Ebenezer Scrooge tried to wave away the ghost of Jacob Marley by blaming the apparition on “an undigested bit of beef … a crumb of cheese”. Charles Dickens might have been writing fiction, but the idea that late-night dairy can warp dreams has now gained scientific support.
Researchers in Canada surveyed 1,082 university students about their eating habits, sleep patterns and dreams. Remarkably, 40% reported that certain foods affected their sleep. Of that group, 20% blamed dairy – suggesting that Scrooge’s midnight cheese might have had more of an impact than he realised.
