Behavioural Determinants of Artificial Intelligence-Support Nutrition Information Use Among Adolescents in Ibadan, Nigeria: A cross-sectional study
This cross-sectional study of 422 adolescents in Ibadan, Nigeria, reveals that AI nutritional literacy, trust, and acceptance are significant positive determinants of AI-supported nutrition information use, whereas preference shows an inverse association.

In the modern world, the way young people learn about their health is shifting rapidly. For decades, nutrition education relied on teachers, parents, and printed pamphlets, but today, many adolescents turn to digital tools for answers. Among these tools, artificial intelligence has emerged as a powerful force. In simple terms, this technology refers to computer systems designed to mimic human thinking, capable of learning from data, solving problems, and offering personalized advice. When applied to nutrition, these systems can act as virtual dietitians, tailoring meal plans and health tips to an individual's specific needs. However, simply having access to this technology does not guarantee that young people will actually use it. Just as a library full of books is useless if no one knows how to read or feels safe entering the building, an intelligent nutrition app is ineffective if the user does not trust it, does not understand how it works, or does not feel comfortable using it. Understanding these human feelings and habits is crucial, especially in regions where digital access is growing but the social and psychological landscape is still catching up.
A recent study conducted in Ibadan, Nigeria, set out to explore exactly these human factors. Researchers wanted to know what drives teenagers to actually engage with AI-supported nutrition information. They focused on a specific group of 422 adolescents, ranging from 10 to 19 years old, who were attending secondary schools and universities in the city. The team gathered data through structured questionnaires, asking the young people about their knowledge of AI, how much they trusted these systems, whether they found them acceptable, and how often they used them for dietary advice. The researchers then used advanced statistical methods to map out the connections between these different feelings and behaviors, looking for the specific ingredients that turn a passive observer into an active user.
The results revealed a clear picture of what matters most. The study found that the single strongest predictor of whether an adolescent would use AI for nutrition advice was their level of acceptance. If a young person believed the technology was useful and easy to use, they were significantly more likely to engage with it. This finding held true regardless of other factors, suggesting that the perception of value is the primary gatekeeper. Interestingly, the study also uncovered a surprising nuance regarding trust. While trust in the AI system was high among many participants, it did not directly cause them to use the information on its own. Instead, trust worked behind the scenes; it built a foundation of confidence that made the adolescents more willing to accept the technology in the first place. Once that acceptance was established, the actual usage followed.
Another critical factor identified was AI nutritional literacy. This term describes a young person's ability to understand, interpret, and critically evaluate information generated by artificial intelligence. The study showed that this skill had a powerful, direct impact on usage. Adolescents who possessed a better grasp of how AI works and how to read its outputs were more likely to use the information effectively. This suggests that knowing how to navigate the digital world is just as important as trusting the tools within it. The researchers also looked at personal preference, finding that while a general liking for AI tools was associated with usage in initial checks, it was not a standalone driver when all other factors were considered together. This implies that preference alone is not enough to sustain engagement; it must be supported by acceptance and understanding.
The study also highlighted the role of age. The data indicated that younger adolescents were slightly more likely to engage with these AI nutrition tools than their older peers. This difference may stem from a natural curiosity and openness to new technologies that tends to be stronger in early adolescence, whereas older teenagers might face more academic pressures or become more selective about their information sources. The researchers noted that while the study provided a robust snapshot of these behaviors, it was conducted at a single point in time, meaning it captures a moment in the lives of these students rather than a long-term trend.
Ultimately, this research offers a clear roadmap for anyone hoping to improve nutrition education through technology. It suggests that simply building better apps or providing more internet access is not the complete solution. To truly reach adolescents, developers and educators must focus on making the technology feel useful and easy to use, thereby fostering acceptance. They must also ensure that young people are taught the skills necessary to understand and evaluate AI-generated advice. By combining these elements—building trust to encourage acceptance, and teaching literacy to ensure competence—interventions can move beyond mere availability to create meaningful, lasting engagement with healthy eating habits. The findings from Ibadan serve as a reminder that in the age of artificial intelligence, the human mind remains the most important variable.
