FORGET about eggs or cereal - the traditional German breakfast of ham and cheese has been found to be the ideal start to the day.

Scientific experiments show the combination has the most significant impact on memory, work rate and attention levels.

The foods were far better than the sugared cereal with which millions of Western schoolchildren begin their day.

The scientists' analysis was based on the glycaemic load (GL) of the different breakfasts. This measures the rate at which carbohydrates release glucose into the blood stream.

 Sugary foods, such as cornflakes with two spoonfuls of sugar, accompanied by a waffle and maple syrup, had a high GL and led to a slump in performance by late morning.

Scrambled egg, bread and jam, accompanied by a yoghurt, had a medium GL score, while ham and cheese, accompanied by a low-fat spread on wholegrain bread, scored best, with a low GL.

 David Benton, a professor of psychology at Swansea University in Wales, led the research, with tests on six- and seven-year-old children.

"It's down to the glucose release of the breakfast into the bloodstream. The slower the release the better the pupils performed," he said. "It also gives pupils better memory."

The same principles apply to adults.

Professor Benton's team studied pupils who attended a breakfast club for four weeks, eating breakfasts that had high, medium and low GL but the same number of calories.

 After breakfast, hidden cameras filmed the pupils as they got on with reading, writing and arithmetic. The study found pupils who ate the high GL breakfast were prone to be disruptive, concentrated less on their work and were much more fidgety than those who had the low GL breakfast.

 Professor Benton said a low GL breakfast helped curb obesity by discouraging snacking.
