The Canadian Centre for Science in the Public Interest (CSPI) has blasted a campaign launched by a food manufacturers group and broadcasters.

The Healthy Living campaign by Concerned Children's Advertisers - representing McDonald's, McCain Foods and other companies - features workshops and public service announcements encouraging kids to eat healthy and stay active.

The CSPI issued a release saying campaign promotional materials contain no clearly discernible messages about limiting sugar, saturated fat, trans fat, or sodium. "If advertisers are concerned about children's health, they would stop bombarding them with advertisements and promotions to eat candy, salty fries, burgers, potato chips, and sugary soft drinks and breakfast cereals."

Concerned Children's Advertisers was formed in 1990, after Canada's Supreme Court upheld a ban on advertising directed at children under 13.
