The ban on television advertising for products high in fat, salt and sugar to children will be extended to all new and non-broadcast media should the Tories win the next election.

However, the controversial nutrient profiling model, developed by the FSA to help advertising watchdog Ofcom rate products, could be replaced with a new single system that would guide all policy areas.

These are just two of 48 proposals included in the new 'We're all in this together' report from the Public Health Commission.

The PHC was set up by shadow health secretary Andrew Lansley last year to shape Tory health policy. It is chaired by Unilever chairman Dave Lewis.

Lansley said he would have to examine the report more fully and consider the cost of many of the proposals. However, he confirmed that he supported extending the advertising ban.

While the commission seeks to standardise nutrition profiling, it stopped short of entering the debate over the merits of Guideline Daily Amounts and traffic-light labels.

Front-of-pack nutrition information should cover calories, sugars, salt, fat and saturated fat, the report said, and information should be standardised to include kcal for calories and grams per portion for other nutrients, against GDAs.

However, businesses could continue to apply nutritional evaluation systems such as colour-coding and text on a voluntary basis and in applicable categories, it said.

"People get lots of information about health, but they're not getting clear and consistent support," said Lewis.
