Kellogg's UK has responded to concerns about childhood obesity by reducing the sugar content in Frosted Flakes from 38% to 25%. So, like, a 500g box of frosted flakes is one-quarter sugar? And that's the new, improved flakes?
Aubrey Sheiham, professor of dental and public health at University College London said that products high in very refined starch were often just as bad on the index as those high in sugar.
Reducing the sugar from 38% to 25% was unlikely to help in terms of tooth decay either. "When you have very finely milled starch and sugar together the effect on teeth can be worse than sugar, perhaps because of the stickiness," he said.
