ObjectivesThe present study investigated associations between income and intake of nutrients and food in adults (n = 11,063) from the fourth Korea National Health and Nutrition Examination Survey 2007–2009.MethodsTo examine relationships between individual dietary intake and anthropometric measures and family income, multiple linear regression models were constructed for each outcome variable. All models were adjusted for age, education, energy intake, smoking, body mass index, and physical activity.ResultsFor men, intakes of protein, calcium, phosphorus, potassium, and vitamin C were lower in low-income compared to high-income groups. For women, intakes of protein and niacin were lower in low-income groups. Lowest income group ate less dairy products in men and less fruits and fishes or shellfishes in women.ConclusionLow-income groups had severe food insecurity and low diet quality compared to high-income groups. The study results will provide direction for public health efforts regarding dietary intakes according to economic status among Korean men and women.

School meals can be an important source of energy and specific nutrients as well as fruits and vegetables. Studies comparing intake from lunch provided at school and lunches carried from home are limited. The purpose of this study was to examine the contribution that school meals made to nutrient, fruit and vegetable intake and meal energy density of children. Lunchroom meal observation procedures were used to collect food intake data from 129 children (ages 8–12 yr) in a suburban Midwestern school. Dietary analyses were completed using Nutrition Data System for Research software and t‐test and general linear models analysis were used to compare nutrient, and fruit and vegetable intake. Children eating school lunch (n=85) had a higher intake of protein, vitamins A, D, and K, and calcium, and a lower intake of energy, fat, carbohydrate, vitamin E and added sugars compared to those who brought a bag lunch from home (n=44). The ratios of mean protein and calcium consumption per minimum values required by USDA regulations for school lunch tended to be higher for children eating school lunch than those eating bag lunches. Children eating bag lunches had a lower fruit and vegetable intake and higher energy density than children eating school lunch. Overall, children who ate school lunch had a more favorable macro and micronutrient and fruit and vegetable intake compared to those who brought a bag lunch from home.
