Some ultra-processed foods are packed with artificial colours and flavourings. But scientists have found that food which is 100 per cent artificial looks even tastier than the real deal. Researchers from the University of Oxford and the University of Naples Federico II discovered that people rate AI-generated food images are more appetising. And, as AI images become more realistic, the experts warn that they could even promote unhealthy eating habits. So, can you separate the real photos from their AI copies?

Those who are a stickler for etiquette should look away now. That's because we've all been dining the wrong way and should be eating with our hands, according to a psychologist. Professor Charles Spence, from the University of Oxford, said giving up cutlery is the secret to enjoying food.

'We've been doing it all wrong,' said Charles Spence, a Professor of Experimental Psychology. 'Parents instil manners in their children, extolling the virtues of politely chewing with our mouths closed.
