Just 70 cent a day per child would fund breakfast in schools nationwide for children most in need.
A new report, being published by the Tánaiste today, shows that in schools that run breakfast clubs childrens' attendance, punctuality, energy levels and participation in class are better.
This research was carried out by charity "Healthy Food for All" over an 18-month period in schools in North Dublin.
The group is calling on the Government to provide an extra €1.8m a year to ensure every child attending a DEIS school can start the day with a healthy breakfast.
Project coordinator Sinead Keenan says parents and teachers are also keen to see Breakfast Clubs grow.
