Like language, clothing and logical thought, it has long set us humans apart from other animals.
However, our ability to cook could be lost within just two generations, according to a food expert.
Science writer Nicola Temple has warned that the skill may die out among the majority of Britons, in the same way the ability to sew – once considered a necessity – has dwindled in the modern world.
Mrs Temple, who has published a book on processed food, told the Edinburgh International Science Festival that its popularity can be put down to simple convenience. Those who buy ready meals and takeaways are happy to expose themselves to additives and preservatives because they have decided – for whatever reason – that they no longer have time to prepare their own meals.
In a lecture on the future of food, she said: "We're always on the go – other than the weather, we love to talk about how busy we are. But the average person in the UK watches three and a half hours of television every day so I think we need to be honest about whether we are too busy to cook or whether we just actually don't want to cook."
