Poor access to food and lack of nutrition creates increased health problems for homeless people Prof Ribar tells ABC News Breakfast.
Research from the Melbourne Institute at the University of Melbourne finds that homeless Australians eat only 14 meals per week on average.
Prof David Ribar, who co-authored the report - Food Insecurity and Homelessness - with Dr Nicolas Hérault, using data from the Journeys Home Survey spoke to ABC News Breakfast.
The Journeys Home Survey defines homelessness broadly to include people living without any accommodation at all; people living temporarily rent-free with friends or family; and people staying in boarding houses, caravans or emergency shelters. In this very disadvantaged sample, 97% of the people have been homeless at some point in their lives.
