Association between energy density and diet cost in children
Ana Patrícia Faria, Gabriela Albuquerque, Pedro Moreira, Rafaela Rosário, Ana Araújo, Vitor Teixeira, Renata Barros, Óscar Lopes, ... Patrícia Padrão
Porto Biomed J. 2016;1:106-11
Highlights

  • The average of the energy-adjusted diet cost in 6-12 years-old children was 2.17€/1000Kcal (SD+0.49).

  • Energy-density diets (EDs - Kcal/g) were calculated by three distinct methods: (1) with food and all beverages (ED1), (2) with food and caloric beverages (ED2), and (3) only with food (ED3).

  • The distributions of the three EDs were statistically different, being higher the ED3 - calculated excluding all beverages (1.15Kcal (SD+0.28) vs. ED2: 1.10Kcal/g; SD+0.24 vs. ED1: 0.99Kcal/g; SD+0.22).

  • Lower energy-density diets (EDs) were associated with higher diet cost in a sample of school children from a Mediterranean country, regardless the differences between the EDs calculated by three distinct methods.
