Gram Research analysis of 417 adults in upstate New York found that hearing about the Double Up Food Bucks program through face-to-face conversations was linked to eating more fruits and vegetables than hearing about it through ads or flyers. The study cannot prove cause and effect.
According to research reviewed by Gram, people who first learned about a fruit and vegetable incentive program through face-to-face conversations tended to eat more produce than those who heard about it through ads, flyers, or other mass media. The Double Up Food Bucks New York program helps people stretch their grocery budgets for fresh produce. In this study of 417 adults in upstate New York, personal conversations were linked to higher total daily fruit and vegetable intake, with an even stronger link for whole fruits and vegetables. The study did not test whether the program itself caused people to eat more. It only looked at a snapshot in time, so it cannot show cause and effect. Still, the findings suggest that outreach through trusted community members and organizations may help more people take advantage of programs designed to improve healthy eating.
Key Statistics
A 2026 cross-sectional study of 417 participants in upstate New York found that learning about the Double Up Food Bucks program through face-to-face communication was significantly linked to higher total daily fruit and vegetable intake (standardized coefficient 0.202, P less than 0.001).
The same 2026 study found that the link between face-to-face outreach and eating produce was even stronger for whole fruits and vegetables, with a standardized coefficient of 0.228 (P less than 0.001).
The Quick Take
- What they studied: Does the way people first hear about a produce discount program, either through personal conversation or through mass media, relate to how much fruit and vegetables they eat?
- Who participated: 417 adults who took part in the Double Up Food Bucks New York program in upstate New York. Many of these people had limited incomes and faced challenges getting enough healthy food.
- Key finding: People who heard about the program face to face ate significantly more total fruits and vegetables each day than people who heard about it through mass communication. The link was stronger for whole fruits and vegetables. The reported statistical score was 0.202 for total produce and 0.228 for whole produce, with both results considered statistically significant (P less than 0.001), meaning they are very unlikely to be due to chance alone.
- What it means for you: If you run or use a nutrition program, hearing about it from a trusted friend, neighbor, or community group may make you more likely to use it and eat more produce. This study cannot prove that the conversation itself caused the change in eating, so treat the results as a promising clue rather than a final answer.
The Research Details
Researchers surveyed 417 participants who were enrolled in Double Up Food Bucks New York, a program that gives people extra money to spend on fruits and vegetables. The survey asked about basic details such as age, income, and background. It also asked how each person first learned about the program, either through a personal conversation or through broader outreach such as advertising, posters, or media.
To measure what people ate, the team used the Dietary Screener Questionnaire, a short and widely used tool that estimates typical food intake over a recent period. This tool gives a good general picture of eating habits, though it is not as precise as tracking every meal in detail.
Because everyone completed the survey at one point in time, the researchers could see which factors were connected to eating habits but could not follow people over time to see how their diets changed.
A cross-sectional design is a practical way to quickly check whether two things tend to go together across a large group. It is useful for spotting patterns that deserve further study. Because the survey captured information from many participants at once, it offers a broad look at how outreach methods relate to real eating habits in a community that programs are trying to reach.
The study used a recognized dietary tool and a sample of more than 400 people, which gives the results some credibility. Its statistical results were reported with clear measures of strength and reliability. However, the design means it cannot prove cause and effect, and people’s memories of how they first heard about the program and what they ate may not be perfectly accurate. Results from one region of New York may also not apply everywhere.
What the Results Show
The main finding was that people who first heard about Double Up Food Bucks New York through face-to-face conversations reported eating more fruits and vegetables overall than people who learned about it through mass communication. After accounting for other factors such as age and income, this link remained statistically significant. The researchers measured this link using a standardized score, where larger numbers indicate a stronger relationship. The score for total daily fruit and vegetable intake was 0.202, which the researchers reported as statistically significant at P less than 0.001.
The connection was even clearer for whole fruits and vegetables, meaning produce in its natural form rather than juice, canned goods with added ingredients, or other processed versions. The score for whole produce was 0.228, also significant at P less than 0.001. This suggests that the personal outreach was linked not just to eating more produce in general, but to choosing more of the fresh, minimally processed kind.
