Feeling grateful for your food appears to help you eat healthier and waste less, according to Gram Research analysis of 39 studies published between 1995 and 2025. Researchers found that gratitude for food is connected to better eating choices, more mindful eating, and reduced food waste. However, scientists still need stronger research to confirm how well gratitude-based programs work for different people, as most studies so far have been small or used weaker research designs.
A new review of 39 studies shows that feeling grateful for your food is connected to eating better, wasting less food, and being more mindful about meals. Researchers looked at studies from around the world, including Japan, published between 1995 and 2025. They found that gratitude for food is a real feeling that can change how people eat. However, scientists are still figuring out the best ways to measure this gratitude and test whether programs that teach it actually work. The research suggests gratitude could be an important tool for helping people develop healthier eating habits.
Key Statistics
A 2026 scoping review of 39 studies found that gratitude for food is connected to healthier dietary behaviors, mindful eating, and reduced food waste across international research.
Researchers identified five validated gratitude for food measurement scales in the literature, though their use and validation remain fragmented across studies, limiting the ability to compare research findings.
Of the 39 studies reviewed, most intervention studies testing gratitude for food were conducted in Japan with school-aged children and used non-randomized designs, indicating a need for more rigorous research globally.
Five distinct research clusters emerged from the 39 studies: school lunches, nutrition education programs, food waste reduction, mindful eating practices, and scale development for measuring gratitude.
The Quick Take
- What they studied: Whether feeling thankful for food helps people eat better, waste less food, and think more carefully about what they eat
- Who participated: 39 different research studies from multiple countries, mostly involving school-aged children in Japan, using different research methods including surveys, experiments, and interviews
- Key finding: Gratitude for food appears connected to healthier eating choices and less food waste, but scientists need better tools to measure this feeling and more rigorous studies to prove it works
- What it means for you: Teaching yourself to feel grateful for meals might help you make better food choices and waste less, though more research is needed to confirm how well this works for different people
The Research Details
Researchers conducted a scoping review, which means they searched through many studies to understand what scientists already know about a topic. They looked through five major research databases in both English and Japanese, finding 39 studies published between 1995 and 2025. The studies they reviewed used different methods: some asked people questions about their eating habits (surveys), some tested whether teaching gratitude changed how people ate (experiments), and some interviewed people about their experiences. This approach helped them see the big picture of what research exists and what gaps remain.
The researchers carefully organized all the information they found, looking at what each study measured, how they measured it, and what they discovered. They used a computer program to analyze the main themes across all the studies, which helped them spot patterns. They also looked closely at the different tools scientists use to measure gratitude for food, checking which ones were properly tested and validated.
A scoping review is the right approach when a topic is new or scattered across many different studies. Instead of combining numbers from different studies (which would be harder here), this method helps organize what we know and shows where scientists need to do more work. This is important because gratitude for food is a newer area of study, and researchers use different methods and measurements, making it hard to compare results. By mapping out the field, this review helps future scientists know what’s already been done and what questions still need answers.
This review followed strict international guidelines (PRISMA-ScR) that ensure quality and consistency. The researchers searched multiple databases in two languages, which reduces the chance of missing important studies. However, the review included studies with different designs and quality levels, so some findings are stronger than others. The fact that only 39 studies were found suggests this is still a developing area of research. Most studies were done in Japan with school children, which means we need more research in other countries and with different age groups to know if these findings apply to everyone.
What the Results Show
The review identified five main areas where scientists have studied gratitude for food: school lunch programs, nutrition education classes, reducing food waste, mindful eating practices, and creating measurement tools. Researchers found that gratitude for food is connected to people eating healthier foods, being more aware of what they eat, and throwing away less food. However, the evidence is mixed—some studies showed strong benefits while others showed smaller effects.
The researchers discovered five different scales (measurement tools) that scientists use to measure gratitude for food. Some of these tools have been adapted for different cultures, but they’re not used consistently across studies. This fragmentation makes it hard for scientists to compare results from different research projects. Most intervention studies (experiments testing whether teaching gratitude helps) were conducted in Japan with school-aged children, and they weren’t always designed with the strongest research methods. The studies that were most rigorous (randomized controlled trials) were rare in this field.
The review found that gratitude for food is understood differently across cultures, which is important because what gratitude means in Japan might be slightly different from what it means in other countries. Studies showed that gratitude for food is connected to mindful eating—paying attention to your food while you eat. The research also suggests that programs teaching gratitude might help reduce food waste, though more evidence is needed. The review highlighted that many studies were small and didn’t use the strongest research designs, which means we can’t be completely certain about all the findings.
This is the first comprehensive review to bring together all the international research on gratitude for food. Previous research on mindful eating and food waste reduction has grown significantly, and this review shows that gratitude for food fits into both of these areas. The findings align with broader research showing that positive emotions and awareness affect eating behaviors. However, this review reveals that gratitude for food hasn’t received as much rigorous scientific testing as other eating-related topics, suggesting it’s an emerging field with lots of room for growth.
The review included studies with very different designs and quality levels, making it hard to draw firm conclusions. Most studies were done in Japan with school children, so we don’t know if these findings apply to adults or people in other countries. Many studies weren’t randomized controlled trials (the gold standard for testing whether something works), which means we can’t be completely sure gratitude causes better eating. The measurement tools for gratitude are fragmented and not always well-validated, making it hard to compare studies. The review didn’t combine numbers from studies statistically, so it’s more of a map of the field than a definitive answer about how much gratitude helps.
The Bottom Line
Based on current evidence, practicing gratitude for food appears to be a safe and potentially helpful approach to improving eating habits and reducing food waste. Moderate confidence: The connection between gratitude and better eating is shown in multiple studies, but more rigorous research is needed. Consider incorporating gratitude practices into meals—pausing to appreciate your food before eating. High confidence: This won’t hurt and may help. For schools and nutrition programs, teaching students to feel grateful for food may support healthier eating and less waste, though stronger evidence is still being built.
Anyone interested in eating healthier, reducing food waste, or developing a more mindful relationship with food could benefit from practicing gratitude. School administrators and nutrition educators should pay attention to this research as a potential tool for improving student eating habits. Parents might use gratitude practices at family meals. People with eating disorders should consult healthcare providers before using gratitude-based approaches. The research is strongest for school-aged children, so more evidence is needed for adults and older adults.
Changes in eating habits typically take weeks to months to develop. You might notice increased awareness of your food within days of practicing gratitude, but actual changes in food choices and waste reduction may take 2-4 weeks of consistent practice. Long-term benefits would likely appear over months as gratitude becomes a regular habit.
