Eating habits appear to be shaped by identity, culture, access, and confidence, not just knowledge of nutrition. According to Gram Research analysis of a 2026 Journal of the American Heart Association study, 14 people managing diet-related conditions identified 15 subthemes grouped into 3 themes. They recommend building strong support systems and culturally relevant education into food programs.
Gram Research analysis of a 2026 study in the Journal of the American Heart Association finds that changing how we eat is shaped by far more than knowing what is healthy. Researchers worked with a Lived Experience Patient Advisory Group of 14 people managing diet-related chronic conditions. Participants completed surveys, kept daily food diaries, took part in individual interviews, and joined a 2-day in-person workshop. Their experiences grouped into 3 main themes: facing change, understanding barriers, and acting. Identity, social norms, access to food, and confidence in one’s own abilities all appeared to influence daily food choices. The group suggested stronger support systems, culturally relevant education, and coordinated help from health care, communities, and policymakers. The findings suggest that food programs may work better when they are designed around people’s real lives.
Key Statistics
A 2026 participatory study published in the Journal of the American Heart Association involved 14 adults managing diet-related chronic conditions and found that food choices are shaped by identity, social norms, access, and self-efficacy.
Across surveys, daily food diaries, individual interviews, and a 2-day in-person workshop, a 14-person lived experience advisory group produced 15 subthemes grouped into 3 main themes: facing change, understanding barriers, and acting.
The Quick Take
- What they studied: The researchers wanted to understand what people with diet-related health conditions experience when they try to change how they eat, including the emotional, cultural, and practical factors that affect those choices.
- Who participated: A group of 14 adults managing conditions linked to diet, such as heart and metabolic diseases. The group was intentionally diverse, and members helped shape the study as advisors.
- Key finding: Participants described food choices as deeply personal and shaped by identity, social norms, access, and confidence. Their input formed 15 smaller subthemes, which were grouped into 3 larger themes: facing change, understanding barriers, and acting.
- What it means for you: If changing your diet feels hard, the difficulty may come from more than willpower. Support from family, communities, and health care, along with education that fits your culture and daily routine, may make healthier eating easier to sustain. Because this was a small group study, these ideas are worth exploring rather than treating as proven fixes.
The Research Details
This study used participatory action research, an approach where the people affected by a problem help shape the research itself. The researchers formed a Lived Experience Patient Advisory Group, a team of people who manage diet-related conditions in their own lives. Their goal was to hear the stories behind food choices rather than only measure what people eat.
The group took part in several steps. Participants filled out surveys, recorded their daily food intake in food diaries, and completed individual interviews to share personal stories. They then came together for a 2-day in-person workshop to discuss barriers, identify what motivated them, and suggest possible solutions.
The researchers used a method called thematic analysis to review all of this material. This means they read through the responses, looked for repeated ideas, and organized them into themes. The result was 15 subthemes that were grouped into 3 broader themes.
Most nutrition programs are designed by researchers and clinicians before anyone asks patients what would actually help. By listening first, this approach captures the real-world reasons people do or do not change their eating habits, such as cultural traditions, money worries, family routines, and feelings of confidence. These insights can help program designers avoid solutions that look good on paper but do not fit everyday life.
The study has several strengths. It involved people with lived experience in the design and analysis, used multiple ways of gathering information (surveys, diaries, interviews, and a workshop), and was published in a peer-reviewed journal. Readers should keep in mind that it included only 14 participants and focused on understanding experiences rather than measuring health outcomes. The findings describe patterns in a small group and are best viewed as a starting point for further research and program design.
What the Results Show
The main result was that changing food habits appears to be a deeply personal process. Participants described eating as tied to who they are, what their families and communities expect, what foods they can easily get, and how capable they feel of making a change. Knowing that a food is healthy was not described as enough on its own.
The analysis produced 15 subthemes, which were grouped into three larger themes. The first, facing change, covered the emotional experience of recognizing that eating habits need to shift, including fear, frustration, and motivation. The second, understanding barriers, described the obstacles participants faced, such as cost, access to fresh food, cultural expectations, and time pressures. The third, acting, focused on what participants said helps them take steps forward.
