Food Label Literacy Among School-Going Children: Knowledge, Attitudes and Practices Toward Food Label Comprehension: A Mixed-Methods Study
This mixed-methods study of urban Indian adolescents reveals that while food label literacy is moderately high, it is significantly hindered by structural barriers like language and design, as well as individual factors such as poor practices and negative attitudes, necessitating policy reforms and school-based nutrition programs.

In the modern world, food rarely comes from a garden or a farm stand; it arrives wrapped in plastic, sealed in foil, or boxed in cardboard. To navigate this landscape, governments and health organizations rely on a simple tool: the food label. This is the printed information on a package that tells a consumer what is inside, how much of it there is, and how it might affect their health. The ability to read, understand, and use this information is known as food label literacy. It is a skill that allows a person to look past the bright colors and catchy slogans on a box and see the actual nutritional content, such as the amount of sugar, salt, or fat hidden within. In countries where diets are shifting rapidly toward processed foods, this skill is becoming a vital part of public health. Without it, people may unknowingly consume foods that contribute to long-term health problems like heart disease and diabetes, simply because they cannot decipher the small print on the package.
A recent study set out to understand how well teenagers in India, a nation undergoing a rapid change in its eating habits, possess this skill. The researchers focused on adolescents between the ages of twelve and sixteen, a group that is increasingly independent in their food choices but often lacks the experience to make healthy ones. The team, based at a medical academy in the state of Andhra Pradesh, wanted to see if these young people could actually read the labels on the snacks they bought, what they thought about those labels, and whether they used that information to decide what to eat. They were particularly interested in the gap between what teenagers knew and what they actually did, and they sought to understand the barriers that stopped them from making better choices.
To get a complete picture, the researchers used a two-part approach. First, they gathered a group of thirty-six students from eight different schools for a series of informal group conversations. They asked these students to talk openly about how they looked at food packages, what confused them, and what influenced their choices. Following these discussions, the researchers designed a detailed questionnaire based on the themes that emerged. They then administered this survey to 321 students across the same schools. The survey tested the students' knowledge of label terms, their attitudes toward reading labels, and their actual habits when shopping for snacks.
The conversations with the students revealed a clear and consistent pattern. Most of the teenagers could easily find the expiration date and the small green or brown dot that indicates whether a product is vegetarian or non-vegetarian. These were the only two pieces of information they consistently looked for. However, when it came to the nutritional details, such as the list of ingredients, the amount of fat, or the percentage of daily vitamins provided, the students were largely in the dark. They described the labels as decorative rather than informative. Many admitted that the text was too small to read, the language was often English when they spoke a different regional language at home, and the abbreviations were confusing. One student noted that they only looked at the expiry date, ignoring all the numbers. Another mentioned that if a package said "low fat," they assumed it was healthy without checking the sugar content.
The students also described how their choices were driven more by social factors than by the information on the box. If a favorite celebrity appeared on a snack packet, or if a friend recommended a brand, that influence was far stronger than any warning about high sugar or salt. They felt that the advertisements on television were more trustworthy than the fine print on the back of the package. When asked what would help them understand labels better, the older students in the group spontaneously suggested a simple solution: a traffic light system. They imagined a label with red, amber, and green circles that would instantly show whether a food was unhealthy, okay to eat in moderation, or healthy. This visual cue felt intuitive and easy to understand compared to the current text-heavy panels.
When the researchers analyzed the survey results from the 321 students, the numbers confirmed the stories told in the group discussions. About 70 percent of the students had a good level of knowledge; they could answer questions correctly about what the labels meant. However, this knowledge did not translate into action. Nearly 70 percent of the students had poor practices, meaning they rarely or never used the information on the labels when choosing what to eat. In fact, not a single student in the study was classified as having "good" practices. Furthermore, half of the students held negative attitudes toward reading labels, viewing them as unhelpful or too difficult. Only about half of the students demonstrated a high level of overall food label literacy, which combines knowledge, attitude, and practice.
The study also looked at who was more likely to be literate. Students attending private schools and those whose parents had higher levels of education were more likely to understand food labels. However, when the researchers adjusted for the students' knowledge, attitudes, and habits, the influence of school type and parental education disappeared. This suggested that the root of the problem was not the family background itself, but rather the lack of understanding and the negative feelings toward the labels that often accompany it. The strongest predictors of low literacy were simply having poor knowledge, having poor habits, and holding a negative attitude. Interestingly, students who were skeptical or negative about marketing claims were actually more likely to engage with the labels, perhaps because they were more critical of the food industry.
The findings paint a picture of a generation that is aware of the existence of food labels but is blocked from using them by structural and personal barriers. The language on the packages is often inaccessible, the design is too small and cluttered, and the influence of advertising and peers overrides the information provided. The study suggests that simply teaching teenagers about nutrition is not enough if the labels themselves remain difficult to read and the environment encourages unhealthy choices. The researchers concluded that for food labels to work as a tool for health, they need to be redesigned. They should be multilingual, use larger and clearer text, and adopt simple visual systems like the traffic light colors that the students themselves requested. Additionally, stricter rules on how food is marketed to children and better nutrition education in schools are necessary to bridge the gap between knowing what is healthy and actually choosing it. The study did not prove that these changes would instantly fix the problem, but it strongly suggests that without these specific reforms, the current system will continue to fail the very people it is meant to protect.
