Top chef Raymond Blanc has described the suggestion that brown toast could cause cancer as 'a dumb thing to say'.

Earlier today the Food Standards Agency (FSA) said people were consuming too much acrylamide, a chemical that is produced naturally when starchy foods are cooked at high temperatures.

As a result eating crisps, well-browned roast potatoes and toast that is more than lightly grilled could increase the risk of cancer.

But Mr Blanc, who runs Le Manoir Aux Quat'Saisons in Great Milton, said you would need to eat 1kg of burnt toast a day to be at a greater risk of cancer.

The FSA said it did not want to scare people but that there was a risk.

There are no regulatory maximum limits for acrylamide in food.
