The Guideline Daily Amounts front-of-pack nutritional labelling scheme is “fundamentally flawed”, the National Heart Forum has claimed.

A report released by the charity found GDA values were not appropriate for signposting and that companies were mixing GDAs with other claims and promotional labels.

“Guideline Daily Amounts represent population goal for particular nutrients. Presenting these as percentages on the front of food packaging suggests to the consumer that these are daily targets. Without reading the small print on the back of the packet it is not clear that for fat, saturated fat, sugar and salt, these figures represent limits rather than targets,” said Jane Landon, deputy chief executive of the National Heart Forum.
