The model, which underpins Ofcom's ban on advertising junk food to kids, rates all foods on the basis of a 100g portion. This means it classifies many wholesome and nutritious foods eaten in far smaller quantities - such as cereals, cheese, marmite and raisins - as high fat, salt and sugar foods, which means they can't be advertised during children's programming.
However, the panel did recommend a change to the way the NPM calculates protein scores and for the FSA and Ofcom to consider how the model could be applied to ads that feature recipes.
The inconsistencies in the FSA's nutrient profiling model were the subject of the high profile Weigh It Up! campaign, launched by The Grocer last year, which called for an urgent review of the model.