These results come from a survey, so they show an association rather than a direct cause. Still, the consistency of the pattern across both measures makes the finding worth attention. Personal conversations may build trust and make the program feel more relevant and easier to act on.
The study focused mainly on how people first heard about the program and their produce intake, so it offers limited information on other outcomes. The authors emphasize that awareness is a major barrier to participation in incentive programs. Many eligible people may never use a program simply because they have not heard about it in a way that feels credible. This makes the communication method itself an important part of getting programs to the people who need them.
Previous research on nutrition programs has often found that access to healthy food and financial incentives can increase fruit and vegetable purchases. This study adds to that body of work by focusing on how people learn about these programs in the first place. Community-based outreach and trusted messengers have been recognized in public health for years as effective ways to reach groups who may not respond well to general advertising, and this study appears to support that approach in the setting of produce incentives.
The most important limitation is that this was a cross-sectional study, which means it took a single snapshot of people at one point in time. It can show that personal outreach and higher produce intake tend to appear together, but it cannot prove that the conversations caused people to eat more. People who are already motivated to eat healthy may also be more likely to attend in-person events, which could partly explain the results.
Food intake was measured using a self-reported questionnaire, so participants may have overestimated or underestimated what they ate. The sample came from one region of New York, so the findings may not match the experiences of people in other states or communities. The study also did not measure the long-term effects of the program on health outcomes like blood pressure or weight.
The Bottom Line
Based on this study, program leaders and community groups may benefit from prioritizing face-to-face outreach, such as talking with people at community events, clinics, churches, and food pantries, alongside other promotion methods. Confidence in this recommendation is moderate. The association was clear and statistically strong, but because the study cannot prove cause and effect, it should be seen as a reasonable strategy supported by early evidence rather than a proven solution. Confidence would increase with longitudinal or experimental studies.
Community health workers, nonprofit leaders, nutrition program staff, and policymakers who design or fund produce incentive programs should find these results useful. People who have limited access to fresh produce and want to know about ways to stretch their food budgets may also benefit from learning about programs through trusted local sources. Individuals with specific medical conditions that affect diet, such as kidney disease or diabetes, should consult a healthcare provider before making major dietary changes.
This study measured eating habits at one point in time, so it does not show how long it takes for people to change their diets. Some people may increase their produce intake soon after joining a program, while others may need months of steady access and support. Any health benefits from eating more fruits and vegetables typically build up over months to years, so patience and consistent habits matter.
Frequently Asked Questions
How does hearing about a produce incentive program from a friend affect how much fruit and vegetables people eat?
A 2026 study of 417 adults in upstate New York found that people who first learned about Double Up Food Bucks through personal conversations ate more total fruits and vegetables daily. The link was stronger for whole produce, though the study shows association rather than proven cause.
What is Double Up Food Bucks New York?
Double Up Food Bucks New York is a program that gives people extra money to spend on fruits and vegetables when they shop. It is designed to help people with limited incomes buy more fresh produce and reduce gaps in healthy eating across communities.
Does face-to-face outreach work better than advertising for nutrition programs?
Research reviewed by Gram found that face-to-face outreach was more strongly linked to higher fruit and vegetable intake than mass communication in a group of 417 participants. Personal messages from trusted community members may build awareness and trust that ads often do not reach.
Can this study prove that talking to people about produce programs makes them eat healthier?
No single cross-sectional survey can prove cause and effect. This 2026 study of 417 people showed a clear pattern connecting personal outreach with more produce intake, but researchers recommend further studies that follow participants over time before drawing firm conclusions.
Want to Apply This Research?
- Track the number of servings of whole fruits and vegetables eaten each day, and note the source that first introduced you to any nutrition program you use, such as a friend, a community event, or an advertisement. Reviewing these entries weekly can show whether personal recommendations are linked to more produce in your own routine.
- Set a simple goal of adding one extra serving of whole fruit or vegetables to your day, and share your progress or ask a friend, family member, or community group to join you. Choose produce you can access easily, such as items from a local farmers market or a program that offers extra funds for fresh food.
- Log your produce servings for at least a few weeks, then review your average intake every month or season. Over time, track whether your intake changes after you start using new resources or join community activities. Share your summary with a healthcare provider or dietitian if you have health conditions, and update your goals as your routine becomes more consistent.
