

The Year 2000 Goals for the U.S. identify a goal of five servings per day of fruits and vegetables (F&V), which is roughly double what children are currently eating. Focus group discussions (based on the reciprocal determinism concept in social learning theory) were conducted with 4th and 5th grade students, their parents, teachers, and school food service workers, in preparation for the design of a school nutrition education program to increase consumption of F&V. A social learning theory perspective was taken because it has been demonstrated to be useful in the design of effective school nutrition education programs. A theory-based protocol delineating the sequence of questions to be asked in each focus group was designed before each group met. Discussions were conducted with ten groups of students, two groups each of teachers and of parents, and one of school food service employees. Three general factors appeared to be most likely to increase F&V consumption in these children: increasing availability of F&V in the home, enhancing liking for vegetables, and providing skills in increasing F&V availability and in preparing F&V.     

Children and eating. Personality and gender are associated with obesogenic food consumption and overweight in 6- to 12-year-olds

The role of children's personality traits in the consumption of potentially obesogenic foods was investigated in a sample of Norwegian children aged 6-12 years (N=327, 170 boys, 157 girls). Mothers rated their child's personality on the traits of the Five Factor Model (i.e., extraversion, benevolence, conscientiousness, neuroticism, and imagination). Mothers also completed a food frequency questionnaire assessing their child's consumption of sweet drinks, sweet foods, and fruit and vegetables, and reported their child's height and weight. Controlling for age and mothers' education, boys and girls who were less benevolent consumed more sweet drinks, and girls who were less conscientious and more neurotic consumed more sweet drinks. Boys and girls who were more benevolent and imaginative consumed more fruits and vegetables, and boys who were more extraverted, more conscientious, and less neurotic consumed more fruits and vegetables. Controlling for maternal education, boys and girls who were less extraverted, and girls who were less benevolent, less conscientious, and more neurotic were more likely to be overweight or obese. These findings suggest that children's personality traits play an important yet understudied role in their diet. Further investigation of mechanisms that relate child traits to obesogenic eating and overweight would be valuable.     

Lebensmittelverzehr bei Kindern und Jugendlichen in Deutschland

Since dietary behaviour has an essential impact on health, information on food consumption was obtained in the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). The average food frequency and portion size "in recent weeks" was assessed with a food frequency questionnaire. Two versions of the questionnaire, identical in content, exist: one aimed at parents of 1-10-year-olds and the other directly at 11-17-year-olds. The results include data on 7,186 boys and 6,919 girls, aged 3-17. About half of the participants each consume bread, milk and fresh fruits every day. The majority (about three quarter) eat fast food only once a month or less. However, 16 % of the participants eat chocolate, and almost 20 % other sweets every day. More boys than girls individually consume soft drinks, milk, dairy products, meat, sausage, cereals and white bread every day. More girls consume fresh fruits and raw vegetables each day. With increasing age the proportion of daily consumers of soft drinks, cheese (and among boys also meat and sausage) increases, but the proportion of daily consumers of juices, tap water, milk, dairy products, fresh fruits, raw vegetables, cookies, chocolate, sweets (and among girls also breakfast cereals) falls. As expected the consumption of sweets and soft drinks is relatively high. Whereas more than half of the children each consume fruits and vegetables on a daily base, this consumption declines with increasing age.     

Environmental and personal correlates of fruit and vegetable consumption in low income, urban Mexican children.

BACKGROUND: Epidemiological evidence suggests that populations with high fruit and vegetable (FV) consumption have a lower risk for childhood obesity, cancer and cardiovascular diseases. There are no studies that address the correlates of FV intake in Mexican children; therefore, the aim of this study was to identify the frequency of FV consumption by children in Mexico City's low income state schools and their personal (preferences, expectancy, knowledge and self-efficacy) and environmental (accessibility and person in charge of cooking at home) correlates. METHODS: A validated questionnaire to assess accessibility, expectancy, self-efficacy, preference and knowledge; and a 2-day dietary recall were used to assess the FV intake and its correlates in 327 children. Statistical analysis included chi-square and stepwise logistic regression. RESULTS: Average consumption of FV was once a day with a higher proportion of girls consuming FV 3 or more times per day (15.2% versus 6.7%; P < 0.01). The environmental factors that influenced a higher consumption of FV were the mother being responsible for cooking at home (P < 0.02) and accessibility to FV (P < 0.01); whereas the personal factors were self-efficacy (P < 0.05) and preference (P < 0.03) to vegetables. CONCLUSION: Correlates of fruit and vegetable consumption in children from Mexico City's State Schools were being female and accessibility to fruits and vegetables. Home and school environments are decisive for the children to increase FV consumption. Creative ways to encourage FV consumption in boys should be explored. These factors should be considered when designing programmes aimed at increasing consumption of fruits and vegetables in children.     

