Just five minutes of advertising of junk foods -- essentially high in saturated fats, sugar, and/or salt (HFSS) -- is enough to coax children and adolescents to consume significantly more calories during the day, according to a study.

The study showed that 7-15-year-olds with just five minutes of ad exposure, regardless of the type of media advertising, can consume on average 130 kcals per day extra, which is equivalent to the calories in two slices of bread.
