| There is a common perception that healthy food costs more than less healthy food. In this study we use a demand model for diet quality, rather than the quantity of food. Since in our data, total daily cost and diet quality are both calculated from the foods chosen, we account for the fact that cost is endogenous. We find that while total daily food cost is statistically significant in relation to diet quality, the degree of association is very small. Hence, it does not appear that cost alone prevents individuals in the United States from purchasing a healthy diet. Other factors such as food culture and environment, health behaviours, and demographics are more important. Our findings suggest that the choice to consume a healthy diet is very complicated. |

| We examine the association between food expenditure and overall diet quality using a model where we assumed dietary quality is a function of health conditions, life style choices, total food expenditures, and socio-economic status. We use cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 2001-02 and the U.S. Department of Agriculture (USDA)’s Center for Nutrition Policy and Promotion Food Prices Database. Diet quality is measured using the USDA Healthy Eating Index-2005. Our findings suggest that there is no statistically significant association between total diet quality and diet cost for men, but a small association for women. Compared with diet cost, health conditions, life style choices, and socio-economic... |

| The purpose of this study is to better characterize factors associated with the likelihood of macronutrient excess or inadequacy among U.S adults by modeling parts of the conditional distribution of dietary intakes other than the conditional mean. The risk of dietary inadequacy or excess faced by an individual tends to increase as his or her intake moves from the mean of a nutrient intake distribution toward its tails. Therefore, marginal effects of explanatory variables estimated at the conditional mean using ordinary least squares may be of limited value in characterizing these distributions. Quantile regression is effective in this situation since it can estimate conditional functions at any part of the distribution. Quantile regressions based on data... |

| This paper uses data from national household expenditure surveys to explore whether food insecurity is more severe in South Asia or Sub-Saharan Africa. It employs two indicators of the diet quantity dimension of food insecurity, or the inability to access sufficient food: the prevalence of food energy deficiency and the prevalence of severe food energy deficiency. It also employs two indicators of the diet quality dimension, indicating lack of access to nutritious food: the prevalence of low diet diversity and the percent of energy from staple foods. It finds the regions’ food energy deficiency prevalences to be quite close (51 percent in South Asia, 57 percent in Sub-Saharan Africa). However, the prevalence of severe food energy deficiency, which is more... |

| Background: The nutrition transition occurring in many developing countries may invite the misconception that diets are moving entirely away from undernutrition toward problems of excess. But despite the sufficiency of energy in these countries, diet quality is poor and micronutrient deficiencies often remain. In this context, micronutrient deficiencies may actually contribute to the development and severity of diet-related chronic diseases. Objectives: This paper discusses the potential long-term effects of micronutrient malnutrition in early childhood on obesity and related disease outcomes. The links between early micronutrient malnutrition, stunting, and subsequent short adult stature— emerging risk factors for obesity and associated chronic... |

| Food away from home (FAFH) has been associated with poor diet quality in many studies. It is difficult, however, to measure the effect of FAFH on diet quality since many unobserved factors, such as food preferences and time constraints, influence not just our choice of where to eat but also the nutritional quality of what we eat. Using data from 1994-96 and 2003-04, this study applies fixed-effects estimation to control for such unobservable influences and finds that, for the average adult, FAFH increases daily caloric intake and reduces diet quality. The effects vary depending on which meals are consumed away from home. On average, breakfast away from home decreases the number of servings of whole grains and dairy consumed per 1,000 calories and... |

| A comprehensive model is developed to measure the extent that nutrition knowledge and diet-health awareness, among other factors, influence an individual's Healthy Eating Index (HEI), USDA's measure of overall diet quality. This is the first study that rigorously attempts to examine variation in the index across population groups by controlling for personal and household characteristics and nutrition information levels, as well as test for the endogeneity of nutrition information. Results indicate that one's level of nutrition information has an important influence on one's HEI and that nutrition information and the HEI are simultaneously determined. Other factors explaining variations in HEI's across individuals are income and education levels, race,... |