Barriers to compliance with the Daily Food Guide for Children among first-grade pupils in a rural area in the Philippine Island of Mindanao

BACKGROUND/OBJECTIVE: To identify and address caregivers' perceived barriers to compliance with dietary guidelines for children. SUBJECTS/METHODS: Information on family socioeconomic status, child's consumption frequency of nine food items, and caregiver's attitudes and behaviors regarding meal preparation were collected through structured interviews with caregivers (70 mothers, four grandmothers and one father) of first-grade children (39 boys and 36 girls) living in five barangays of New Corella, Mindanao Island, Philippines. If the child's intake did not reach the level recommended in the dietary guidelines, the reasons were investigated from the economic, social, cultural and environmental viewpoints. RESULTS: Their diet relied heavily on rice and others. The percentages of children who did not consume each of the food items on a daily basis were 77.3% for eggs; 57.3% for milk; 41.3% for fish/meat/poultry/dried beans/nuts (FMPDBN); 42.7% for fruits; 17.4% for green, leafy and yellow (GLY) vegetables; and 38.5% for other vegetables. The most reported reasons for the infrequent consumption of FMPDBN (87.1%), milk (81.4%) and eggs (36.2%) were 'no money to buy,' that of fruits (59.4%) was 'out of season' and that of GLY (61.5%) and other vegetables (55.2%) was 'child's dislike.' CONCLUSIONS: The expansion of homestead food production and the national feeding program contribute to increased animal food consumption. Nutrition education aimed at overcoming food preferences and increasing the awareness of micronutrient intake are perhaps the most effective means to promote vegetable intake.     

Longitudinal trends in consumption of vegetables and fruit in Finnish children in an atherosclerosis prevention study (STRIP)

OBJECTIVE: To assess prospectively the consumption of fruit and vegetables and its' correlation to the parental consumption in boys and girls taking part in an atherosclerosis prevention study (Special Turku Coronary Risk Factor Intervention Project for Children (STRIP) study). HYPOTHESIS: Nutrition counselling focused on cardiovascular health effects vegetable and fruit consumption. DESIGN: A prospective, randomised, clinical trial. SUBJECTS: Children were recruited to the STRIP study between 1989 and 1992. At the age of 7 months, children were randomised to the intervention (n = 540) or the control group (n = 522) and were followed up until the age of 11 years. INTERVENTION: Families in the intervention group have, since randomisation, received biannual individualised dietary counselling aimed at reduction of cardiovascular risk factors, especially saturated fat intake. Food records were used to assess fruit and vegetable consumption of children and parents. RESULTS: The percentage of total energy intake provided by fruit and vegetables decreased when the children grew older (P for age <0.001). The 1- to 10-year-old intervention boys consumed more vegetables (mean difference 3.18 g/day; CI 1.48-4.86; P < 0.001) and fruit (mean difference 10.1 g/day; CI 5.28-14.94; P < 0.001) than did the control. Mother's consumption correlated with the consumption of their daughters and sons, whereas father's consumption correlated only with the consumption of their sons. CONCLUSIONS: Finnish children taking part in the atherosclerosis prevention study had a remarkably low fruit and vegetable consumption, which furthermore decreased with age. The children's consumption correlated with the parental consumption, except between boys and mothers. A slight intervention effect was present only among boys.     

