What is the impact of advertising on nutrition choices by children?
Seven studies (three randomized controlled trials, two non-randomized controlled trials and one cross-sectional study) met inclusion criteria for the question.
Studies were in substantial agreement that television advertising increases food intake in children, that children prefer the taste of branded foods, that children choose marketed foods whether healthful or not and that advertising could be used to promote more healthful foods. Two studies found that obese children may be more susceptible to food advertising than normal-weight children. One study found that girls may be more susceptible to food advertising than boys.

- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
