People of higher socioeconomic status choose better diets -- but pay more per calorie
Date:4/30/2009

more costly in terms of $/2000 kcal were also lower in energy density and contained higher levels of nutrients.

Higher quality diets were not only more costly per 2000 kcal but were associated with higher household incomes and education of study participants. Education, rather than incomes was the dominant factor. More highly educated respondents reported higher quality and therefore more costly diets, independent of household income level.

Writing in the article, Pablo Monsivais, PhD MPH, and Adam Drewnowski, PhD, both of the University of Washington, Seattle, conclude, "The finding that higher-quality diets were consumed by women of higher (socioeconomic status) and more costly per 2000 kcal has implications for epidemiologic studies of diet and chronic disease. Nutritional epidemiology has historically been based on the premise that nutrient exposures are directly linked to health outcomes. However, nutritional status is also intimately linked to socioeconomic status, and the findings reported here raise the possibility that the higher monetary cost of nutritious diets may provide one explanation for these observations. Future studies, based on more representative samples, will be needed to elucidate the connections between diet quality and diet cost across socioeconomic strata."
