A new study looked at a cooking program called Not-Just-Supper Club that teaches cancer survivors how to prepare healthy, plant-based meals. Researchers found that people who participated felt happier, more connected to others, and made better food choices. About 93% of the 41 people in the program said it had a positive impact on their lives. The longer people stayed in the program, the more nuts and plant-based foods they ate. This research shows that teaching cooking skills and bringing people together over meals can be just as important as giving nutrition advice to cancer survivors.
The Quick Take
- What they studied: Whether a community cooking program for cancer survivors helps them eat better foods, learn cooking skills, and feel more connected to others.
- Who participated: 41 cancer survivors (mostly women) who attended a cooking program called Not-Just-Supper Club at Gilda’s Club Toronto. The group was diverse in terms of ethnicity and background.
- Key finding: Nearly all participants (93%) said the program helped them, and two-thirds reported eating healthier. People who stayed longer in the program ate more nuts and plant-based foods over time.
- What it means for you: If you’re a cancer survivor or know someone who is, cooking classes that focus on healthy plant-based meals may help improve eating habits and emotional well-being. However, this was a small study, so more research is needed before making it a standard recommendation.
The Research Details
Researchers used a mixed methods approach, which means they combined two types of research. First, participants filled out a food survey asking about the types of protein foods they ate since joining the cooking program. Then, researchers interviewed 40 of the 41 participants to ask deeper questions about how the program changed their eating habits, their confidence in cooking, and how it affected their social connections. The researchers looked for patterns in both the survey numbers and the interview stories to understand how the program worked.
This approach is useful because it captures both measurable changes (like eating more nuts) and personal experiences (like feeling less lonely). The researchers used statistical analysis to see if people who stayed in the program longer ate differently than those who just started.
Most nutrition research for cancer patients focuses on preventing cancer or managing side effects through diet. This study is important because it looks at something different: teaching people how to actually cook healthy meals and bringing them together as a community. This addresses a real gap—knowing what to eat is different from knowing how to prepare it. The study also recognizes that cancer survivors often feel isolated and stressed, and sharing meals together can help with emotional health, not just physical health.
This study has some strengths and limitations to consider. The strength is that it combined numbers with personal stories, giving a fuller picture. The researchers also adjusted their statistical analysis to account for other factors that might affect eating habits. However, the study is relatively small (41 people) and mostly included women, so the results may not apply equally to everyone. The study also relied on people remembering what they ate, which can be less accurate than other methods. Since this is a new program, there’s no comparison group to see if the same changes would happen without the program.
What the Results Show
The main finding was that the cooking program had a positive impact on nearly all participants. When asked directly, 38 out of 41 people (93%) said the program helped them, and 27 out of 41 (66%) reported that their eating habits improved. These are strong numbers suggesting the program was well-received.
When researchers looked at specific foods, they found that people who stayed in the program longer ate more nuts. For every year someone participated, they ate about half a serving more nuts per day on average. This might seem small, but nuts are very nutritious and this shows the program was actually changing what people ate.
The interviews revealed seven main ways the program helped people. On the emotional and social side, people felt less lonely, got more support from others, felt better mentally, and reported improvements in their overall health and cancer-related symptoms. On the practical side, people learned cooking skills, felt more confident making food choices, and started eating more plant-based foods like vegetables, beans, and grains.
Participants described taking what they learned in class and using it at home. They talked about trying new recipes, feeling proud of their cooking, and enjoying meals with family and friends. Many mentioned that the program helped them during a difficult time in their lives.
Beyond the main findings, the interviews revealed important details about how the program worked. Participants appreciated learning about nutrition in a hands-on way rather than just hearing advice. They valued the social connections they made with other cancer survivors who understood their experiences. The program also seemed to help people feel more in control of their health during a time when cancer treatment can make people feel helpless. Some participants mentioned that the program helped with cancer-related side effects like loss of appetite or difficulty eating certain foods.
This study fills a gap in cancer nutrition research. Most previous studies focus on whether certain diets prevent cancer or help manage treatment side effects. This research is different because it looks at how teaching cooking skills and building community can support cancer survivors. The findings align with broader research showing that social connection and feeling capable (called ‘self-efficacy’) are important for health. The emphasis on plant-based foods matches current nutrition guidelines for cancer survivors, which recommend eating more vegetables, fruits, and whole grains.
Several limitations should be considered. First, the study only included 41 people, mostly women, so results may not apply to all cancer survivors, especially men. Second, there was no control group—researchers didn’t compare this program to people who didn’t participate, so some improvements might have happened anyway. Third, people reported their own eating habits from memory, which can be inaccurate. Fourth, the study doesn’t tell us which parts of the program were most helpful (the cooking, the social connection, or the nutrition education). Finally, the study only measured short-term changes, so we don’t know if people keep eating healthier long-term after the program ends.
The Bottom Line
Based on this research, community cooking programs for cancer survivors appear promising and may be worth trying if available. The evidence suggests these programs can help with both eating habits and emotional well-being. However, this should complement, not replace, medical care and nutrition advice from healthcare providers. More research with larger groups is needed before making strong recommendations. If you’re interested in a program like this, talk to your cancer care team or local cancer support organizations about what’s available in your area.
This research is most relevant for cancer survivors looking for support with nutrition and emotional health. It may also interest family members and friends who want to help. Healthcare providers working with cancer patients should consider how cooking programs might fit into their care plans. Cancer support organizations and community centers may find this helpful when planning programs. However, people with severe swallowing difficulties or other eating complications should work with their medical team before joining a cooking program.
Based on the study, people who participated longer saw more changes in their eating habits, suggesting benefits build over time. Most participants reported feeling better emotionally fairly quickly, but changes in actual eating patterns seemed to develop over weeks and months of participation. You shouldn’t expect overnight changes—think of it as a gradual process of learning new skills and building healthier habits.
Want to Apply This Research?

- Use the app to save favorite recipes from the cooking program and create a weekly meal plan. Set reminders to try one new plant-based recipe each week and log when you cook it. Share your meals with others in your support network through the app to maintain social connection.
- Track your food intake monthly using a simple food diary in the app, focusing on plant-based foods and nuts. Also log how you’re feeling emotionally and any changes in cancer-related symptoms. Review your progress every month to see patterns and celebrate improvements in both eating habits and well-being.
This research describes the experiences of one community cooking program and should not replace medical advice from your healthcare team. If you’re a cancer survivor, consult with your oncologist or registered dietitian before making significant dietary changes, especially if you’re undergoing treatment or have specific nutritional needs related to your cancer or medications. This study is observational and cannot prove that the cooking program caused the improvements—other factors may have contributed. Individual results may vary, and this program may not be appropriate for everyone.
