Some of the UK’s most popular cereals for adults and children have a worryingly high sugar content.

Kellogg’s Coco-Pops, Crunchy Nut and Frosties all have 11-grams of sugar per 30-gram portion, that’s over two teaspoons.

We compared some of the most well-known brands by weighing out the amount of sugar in a whole box and in a 30-gram portion and the results were scary.

The NHS advises adults not to exceed more than 30-grams of added sugar a day, children should not have more than 19-grams.

Dr Alison Tedstone, chief nutritionist, Public Health England, said: “There is a role for us all in helping people eat better diets. We are working with the food industry to reduce the sugar in popular products and we have already seen some great progress. Change doesn’t happen overnight, and we will continue to monitor and encourage the industry to take action.”

Nestle and Kellogg’s told Business Insider that they are committed to reducing sugar in their cereals. 

Kellogg’s said they will have removed “2,000 tonnes of sugar by the end of 2018.”