A measure of outcome expectations for fruit and vegetable consumption among fourth and fifth grade children: reliability and validity

An outcome expectations questionnaire for fruit and vegetable(F&V) consumption among fourth and fifth grade studentswas developed, pilot-tested at one school and field-tested attwo schools. Seventeen questions generated from focus groupswere listed for fruits and repeated for vegetables. Principalcomponents analysis indicated two subscales ‘social’and ‘health and physical ability’ accounting for37.3% of the total variance; items loaded on the same subscaleswhen applied to fruits or vegetables. Internal consistenciesand test-retest reliabilities for the subscales were acceptable.Mean scores for the ‘health and physical ability’subscale were almost twice as large as the ‘social’subscale regardless of gender, grade and ethnicity. Pearsoncorrelations between F&V outcome expectation subscales andconsumption of F&V (from daily food records) were low, similarto patterns of correlations with preferences for F&V. Furtherresearch regarding outcome expectations is needed to clarifythe extent of their impact on F&V consumption specifically,and perhaps on consumption in general, among pre-adolescentchildren.     

Association of physical activity and dietary behaviours in relation to the body mass index in a national sample of Iranian children and adolescents: CASPIAN Study

OBJECTIVE: To examine the relation of dietary and physical activity (PA) patterns with the body mass index (BMI), and the associations between these patterns among children. METHODS: A representative sample of 21 111 school students aged 6-18 years was selected by multistage random cluster sampling from 23 provinces in the Islamic Republic of Iran. PA and dietary pattern were assessed by self-administered validated questionnaires. FINDINGS: Fruit and vegetables, dairy products and snacks (salty, fatty or sweet) had a similar consumption frequency of approximately twice a day. The type of fat most frequently consumed was hydrogenated solid fat (consumed by 73.8% of families). The PA level was significantly higher among boys than girls, in rural than in urban residents, and in intermediate students than high-school students. Among boys, the frequency of consumption of vegetables and plant proteins (R(2) = 0.46); and among girls, the frequency of consumption of dairy products and fruits, as well as high PA level had a significant inverse association with BMI (R(2) = 0.57). Among boys, the low frequency of consumption of fruits, the time spent on PA and the energy expenditure; and among girls, the time spent on PA and the energy expenditure, had significant relationships with overweight. When controlling for covariates, PA levels had significant relationships with the frequency of consumption of all food groups. CONCLUSION: Unhealthy lifestyles make Iranian young people prone to chronic diseases later in life. When examining their health benefits, the interrelationship of dietary and PA behaviours should be considered.     

Associations between Parenting Styles and Children’s Fruit and Vegetable Intake

This study investigated associations between children’s fruit and vegetable intake and their parents’ parenting style (i.e., authoritative: high warmth-high control; authoritarian: low warmth-high control; permissive: high warmth-low control; and disengaged: low warmth-low control). Data from the Longitudinal Study of Australian Children K cohort, comprising approximately 5,000 children, were used for analyses in wave 1 (4–5 years), wave 2 (6–7 years), and wave 3 (8–9 years). Fruit and vegetable intake patterns were extracted through exploratory factor analysis. Boys with authoritarian mothers were found less likely to consume fruits and vegetables at 6–9 years. Children of both genders with authoritative and permissive fathers, and girls with authoritative mothers at 4–5 years were found most likely to consume fruits and vegetables two and four years later. Exploring possible mechanisms underlying such associations may lead to interventions aimed at increasing children’s consumption of fruits and vegetables.     

Introduction of farm stands in low-income communities increases fruit and vegetable among community residents

The purpose of this longitudinal pilot study was to measure the impact of introducing farm stands in low-income communities with limited access to fresh and quality fruits and vegetables (F&V) on residents' F&V consumption. Two farm stands were placed outside two local community sites one day a week for 12 weeks. A variety of locally grown, culturally appropriate produce was sold at the stands. Data on F&V intake, awareness and usage of farmers' markets, family behaviors, and importance of eating F&V were collected from individuals (n=61) before and after farm stands were placed in the two communities. Paired sample t-tests, chi-square and McNemar tests were used to evaluate the impact of the intervention on the outcome variables. Significance level was set at p<.05. Significant increases were found for participants' consumption of fruit, fruit juice, tomatoes, green salad, and other vegetables (P<.05). Additionally, participants also reported increases in mediating variables of F&V consumption. This study underscores the potential of farmers' markets to increase F&V consumption through increasing F&V access in low-income communities.     

