Act 30/2019 did not reduce Portuguese children's overall exposure to advertisements for unhealthy foods and beverages. In order to be effective, restrictions would, at minimum, have to cover television advertising during the 7 am-12 pm time band, regardless of the intended recipients of the messages, target public or percentage of children's audience.
