Sri Lankan Ethnic Cuisine on YouTube: A Computational Netnographic Study of Food- Neophobic and Food-Neophilic Audience Reactions and the Digital Transmission of Culinary Heritage
This computational netnographic study of nearly 22,000 YouTube comments reveals that Sri Lankan ethnic cuisine garners overwhelmingly positive global engagement, driven by a peer-to-peer cultural translation mechanism where knowledgeable commenters mitigate food neophobia by reframing unfamiliar dishes through familiar references, thereby digitally sustaining culinary heritage.

For decades, researchers studying how people react to new foods have relied on asking travelers questions in hotel lobbies or airports. They use surveys to measure "food neophobia," a personality trait describing a natural hesitation or fear of trying unfamiliar dishes. The prevailing idea has been that people are either cautious about new tastes or eager for them, and that this caution usually stops them from enjoying a destination's local cuisine. But these surveys have a blind spot: they capture a single moment in time and ask people to guess how they might feel, rather than watching how they actually react when they see food they don't recognize. In the last few years, a massive shift has occurred in how we encounter food. Before ever visiting a country, millions of people now watch videos of street food, home cooking, and travel tours on platforms like YouTube. These videos are no longer just promotional clips; they have become the primary way global audiences learn about and engage with the culinary heritage of places like Sri Lanka. This new digital landscape offers a rare opportunity to listen to real, unscripted conversations between strangers, revealing how people actually process the shock of the unfamiliar and how they might overcome it together.
A researcher named Rohan Laksiri decided to listen to these conversations to see what they could teach us about food fear and food love. He focused on Sri Lanka, an island nation with a complex culinary history shaped by centuries of trade and colonization, resulting in a cuisine that blends South Indian roots with Arab, Portuguese, Dutch, and British influences. Laksiri gathered nearly 22,000 English-language comments left under 45 different YouTube videos about Sri Lankan food. These videos ranged from quick, one-minute clips to long, detailed travelogues, and they were posted by a mix of international travel stars, local creators, and Sri Lankans living abroad. Instead of asking people to fill out a questionnaire, Laksiri used computer tools to scan the text of these comments for specific words that signal fear or excitement. He looked for markers of hesitation, such as words like "scared," "dirty," or "weird," and contrasted them with markers of enthusiasm, such as "delicious," "must try," or "amazing." He also used a method to group the comments into eight main themes, allowing him to see not just how people felt, but what they were actually talking about when they felt that way.
The results challenged the old assumption that fear and excitement are opposites that cancel each other out. In the comments, words of enthusiasm appeared far more often than words of fear, outnumbering them by about seven to one. However, the most revealing finding was that these two feelings often existed in the same sentence. About one and a half percent of the comments contained both fearful and excited language. When a person wrote something like, "It looks a bit unhygienic, but I would still love to try it," the overall tone of the comment was usually positive. The fear was present, but it was a minor hesitation that did not stop the excitement. This suggests that being afraid of new food and being eager to try it are not two sides of the same coin, but rather two separate feelings that can happen at the same time. Furthermore, the fear did not cluster around just one type of video or one specific dish. Instead, concerns about hygiene, spice levels, or strange ingredients appeared scattered across every topic the researchers identified, from street food challenges to traditional desserts.
Perhaps the most significant discovery was how the audience helped each other navigate these unfamiliar foods. The comments were not just a collection of individual opinions; they functioned as a living, digital conversation where knowledgeable people explained the culture to those who were confused. When a viewer expressed confusion or disgust about a traditional practice, such as chewing betel leaf or eating with their hands, other commenters—often Sri Lankans or people from the region—would step in to explain the history, the preparation, and the proper etiquette. They would translate the unfamiliar into something familiar, comparing a Sri Lankan dish to a known food from their own culture to make it less intimidating. This process, which the researcher calls "peer-to-peer cultural translation," acts as a modern form of oral tradition. In the past, food knowledge was passed down in families or villages, but now, this same kind of teaching happens in the comment sections of videos, reaching millions of viewers and staying there for years. It turns out that the audience does more than just watch; they actively teach each other how to appreciate the food, effectively reducing the fear of the unknown before it can take hold.
The study also found that the length of the video mattered. Short, fast-paced clips tended to generate quick, neutral, or transactional comments, while longer, more detailed videos sparked stronger reactions, both positive and negative. The longer format gave viewers more time to process the food and the culture, leading to more polarized responses. This suggests that while short videos are good for building general awareness, longer videos are better for deep engagement and for the kind of detailed cultural exchange that helps overcome hesitation. The research concludes that digital platforms are not just marketing tools but are now a central part of how culinary heritage is preserved and shared. The comments section has become a vital space where the meaning of ethnic food is negotiated, defined, and passed on to the world. By listening to these conversations, we can see that the transmission of food culture is a collaborative effort, where the curiosity of the outsider is met with the patience and knowledge of the insider, creating a new way for the world to taste and understand Sri Lanka.
