Sommaire de l'article

CONTEXT
It is well established in the literature that healthier diets cost more than unhealthy diets.

OBJECTIVE
The aim of this review was to examine the contribution of food prices and diet cost to socioeconomic inequalities in diet quality.

DATA SOURCES
A systematic literature search of the PubMed, Google Scholar, and Web of Science databases was performed.

STUDY SELECTION
Publications linking food prices, dietary quality, and socioeconomic status were selected.

DATA EXTRACTION
Where possible, review conclusions were illustrated using a French national database of commonly consumed foods and their mean retail prices.

DATA SYNTHESIS
Foods of lower nutritional value and lower-quality diets generally cost less per calorie and tended to be selected by groups of lower socioeconomic status. A number of nutrient-dense foods were available at low cost but were not always palatable or culturally acceptable to the low-income consumer. Acceptable healthier diets were uniformly associated with higher costs. Food budgets in poverty were insufficient to ensure optimum diets.

CONCLUSIONS
Socioeconomic disparities in diet quality may be explained by the higher cost of healthy diets. Identifying food patterns that are nutrient rich, affordable, and appealing should be a priority to fight social inequalities in nutrition and health.
