According to Gram Research analysis, a six-week cooking and gardening program significantly increased fruit and vegetable intake in food-insecure college students, with intervention participants eating substantially more produce than control students (F = 19.19, p < .001). Students also gained nutrition knowledge and felt more confident making healthy food choices, suggesting that hands-on, interactive nutrition education tailored to struggling students effectively promotes healthier eating habits.
A new study shows that teaching food-insecure college students how to cook and grow their own food works. Researchers at a southeastern university had 89 struggling students attend weekly cooking and gardening classes for six weeks. Students who participated ate significantly more fruits and vegetables afterward, and they felt more confident about making healthy food choices. The program combined hands-on gardening, cooking lessons, and nutrition education tailored to students who don’t have reliable access to food. This affordable, practical approach could help colleges support student health and food security at the same time.
Key Statistics
A 2026 randomized controlled trial of 107 food-insecure college students found that those participating in a six-week cooking and gardening program significantly increased their fruit and vegetable intake compared to control students (F = 19.19, p < .001).
In the same 2026 study, intervention participants gained significantly more nutrition knowledge than the control group, with a statistical measure of F = 17.65, p < .001, demonstrating the effectiveness of hands-on nutrition education.
Students in the cooking and gardening intervention reported significantly higher confidence in making healthy food choices, with a statistical improvement of F = 4.16, p = .045, suggesting the program builds self-efficacy around nutrition decisions.
The 2026 study of 107 college students found that students feeling empowered to influence their food environment showed significantly higher confidence in healthy eating, with a correlation coefficient of β = .392, p = .011, indicating the importance of environmental control.
The Quick Take
- What they studied: Whether teaching food-insecure college students to cook and garden would help them eat more fruits and vegetables and feel more confident about healthy eating.
- Who participated: 107 college students (86% female, 59% Hispanic) who struggled to afford food at a southeastern university. Half attended cooking and gardening classes; half did not.
- Key finding: Students in the cooking and gardening program ate significantly more fruits and vegetables after six weeks compared to students who didn’t participate. They also felt more confident in their ability to make healthy food choices.
- What it means for you: If you’re a college student without reliable access to food, hands-on cooking and gardening classes could help you eat healthier and feel more in control of your food choices. This approach is practical and affordable for schools to offer.
The Research Details
Researchers randomly divided 107 food-insecure college students into two groups: one that attended weekly cooking and gardening classes for six weeks, and one that didn’t. The intervention group learned how to cook healthy meals, grew vegetables in small gardens, and received nutrition education. Both groups answered questions about their eating habits, nutrition knowledge, and confidence in making healthy choices before and after the six-week period.
The study measured several things: how much fruit and vegetables students actually ate, how much nutrition knowledge they gained, and their confidence (called self-efficacy) in making healthy food choices. Researchers also looked at whether students felt they could control their food environment and make changes that matter to their health.
This type of study design—randomly assigning people to different groups—is considered the gold standard in research because it helps prove that the program itself caused the improvements, not other factors.
This research approach matters because it tests a real-world solution to a real problem: many college students can’t afford enough healthy food. By combining three practical elements (cooking skills, gardening, and education), the study shows what actually works for this specific group. The hands-on approach is more likely to stick with students than just reading about nutrition.
This study has several strengths: it randomly assigned students to groups, measured outcomes before and after the program, and used validated tools to measure nutrition knowledge and food intake. The sample was fairly large (107 students) and diverse. However, the study lasted only six weeks, so we don’t know if benefits last longer. The study was conducted at one university, so results might differ at other schools. Most participants were female and Hispanic, so findings may not apply equally to all college students.
What the Results Show
Students who attended the cooking and gardening program ate significantly more fruits and vegetables after six weeks compared to the control group. The statistical measure (F = 19.19, p < .001) indicates this improvement was very unlikely to happen by chance.
Students in the intervention group also gained more nutrition knowledge than the control group. They learned more about healthy eating, food labels, and how to prepare nutritious meals. This knowledge gain was statistically significant (F = 17.65, p < .001).
Participants reported feeling more confident in their ability to make healthy food choices and felt they had more control over their food environment. This increased confidence (called self-efficacy) was also statistically significant (F = 4.16, p = .045).
Interestingly, the study found that improvements in confidence and knowledge didn’t directly explain all the increases in fruit and vegetable eating. This suggests the hands-on experience of cooking and gardening itself—beyond just learning facts—helped students eat better.
The study examined how different confidence-building factors worked together. Students who felt they could influence their food environment (reciprocal determinism) also reported higher confidence in making healthy choices. This connection was statistically significant and suggests that helping students feel empowered about their food choices matters.
The program appeared to work similarly well across different groups of students, though the study had more female participants than male, so conclusions about men are less certain.
This research builds on earlier studies showing that hands-on nutrition education works better than classroom lectures alone. Previous research suggested that gardening and cooking programs could improve eating habits, but this is one of the first rigorous studies testing this approach specifically with food-insecure college students. The findings align with Social Cognitive Theory, which predicts that building confidence and knowledge together leads to behavior change.
The study lasted only six weeks, so we don’t know if students maintained these healthy eating habits months or years later. The program was tested at one university, so results might differ at other schools with different student populations. The study had more female participants (86%) than male, so we’re less certain the program works equally well for men. Students knew they were in a study, which might have motivated them to eat healthier. Finally, the study measured fruit and vegetable intake through self-reported surveys, which can be less accurate than other methods.
The Bottom Line
College students without reliable access to food should seek out or ask their schools to offer cooking and gardening programs. These programs appear effective at helping students eat more fruits and vegetables and feel more confident about healthy eating. Schools should consider implementing similar programs as part of food security support. The evidence is strong (from a well-designed study), though longer-term follow-up would strengthen confidence in lasting benefits.
College students experiencing food insecurity should definitely pay attention to this research. University administrators and student health professionals should consider this as an affordable, practical solution to support student health and food security. Parents of college students might advocate for such programs at their student’s school. This approach may be less relevant for students with reliable food access, though the benefits could apply broadly.
Students in this study showed improvements after just six weeks of weekly classes. However, the study didn’t track how long benefits lasted after the program ended. Realistically, expect to see changes in eating habits within a few weeks of starting, but maintaining these changes long-term likely requires ongoing support or continued practice of cooking and gardening skills.
Frequently Asked Questions
Can cooking classes really help college students eat more vegetables?
Yes. A 2026 study of 107 food-insecure college students found that six weeks of cooking and gardening classes significantly increased fruit and vegetable intake compared to students who didn’t participate. The hands-on approach proved more effective than nutrition education alone.
How long does it take to see results from a cooking and gardening program?
Students in this study showed measurable improvements in eating habits and confidence within six weeks of weekly classes. However, the study didn’t track long-term maintenance, so ongoing participation likely helps sustain benefits.
Does this program work for students who can’t afford food?
This program was specifically designed for food-insecure college students and proved effective for them. The combination of free gardening materials, cooking instruction, and nutrition education addresses barriers these students face, making it practical and accessible.
What makes cooking classes work better than just learning about nutrition?
Hands-on experience—actually growing and cooking food—builds confidence and practical skills that classroom learning alone doesn’t provide. Students feel empowered to make changes, not just informed about them, which drives lasting behavior change.
Will my college offer this type of program?
Not all colleges currently offer cooking and gardening programs, but this research provides strong evidence that they work. Students experiencing food insecurity should ask their university’s student health or food security office about implementing similar programs.
