Washington: Banning ads that promote junk foods among children is likely to cut down their consumption, says a study based on an experiment in a Canadian province.Canada had proscribed fast food ads in its Quebec province between 1984 and 1992, resulting between 11-22 million fewer fast-food meals being eaten per year, according to Kathy Baylis, an economist from the University of Illinois in the US.Advertising bans do work, but an outright ban covering the entire US media market would be the most effective policy tool for reducing fast-food consumption in children, adds Baylis, professor of agricultural and consumer economics at Illinois.Baylis and co-author Tirtha Dhar from University of British Columbia found evidence that the ban reduced fast-food expenditures by 13 percent per week in French-speaking households in Quebec province in Canada.
