AI-Generated Food Photos Flood Delivery Apps, Sparking Disappointment and Trust Concerns

Delivery apps such as Uber Eats, Deliveroo, and Just Eat are experiencing a surge in AI-generated food images, which experts warn could erode consumer trust in the restaurant industry. These artificially perfect visuals, often featuring unnaturally pristine burgers or impossibly uniform rice, are appearing on menus nationwide, leading to significant discrepancies between advertised and actual dishes.

Reporters from the Daily Mail ordered food from several restaurants with highly stylized AI-generated menu images. In many instances, the delivered meals were barely recognizable compared to the enticing online photos. While some dishes, like mozzarella sticks from Pasta Bowl and Feast, were still edible despite looking less appealing than depicted, others resulted in considerable disappointment. A rotisserie chicken burger from Five Rivers Rotisserie, for example, arrived flat and floppy, a stark contrast to its AI-generated counterpart.

Behavioral scientists note that AI-generated food images are often rated as more visually appealing than real photographs. Dr. Giovanbattista Califano, a behavioral scientist at the University of Naples Federico II, explained that generative models tend to idealize food, creating glossier, more symmetrical, and flawless images than would be captured by a standard camera. This phenomenon, where AI images act as a 'superstimulus' by exaggerating desirable qualities, can lead customers to prefer the artificial depiction over the reality.

However, the use of AI goes beyond mere enhancement. Dr. Alexander Diel, a psychologist and cognitive neuroscientist, highlighted that AI can create images of dishes that have never existed. When these images are used to represent specific restaurant offerings, the mismatch between the AI depiction and the actual food served can be substantial and misleading. An order of 'Falafel Bombs' from a restaurant called SPARTA!!!, for instance, arrived as brown, cardboard-like pucks in a cup, bearing no resemblance to the promised golden, soft balls.

The issue extends to more complex orders. A reporter ordered pancakes and 'Sweet and Sour Prawn Balls' from 'Taste of China,' a restaurant operating out of a pizza establishment. The AI-generated menu featured fluffy American-style pancakes as a side for roast duck and prawn balls resembling cake-stuffed meatballs. The actual delivery consisted of greasy fried prawns and plain duck pancakes, a significant deviation from the menu's promise.

Delivery platforms have policies regarding menu imagery. Uber Eats requires photos to accurately represent a single menu item and prohibits AI-generated images for customer-uploaded pictures. Deliveroo may reject images with obvious signs of editing, while Just Eat explicitly forbids AI-generated images and utilizes tools to filter them. Despite these guidelines, enforcement appears challenging, as evidenced by the ongoing presence of misleading AI visuals.

Industry professionals express concern over the practice. Commercial food photographers like Brent Herrig and Lindsey Kreighbaum argue that using AI to create entirely fictional dishes constitutes false advertising and dishonesty. Herrig noted that while AI can be used for legitimate enhancements, depicting a dish that was never cooked crosses a line. Kreighbaum added that customers expect to know exactly what they are ordering and that this practice severs trust between consumers and businesses.

The UK's Food Standards Agency mandates accurate labeling and marketing of food products, preventing misleading information about quality or ingredients, but does not specifically prohibit the use of AI in menu images. Food photographers worry that the proliferation of such images could devalue the entire concept of menu photography, undermining the implied promise that a pictured dish actually exists and was prepared.
