A former advertising manager says that garbage advertising has become a "monster".
Dan Parker, the founder of Living Loud UK, who encourages people to live healthier, worries that advertising unhealthy food and beverages online has become more insidious.
"Ads have become so rooted in online content now that kids and adults do not even know they're being advertised," he said.
Mr Parker, who once worked with major food companies before developing type 2 diabetes-related obesity, spoke during the campaign to launch the IHF's Stop Targeting Kids campaign.
The institution found that seven out of 10 adults here prefer a total ban on advertising non-healthy foods and drinks to children.
Nearly eight in 10 adults believe that advertising is a major contributor to obesity in childhood, which is seen as a major concern in nearly six out of ten.
Mr Parker said the junk sales went to extra lengths to influence children's choices for food.
"Adverse Adware Advertising has become a monster, manipulating the feelings of young people," he said.
A digital marketing explosion and a ruthless exploitation of the gaps in junk emitter settings meant that kids were bombarded daily by impossible to resist advertising.
"But there should be no circumstances in which the marketing of food wipes to children is acceptable," said Parker.
A reference to irishheart.ie/stoptargetingkids calls on the government to regulate digital marketing targeting Irish children and close "gaps in" broadcast restrictions.
The Irish Broadcasting Authority has banned junk advertising in 2013 during child scheduling until 6 pm, when children account for 50% of the audience.
Regulations do not, according to the IHF, work with children aged between three and five years to see more than 1,000 junk advertisements every year on Irish television.
IHF has prompted a ban on the catchment area by 21:00 because many children watch TV between 18:00 and 21:00, even if they do not account for 50% of the audience.