Kinder sollten mehr Obst und Gemüse essen

A diet rich in fruits and vegetables in schoolchildren is important for the physical and cognitive development of the child as well as for the prevention of nutrition-related diseases. In Germany, 816?schoolchildren (boys and girls, aged 10-13?years) from 14?public schools in the central region of Hesse were asked about their fruit and vegetable intake in May?2009. The results show that the mean fruit intake is 185?g fruit per day and 83?g vegetables per day in all schoolchildren. There is no significant difference in the amounts of fruit consumed by boys and girls. Regarding the amounts of consumed vegetables, there is a significant difference between gender (p?=?0.004). Schoolchildren eat fruits more frequently than vegetables. Furthermore, they prefer sweet fruits and convenient vegetables. German schoolchildren still do not reach national recommendations for fruit and vegetable intake, although current results show slightly equal or rather lower intake levels for fruits, but not for vegetables, in comparison to other national studies (e.g., National Consumption Study II, Donald Study, and EsKiMo Study). Health-promotion strategies should focus on both fruit and vegetable consumption to ensure a large variety of food choices and nutrient intake.     

Serving larger portions of fruits and vegetables together at dinner promotes intake of both foods among young children

Serving larger portions of energy-dense foods has been shown to promote children's energy intake at meals. Whether larger portions increase children's intake of both fruits and vegetables (F&V) is less clear. A 2×2 within-subjects design systematically varied portion sizes of fruit (75 vs 150 g) and vegetable (75 vs 150 g) side dishes served at dinner. Children's F&V liking was measured using a validated tasting method. Thirty children aged 4 to 6 years were tested in a laboratory setting at 5:00 pm on weekdays from November 2008 through March 2009. Mixed linear models were used to determine effects of fruit portion size, vegetable portion size, and their interaction on food and energy intakes. Data are presented as model-based means±standard error unless otherwise indicated. When portions were doubled, children increased their vegetable intake by 37% (12±4 g; P<0.01) and their fruit intake by 70% (41±6 g; P<0.01). Vegetable portion size effects were not influenced by offering more fruit and vice versa. Portion size effects were limited to children who liked that particular food. Total meal energy intake did not vary by portion size condition. These results indicate that serving larger F&V portions at meals can be used to promote young children's intake of both foods without influencing total meal energy intake. Effects were not seen in children who disliked F&V, suggesting a need to combine increased F&V portions with strategies to increase their acceptance.     

Intakes of vitamin C, vegetables and fruits: which schoolchildren are at risk?

OBJECTIVE: The purpose of this study was to determine vitamin C intakes among American schoolchildren. We investigated the leading sources of vitamin C in children's diets, the leading vegetables and fruits consumed by children and differences in dietary intake associated with vitamin C consumption. METHODS: Data from 1,350 7- to 12-year-old and 908 13- to 18-year-old schoolchildren were obtained from the 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII). The children were stratified by age and gender and then split into three vitamin C consumption groups based upon two 24-hour recalls: low (0 to 30.0 mg), marginal (30.1 to 59.9 mg), and desirable (>60.0 mg). Data were analyzed by tabulation and by ANOVA followed by post hoc Scheffe's test. Outcome measures included food groups and energy-adjusted intakes of micro- and macronutrients. RESULTS: Among the 7- to 12-year-olds, 12% of boys and 13% of girls had mean vitamin C intakes that were less than 30 mg/day, and, among 13- to 18-year-olds, 14% of boys and 20% of girls had low vitamin C intakes. In addition to consuming significantly more vitamin C, children with desirable vitamin C intakes also consumed significantly more (p <0.001) energy-adjusted folate and vitamin B6; children with low vitamin C intakes tended to have significantly greater (p <0.001) energy-adjusted intakes of fat and saturated fat. Children with desirable vitamin C intakes consumed significantly more (p <0.006) high-vitamin C fruit juice, low-vitamin C vegetables and whole milk. Children with low vitamin C intakes on average consumed two daily servings of vegetables and fruits, of which less than 1/5 of a serving was citrus, while children with desirable vitamin C intakes consumed an average of one daily serving of citrus. CONCLUSIONS: A considerable number of children drastically under-consumed vitamin C and total vegetables and fruits. Overall, children with desirable vitamin C intakes had healthier diets, including more milk and vegetables, than did their peers with low vitamin C intakes. Health care professionals should continue to promote at least five daily servings of vegetables and fruits and should advise parents that at least one of these should be rich in vitamin C.     

