A new study published in Scientific Reports suggests that people who report greater gratitude also tend to have healthier dietary patterns, including higher consumption of organic and plant-based foods. The findings, drawn from the NutriNet-Santé study, add to a growing body of research exploring how psychological wellbeing may shape everyday food choices.
What the researchers found
The cross-sectional analysis examined associations between gratitude and dietary factors such as overall diet quality, food group intake, ultra-processed foods, and organic and plant-based foods. The researchers used the French National Nutrition and Health Program Guideline Score to assess adherence to dietary guidance, and they reported that gratitude was associated with a healthier diet profile overall.
While the study does not prove that gratitude directly causes people to eat better, it raises the possibility that positive emotional traits may be linked to more nutritious eating patterns. The authors also noted that the relationship extended beyond general diet quality and included higher intake of organic and plant-based foods.
Why it matters for diet and nutrition
The findings are relevant to ongoing discussions about how mental and emotional health interact with nutrition. In practice, diet is often studied through the lens of nutrients, food groups, and disease risk, but this research points to the role of behaviour and mindset as potential contributors to food choices as well.
That could matter for public health approaches that aim to improve eating habits. If emotional wellbeing and gratitude are connected to healthier food selections, then nutrition strategies may benefit from considering psychological as well as dietary factors.
A cautious interpretation
Because the study was cross-sectional, it captures associations at a single point in time rather than proving a cause-and-effect relationship. That means it is not possible to say from this research alone whether gratitude leads to healthier eating, whether healthier eaters tend to feel more grateful, or whether another factor influences both.
Even so, the study adds a timely angle to nutrition research by suggesting that diet quality may be tied to more than access, price, or preference. It may also reflect broader lifestyle patterns that are increasingly being examined in nutrition science.
For readers and clinicians alike, the message is not that gratitude is a substitute for dietary guidance, but that wellbeing and nutrition may be more closely linked than often assumed.
