Perceptions of foods drive overeating more than labels like \u201cultra-processed.\u201d Researchers call for personalized approaches that address psychology and motivation in eating.<\/strong><\/p>\n

Ultra-processed foods (UPFs) are increasingly portrayed as the chief culprit in modern nutrition debates. They are linked to conditions ranging from dementia to obesity and what some describe as an epidemic of \u201cfood addiction.\u201d<\/p>\n

These industrially produced items\u2014such as chips, ready meals, fizzy drinks, and packaged snacks\u2014are frequently blamed for today\u2019s widespread health challenges. Critics argue that they are \u201cspecifically formulated and aggressively marketed to maximize consumption and corporate profits,\u201d exploiting the brain\u2019s reward systems to push us to eat more than we need.<\/p>\n

Policymakers have suggested<\/a> strong measures, including warning labels, marketing restrictions, taxes, and even outright bans near schools. But to what extent is this urgency supported by reliable evidence?<\/p>\n

My colleagues and I wanted to step back and ask: what actually makes people like a food? And what drives them to overeat \u2013 not just enjoy it, but keep eating after hunger has passed? We studied more than 3,000 UK adults<\/a> and their responses to over 400 everyday foods. What we found challenges the simplistic UPF narrative and offers a more nuanced way forward.<\/p>\n

Liking food versus overeating<\/p>\n

In nutrition research, two concepts are often confused: enjoying the taste of a food and engaging in hedonic overeating (eating for pleasure rather than out of hunger). Liking refers to flavor preference, while hedonic overeating describes the tendency to keep eating because the experience is enjoyable. The two are connected but not the same. For instance, many people enjoy porridge but rarely consume it excessively, whereas chocolate, biscuits, and ice cream are common triggers for both liking and overeating.<\/p>\n

We conducted three large online studies where participants rated photos of unbranded food portions for how much they liked them and how likely they were to overeat them. The foods were recognisable items from a typical UK shopping basket: jacket potatoes, apples, noodles, cottage pie, custard creams \u2013 more than 400 in total.<\/p>\n

We then compared these responses with three things: the foods\u2019 nutritional content (fat, sugar, fiber, energy density), their classification as ultra-processed by the widely used Nova system<\/a> \u2013 a food classification method<\/a> that groups foods by the extent and purpose of their processing \u2013 and how people perceived them (sweet, fatty, processed, healthy and so on).<\/p>\n

The power of perception<\/p>\n

Some findings were expected: people liked foods they ate often, and calorie-dense foods were more likely to lead to overeating.<\/p>\n

But the more surprising insight came from the role of beliefs and perceptions. Nutrient content mattered \u2013 people rated high-fat, high-carb foods as more enjoyable, and low-fiber, high-calorie foods as more \u201cbingeable\u201d. But what people believed about the food also mattered, a lot.<\/p>\n

Perceiving a food as sweet, fatty, or highly processed increased the likelihood of overeating, regardless of its actual nutritional content. Foods believed to be bitter or high in fiber had the opposite effect.<\/p>\n

In one survey<\/a>, we could predict 78% of the variation in people\u2019s likelihood of overeating by combining nutrient data (41%) with beliefs about the food and its sensory qualities (another 38%).<\/p>\n

Ultra-processed label limitations<\/p>\n

In short: how we think about food affects how we eat it, just as much as what\u2019s actually in it.<\/p>\n

This brings us to ultra-processed foods. Despite the intense scrutiny, classifying a food as \u201cultra-processed\u201d added very little to our predictive models.<\/p>\n

Once we accounted for nutrient content and food perceptions, the Nova classification explained less than 2% of the variation in liking and just 4% in overeating.<\/p>\n

That\u2019s not to say all UPFs are harmless<\/a>. Many are high in calories, low in fibre, and easy to overconsume. But the UPF label is a blunt instrument. It lumps together sugary soft drinks with fortified cereals, protein bars with vegan meat alternatives.<\/p>\n

Some of these products may be less healthy<\/a>, but others can be helpful \u2013 especially for older adults with low appetites, people on restricted diets, or those seeking convenient nutrition.<\/p>\n

The message that all UPFs are bad oversimplifies the issue<\/a>. People don\u2019t eat based on food labels alone. They eat based on how a food tastes, how it makes them feel, and how it fits with their health, social, or emotional goals.<\/p>\n

Relying on UPF labels to shape policy could backfire. Warning labels might steer people away from foods that are actually beneficial<\/a>, like wholegrain cereals, or create confusion about what\u2019s genuinely unhealthy.<\/p>\n