Cross-sectional survey on the nutritional and life-style habits of secondary school students in Hungary

INTRODUCTION: The national representative survey of secondary school students (age: 15-18 years) was undertaken between 1997 and 2000. The authors presented the data related to the nutritional and life-style habits. METHODS: The data for 6,347 students (48.4% boys and 51.6% girls) were evaluated. The anonymous questionnaire contained inquiries on nutritional rhythm, food frequency, use of vitamin and mineral supplements, smoking, alcohol and drug consumption habits, regular physical activity and family background (qualification, smoking, alcohol consumption). Within the frame of personal interviews the authors collected data on students' history with regard to occurrence of diabetes mellitus, other chronic diseases and in girls the time of the first menstruation. Concerning parents' history the authors collected information on the incidence of hypertension, myocardial infarction, diabetes mellitus, and stroke. STATISTICAL EVALUATION: Data were recorded in Data-Ease database system, in forms of individual records. The individual records were converted to be suitable for the statistical evaluation by SPSS for windows 9 statistical program pack. Data are presented as means and percent distribution. RESULTS: The nutritional rhythm of students was irregular. The daily consumption of milk, dairy products, fruits, fresh vegetables and vegetable dishes was insufficient. Eighty percent of students added extra salt to foods. More than 49% of students regularly consumed some forms of vitamin and/or mineral supplements. Thirty five percent of boys and 30% of girls smoked daily, 14.6% of boys and 5.9% of girls consumed alcohol at least once a week. Fifteen percent of boys and 11% of girls already tried taking drugs at least once. Only 50% of boys and 31% of girls were involved in a regular physical activity. Twenty two percent of fathers and 25% of mothers had university qualifications, whereas intermediate qualifications were recorded in 63 and 59%, lower qualifications occurred in 8 and 13% of parents, respectively. The incidence of smoking was 42% for fathers and 36% for mothers. Weekly alcohol consumption was recorded in 11%, daily consumption in 7% among fathers, the same figures for mothers were 4-4%, respectively. The incidence of hypertension, myocardial infarction, diabetes mellitus, and stroke was 26; 3.4; 5.4 and 1.5% in fathers and 32.9; 4.2; 6.6 and 1.5% in mothers. CONCLUSIONS: The data collected in the complex nutritional hygienic survey revealed serious deficiencies in the nutritional and life style habits of secondary school students. These factors considerably contribute to the unfavorable statistics of nutrition related non-infectious diseases in adulthood.     

"Kids Choice" school lunch program increases children's fruit and vegetable acceptance

The "Kids Choice" school lunch program used token reinforcement, food choice, and peer participation to increase children's fruit and vegetable consumption without later drops in food preference sometimes found in past research and often called 'overjustification effects.' Participants included 188 school children (92 boys, 96 girls; mean age = 8.0; 95% Caucasian). After four baseline meals, children were randomly assigned for 12 meals to receive token reinforcement for eating either fruits or vegetables. Observers recorded fruit and vegetable consumption and provided token reinforcement by punching holes into nametags each day children ate their assigned foods, then once a week children could trade these tokens for small prizes. Fruit and vegetable preference ratings were gathered with child interviews during baseline, and during follow-up conditions two weeks and seven months after the token reinforcement program. Consumption increased for fruit and for vegetables and the increases lasted throughout reinforcement conditions. Two weeks after the program, preference ratings showed increases for fruit and for vegetables. Seven months later, fruit and vegetable preferences had returned to baseline levels, suggesting the need for an ongoing school lunch program to keep preferences high, but also showing no signs of "overjustification effects" from the token reinforcement used in the "Kids Choice" school lunch program.