Participants also proposed a framework of possible intervention points. Their ideas centered on support systems, education that reflects cultural backgrounds and food traditions, and alignment across health care, community organizations, and policy. The group emphasized that no single person or organization can solve the challenge alone.
Participants stressed that support from other people made a difference in their ability to make dietary changes. Feeling understood, rather than judged, appeared to matter. The group also highlighted that education works best when it respects a person’s culture and daily routines, instead of asking them to abandon familiar foods entirely. These points suggest that programs built around one-size-fits-all advice may miss important needs.
This study adds to a growing body of research suggesting that diet programs are more successful when they consider social, economic, and emotional factors. Earlier work on food as medicine programs has often focused on whether patients receive healthy food or nutrition counseling. This study goes a step further by showing how identity, community, and confidence shape whether those supports actually lead to lasting change.
The most important limitation is the small size of the group, with only 14 participants. Their experiences may not reflect the views of everyone living with diet-related conditions, particularly people in other regions, age groups, or cultural communities that were not represented. Because the study was designed to explore experiences in depth, it did not measure changes in diet, weight, blood pressure, or other health outcomes. Participants who chose to join an advisory group may also differ from the wider patient population. Future studies with larger and more varied groups, along with outcome measurements, would help show which ideas hold up in practice.
The Bottom Line
Based on this study, programs that help people change their diet may benefit from building in strong peer and family support, culturally relevant education, and coordinated help from health care, community groups, and policymakers. Confidence in these recommendations is moderate, since they come from thoughtful input from a small group rather than from large trials showing health results. Anyone making changes to their diet should work with their health care team, especially if they take medications or have a chronic condition.
People managing diet-related conditions, families and caregivers, health care teams, community organizations, and those who design or fund Food Is Medicine programs may find these insights useful. People without a diet-related health concern may still find the ideas about identity, culture, and support helpful for building lasting habits. Anyone with a medical condition should consult a clinician before making major dietary changes.
This study did not measure how long it takes to see health benefits from changes in eating habits. In general, many people who improve their diets over several months may notice changes in energy and routines first, while changes in lab results or blood pressure often take longer and vary from person to person. Setting realistic, gradual goals and reviewing progress with a health care provider can help set expectations.
Frequently Asked Questions
Why is it so hard to change what I eat even when I know it’s healthy?
A 2026 study in the Journal of the American Heart Association found that food choices are shaped by identity, social norms, access, and self-efficacy, which means confidence in your own abilities. The 14 participants described emotional, cultural, and practical barriers that influenced their daily meals beyond simple knowledge of nutrition.
What is Food Is Medicine?
Food Is Medicine refers to programs that use healthy, nutritious food and related support to help people manage conditions linked to diet, such as heart and metabolic diseases. The American Heart Association’s Health Care by Food initiative aims to strengthen these programs by building in insights from people living with these conditions.
What helps people stick with healthier eating, according to research?
A 2026 study of 14 people with diet-related conditions suggested that support systems, culturally relevant education, and coordinated help from health care, community groups, and policymakers may support lasting dietary change. Because the group was small and the study explored experiences rather than measuring health results, these ideas need further testing.
Want to Apply This Research?
- Log meals for two weeks and note the time, the setting (home, work, restaurant), and a one-word emotional state, such as stressed, rushed, or comfortable. Track how many days per week you eat a meal you planned in advance. These simple, measurable entries can reveal the personal patterns that the study identified as important.
- Choose one barrier from your log, such as eating out too often or not having fresh food at home, and set one small, specific goal to address it. For example, plan two home-cooked meals per week that use familiar foods from your culture. Invite one person to join you for a weekly check-in so you have support.
- Review your logs monthly to spot changes in patterns rather than focusing on perfect days. Note which support people or resources made the biggest difference and adjust your plan accordingly. Share summary reports with your health care team at regular visits to connect your daily habits with clinical goals.
