Carbs. Sorry, Mrrzy, not what you meant (although there is the infamous burns case, the woman who won $3M-odd in compensation, having spilt her own coffee into her own lap, the court having decided that the coffee was being purveyed at a ridiculously hot temperature).

No, carbs, hot or cold, are the real danger food. The de riguer balanced diet has only been promoted since the 60's, mainly on the basis of one American who was convinced it was a good idea & was influential. We could not have evolved as we did had we been eating carbs (we'd still be in the forests with the gorillas). We did not have the modern carbs available, for a start. And there's a lot of reasons to question whether a high-carb low-fat diet (which is mostly what gets promoted) is good idea.

The "we only invented carbs *cough* agriculture 12,000 years ago" has recently been called into question, but there is nevertheless no evidence that the so-called balanced diet is healthy, bar scientific orthodoxy. Which is no different from the medieval church saying that the Earth was the centre of the universe!
