Experts have revealed whether six food staples and supplements really prevent colds and flu.
While honey has long been praised for reducing the symptoms of colds, science reveals it does little more than soothe sore throats.
Although an old wives tale claims chicken soup cures a host of ailments, it may simply provide a comforting meal and hydration boost, according to dietitian and British Dietetic Association spokesperson Aisling Pigott.
