BREAKFAST cereals are "too high in sugar", according to a new report.

Consumer watchdog Which? said the majority of top-selling cereals were laden with sugar — especially those targeted at children.

Researchers for Which? found that 32 out of 50 top brands were high in sugar.

Twelve out of 14 cereals aimed at children "would be more at home in the chocolate biscuit aisle", researchers claimed.

They said that Kellogg's Frosties was the "worst offender" with 37 per cent sugar.

The consumer experts also said that cereals which were marketed as "healthy", such as Kellogg's All-Bran Bran Flakes and Special K, were also high in sugar.

Researchers said that Nestle's Shredded Wheat was the healthiest cereal, with low levels of sugar, fat and salt.

Which? executive director Richard Lloyd said: "Parents will be particularly surprised by the fact that the majority of children's cereals contain so much sugar.

"More action is needed by retailers and manufacturers to provide a wider choice of healthier cereals."

Breakfast Cereal Information Service spokeswoman Dr Gill Jenkins added: "All in all, breakfast cereals are great nutrition and a good way to start the day."
