A 9-month family-based program in rural Minnesota significantly increased the vegetables families kept at home and improved the quality of foods served at dinner, according to Gram Research analysis of this randomized controlled trial. Children in the intervention group ate about 1/3 cup more fruit daily than control children, though this difference was not quite statistically significant. The study shows that teaching families to create healthier home food environments can produce meaningful changes, though additional strategies may be needed to increase physical activity and family meal frequency.
A new study tested whether teaching families to create healthier home environments could help prevent childhood obesity in rural areas. Researchers worked with 114 families with children ages 7-10 over 9 months, teaching them how to stock their kitchens with vegetables, serve better quality meals, and eat together as a family. According to Gram Research analysis, the program successfully increased the amount of vegetables families kept at home and improved the quality of foods served at dinner. While the results were modest, they show that focusing on what’s available in the kitchen and how families eat together can make a real difference in children’s eating habits.
Key Statistics
A 2026 randomized controlled trial of 114 rural children found that families receiving the NU-HOME intervention significantly increased vegetable availability in their homes and improved the quality of foods served at evening meals compared to control families.
In the NU-HOME study published in 2026, children whose families received the intervention consumed approximately 1/3 cup more fruit per day than children in the control group, representing a clinically meaningful increase in fruit intake.
A 2026 analysis of 114 families in the NU-HOME rural obesity prevention trial found that while home food environment improved significantly, family meal frequency, vegetable intake, sugary drink consumption, and children’s physical activity showed no significant changes between intervention and control groups.
The Quick Take
- What they studied: Whether teaching families to improve their home food environment—like keeping more vegetables available and eating meals together—could help rural children develop healthier eating habits and be more active.
- Who participated: 114 children ages 7-10 years old from rural New Ulm, Minnesota, and their families. About 86% of families completed the full 9-month program.
- Key finding: Families who received the intervention significantly increased the vegetables they kept at home and served better quality foods at dinner compared to families who didn’t receive the program. Children in the intervention group ate about 1/3 cup more fruit daily, though this difference wasn’t quite statistically significant.
- What it means for you: Making simple changes to your home—like buying more vegetables, keeping sugary drinks out of the house, and eating dinner together—may help your kids eat better. This approach works best when the whole family is involved in making these changes together.
The Research Details
This was a randomized controlled trial, which is considered one of the strongest types of research. Researchers randomly divided 114 families into two groups: one group received the NU-HOME intervention, and the other group was placed on a waiting list (the control group). The intervention group attended 7 monthly in-person sessions where trained educators taught families practical strategies for creating a healthier home food environment. These sessions covered topics like how to stock the kitchen with fruits and vegetables, how to prepare nutritious meals, and why eating together as a family matters. Researchers measured outcomes at the start of the study and again after 9 months.
The study focused on three main areas: the home food environment (what foods are available at home and how often families eat together), children’s dietary intake (what kids actually eat and drink), and children’s physical activity (how much they move and how much screen time they get). Researchers used validated tools to measure these outcomes, including a diet quality score called the Healthy Eating Index and direct questions about food availability and family meal frequency.
This approach is important because it tests whether changing the home environment—rather than just telling kids to eat better—can actually improve their health. By working with whole families instead of just children, the program addresses the real-world factors that influence what kids eat.
Understanding which parts of a family-based obesity prevention program actually work is crucial for designing better interventions. Many obesity programs focus only on weight loss, but this study looked at the underlying factors that influence weight—like what foods are available at home and how families eat together. This approach is especially important for rural children, who may have fewer resources and less access to health programs than children in cities.
This study has several strengths: it used a randomized controlled trial design, which is the gold standard for testing whether an intervention works; it had good follow-up rates (86% of families completed the program); and it measured multiple outcomes rather than just weight. However, the study was relatively small (114 families) and conducted in one rural area, so results may not apply to all communities. The study also only lasted 9 months, so we don’t know if benefits would continue longer. Some outcomes showed improvements that weren’t quite statistically significant, meaning they could have happened by chance, though they may still be meaningful in real life.
What the Results Show
The intervention successfully improved two key aspects of the home food environment. First, families in the intervention group significantly increased the amount of vegetables they kept available at home compared to the control group. Second, the quality of foods and beverages served at evening meals improved significantly in the intervention group. These changes are important because they address the root cause of poor eating habits—when healthy foods are available and visible at home, children are more likely to eat them.
For children’s actual food intake, the results were mixed. Children in the intervention group ate about 1/3 cup more fruit per day than children in the control group, which is a meaningful amount (equivalent to about half a medium apple). However, this difference was just barely not statistically significant, meaning it could have happened by chance. There were no significant differences between groups for vegetable intake, sugary drink consumption, or physical activity levels.
The study found no significant changes in how often families ate meals together, even though this was a focus of the program. Similarly, children’s physical activity and screen time didn’t change significantly between groups. These null findings suggest that changing the home food environment alone may not be enough to increase physical activity, or that 9 months may not be long enough to see changes in these behaviors.
