The idea of whether it is possible to be addicted to certain foods is being explored at a public meeting in Dublin.

The Food Safety Authority of Ireland (FSAI) event is being attended by national and international experts who will discuss consumption patterns, and whether food choices can lead to addictive behaviours.

Studies show that two out of three Irish adults - and one in four primary school children - are overweight or obese.

Opening the event, Health Minister Leo Varadkar said that food consumption and health are closely connected.

"It's a challenge for health professionals, for parents, for individuals and for society as a whole. Today's theme of food choices and consumer behaviour is particularly relevant in Ireland today, as overweight and obesity are now a public health priority," he said.

"The same is very true in Ireland. Fortunately, a number of initiatives aimed at tackling obesity are now in place and many more are planned. I hope we can make progress in this important area in the future, particularly through the Government's Healthy Ireland initiative," he added.

Public health nutrition specialist Dr Mary Flynn is speaking at the event.

She told Newstalk Breakfast it is difficult for healthy foods to compete with high fat, high sugar treat foods.
