Dietary changes needed to reach nutritional adequacy without increasing diet cost according to income: An analysis among French adults.

ABSTRACT:

Objective

To explore the dietary changes needed to achieve nutritional adequacy across income levels at constant energy and diet cost.

Materials and methods

Individual diet modelling was used to design iso-caloric, nutritionally adequate optimised diets for each observed diet in a sample of adult normo-reporters aged ≥20 years (n = 1,719) from the Individual and National Dietary Survey (INCA2), 2006-2007. Diet cost was estimated from mean national food prices (2006-2007). A first set of free-cost models explored the impact of optimisation on the variation of diet cost. A second set of iso-cost models explored the dietary changes induced by the optimisation with cost set equal to the observed one. Analyses of dietary changes were conducted by income quintiles, adjusting for e