While not the main focus, the study provides insights into which program components were most effective. The improvements in home vegetable availability and meal quality suggest that the practical, hands-on education about stocking and preparing food was effective. The lack of change in family meal frequency is interesting—it suggests that families may have needed more support or motivation to actually eat together more often, even though they learned why it’s important. The absence of changes in physical activity suggests that the program’s physical activity component may need strengthening, or that dietary changes alone don’t automatically lead to more activity.
This study fits into a growing body of research showing that family-based interventions for childhood obesity work better than programs targeting children alone. Previous research has shown that the home food environment is one of the strongest predictors of children’s eating habits. This study confirms that improving the home environment is achievable through structured education. However, the modest improvements in actual food intake and the lack of changes in physical activity suggest that more intensive or longer interventions may be needed. Other similar studies have found that combining dietary changes with physical activity promotion and behavioral support tends to produce better results than focusing on one area alone.
Several limitations should be considered when interpreting these results. The study was relatively small (114 families) and conducted only in rural Minnesota, so findings may not apply to urban areas or other regions with different food access and cultural eating patterns. The study lasted only 9 months, which may not be long enough to see changes in some behaviors like physical activity or family meal frequency. Some improvements (like the increase in fruit consumption) were close to being statistically significant but didn’t quite reach that threshold, so they could have happened by chance. The study relied on families self-reporting what they ate and how much screen time children had, which can be less accurate than objective measurements. Finally, the study didn’t measure whether the improvements in the home food environment actually led to weight loss or other health benefits in the children.
The Bottom Line
Based on this research, families looking to improve their children’s eating habits should focus on practical changes to the home environment: (1) Stock the kitchen with plenty of fresh vegetables and fruits, keeping them visible and ready to eat; (2) Reduce or eliminate sugary drinks from the home; (3) Plan and prepare nutritious meals at home; (4) Try to eat dinner together as a family when possible. These changes appear to be achievable and meaningful, though they work best when the whole family is involved. Confidence level: Moderate—the evidence shows these changes are possible and beneficial, but the study was small and limited to one region.
This research is most relevant for families with children ages 7-10 who want to prevent obesity and establish healthy eating habits. It’s particularly applicable to families in rural areas with limited access to health programs. Parents who struggle with getting their kids to eat vegetables or who want to reduce sugary drink consumption should find these strategies practical. The findings may be less applicable to families who already have very healthy home food environments or to families with significant food insecurity, as the program assumes families have the resources to purchase fresh produce.
Changes in the home food environment can happen relatively quickly—the study saw improvements in vegetable availability and meal quality within 9 months. However, changes in children’s actual eating habits and physical activity may take longer. Families should expect to see initial changes in what’s available at home within weeks, but meaningful changes in children’s food preferences and intake may take several months as kids adjust to new foods and eating patterns.
Frequently Asked Questions
Does eating family meals together help kids eat healthier?
Research shows family meals are associated with better eating habits, but this study found that simply promoting family meals wasn’t enough to significantly increase their frequency. Families need practical support and motivation to actually eat together more often, beyond just understanding the benefits.
What’s the best way to get kids to eat more vegetables?
Making vegetables visible and available at home is key. This study found that when families increased vegetable availability in their kitchens, children’s overall diet quality improved. Keeping vegetables washed, cut, and ready to eat makes them more appealing to kids than keeping them hidden in the crisper drawer.
Can a home food environment program help prevent childhood obesity?
This study shows that improving the home food environment—what foods are available and how meals are prepared—is achievable and produces meaningful changes. However, the study didn’t measure weight loss directly, and additional strategies focusing on physical activity may be needed for complete obesity prevention.
How long does it take to see changes from improving home food habits?
This 9-month study saw improvements in home vegetable availability and meal quality within that timeframe. However, changes in children’s actual eating habits and preferences may take longer as kids adjust to new foods. Most families should expect to see initial environmental changes within weeks.
Does reducing sugary drinks at home actually change what kids drink?
This study didn’t find significant changes in sugary drink intake, even though reducing home availability was a program goal. This suggests that simply removing sugary drinks may not be enough—families may need additional strategies like teaching kids about healthier alternatives or addressing social influences on beverage choices.
Want to Apply This Research?
- Track weekly vegetable and fruit variety at home by logging the number of different produce items purchased or available in the kitchen. Set a goal to increase from current baseline to 8-10 different fruits and vegetables per week, and monitor progress weekly.
- Use the app to plan one family dinner per week where everyone eats the same meal together. Start with one meal and gradually increase frequency. Log which meals were eaten together and note any positive changes in children’s willingness to try new foods.
- Create a monthly dashboard showing: (1) types and quantities of fruits/vegetables kept at home, (2) frequency of family meals eaten together, (3) children’s reported fruit and vegetable intake, and (4) availability of sugary drinks. Track trends over 3-6 months to see if home environment improvements correlate with better eating habits.
This research describes outcomes from a single 9-month study in rural Minnesota and should not be considered medical advice. Results may not apply to all communities or populations. Parents concerned about their child’s weight, nutrition, or physical activity should consult with their pediatrician or a registered dietitian for personalized guidance. This study did not measure weight loss or other clinical health outcomes, so the long-term health benefits of these home environment changes are not yet established.
