Research shows that people who are skilled at using online grocery shopping and finding nutrition information online tend to eat healthier diets. A 2026 cross-sectional study of 196 adults in a low-income Connecticut community found that digital food literacy skills explained about 54% of the variation in diet quality, with online nutrition information and grocery shopping skills showing the strongest connections to healthier eating patterns.
Researchers created a new survey to measure how well people can use the internet to make healthy food choices, especially in neighborhoods without easy access to fresh food. They tested this survey with 196 adults from a low-income community in Connecticut and found that people who were better at using online tools for grocery shopping and finding nutrition information tended to eat healthier diets. The study suggests that teaching people digital food skills could be a practical way to help communities improve their eating habits when healthy food options are hard to find nearby.
Key Statistics
A 2026 cross-sectional study of 196 adults from a low-income community in Northeast Connecticut found that digital food and nutrition literacy skills explained 53.8% of the total variance in diet quality measures.
According to research reviewed by Gram, online nutrition information and online grocery shopping components showed the strongest associations with diet quality adequacy scores among 196 low-income adults studied in 2026.
A 2026 study of 196 participants found that a 10-item Digital Food and Nutrition Literacy survey identified three distinct components related to healthier eating: online grocery shopping, online nutrition information, and online food communication.
The Quick Take
- What they studied: Whether people’s ability to use the internet for food shopping and nutrition information connects to eating a healthier diet
- Who participated: 196 adults living in a low-income neighborhood in Northeast Connecticut where fresh food is hard to find
- Key finding: People who were skilled at using online grocery shopping and finding nutrition information online had better diet quality scores. Online nutrition information skills showed the strongest connection to healthier eating.
- What it means for you: If you live in an area without good access to fresh food, learning to use online grocery services and nutrition websites might help you eat better. This is still early research, so it’s not a guaranteed solution, but it shows promise as one tool to improve diet quality.
The Research Details
Researchers created a 10-question survey called the Digital Food and Nutrition Literacy survey to measure how well people can use the internet for food choices. They based the survey on two established theories about how people make decisions and learn new skills. The survey asked about three main areas: using online grocery shopping, finding nutrition information online, and talking with others online about food. All 196 participants completed the survey online and also answered questions about what they typically eat. The researchers then used statistical analysis to see if people with stronger digital food skills also had healthier diets overall.
This research approach is important because it creates a new tool that can measure a specific skill that hasn’t been well-studied before. By testing whether this skill connects to actual diet quality, the researchers showed that digital food literacy is worth paying attention to. This matters especially for people in underresourced communities where traditional grocery stores may be far away but internet access is available.
The survey was carefully designed based on established theories and tested for reliability, meaning it measures what it’s supposed to measure consistently. The study included a reasonable sample size of 196 people from the target community. However, this is a snapshot study, not a long-term follow-up, so it shows connections but not whether improving digital skills actually causes better eating. The study was limited to one region, so results may not apply everywhere.
What the Results Show
The 10-item Digital Food and Nutrition Literacy survey successfully measured three distinct skills: online grocery shopping, finding nutrition information online, and online food communication. These three components together explained about 54% of the differences in diet quality among participants, which is a substantial amount. The strongest connections appeared between online nutrition information skills and diet quality, and between online grocery shopping skills and diet quality. People who scored higher on these two components tended to have better overall diet quality scores on both measurement tools used in the study.
The online communication component (talking about food with others online) showed weaker connections to diet quality compared to the other two skills. This suggests that learning where to find good nutrition information and how to use online grocery services may be more directly helpful for eating better than social aspects of online food discussion. The study found these patterns held true across two different ways of measuring diet quality, which strengthens confidence in the findings.
This research fills a gap because very little prior work has measured digital food literacy as a specific skill. Previous studies focused on general nutrition knowledge or internet use, but not specifically on using digital tools for food choices. This study shows that digital skills are a distinct area worth studying separately. The findings align with broader research showing that access to information and tools influences food choices, but extends this to the digital realm where many people now shop and learn about nutrition.
The study only included 196 people from one area of Connecticut, so results may not apply to other regions or communities with different internet access or demographics. Because this is a snapshot study, researchers cannot prove that better digital skills cause better eating, only that they go together. The study relied on people self-reporting what they eat, which can be less accurate than other methods. The research doesn’t tell us whether teaching people these digital skills would actually improve their diets over time.
The Bottom Line
According to Gram Research analysis, community health programs should consider assessing digital food literacy as part of nutrition interventions, particularly in low-income areas. Teaching people how to use online grocery services and find reliable nutrition information online may help improve diet quality. This approach appears most promising for people who have internet access but limited access to physical grocery stores. Confidence in these recommendations is moderate because this is early research and long-term studies are needed.
This research matters most for people living in neighborhoods without easy access to fresh food but with reliable internet access. Community health workers, nutrition educators, and public health programs serving low-income populations should pay attention to these findings. People who prefer online shopping or want to improve their diet through digital tools may find this helpful. Those with limited internet access or who prefer in-person shopping may find less value in these specific recommendations.
Realistic improvements in diet quality from learning digital food skills would likely take weeks to months to become noticeable, as people need time to practice new skills and see changes in their shopping and eating habits. This is not a quick fix but rather a gradual skill-building process. Long-term benefits would depend on consistently using these digital tools over time.
Frequently Asked Questions
Does learning to use online grocery shopping help you eat healthier?
Research from a 2026 study of 196 adults suggests yes. People skilled at online grocery shopping had better diet quality scores. However, this shows a connection, not proof that learning these skills will definitely improve your diet.
What online food skills matter most for eating better?
A 2026 study found that finding nutrition information online and using online grocery services showed the strongest connections to diet quality. Learning to search for reliable nutrition facts and navigate online stores appears most helpful.
Can digital food literacy help people in food deserts?
Research suggests it may help. A 2026 study of 196 people in a low-food-access community found digital skills connected to better diet quality, offering a potential tool when physical grocery stores are far away.
How long does it take to see diet improvements from digital food skills?
The 2026 study was a snapshot, so it doesn’t show timing. Realistically, building new digital skills and seeing diet changes would likely take weeks to months of consistent practice.
Is this research proven to work for everyone?
Not yet. The 2026 study included 196 people from one Connecticut community, so results may not apply everywhere. More research is needed to confirm these findings in different populations.
