More than 75% of food-related television ads that kids see promote high-calorie, unhealthy foods and drinks, according to a UConn Rudd Center study published in June. While exposure to such ads has generally declined since a 2007 self-regulation initiative aimed at reducing advertising of unhealthy food targeting kids, children are still seeing many more ads for candy, sugary drinks and fast-food restaurants than they are for healthy foods. This study looked only at television advertising.
With kids spending more time on apps and other nontelevision media, they are likely to be exposed to even more junk food ads. Junk food marketing is a well-known contributor to childhood obesity.
